Omo/i'j)us (Pascoe, Journ. of Entom. i. p. 127) is allied to 

 the European genus Misolamjnis^ from which it may be at once 

 distinguished by the presence of a scutellum and the hooked 

 inner maxillary lobe. The species are all of an intense black 

 colour, more or less glossy ; and, in addition to the characters 

 given of the genus, it may be stated that the claw-joint is un- 

 usually stout, and the epipleura gradually narrows posteriorly 

 and disappears a little way from the apex. The other two 

 species may be diagnosed as follows : — 



Omolqms corvus, Pasc. 1. c. — Ater, nitidus ; prothoracis basi apice 

 ang'ustiore ; elytris fortiter seriatim punctatis.
