This species was formed for one species from Venezuela, 



VIZ. :- 



Bolbudimyia hicolor, ? , Bigot. 



Bigot describes this striking insect as having 13 or 15 

 rings on the third joint of the antennae, but it is more cor- 

 rectly described as having /ire divisions oidy, of the ordinary 

 size and shape, viz. the large basal division and the four 

 others of about equal size, the last ending in a point. The 

 fly is easily distinguished by the peculiar sha[)e of the first 

 anteunal joint and by the protuberant projection on which 

 the antennae are placed ; the front tibiie are dilated.

Hadrus, Pert)', Del. Anini. Arctic. IJrasil. p. 183 (1830). 



As pointed, out by Williston, Hadrus is preoccupied in the 

 order Coleoptera; he agrees with Schiner that the differences 

 between Hadrus and Lepidoselaga are trivial and that the 

 two should be reunited. They also consider Lepidoselaga and 

 Selasoma very nearly related, the chicL' difference between 

 them being in the presence of metallic scales in the one 

 [Lepidoselaga) and not in the other. The face in Selasoma 

 IS more protuberant and the antennae have the third joint 

 rather broader, with traces of the Tabanus-X'xkc angulation. 



Four species of Lepidoselaga have been described, all from 

 South America ; but as Williston reunites his L paroa with 

 L. albitarsis, Macq., the numl)er is reduced to throe.
