Four new species of Trupanea from Chile are described in this paper: Trupanea foliosi, Trupanea chrysanthemifolii, Trupanea footei and Trupanea thuriferae. Morphological and chromosomal characters of adults and immature stages are used in the descriptions and native host plants of the species are also reported.

Some artificial diets were tested and their efficiency assessed from percentage of pupation and emergence, time to emergence, pupal weight, ovary development and maintenance of generation. The best results were obtained with a yeast and starch basal diet. The other products tested were: wheat germ, soybean, fish flour, blood flour and meat flour.

Eustigmaeus bryonemus, sp. n., is described and figured. It was found in Campinas, SP, feeding on mosses. The karyotype, determined on embryonic tissue of squashed eggs, is 2n = 8 (n = 4).

A new species in the genus Ameroseius, viz. dendrovagans, is described and figured. It was collected in bark beetle (Scolytidae, Coleoptera) galleries in Pinus sp. in Minas Gerais, Brasil.

Results of observations on the feeding habit and biology of Ameroseius dendrovagans Flechtmann & Flechtmann are given.

The majid spider crab Nibilia antilocapra (Stimpson), previously known from the West Atlantic coast, between the Lesser Antilles and North Carolina, is reported as found by fishermen on the Rio Grande do Norte coast, Brazil.

The authors have studied the geographical distribution of 33 freshwater prawn species found in Brazil and surrounding areas, as part of a research project which views the development of a national technology for the freshwater prawn culture. The fauna comprises litoral species found in lowlands along the coast, in areas limited at the south by the 15ºC isotherm for the average air temperature of the coldest month, and continental species, which can be separated in tropical, subtropical and temperature ones, whose occurrence areas were delimited by the 20ºC and 15ºC average air temperature of the coldest month.

Diplosolenodes occidentalis (Guilding, 1825) (Mollusca, Gastropoda, Veronicellidae) is redescribed upon the examination of types in the British Museum (Natural History). New characters of external and internal morphohgy are described. A leclotype, is selected.

The physical parameters of vocalizations in Hyla rubicundula are analyzed in the topotypical population and some requirements for this kind of analysis are discussed.

Cercomacra and Schistocichla antbirds (Formicariidae) favor dense foliage and seldom follow army ants for flushed prey, since the ants move through open forest understory as well as through dense zones. Two other lineages, the Drymophila-Hypocnemis lineage (of dense woodland understory) and the Formicivora lineage (of dense bushes in dry or semiopen zones), also cannot follow ants regularly through open forest understory.

Antbirds of the genera Myrmeciza (including Sipia and Myrmoborus), Gymnocichla, and Sclateria hop near or on the ground in fairly dense vegetation, "pounding" their tails downward. Where dense understory vegetation is widespread and ants move in it for long distances, certain of these antbirds become regular ant followers: M. immaculata and M. fortis in cluttered moist foothill forest from Costa Rica to upper Amazonia; Gymnocichla nudiceps in moist cluttered second growth of Central America to Colombia. Where the forest understory is more open, Myrmeciza species follow ants mainly in cluttered patches: M. exsul in lowland forest west of the Andes, M. myotherina east of the Andes. Myrmeciza or relatives that specialize on water-edge or very dense zones rarely follow ants.

Antthrushes (Formicarius, Chamaeza) sometimes walk around swarms of army ants and capture ground prey, but do not follow ants regularly. Among antpittas, only fast-leaping Pittasoma michleri and P. rufopileatum regularly follow ants. Gnateaters (Conopophaga) follow ants little. All these ground-foraging genera are poorly adapted for rapid flying, and failure to follow ants is perhaps due to inability to evade predators or out fly competitors near groups of birds attracted by ants.

The fruit bats Carollia perspicillata and Sturnira tildae (Phyllostomidae) were observed feeding on ripe fruits of Solanaceous plants, Solanum grandiflorum and S. asperum, in the region of Manaus, Amazonas, Brazil. These observations were made between the end of July and the beginning of August, 1978, 1979 and 1981. S. grandiflorum and S. asperum are very common plants in open spaces and paths in the forest. Features of these plant species relevant to dispersal are described. Observations of the feding behavior of bats on ripe fruits showed that these plant species can be considered chirop-terochorous, fitting well within the bat-fruit syndrome. Carollia perspicillata relevant to dispersal are described. Observations of the feeding behavior of Solanum grandiflorum and S. asperum in the Manaus region.

In this paper the concept of coalescence of teeth previously defined for the Tetraodontoid fishes is extended to some other teleostomes. Comments are made on the «dentigerous plates» of non-teleostomian fishes and on the dermal plates bearing odontodes found in some fossil groups.

Refuse from sugar and alcohol industries is rich in organic matter, offering an ideal breeding ground for house-flies. This pest breeds in countless numbers in such substrate, causing severe outbreaks in several counties of the State of São Paulo, Brazil. To control the nuisance, the formula: borax (Na2B4O7) and slaked lime (Ca(OH)2) solutions of 3.18% and 0.35%, respectively, were applied at the channels carrying the waste waters from the alcohol refinery at intervals of 10-15 days. With this method, a very satisfactory control of house-fly populations was obtained at Macatuba, São Paulo, Brazil, between July 1981 and April 1982.

Three new Neotropical genera of Nasutitermitinae, of the group with mandibulate soldiers, are described. Cyrilliotermes, gen. n., is related to Curvitermes and includes C. cupim, sp. n. (type species), C. jaci, sp. n., C. cashassa, sp. n., C. strictinasus (Mathews, 1977), comb, n., and C. angulariceps (Mathews, 1977), comb, n., both C. strictinasus and C. angulariceps being removed from Curvitermes. Alates and soldiers are described for C. cupim, from Brazil, and for C. cachassa, from Suriname, and soldiers for C. jaci, from Suriname; a new locality is reported for C. strictinasus. Embiratermes, gen. n., is related to Armitermes and include E. festivellus (Silvestri, 1901), comb. n. (type species), E. benjamini (Snyder, 1926), comb, n., E. brevinasus (Emerson & Banks, 1957), comb, n., E. chagresi (Snyder, 1925), comb, n., E. heterotypus Silvestri, 1901), comb, n., E. latidens (Emerson & Banks, 1957), comb, n., E. neotenicus (Holmgren, 1906), comb, n., E. silvestrii (Emerson, 1949), comb, n., E. snyderi (Emerson & Banks, 1957), comb, n., E. spissus (Emerson & Banks, 1957), comb, n., and E. transandinus (Araujo, 1977), comb, n., all removed from Armitermes. The creation of Embiratermes, besides being based on morphological characteristics of soldiers, workers and alates, is justified by the defensive behaviour of the soldiers, which is different from that of Armitermes soldiers. Ibitermes, gen. n., which seems to be related to Embiratermes, includes only I. curupira, sp. n., described from a series of soldiers and workers from Brazil. Keys based on the soldier caste are provided for the identification of the 11 genera with mandibulate soldiers of the Nasutitermitinae, and for the species of Rhynchotermes, Curvitermes and Cyrilliotermes. Curvitermes planioculus Mathews, 1977 is considered a junior synonym of C. minor (Silvestri, 1901), syn.n.
