'2/80 THE CANADIAN ENTOMOLOGIST. 



A — Form less parallel, the head and prothorax relatively very much 

 smaller in both sexes, the latter but little more than half as wide as 

 the elytra ; other characters nearly as in procerus, except that the 

 prothorax is not wider than long ( £ ), or but slightly so ( 9 ), and 

 with the regulosity still feebler, sometimes almost obliterated ; 

 elytral punctures still finer, very small and decidedly sparse, the 

 fovea; smaller and less evident, the humeri wanting ( q* ) or feebly 

 evident ( 9 )• Length, <£, 15.5-1 7.5, 9 > 18.0-20.0 mm ; width, <$ , 

 5.6-6.4, 9, 6:7-7.0 mm. Tulare Co. (Redwood and Mabel 

 Creeks and Watson Springs). The largest female is less shining than 

 the other examples, in fact almost opaque, and has the head and 

 prothorax relatively somewhat larger, with the sides of the latter 

 rather more rounding basally and with its surface more finely and 

 evidently rugulose parvicollis, n. subsp. 



Foim less elongate, deep black, slightly alutaceous, the head rugose, feebly, 

 obliquely bi-impressed anteriorly, with the median apical surface not 

 smooth, but evidently though finely and confusedly to transversely 

 rugulose, the vertex between the eyes with two small and rounded, 

 smoother and usually well impressed spots. Labrum broadly arcuate 

 medially ; antennae less elongate ; prothorax wider than long, 

 decidedly transverse in the female, strongly obtrapezoidal, the con- 

 verging sides becoming nearly straight basally, more rounded 

 anteriorly, the surface finely but evidently rugose throughout j elytra 

 moderately elongate, convex, barely at all shouldered ( q* ), or very 

 evidently so ( 9 ), the punctures rather small but deep, and widely 

 separated, their bottoms briefly sublineiform. Length, £ , 16.0-17.0, 

 9, 17. 5-19 5 mm.; width, q* , 5.8 mm., 9» 6.6-7.0 mm. Calaveras 

 Co. (Mokalumne Hill), F. E. Blaisdell . .' Blaisdeili, n. sp. 



14 — Form nearly as in Blaisdelli, deep black, rather shining, more so 

 beneath as usual ; head rugose, finely and feebly so in the middle 

 anteriorly, the two spots of the vertex larger, not impressed and with 

 coarser, more vorticiform rugae ; labrum very broadly arcuate 

 medially, the antennae moderate; prothorax obtrapezoidal, wider than 

 long, the converging sides slightly more arcuate basally, strongly 

 rounding anteriorly, the surface evidently though not strongly 

 vermiculato-rugose throughout, the transverse impressions and 

 median stria distinct ; elytra moderately elongate, convex, feebly 

 shouldered (o* ), or rather evidently so ( 9 ), the punctures coarse,
