Genus ANOMADUS Horn (1876). 

 Anomadus Horn, Proc. Amer. Philos. Soc, vol. 15, 1876, p. 21. 

 The monotype of this genus is ohliquus Horn. 



BRADYRHYNCHOIDES, new genus. 



This genus is erected for Brady rhynclius rugicollis Sharp and a new 

 species. The three species placed by Sharp in Brady rhynchufi are 

 placed by Champion in the genus Epagrius Schonlierr. A careful 

 examination of seven species placed by Champion in Epagrius (not 

 Epagrius Sharp, which Champion renames Epagriopsis) disclose two 

 types of eyes. The type species of Bradyrhynchus is hrevirostris 

 Sharp which has an evenly convex e^^e and no constriction of the 

 head behind the eyes. Four of the other species at hand agree as to 

 this character. However, constridus and rugicollis have a deep con- 

 striction behind the eyes, which are strongly convex and sharply 

 truncate behind. In other respects the genus is very similar to the 

 various other genera in the group. 



Type of genus. — Bradyrhynchoides constrictus, new species. 



Table of species of Bradyrhynchoides. 



1. Prothorax strongly foveate; beak medially broadly depressed, frontal constriction 



arcuate (Mexico) rugicollis Sharp. 



2. Prothorax feebly foveate; beak medially sulcate, frontal constriction straight 



(Texas) constrictus, new species.
