230 MEMOIRS ON THE COLEOPTERA 



foveae and basally, the eyes well developed and prominent; antennae 

 slender, dark brown, paler basally; prothorax in outline nearly as 

 in nitens but with much more numerous punctures apically and 

 basally, the basal foveae narrower, obliquely sublinear; elytra in size 

 and outline as in nitens, the striae similarly fine and the intervals 

 flat, the discal puncture just behind the middle; hind tarsi similarly 

 very slender but darker in color, much darker than the femora or 

 tibiae. Length (9) 4-5 mm.; width 1.85 mm. New Mexico (Fort 

 Wingate), Shufeldt lateralis n. sp. 



Minute punctulation extending more or less evidently throughout the 

 elytral surface 5 



5 Body rather small in size, subcuneiform, shining, moderately convex, 

 piceous-black, the head almost entirely black, the pronotum palles- 

 cent apically and basally, the elytra pale testaceous, with a large 

 elongate black cloud on each near the suture; under surface black, 

 with pale epipleura, the legs uniformly piceo-rufous throughout; 

 head and prominent eyes well developed, as in all the preceding 

 species, the basal punctulation indistinct excepc laterally, feeble near 

 the fovese; antennae slender, blackish, the basal joint pale; prothorax 

 nearly a: in nitens, the punctulation rather dense apically and basally, 

 the foveae more punctiform; elytra shorter than usual, much wider 

 behind the middle than at base, with fine, very feebly impressed 

 striae and nearly flat intervals, the punctulation very fine and ex- 

 ceptionally sparse, sometimes obsolescent toward the suture, the 

 discal puncture at about three-fifths; hind tarsi very slender though 

 still shorter than usual. Length (9 ) 3-7-3-9 mm.; width 1.65 mm. 

 California (Truckee) monticola n. sp. 



Body unusually elongate, rather shining, very moderately convex, pale 

 testaceous, the head broadly black medially from apex to base, the 

 pronotum with a moderate quadrate central spot of black, the 

 elytra clouded rather broadly with blackish toward the suture behind 

 the middle nearly to the apex, the sutural interval always pale as 

 usual; legs rufous, the tarsi barely at all darker; head large, of the 

 usual form but with the fine punctulation visible throughout, except 

 centrally; antennae wanting in the type; prothorax transverse, 

 rather less narrowed basally than usual but otherwise as in nitens, 

 except that the punctulation is closer and more wide-spread apically 

 and basally and the foveae are feebler and less definite; elytra large 

 and unusually long, more than one-half longer than wide, nearly 

 one-half wider than the prothorax, less inflated posteriorly than 

 usual and but very little wider behind the middle than at base, the 

 sides arcuate; apex circularly rounded, the sinus represented only by 

 a slightly straighter part of the edge; striae finer and more abrupt 

 than in any other species, the intervals perfectly flat, the punctulation 

 only moderately sparse, stronger than usual and equally distinct 

 and close from the sides to the suture, the discal puncture near 

 three-fifths; legs slender. Length (9) 4- 6 mm.; width 1.9 mm.
