322 CASEY 



spaced, generally in less even single series, confused near the 

 suture; abdomen coarsely, rather closely punctured along the 

 middle, but more sparsely so thence to the sides. Length 4.1 

 mm.; width 1.S5 mm. Texas (El Paso), — II. F. Wickham. 



vapida n. sp. 



19 — Oblong-oval, stout, pale brownish-testaceous, the legs more flavo- 

 rufous ; head rather coarsely, densely punctato-scabrous, the sides 

 strongly converging and nearly straight, the lateral lobes narrowly 

 rounded at tip, the epistoma very broadly and moderately though 

 distinctly produced and truncate, with its sides very oblique, the 

 oblique sutures fine but distinct; prothorax transverse, not quite 

 twice as wide as long, but little narrowed but deeply sinuate at 

 apex, widest at the middle, the sides evenly and strongly aicuate, 

 the suiface slightly alutaceous, minutely, rather closely and muri- 

 cately punctate, becoming rather coarsely, very densely punctato- 

 scabrous laterally ; elytra not quite one-half longer than wide, 

 three times as long as the prothorax and a fifth wider, obtusely 

 rounded at apex, the sides broadly and distinctly arcuate, the 

 series of close-set and rather small but deep punctures unim- 

 pressed and slightly irregular, the intervals with confused and 

 sparser but scarcely smaller punctures; abdomen minutely, 

 sjjarsely punctate. Length 5.3 mm. ; width 2.7 mm. California 

 (probably near Yuma). [ = sodalis Csy. nee Horn, olim]. 



incisa n. sp. 



Oblong-oval, the elytra rather dilated posteriorly, piceous-black, the 

 legs rufous ; head coarsely, densely punctato-scabrous and dull, 

 the frontal margin evidently biemarginate, the epistoma produced 

 slightly and rectilinearly truncate, the sides before the eyes evenly 

 converging and moderately arcuate ; prothorax small, very nearly 

 twice as wide as long, strongly narrowed and moderately sinuate 

 at apex, widest and subinflated near basal third, the sides sub- 

 evenly, rather strongly arcuate, especially toward base ; punctures 

 coarse, scabrous, slightly smaller and separated mediall}', very 

 dense and rough laterally, the surface with a deeply impressed 

 line along the basal margin throughout the width ; scutellum well 

 developed, somewhat punctate ; elytra one-half longer than wide, 

 between three and four times as long as the prothorax, and, pos- 

 teriorly, distinctly wider, the sides broadly arcuate, the apex 

 rapidly and obtusely ogival ; punctures very coarse, strongly 

 asperate, deep and close-set in rather confused and uneven unim- 

 pressed series, the single series of the intervals similarly coarsely 

 and asperately but less closely punctate, causing the coarse 

 sculpture to be very conspicuous, although the interspaces are 

 polished, all series continuing unmodified to the apex ; abdomen 

 more finely, not very sparsely and subasperately punctate medially. 

 Length 4.6-5.3 mm. ; width 2. 1-2. 38 mm. Colorado (Salida), 

 — H. F. Wickham aspera n. sp. 



20 — Apical angles of the head narrowly rounded, the sides converg- 

 ing and straighter before the eyes; color generally dark 21
