pubescence, legs and antennae reddish brown, prothorax convex, 

 widest at middle and narrowed at base, densely punctate. 



Head with median line ending in a depression in middle of front, 

 densely punctate, punctures in lower front coarser, covered with 

 white appressed hairs, eyes a little emarginate at antennal sockets, 

 labrum reddish brown. Antennae extending below humeri, outer 

 joints considerably thicker, reddish brown deepening to dark brown, 

 covered with fine white pubescence. Prothorax convex but depressed 

 along base, widest at middle, contracted at base, punctation deep, 

 dense, elongated, rather sparsely covered with white and often pale 

 brown hairs. Scutellum with finer hairs. Elytra with a slight 

 depression about scutellum and another below basal callosities, in 

 which punctures show horizontal ridging, punctures deep, not very 

 close and becoming finer towards apex; pubescence not so dense as to 

 hide completely punctures, of mingled pale brown and white moder- 

 ately coarse hairs, giving a pepper and salt appearance. Body 

 beneath densely punctate with dense, white, closely appressed pubes- 

 cence. Legs reddish brown, claw joint with inner tooth near apex, 

 giving it a bifid look. Length 5-7 mm.; width 2.6-3.6 mm. 



Type: Male, in California Academy of Sciences. 



Type-locality: Sacramento, Calif., collected May 28, 1918, on 

 willow by E. P. Van Duzee. 



Other localities: California: Sacramento Co.: Courtland, May 6, 

 1920, F. H. Wymore; Michigan Bar, Apr. 24, 1922, E. G. Thompson. 

 Solano Co., Rio Vista, May 25, 1926. Alameda Co.: Piedmont, 

 May 23, 1921. Butte Co.: near Butte Creek, Chico, Apr. 25, 1922, 

 E. P. Van Duzee. Tehama Co.: Los Molinos, Apr. 1, 1932, on 

 Salix, E. F. Wohlet; also taken at Sacramento by E. H. Wohlet on 

 wild rose, and by Helen Van Duzee, Apr. 24, 1922, A. T. McClay, 

 Apr. 3, 1936, C. M. Packard, Apr. 26, 1920. 



Remarks: This is one of the smallest species of Glyptoscelis in the 

 United States, comparable in size to G. paula, which occurs in Idaho 

 on Artemisia. Glyptoscelis parvula is more rounded and less elongate 

 and has thicker antennal joints. It has been collected on willow 

 and wild rose and seems to be confined to the counties about Sacra- 

 mento, its type-locality.
