no. 3604 GLYPTOSCELIS — BLAKE 25 



separating the species, its lack makes it more difficult to understand. 

 There are three small species of about the same size occurring in the 

 northwest states. One, G. artemisiae, has a shorter and differently- 

 shaped prothorax. The other, G. septentrionalis , has a more bronzy 

 lustre than G. longior, and generally, but not always, the prothorax 

 has more rounded sides, and the pubescence is usually dark brown on 

 the elytra. 



Glyptoscelis coloradoensis, new species 



Figure 24 



Between 6 and 8 mm. in length, oblong oval, piceous shining with 

 a bronzy lustre, antennae reddish brown; prothorax and elytra not 

 too densely or coarsely punctate and covered with dense coarse white 

 and pale yellowish-brown hairs. 



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

 emarginate at antennal sockets, a median line down front ending in a 

 depression, densely and moderately finely punctate over occiput 

 with lower front more coarsely punctate; hairs on occiput yellowish 

 and finer, becoming coarser and white on lower front. Antennae 

 long and slender with the outer joints a little wider. Prothorax 

 slightly wider than long, convex with very slightly rounded sides, 

 punctures anteriorly fine, becoming coarser and more oval in shape 

 near base; pubescence thick, in middle tending to be yellowish, very 

 feathery and white on sides. Scutellum with finer hairs. Elytra 

 slightly depressed below scutellum, a short intrahumeral sulcus, 

 punctation not very coarse, near base horizontally ridged ; pubescence 

 thick and coarse, some pale yellowish-brown hairs intermixed, not 

 closely appressed but somewhat erect. Body beneath densely punc- 

 tate and covered with densely, closely appressed white hairs. Length 

 6-7.8 mm.; width 2.8-4 mm. 



Type: Male, and 35 para types, California Academy of Sciences, 

 10 of these in the U.S. National Museum. 



Type-locality: Paonia, Delta County, Colo., collected by E. C. 

 Van Dyke, June 14, 1926. 



Other locality: Utah: Mt. Carmel, near Zion Canyon, May 30, 

 1935, E. C. Van Dyke. 



Remarks: Krauss has identified this as G. longior LeConte, and 

 it is very similar in size and pubescence but has a wider prothorax 

 and the aedeagus has a well-rounded apex with a small, very incon- 

 spicuous nodule at the tip, quite unlike the aedeagus of G. longior.
