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

 the European genus Misolampus^ 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
