Hob. Port Denison. 



Black, shining ; head very minutely punctured, punctures 

 somewhat scattered, much more crowded on the clypeus ; pro- 

 thorax also minutely punctured, somewhat compressed, and 

 becoming slightly gibbous anteriorly, the sides moderately 

 rounded ; scutellum small, transverse, rounded behind ; elytra 

 rather narrowly ovate, seriate-punctate, the punctures oblong 

 and strongly impressed ; body beneath and legs very glossy ; 

 antennas and tarsi black. Length 4 lines. 



Omolipus (Pascoe, Journ. of Entom. i. p. 127) is allied to 

 the European genus Misolamjms, 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 : — 



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



angustiore ; elytris fortiter seriatim punctatis.

Clypeus a fronte discretus, antice paulo rotundatus. 

 Tibia? anticce apice dilatatse, oblique truncatas. 

 Processus intercoxalis angustatus, apice rotundatus. 



Head rather short, inserted into the prothorax as far as the 

 eyes, regularly convex in front; the clypeus large, a little 

 rounded anteriorly, separated from the front by a strongly 

 arched suture. Eyes narrow, entire. Antennas slightly thicker 

 outwards, the third joint longer than the others, the fifth to the 

 tenth more or less ovate, submoniliform, the last larger and 

 oblong. Mentum pedunculate, trapezoidal, the anterior border 

 slightly biemarginate ; labium small, membranous, transverse. 

 Maxillary lobes narrow, the inner hooked. Maxillary palpi
