 or longish fovea, at least j as long es the joint, for the reception of 

 the base of second Joint, when the antennae bend backward, this peculiar- 

 ity may be traced in several >\leocharini species which have a tendency 

 to lay the antennae back, but in no others is this so strickingly devel- 

 oped as here. So as better to fall into the incision of first joint, the 

 base of second joint is curved.

Furthermore Amarochara is very closely related both to Calodera and 



Ilyobates . Of the t\so following species A. umbrosa i s by Srichson and 



Kraatz assigned to Calodera , and A. forticornis to Ilyobates . However 



the abdomen in A. umbrosa has in contrast to Calodera not four but only 



three at base depressed dorsal joints, ana in A. forticornis the mesor 



sternum has in contrast to Ilyobates no carina in the middle-line. 



Both species live on damp ground under leaves or at the brim of lakes, 



especially woodland lakes, in alluvium.
