 California (San Diego) fidelis n. sp. 



Form nearly similar, piceous-black, the legs pale rufous, the surface 

 rather strongly alutaceous ; head not very coarsely, densely punc- 

 tato-scabrous throughout, the sides strongly converging and nearly 

 straight; prothorax small, nearly as in Jidelis^ but rather less 

 transverse, about four-fifths wider than long, the sides evenly and 

 rather more strongly arcuate, the punctuation throughout nearly 

 similar but slightly stronger; elytra similar but rather more than 

 a fourth wider than the prothorax, with the humeri more widely 

 exposed at base, the punctures more confused, somewhat fine, 

 shallow, slightly muricate and not very close-set, the series very 

 irregular and observable with difficulty except toward base; ab- 

 domen minutely, sparsely punctate. Length 5.5 mm. ; width 

 2.35 mm. Arizona (Peach Springs) debilis Csy. 



16 — Abdomen finely, sparsely punctured medially, not rugulose 17 



Abdomen rather coarsely, not so sparsely punctured even medially, 



its surface shining, but with small inequalities or rugulation... iS 



17 — Body oblong-subparallel, moderately stout, strongly alutaceous, 



piceo-castaneous, the under surface and legs paler and rufous; 

 head rather coarsely, densely, muricately punctate, the sides con- 

 verging and nearly straight ; prothorax slightly though evidently 

 less than twice as wide as long, distinctly narrowed and evenly 

 sinuate at tip, the sides evenly and strongly arcuate, finely and 

 closely punctate, the punctures becoming only moderately coarse 

 but dense and scabrous laterally ; elytra but little more than one- 

 half longer than wide, scarcely three times as long as the pro- 

 thorax and but little wider, very obtusely rounded at apex, the 

 sides feebly arcuate, the series unimpressed, rather strongly, very 

 approximately punctate, the intervals less strongly punctured in 

 very uneven single series laterall}^ ; abdomen convex, finely, 

 sparsely punctate. Length 4. 6-4. 8 mm.; width 2.1-3.2 mm. 

 Texas (El Paso), — G. W. Dunn crassula Csy. 



Body nearly as stout as in C7-assula^ the head neai'ly similar, the pro- 

 thorax shorter, twice as wide as long, evenly but less strongly 

 rounded at the sides, the punctures similarly fine and close-set 

 medially but rather stronger; elytra not quite one-half longer 

 than wide, fully three times as long as the prothorax and slightly 

 broader, the serial punctures similarly strong and close-set, those 

 of the intervals more irregular and deeper; abdomen less sparsely
