Ferninae pygidio minus gibbo, tarsis posterioribus minus 

 elongatis, unguiculis simplicibus. Long., 8-8J I. ; lat., 4J 1. 



This species seems too close to A. subcequalis to be justifiably 

 made into a new genus ; nevertheless it differs in several not un- 

 important structural characters, notably in its longer and more 

 slender tarsi (there being also a greater difference in length be- 

 tween the hind tarsi of the sexes, the basal joint of the hind 

 tarsi being moreover but little dilated externally and not much 

 more in the female than in the male). This is a perplexing 

 character which makes Asemantus very difficult to place among 

 the Dynastid genera, since in M. Lacordaire's arrangement the 

 male of A. subcequalis would be a Pentodontid and the female a 

 Pimelopid and both sexes of the present species have Pentodontid 

 structure of the hind tarsi. Other characters in which this 

 species differs slightly from the generic characters I attributed 

 to Asemantus are as follows : — The carina separating the clypeus 

 from the hinder part of the head is a little better defined than 

 the expression " clypeus a f ronte vix distinctus " implies, and the 

 anterior excavation on the prothorax cannot be called " large." 



Among the examples before me are two much smaller than the 

 rest (long. 6 1.) which however do not seem to differ otherwise 

 from the larger specimens.
