Notas sôbre Tabânidas brasileiros: I. Fidena longipalpis Enderlein, 1925

The male of Fidena longipalpis End., 1925 is described, and femme femme that were referred to Pangonia incisuralis Macq., 1847 by Lutz in 1909 are now identified as belonging to Enderlein's species. It is emphasised that in his addenda to Macquart's description Lutz gave a characterization which though short is diagnostic for F. longipalpis.

Notas sôbre Tabânidas brasileiros: III. Fidena adnaticornis n. sp

Fidena adnaticornis n. sp. is described from female specimens. It closely resembles Fidena besckii (WIED. ), 1828 and indeed more closely Fidena soledadei (LUTZ), 1911. It can be distinguished from both by the antenna which are so close together that the distance between their basis is less that the width of the first antennal segment; also by the prevalence of yellow hairs on the coxae. In F. soledadei and chiefly in F. besckii the antennae an evidently more separated; they have also few yellow hairs limited to the base extremity of the coxae with prevalence of brown or black hairs. In F. besck the prealar hairs are predominantly yellow ones and there exist yellow hair around the edge of the scutellum, which does not occours in F. adnaticorn and in F. soledadei. In the abdomen the following areas, covered by whit hairs are more extensive in F. besckii: the mid row of white patches on the sternites is more conspicuous and involves the fifth segment; on the sternites instead of stripes the hairs form bands somewhat broader at the middle the respective segment, they may even form triangles with the base as with as the whole segment. Both cotypes of F. soledadei have the hairs damages but, at least, in the 1+2 sternites the areas covered by the white hairs see to be larger than in F. adnaticornis; they have also a higher frons: index : = 2.9.

Considerações gerais sôbre a vegetação do Estado de Goiás: notas preliminares sôbre a fitosociologia do Planalto Central do Brasileiro

Em junho de 1947, fomos convidados pelo general DEJALMA POLY COELHO, chefe da Comissão de Estudos do Planalto Central Brasileiro, para colaborarmos com o Grupo de Geógrafos chefiado pelo Prof. FRANCIS RUELLAN, a quem foi confiada parte dos trabalhos para a localização de novo Distrito Federal da República. A Diretoria do Instituto Oswaldo Cruz, nos incumbiu então de estudar as condições fito-ecológicas de trechos do Estado de Goiás, paralelamente às observações bio-geográficas que teríamos de realizar para a Comissão. Desde 1945 que vimos observando, em viagens, a vegetação do tipo Cerrado, nos Estados de São Paulo, Minas Gerais e Mato Grosso, Outrossim, em notas já publicadas sôbre a vegetação dos Estados de Mato Grosso e Minas Gerais, tivemos a oportunidade de apreciar, ligeiramente, a importãncia do Cerrado como uma climática e o papel que o mesmo desempenha na configuração bio-geográfica do brasil. Queremos salientar, mais uma vez, a grande necessidade que temos de estudar determinados pontos de outras regiões, para podermos apresentar um trabalho ecológico sôbre o Cerrado brasileiro que, apesar de muito bem conhecido sob o ponto de vista da Sistemática, é quase desconhecido quanto ao papel das espécies dentro das associações e sias reações aos habitats. Com os dados ecológicos que possuíamos e com os estudos que realizamos no Estado de Goiás, sòmente nos falta obter uma visão mais ampla das formações e fazer alguns levantamentos sociológicos nas associações do Cerrado dos Estados de São Paulo, Minas Gerais e Baía para completarmos assim, a nossa monografia sôbre a vegetação do Centro Oeste do Brasil. Na apresentação desta nota não poderiamos deixar de agradecer ao Prof. ALFREDO PORTO DOMINGUES e aos componentes do Grupo pos, recebemos contribuição valiosa de todos, que muito fizeram para o bom andamento dos trabalhos de campo. Expressamos também nossos agradecimentos a quantos, direta ou indiretamente, nos auxiliaram, especialmente a Dra. BERTHA LUTZ, a quem devemos o resumo deste trabalho em Inglês.

Anfíbios Anuros do Distrito Federal

The frogs of the Federal District of Brazil are listed and discussed as to habit, biology and ecology. The F. D is situated 22° 54' 24" S. & 43° 10' 21" W Gr. and comprises 1.356 km². Its topography includes sea-shore, maritime scrub, lagoons, plains and marsh, open slopes, forested mountains and great heads of rock. Three thousand feet of altitude are attained at two points. Fifty two different frogs occur in the F.D. Three fifths of them live in open country. Two fifths of these have never been found above the plains; the others range higher but mostly in open country. Their environment offers conditions suitable for average tadpoles and adults. these frogs are more or less unspecialized. There are six genera and thirty species. Two thirds of the latter belong to the type genera of the large neotropical families Bufonidae, Leptodactylidae and Hylidae. Only in the maritime scrub formation are conditions somewhat different. Water for average tadpoles is provided by the lagoons. The xerophytism of the vegetation is, however, so marked that bromeliads growing on the ground provide almost the only appropriate shelter for adult tree-frogs used to sleeping upright on the vegetation. One large Hylid genus lives entirely in them. It is casque-headed and phragmotic, shutting the lumen of the leaf-cup with head used as a plug. Another large Hylid genus shows a lesser degree of the same specialization. (Lutz A & Lutz B, 1939 II). One genus with two species is entirely saxicolous; it lives on wet ledges of rock at all phases of its life history. (B. Lutz 1948). The other two fifths of the frogs from F. D. are montane forest forms. Their environment offers numerous and varied biotopes and is near optimum for adults. There is,however, hardly any standing water available for larvae. These frogs are ecologically diversified. They also show a general trend towards spawning in the adult biotipe, which leads to delayed hatching, semi-aquatic and terrestrial larvae and direct development. (B Lutz, 1948). The author interprets the morphological specialization of the casque-headed Hylids and the biological specialization of the montane forest forms as adaptive. Casque-headedness and phragmosis increase protection against blood-suckers and predators. The humidity of the rain forest permits eggs, embryos and larvae to develop, unharmed, outside their usual, aquatic, environment.

Planta muitíssimo interessante, que se distingue das demais espécies do gênero pela forma pectinada da folha. Dedicamos a linda espécie ao Dr. Adolpho Lutz, eminente sábio, que tanto trabalhou em prol da ciência, no Brasil.

A botânica no Instituto Oswaldo Cruz

The Instituto Oswaldo Cruz, known as Instituto de Manguinhos during the life-time of its foundr, is primus inter pares among the biological research institutions of Brazil. It had a good beginning, for a number of outstanding men were brought together to lay the foundations of a school of research. Future scientists were selected among the most promisin youn medical men. In half a century, it has assumed leadership, in Tropical Medicine and Zoology, and in pure Biology as well. Several of the scientists have been interested in Botany, foremost among them Dr. LUTZ, who always collected plants and studied the flora wherever he went, and left a Herbarium of about two thousan plants. Drs. HENRIQUE ARAGÃO and SOUZA ARAÚJO, also collected in Minas, and gave their collections to Dr. LUTZ. A list of the plants collected by ARAGÃO and LUTZ on the Serra da Mantiqueira, at Pacáu, where Dr. ARAGÃO's family had a fazenda, especially at two interesting points, Morro da Mira and Campos de Safira, is given below. Tribute is paid to Dr. ARAGÃO, Dean of the living research workers of the Instituto Oswaldo Cruz, for the stimulus, which as Director, he gave to non-medical, biological research, including Oceanography Limnology and especially Plant Ecology.

Ensaios de micologia contribuição para o conhecimento das Esporotricoses

The author describes the forms found in material obtained from a human lesion localized in the mouth. The patient was a farmer and the diagnosis unknown. The author found yeast forms, some germinating, resembling those found in the mycosis of LUTZ. It was Sporotricosis and only once, in 96 cases, has the author found these fungous forms in the suspected material. The cultures in Sabouraud glucose and in many other media were positive for Sporotrichum, resembling that described by BENEDEK in 1926 (variety?) principally by the reddish colour of some cultures. The author thinks there is, perhaps, a mutation influenced by the surroundings and the light in certain cultures and that the dark pigment is the dominant one. He considers that the pigment will not do for the differentiation of species and that it is, really, Sporotrichum Schencki-Beurmanni. The author calls attention to the question of diagnosis and studies separately, each of the elements in which his opinion is based, finding that only a macro and microscopic study of the cultures decides the question.

Novos anfíbios anuros das Serras costeiras do Brasil

During the last years, one of the authors has turned her attention, increasingly, to the anuran fauna of the high forested ranges near the sea-board of S.E. Brazil. This has led to the finding of a number of very interesting frogs which do not occur in the lower, mesic, or, occasionally, xeric, open country. One of these forms is presented here. As it did not fit perfectly into any of the known genera, she decided to consult her fellow herpetologist at the National Museum, Mr. Antenor Leitão de Carvalho, who is interested in anatomy. He cleared an adult and a juvenille specimen; the osteological characters found are given below. Joint publication was decided upon, one author contributing her field-notes and the morphological characters and drafting the text, whereas the other contributed the osteology, drawings and measurements. The specific name was also chosen by Leitão de Carvalho, in homage to the late Professor Adolpho Lutz, a pioneer in the study of Brazilian frogs. In regard to the specific designation, the co-author and daughter of Adolpho Lutz wishes to publish the following.

New or rare frogs from the Coastal Ranges of Brazil: eleutherodactylus venancioi n.sp., E. hoehnei n.sp. Holoaden bradei n.sp. e H. lüderwaldti Mir. Rib., 1920

Field-work in the sierras near the sea-board of south-eastern Brazil continues to yield new or rare frogs. Four more of these forms are presented here. Two of them, both new, are put into the genus Eleutherodactylus, to which they belong by their general habitat, morphology, and also by the osteological characters. They differs from the known regional species of this genus only by the wider and shorter disks of some of the digits and the more lanceolate build. The other two species belong to the very little known genus Holoaden, established by MIRANDA RIBEIRO in 1920. One of them is his type-species, H. lüderwaldti, which continues to be very rare. The other, H. bradei, is new. It seems endemic to the Upper Itatiaia and is very plentiful there.

Wyeomyia forcipenis, new species of mosquito (Diptera: Culicidae) from Rio de Janeiro, Brazil

Wyeomyia forcipenis sp.n. is described from specimens caught in Jacarepaguá. State of Rio de Janeiro, Brazil. The male genitalia and the chaetotaxy of the pupa and larva are figured. This species is close to Wy. bourrouli (Lutz, 1905), being distinguished particularly by the shape of the hind plate of the phallosome.
