AMERICAN COLEOPTERA. 239 



sepfment feebly and broadly emarginate. 9 • Seventh ventral with an obtuse 

 broad triangular i)rocess behind. 



Vancouver's Island, Oregon, California; many specimens. 



Fhlvennneus hUmprettsns, Milklin, Bull. Mosc. 1852, ii, 319; and 

 Ihiphxhrm Jaticolh'x^ Lee. New Spec. Col. 55, do not belong to this 

 genus. The front tibiae are not spinose, and they seem from the pres- 

 ence of a distinct scutellum in the former, and its absence in the latter 

 to belong respectively to Ancyropliorus and Trogopldoeus^, 



TfllXOBIVS, Kiesenwetter. 



The species of this genus are of very small size, and linear de- 

 pressed form, greatly resembling in appearance minute Aleocharini 

 (Homafofa. etc.). They are easily known from species of allied genera 

 by the sutural angle of the elytra being broadly and obliquely rounded, 

 so as to leave an angle, in which the wings are visible, except in T. 

 brachi/pfcrus, which is quite anomalous. 



The species seem to be allied to those of Europe, and perhaps ou 

 comparison may profitably be united with some of them as only 

 slightly modified forms. 



Those in my collection are easily separated as follows: the table 

 is made to correspond as far as possible with that given by Fauvel 

 in his excellent work, Faune Gallo-Rhcnane, iii, 118, lor the French 

 species.

 finely punctulate and pubescent, black; elytra brown, legs fuscous. AntenniB 

 piceous, first and second joints stout, third much narrower, the other Joints 

 gradually wider, outer ones (eighth to tenth) distinctly transverse, all of them 

 setose with long stiff hairs; eleventh larger and as long as the two preceding.
