22 MEMOIRS ON THE COLEOPTERA 



.elytra shining and with the very coarse punctures irregularly dis- 

 tributed, deep, very strongly granuliferous and producing an 

 asperulate sculpture; head much narrower than the prothorax, 

 moderately rugose, net punctate anteriorly, the labrum less abbrevi- 

 ated than usual, the median lobe small, prominent and narrowly 

 truncate, not separated from the lateral parts by the usual sinuses; 

 antennae moderately long, slender; prothorax a fourth wider than 

 long, the sides moderately converging posteriorly, broadly rounding 

 inward basally, the margin attaining the base; surface opaque, mi- 

 nutely lined, feebly rugose peripherally; elytra scarcely one-half longer 

 than wide, oblong, arcuately pointed behind, the margins strongly 

 reflexed, the humeri rather evident; legs notably short. Length ( 9 ) 

 14.5 mm.; width 6.0 mm. California (Tuolumne Co.). Received 

 from Mr. Harris. Male unknown asperatus n. subsp. 



Female as in asperatus in stoutness, less obese than in horni or the two 

 concluding, opaculate, the elytra more shining and with the coarse 

 deep punctures not abruptly denned, contiguous and each with a 

 strong acute granule; head feebly rugulose, the front nearly smooth 

 medially and with some sparse punctures; labral lobe broadly tri- 

 angular and prominent, with truncate apex, the lateral sinuses 

 distinct as usual; antennae slender, moderate in length; prothorax 

 evidently though not greatly wider than the head, moderately 

 obtrapezoidal, less than a fourth wider than long, the sides rapidly 

 rounding inward basally, the margin attaining the base; surface 

 opaque, the fine lines distinct, becoming gradually rugose apically 

 and basally; elytra fully one-half longer than wide, not quite one- 

 half wider than the prothorax, widest just before the middle, where 

 the sides are subprominently rounded, thence gradually narrower 

 behind to the rather obtuse apex; legs rather long, slender. Length 

 (9 ) 15.0 mm.; width 6.1 mm. California (Mariposa Co., June 2, 

 1914) granosus n. subsp. 



Female about as in asperatus in stoutness but with relatively smaller 

 head and prothorax and more inflated hind body, opaculate, the 

 elytra feebly shining, alutaceous; head very feebly rugulose, the 

 impressions rounded, rather shallow; labral lobe strongly advanced, 

 large, feebly truncate at apex; frontal suture bisinuate; prothorax 

 not over a fifth wider than long, the sides evidently but not strongly 

 converging from about apical third the point of somewhat greatest 

 width -nearly to the base, where they become more rounded and 

 converging, distinctly sinuate just behind the middle; margin ex- 

 tremely fine apically, distinctly reflexed basally; surface nearly 

 smooth, with some feeble creases, slightly rugose basally and with 

 longitudinal furrows apically, the transverse impressions obsolete 

 on the disk, the median stria extremely fine and feeble; elytra three- 

 fifths longer than wide, about one-half wider than the prothorax, 

 the basal margin abruptly much wider than the thoracic base and 

 rectilinear, the humeri well exposed and obtusely subangulate; 

 outline rapidly ogival in about apical half, subparallel basally to the 

 humeri; punctures only moderately coarse and well separated, 

 becoming deeper and contiguous toward the sides, the granules
