Contribuição ao conhecimento dos crustaceos do Rio de Janeiro: Genero Uca (Decapoda: Ocypodidae)

This paper comprises: 1) A note on Systematists of fiddler crabs from the Bay of Rio de Janeiro, with its new species Uca olympioi, Uca salsisitus, and a new variety U. pugnax var. brasiliensis. 2) Female Uca characterization is easier and infuse certainness when we inquire her third maxillipod. 3) Redescriptions are made for type-locality animals at Rio de Janeiro and nearness. 4) Male characterization become possible through its maxillipod if we lose its quelipod. 5) A historical referendary originating into indigenous dialect « Guarany » about the name Uca and brasilian nicknames of the fiddler crabs. 6) A few Uca species from the Rio de Janeiro determinative keys asked after main distinctions among others species described over the world in paragraph « diagnose diferencial ». 7) A collected material catalogue and some mensurement tables.

Contribuição ao conhecimento das larvas dos Sarcophagidae com especial referência ao esqueleto cefálico (Diptera)

The author publishes a comparative study of eleven species of Sarcophagid flies and gives a redescription of the larval stages of Musca domestica L. as a model. The work was made upon material obtained from Sarcophagidae reared in the Laboratory. Some of them were parasitic flies from Insects and other invertebrates. Protodexia was reared using the domestic cockroach (Periplaneta americana) instead of the Orthroptera or Mantodea its true hosts. The larvae obtained by dissection of female abdomen was reared in flesh or agarhorse serum. The last proceeding is very good since the skins of all larval stages can be conserved for study and it is possible to observe the ecdyses. Some of the larvae prefer dead snails (Bulimulus and Fruticicola) and is able to destroy larvae of other species found in the same molluscs. The first stage maggot can be obtained by dissections of dried female specimens and furnishes very good characters to determine the species and establish the philogenetical relationship of the genera in the family. Th pseudocephalon presents very curious ornaments or grooves in some species (Oxysarcodexia). Sometimes there is a pigmented capsule covering a great part of the pseudocephalon (Titanogrypa). The cephaloskeletal sclerietes have a peculiar shape and constitution for every species, mainly in the first stage maggot.

Contribuição ao conhecimento do gênero Zelurus Hahn (Spiniger auct. ) (Reduviidae, Hemiptera)

In the present paper the authors describe the male and female genitalia of various species of Zelurus (=Spiniger). There were not always obtained reliable specific characters, specially in nearly related species. Futhermore there were studied 59 species and subspecies, from Dutch Guiana, Brazil, Peru, Bolivia and Argentine. New locality records and synonymic notes are given and some allotypes are designated. Eight species and two subspecies, from Brazil and Argentine, proved to new to science.

Contribuição ao conhecimento das paralisias periféricas, múltiplas, uni-laterais, dos nervos craneanos (Síndrome de Villaret)

O autor descreve longamente uma observação dêste raro síndromo de lesão dos troncos nervosos periféricos dos nervos craneanos. No histórico do paciente, apurou a Micose pulmonar, pelo Neogeotrichum pulmoneum e úlcera estomacal, havendo-se curado de ambas. O síndromo nervoso atual foi de origem traumática, por arma de fogo, penetrando a bala no espaço retro-parotidiano e lesando, com maior ou menor intensidade, os nervos glossofaringeu, pneumogástrico, espinhal, hipoglosso e o simpatico cervical esquerdos. Além do síndromo nervoso, teve o paciente um aneurisma da artéria carótida primitiva, que foi ligado.
