California (Tndio). Mr. Wickham. 



Allied to (jranulatus Lee, but ver}- much smaller, with much 

 finer and feebler pronotal sculpture and more deepl}' bisinuate 

 pronotal base, much more finel}^ and sparsely sculptured pro- 

 pleurse and several other characters. It is described from the fe- 

 male, and has been compared with the corresponding sex of gran- 

 ulatus. 



X. acutllS. — Moderately stout and convex, somewhat dull, black; head 

 and edges of the pronotum rufescent; antennse and legs brownish-rufous; in- 

 teguments subglabrous. Head three-fourths as wide as the prothorax, nearly 

 one-half wider than long, the sides parallel, rather abrupth^ and strongh' con- 

 vergent before the middle, the apical margin moderately sinuate in the middle; 

 surface somewhat coarsely, densely scabro-punctate, more sparsely granose 

 toward apex ; antennae a little shorter than the head and prothorax, the third 

 joint distinctly less than twice as long as wide and shorter than the next two 

 combined, fourth distinctly elongate, five to eight slightly decreasing in length, 

 the former quadrate, the latter wider than long, club abrupt, the eleventh 

 joint much narrower than the tenth. Prothorax two-fifths wider than long, 

 widest before the middle, the sides very feebly arcuate, becoming straight pos- 

 teriorly, the apex extremely feebly sinuate in circular arc, almost truncate, 

 the angles broadly obtuse and rounded ; base equal to the apex, transverse and 

 feebly arcuate, becoming perceptibly sinuate near the angles, which are acute 

 and prominent but scarcely projecting posteriorly beyond the median parts ;^ 

 disk rather coarsely, somewhat deeply and conspicuously punctate, the punc- 

 tures oval, well separated and distinctly defined, each bearing a very short 

 decumbent hair; interspaces rather smooth and alutaceous, obscurely granu- 

 lato-reticulate. Elytra about one-half longer than ^\4de, twice as long as the 

 prothorax and scarcely wider, the sides parallel and feebly arcuate ; apex con- 

 jointly acutely ogival; sulci deep and rather closely punctate, the intervals 

 dull, densely granulato-reticulate and sparsely asperate. Abdomen sparsely 

 punctate, the propleurte moderately coarsely and densely scabrous. Length 

 4.0 mm. ; width 1.45 mm. 



Arizona. 



The type is a male, having the anterior tibiae rather stout, bent 

 inward at apex and feebly prominent on the inner margin just 

 behind the middle, the abdomen feebU' impressed, more coarsely 

 and closely punctate and more noticeably pubescent in the middle 

 toward base, and the fifth segment broadl}^, feebly impressed. 



This species differs from granidatus principally in its shorter 

 form, much shorter and stouter anterior tibi;i? in the male, coarser, 

 sparser and more distinct pronotal punctures, and in its decidedly 

 shorter third and narrower eleventh antennal joints.
