Rock paintings of mammals have been studied in five of the 243 localities contained within the 270,000 km² Archeological Region of Central, Bahia. From features of external morphology, it was possible to recognize 11 mammals represented in the paintings: for five, to attribute the species; another five, the genera; and, for one, merely the family. This study aims to underline the importance of prehistoric man's contribution, by way of these rock paintings, to our knowledge of the mammals depicted, both taxonomically and in terms of their distribution within the bounds of the Project in the State of Bahia.

Deois mourei, sp.n. (= Deois picklesi; Sakakibara, 1979) is described from Curitiba, Paraná, Brazil. Menecphora coerulea Lallemand, 1924 is transferred to Deois Fennah, 1948.

The present catalog is an inventory of names proposed in Erotylidae (from family through subspecies) ocurring in the Neotropical Region, up to the present date (1988). It updates the nomenclature of included taxa, adds taxonomic units proposed after the Kuhnt's Genera Insectorum (Kuhnt, 1909) and includes abbreviated references to the literature, which are fully cited at the end of this catalogue. The systematic order follows Kuhnt, 1909, and afterwards, the position given to each taxa by the original author.

Attrativeness of differents baits (fish, faeces and banana) upon ovarian development fases of Calliphoridae and Sarcophagidae was evaluated. The insects were captured in Distrito Federal (urban area) and Rio de Janeiro city (beach, zoological garden, urban area and Tijuca forest). The most frequent species captured were: Calliphoridae - Chrysomya megacephala (Fabricius, 1794) 78,9% and Chtysomya puloria (Wiedemann, 1818) 5,4% - and Sarcophagidae - Sarcophagula Wulp, 1887 2,3% and Peckya chrysostoma (Wiedemann. 1830) 2,2%. Fish was more attractive to females of Calliphoridae flies in intense ovarian vitelogenesis, although banana atracted more flies with mature eggs. Faeces and fish were more atractive for Sarcophagidae in the beggining of vitelogenesis.

Great part of lhe avaiable data about snakes reprodution refers to species coming from subtropical and temperate regions. In Brazil, the data is rather rare and can be found in various works where information is restricted. Results from studies developed with five viviparous snakes - Crotalus durissus cascavella (Wagler, 1824). Bothrops erythromelas(Amaral, 1923), B. leucurus (Wagler, 1824), Helicops leopardinus (Schlegel, 1873) and Thamnodynastes strigilis (Thiinberg, 1787) - which come from the Northeast of Brazil (Bahia) are described. Data about pregnancy and birth, number, sex ratio, length and weight of neonates is given and discussed.

Six new Micrathyria Kirby, 1889 larvae from Brazil are described and compared to those described by SANTOS (1968, 1972, 1978) and NEEDHAM (1943). The distribution of the species is studied based on material deposited in colection of Museu Nacional, Universidade Federal do Rio de Janeiro (MN-UFRJ).

Bithoracochaeta maricaensis, sp.n. from Barra de Maricá, Rio de Janeiro, Brazil, is descrihed and illuslrated.

The resulls of the protargol's technique and Feulgen's reactions on ciliates of the genus Entodinium Stetn. 1859, Diplodinium Schuberg. 1888. Eodinium Kofoid & MacLennan. 1932, Eudiplodinium Dogiel. 1927 and Ostracodinium Dogiel. 1927 are presented. The ciliates were obtained from samples of bovine's ruminal content.

Two Malaise traps (TOWNES 1972 model) were installed on an island (the "Ilha do Mel") in the Bay of Paranaguá, from September, 1988 to August, 1989. at two sites denominated "Fortaleza" and "Praia Grande", for collection of insects. Apart from collection of insects (Fortaleza: 62.924 individuals; Praia Grande: 38.868 individuais), graphical analysis were limited to those Orders wich occurred concomitantly at the two collection points in ali months: Collembola. Hemiptera. Homoptera. Coleoptera. Lepidoptera. Diptera and Hymenoptera. It was concluded that the Malaise trap is selective for Diptera. Hymenoptera and Lepidoptera. and proved to be efficient in measuring abundance, in obtaining information regarding the seasonal variation of insects, and in comparing the entomofauna of different geographical localities.

Two Malaise traps (TOWNES' 1972 model) were installed on an island (lhe "Ilha do Mel") in lhe Bay of Paranaguá, from September, 1988 to August. 1989. at two sites denominated "Fortaleza" and "Praia Grande", for colleetion of insects. At "Fortaleza". 1,715 individuais of Tabanidae were captured, representing 3.20% of all Diptera captured in this site, while at "Praia Grande" 1,420 individuais of the same family were captured, representing 5,06% of ali Diptera captured there. In "Fortaleza", Tabanidae is represented for 10 species, while in "Praia Grande" it is represented for nine species. Dichelacera alcicomis (Wiedemann. 1828) was the most abundant species at two sites, representing 87,52% and 66,69 % of all Tabanidae captured at "Fortaleza" and "Praia Grande", respectively. The grealest number of individuais occurred in November, the month with the lowest relative humidity associated to small pluviometric precipitation, just after a month with high relative humidity associated to a high pluviometric precipilation.

The female of Asaphobelis physonychus Simon, 1902 is described for the firstl time. Some new comments about the male are provided and the palpus is illustrated.

Radiodiscus vazi. sp.n. is described. Synonymizations of Zichogyra cleliae Weyrauch, 1965 under Radiodiscus pilsbryi Scott, 1957 and Radiodiscus patagonicus (Suter, 1900), comb.n. - non Radiodiscus patagonicus Pilsbry, 1911 - and Radiodiscus iheringi (Ancey, 1S99), comb.n. - non Radiodiscus jheringi (Thiele, 1927) - are proposed with Radiodiscus bolachaensis. nom.n.

Tylanthidium, gen.n. is proposed to a new species from the north brazilian state of Amazonas - Tylanlhidium tuberigaster, sp.n. - characterized by the absence of arolia and of interalveolar carinas, the peculiar scutellum almost triangular and by the genal preoccipital carinae; the males with the apical border of the mandibles deeple sinuate and the distai tergum densely hairy bellow. Michanthidium nom.n. is given to Gnathanlhidium Urban,. 1992 (non Gnathanthidium Pasteels, 1969).

The aim of lhe presenl work is to descrihe the biological cycle of the Apiomenis lanipes (Fabricius, 1803) (Hemiptera, Reduviidae) on lahoralory conditions. Adults of Drosophila sp. (Diptera, Drosophilidae) and Ceralitis capitula (Wiedemann, 1824) (Diptera. Tephritidae) was offered for hug feeding (nymphs and adults). The developmenlal of the entire cycle (egg to adult) was 288.26 days and 294.85 days for males and females, respectively. The duration of egg stage and nymphal stage was 23.5 days and 269.02 days, respectively.

This species from the Mata Atlântica resembles Melipona lateralis Erichson, 1848 and M. seminigra Friese, 1903 from the Amazonian Region. It can be easily distinguished from the first and its nearest relalive, M. scutellarís Latreille, 1811 by having a more shining mesoscutum and from the second by the yellow facial markings.

Rhynosielis, gen.n. is proposed as new genus for Anthidium multiplicaium Smith, 1879. It has in commom wilh Hoplostelis a strong basal tooth on upper border of mandibles. Main differences with Hoplostelis are: mandibular shape, configuration of mandibular teeth on apical border, a rounded tubercule on upper clypear third, mesoscutum posteriorly bigibbous, scutellum transverse-bigibbous, preepisternal carina laminate and almost complete, basal portion of propodeum without foveae and a median carina on last three terga.
