Larger than any Eucerus, and, like the following, of totally 
different facies from any of that genus.

EUcHRUS OPACICOLLIS, 7. sp. 
Piceo-fuscus, capite thoraceque alutaceis, opacis, elytris sericeo- 
nitentibus, oris partibus, antennis, pedibusque flavo-testaceis ; thorace 
late cordato, postice sinuatim fortiter angustato, angulis anticis rotundatis,

Larger, and of somewhat different facies from the other Huceri, 
for which reasons it had got astray in my collection among the species 
of Lachnaces. It is allied to Hu. sulcatus ; but differs from all species 
in its minutely and beautifully shagreened or strigose head and thorax, 
unicolorous antenner, &e.
