Elytral punctures nearly as in utea^ia^ the head and scutellum much 

 larger and the sides of the prothorax more rounded, pale testaceous 

 in color, moderately sliining, strongly convex; head two-thirds as 

 wide as the prothorax, tinely, moderately closely punctate, the 

 sides strongly converging and feebly arcuate, the angles distinct 

 but blunt, the emarginations distinct, the epistoma but feebly 

 produced, broadly truncate; prothorax a little more than twice 

 as wide as long, somewhat narrower at apex than at base, the 

 sides evenly and strongly arcuate, the basal angles obtuse, not 

 prominent, the punctures very fine and well separated medially, 

 close-set, muricate and larger but not coarse laterally ; scutellum 

 large, rather more than a fourth as wide as an elytral base ; elytra 

 three-fifths longer than wide, gradually, arcuately rounded and 

 obtuse posteriorly, three and one-half times as long as the pro- 

 thorax and, at the middle, distinctly wider, the sides evenly, 

 rather strongly arcuate, the humeri not exposed at base, the punc- 

 tures muricate, fine, moderately close, larger laterally, in great 

 part confused but with uneven and unimpressed series visible on 

 careful examination ; abdomen finely, sparsely punctate. Lengtli 

 4.8 mm. ; width 2.12 mm. Utah (Milford), — H. F. Wickham. 



arnica n, sp. 



Elytra rather finely but more closely and distinctly punctate, the punc- 

 tured series usually obvious almost throughout the length 12 



12 — Epistomal lobe distinctly produced, narrowed and sinuate- 



truncate at apex, the sides strongly oblique, the oblique frontal 

 sutures very deep and distinct. Form elongate-suboval, rather 

 shining and but feebly alutaceous, pale castaneo-furruginous, the 

 legs rufous ; head closely and shallowly muricato-punctate ; eyes 

 rather large and prominent, the sides before them strongly con- 

 verging and nearly straight; prothorax four-fifths wider than 

 long, widest at the middle, but little narrowed and rather feebly 

 sinuate at apex, the sides parallel, evenly and moderately arcuate, 

 the punctures fine and well separated medially, becoming rather 

 coarse, very dense and scabrous laterally ; elytra one-half longer 

 than wide, three times as long as the prothorax and but very 

 little wider, the sides feebly arcuate, the apex obtusely, evenly 

 rounded, the punctures distinct and not very close-set, only 

 slightly muricate, the series not impressed, the intervals with very 

 uneven single series of subsimilar punctures; abdomen rather 

 strongly and closely punctate. Length 4.8 mm. ; width 2.1- 

 2.22 mm. Arizona (Tu9son), — H. F. Wickham. 



lobifrons n. sp. 



Epistoma not sensibly produced, broadly truncate, the oblique frontal 

 sutures shallow and less distinct 13 



13 — Elytral series finely and feebly but obviously impressed, strongly, 



closely punctate, even and very distinct to the apex, the intervals 

 strongly though less coarsely punctate in more or less uneven 

 single scries. Body elongate-oval, only moderately convex, but
