California and Oregon. This species has the same forme and 
seulpture as GC. materiarius, but is larger and readily distinguis- 
hed by the different sculpture of the posterior declivity of the 
elytra. 
C. sulcatus Lec. Form, size and sculpture precisely the same 
as in retusus, except that the front is divergently aciculate, and 
the oceiput is sparsely punetured ; the elytra are similarly punc- 
tulate in rows, but the general surface is more distinetly ad den- 
sely rugose; the retuse elevation of the posterior declivity of the 
elytra is but slightly prominent and not denticulate; the hairs 
behind the middle of the elytra are lest numerous. 
Long. 5,5 mm.
