A little larger than G. vulneratus Aube, with which it was 
associated and which it resembles very much. Easily dis- 
tinguished, however, by the black labrum, darker under-

tibiae in the $ less triangularly dilated, exterior apical angle 
less pronounced, front tarsi narrower and more attenuated, 
genitalia quite different. In the 2 the prothorax is not 
strongly reticulate, elytra without lateral depression.
