Glyptoscelis peperi, new species 



Figure 12 



From 7 to 8 mm. in length, oblong oval, shining black, antennae, 

 tibiae, and tarsi tending to be deep reddish brown, covered with 

 white and pale brownish hairs intermingled, those on the elytra 

 being coarser than on pronotum, punctation of pronotum dense, 

 deep, and moderately coarse, of elytra coarser near base, a depression 

 below sciitellum and on side below basal callosities. 



Head with interocular space more than half width of head, eyes 

 emarginate at antennal sockets, a median line more or less distinct 

 down front ending in a depression and the lower front slightly produced 

 between antennal sockets; punctation dense and becoming coarser 

 in lower front; covered with white and pale brownish appressed 

 hairs, finer over occiput. Prothorax slightly wider than long, convex, 

 with curved sides and depression along base, shining, deeply and 

 moderately coarsely and densely punctate, the punctures being oval 

 frequently, and covered with white and pale brownish appressed 

 hairs, not as coarse as on elytra and below middle branching hori- 

 zontally toward side in feathery pattern. Scutellum with fine dense 

 white hairs. Elytra depressed about scutellum and with a short 

 intrahumeral sulcus and a depression on side below basal callosities; 

 punctation dense, not very coarse with some horizontal ridging below 

 scutellum; pubescence coarse, white hairs usually intermingled with 

 pale brownish ones. Body beneath densely punctate and covered 

 with white hairs not so coarse as on elytra. Length 7-8.2 mm.; 

 width 3.5-4 mm.

Remarks: This is one of several species liable to be confused with 

 G. albida because of its coarse pubescence. It is slightly smaller and 

 less robust than G. albida, and the pubescence, while coarse, is not as 

 long and is usually composed of brown and white hairs intermingled. 

 The aedeagus is quite unlike that of G. albida, being more rounded at 

 the apex. Krauss has confused this species with G. sequoiae de- 

 scribed from Sonoma Co., but G. sequoiae beside being generally 

 slightly smaller has finer and browner pubescence, and the surface 

 a coppery lustre. Glyptoscelis peperi is also a bit larger than the
