This genus must take its place in tlie tribe of the 

 Monocrepidiites. 



The genus Monocrepidius , the type of this tribe , has 

 been established for a group of very numerous insects 

 which have however certain constant characteristics making 

 the genus a very natural one. These characteristics consist 

 in the structure of the fourth joint of the tarsi which is 

 soinetimes dilated and always provided with an inferior 

 fohate appendix , in the protruding shape of the front , the 

 straightness of the prosternal sutures , and the semicircular 

 dilatation of the coxal laminae. 



The new genus here proposed presents all these charac- 

 teristics but with important modifications. Thus the front is 

 protruding but that part which is bent towards the labrum 

 is shaped quite differently from the genus Monocrepidius: 

 it is large and provided with two foveola ; the coxal laminae 

 are dilated on the inner side , but have a square instead of a 

 curvilinear shape; the fifth joint of the tarsi is proportionally 

 shorter and the claws remarkably small. It is, in short, 

 a very curious modification of the type Monocrepidius. 



The new generic division is interesting because it re- 

 presents the Monocrepidius in Africa. The latter are 

 numerous in North and South America, in Asia and in 

 Australia , but in Europe aud Africa they are totally wanting.
