tures fine, feeble, moderately close-set, even and slightly asperulate, the pubes- 

 cence rather short and closely laid ; male with a small glabrous subdepressed and 

 narrowly triangular area at the apex of the first ventral, surrounded by denser 

 vestiture. Length 1.9-2. 1 mm.; width 1. 45-1. 7 mm. California (Sonoma 

 Co. ) sonoma;, sp. nov. 



36 — Pronotum broadly but obliquely red at the sides, the pale area very narrow at 

 the basal angles ; form broadly oval 37 



Pronotum feebly and almost invisibly piceous to pale testaceous at the extreme apical 

 angles only ; elytra with the apical reflexed bead paler, slightly wider mjacinto. .40 



37 — Elytra with a narrow but distinct band of testaceous at the apical margin 38 



Elytra with the mere apical reflexed bead red, the paler tint scarcely extending further 39 



38 — Male with the fifth ventral segment broadly truncate toward the middle, the surface 

 only feebly convex-beveled for a short distance at the middle ; first segment un- 

 modified and punctured throughout ; prosternal carina; widely separated at the 

 apical margin ; prothorax rather small, short and transverse, very finely though 

 distinctly, almost evenly punctured, the sides not quite continuous, rather feebly 

 convergent and evenly, moderately arcuate ; elytra finely though distinctly, 

 moderately closely punctured, polished and smooth. Length 1.6-1.8 mm.; 

 width 1. 2-1. 3. Arizona (Benson and the Gila Valley) — One specimen, from 

 San Diego, is much smaller and has the fifth ventral shorter and more broadly 

 rounded in the female but does not otherwise differ gila;, sp. nov. 



Male with the fifth ventral broadly, feebly sinuate, the surface strongly beveled in the 

 middle, the first segment with an elongate impunctate area at the middle of the 

 apex ; prosternal carinte narrowly separated at the apical margin ; body similar 

 to gila in form and sculpture, the sides of the prothorax more nearly continuous 

 with those of the elytra and more convergent, and the base more oblique at each 

 side. Length 1.8 mm.; width 1.3 mm. Utah (southwestern) — Mr. Weidt. 



decipiens, sp. nov. 



39 — Form less broadly oval, the prothorax relatively smaller, with the sides evidently 

 discontinuous, moderately convergent, evenly and rather feebly arcuate, finely 

 punctured, rather closely toward the sides ; elytra distinctly longer than wide, 

 quite coarsely but not very closely punctured, the pubescence coarse, ashy and 

 conspicuous. Length 2.25 mm.; width 1.6 mm. Colorado (Garland) — Mr. 

 Schwarz garlandicus, sp. nov. 



Form very broadly oval, the prothorax relatively larger, the sides almost continuous 

 with those of the elytra, strongly convergent, evenly but feebly arcuate, the 

 punctures fine but strong, sparse, becoming notably close-set and distinct broadly 

 toward the sides ; elytra not longer than wide, rather coarsely and strongly but 

 not very closely punctate, the pubescence rather short, fine, more decumbent and 

 not very conspicuous. Length 2.2 mm.; width 1.7 mm. California ( Mokelumne 

 Hill, Calaveras Co. ) — Dr. Blaisdell blaisdelli, sp. nov. 



40 — Form rather narrowly oval, the elytra opaque and finely rugulose, finely, closely 

 and asperulately punctate, the pubescence rather short and decumbent ; prothorax 

 strongly transverse, as wide at base as the base of the elytra but with a feeble re- 

 entering angle, smooth, polished, extremely minutely and sparsely punctulate, the 

 sides rather strongly convergent, evenly and distinctly arcuate. Length 1.6 mm.; 

 width 1. 15 mm. California (Sonoma Co. ) advena, sp. nov.
