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.

A new tick, Amblyomma parkeri, n. sp., is described as a parasite of Coendu sp. from S. Paulo, Brazil. Female holotype, nymph and larva are described (Figs. 2 e 3). The n. sp. differs completly from Koch's species Amblyomma longirostre, the common parasite of the Erethizotidae. Standard data for measures of the female dorsal scutum ixodidae are proposed as follows (fig. 1): PA = Antero-posterior; PB = Postero-basal; PM = Postero-median; TT = Transversal; OO = Inter-ocular; OT= Occulo-transversal; SS = Inter-scapular; CC = Cervical; PT = Postero-transversal; ST = Scapulo-transversal; NPT = Normal to the postero-transversal; NST = Normal to the scapulo-transversal. In the female holotype the standard data are as follows: PA = 2.00 mm; PB = 2.26 mm; PM = 1.10 mm; TT = 2.20 mm; OO = 2.26 mm; SS = 0,84 mm; CC = 0.63 mm; SC = 0.12 mm; NPT = 0.20mm; STN = 0.1 mm. Peritrema 0.80 x 0.42 mm with a narrow postero-internal angle and a large, elongated macula. Coxa I with two short spines and all other coxae with only one shorter spine, shortest in coxa IV. Hypostoma spatulated with formula 3/3. Gnathosoma 1.42 mm long and basis 0.63 mm long by 0.84 greatest wide. Palpi with smoth external surface, 1.00 mm long. Type lot No. 4458 from Cotia, S. Paulo, Brazil; in the acarological collection of the Escola Paulista de Medicina, S. Paulo. Ixodes didelphidis, n. sp., differing from Ixodes loricatus Neumann by the shape of the peritremata (figs. 4 a 5) of the male and female and by the number of the punctations in this organ is described form Didelphidae, Muridae and Cavidae. Twenty eight lots were obtained from Anápolis, Goiás, Brasil, where I. loricatus is subtituded by the n. sp. under description. Comparison with NEUMANN'S types of I. loricatus was possible through the courtesy of Prof. A. BRIZARD from Toulouse, who kindly loaned NEUMANN'S material. Female cotypes N° 40 and male allotype N° 531 in the Collection of Ixodidae of the Oswaldo Cruz Institute.

After comparison of the types of Ixodes ricinus aragãoi Fonseca, 1935, with a lot of Ixodes affinis Neumann, 1899, kindly loaned by Dr. Kohls, it was observed that both species differ by the aspect of the dorsal scutm, no large punctations being in the posterior border in the Brazilian material. Therefore is FONSECA'S species maintened as Ixodes aragãoi Fonseca, 1935. Ixodes amarali Fonseca, 1935 was reexamined and confirmed as a valid species. A list of Brazilian species of the genus Ixodes studied by the authors is presented.

An attempt is made to clear the nomenclature of some netropical species of the genus Amblyomma. Amblyomma myrmecophagium Schulze, 1933 and Amblyomma brasiliense guyanense Floch et Abonnenc, 1933, are synonyms of Amblyoma scalpturatum Neumann, 1906. Amblyomma superbrasiliense Schulze, 1941, is cospecific with Amblyomma incisum Neumann, 1906. Amblyomma ypsilophorum Schulze, 1941, is a synonym of Amblyomma cooperi Nuttal et Warburton, 1907.

a) The species Amblyomma tapiri Tonelli Rondelli, 1937 and Amblyomma finitimum Tonelli Rondelli, 1937 are synonymous with Amblyomma cajennense Fabricius, 1787. Both species are based in differences of size, colour, punctations and form of the dorsal shield, presence or absence of ventral plates, size, form and direction of the spine of coxa IV. Such differences prouved to be only variations frequently observed in large lots or in cultures of Amblyomma cajennense. The revalidation of Koch's species Amblyomma tenellum Koch, 1844 and Amblyomma mixtum Koch, 1844 proposed by TONELLI RONDELLI as also of Amblyomma sculptum Berlese, 1888 and Amblyomma versicolor Nuttal et Warburton, 1908 cannot be accepted by the same reasons. b) Amblyomma beccari Tonelli Rondelli, 1939 and Amblyomma latepunctatum Tonelli Rondelli, 1939 are cospecific with Amblyomma scalpturatum Neumann, 1899 the same being true for Amblyomma myrmecophagium Schulze, 1935 and for Amblyomma brasiliense var. guianense Floch et Abonnenc, 1940, as previously stated. c) Amblyomma tasquei Floch et Abonnenc, 1940 is a good species but synonym with Amblyomma romitii Tonelli Rondelli, 1939 which has priority. d) Amblyomma curruca Schulze, 1936 is a synonym of Amblyomma parvum Aragão, 1908. e) Amblyomma deminutivum Neumann, 1899 represents a variation of Amblyomma dissimile Koch, 1844, a species whose internal spine of coxa IV may be poorly developed or even absent. f) Amblyomma nigrum Tonelli Rondelli, 1939 prouved to be synonym with Amblyomma paccae Aragao, 1911 the type representing a blackish specimen of the later species. g) Amblyomma brimonti Neumann, 1913 is a synonym of Amblyomma humerale Koch, 1844.

The female of Amblyomma multipunctum Neumann, 1899 is described for the first time, the species being easily recognized by the unusual formula 5/5 in the female's hypostoma, the formula of the male's being 4/4. A redescription of the male is presented.

Anocentor columbianus Schulze, 1937 is a synonym of Otocentor nitens (Neumann, 1897). Otocentor Cooley, 1938 becomes a synonym of Anocentor Schulze 1937. The correct name of the species is now Anocentor nitens (Neumann, 1897). In Brazil this species was first recorderd by ARAGÃO (in FLOCH and ABONNENC, 1945) in Belém do Pará and by FONSECA (1948) in Goyaz. New records from Minas Gerais and Matto Grosso are presented and a new host, the jaguar, Panthera onca, is added.

A note on the evolution of cow-pox virus in wild animals of Brazilian fauna. We have tried the sensibility of wild animals of Brazilian fauna to the cow-pox virus. The following specimens were submitted to experiences: Procyon cancrivorus, Hydrochoerus capybara, Cavea aperea, Coendu villosus, Didelphis aurita, Bradypus tridactylus, Euphractus sexcintus, Tamandua tetradactylus, Nasua narica, Dasyprocta aguti and Testudo tabulata. In all these animals, - excepting Bradypus tridactylus - we have obtained an infection with incubation (five days), aspect and duration similar to cow-pox of the laboratorial animals (calf and rabbit). In the Bradypus tridactylus howewer, the incubation was very long. Only after 30 days of inoculation we verified the infection with the formation of vesiculae and postulae.
