 Habitat in Brasilia. 



Sp. 29. Evania {Hyptiat) animensis. 



Syn. Evania animensis, Spinola, in Rev. Zool. 1840, p. 247. 



Found in gum anime. The fusiform antennae, and presence of 

 radial and cubital cells, seem to separate it from all the other 

 known species. Mr. Kirby also mentions an Evania observed by 

 him in gum. Introd. to Ent. iv. p. 55Q. 1 also possess a distinct 

 species in gum anime, but cannot determine its characters. 



Sp. 30. Evania {Hyptia) crassicornis. 



Syn. Evania crassicornis, Spinola, in Rev. Zool. 1842, p. 189. 

 Habitat in Colombia. 



Obs. Evania tincta, fasciata, histrio, maculata, punctnm, riificoUis, 

 sessilis, and variegata, of the early works of Fabricius, belong to 

 the genus Ceropales. 



Pelecinus, Latreille. 



This genus is at once distinguished from Evania, with which it 

 agrees in the hidden ovipositor, in having the abdomen greatly 

 elongated, that of the females being at least six times the length 

 of the head and thorax, slender and cylindrical, the basal joint 

 being the thickest. In the opposite sex (PI. XIV. fig. 1) the 

 abdomen is about twice the length of the head and thorax, and 

 gradually clavate, the basal joint being very long. Latreille, unaware 

 of this sexual diversity, gave the male, as a distinct species, under 

 the name of Pel. clavator. The abdomen is attaclied to the meta- 

 thorax much lower than in Evania, and the posterior tibiae are 

 remarkably dilated in the females into an elongate ovate mass. 

 In the opposite sex they are more slender. The basal joint of the
