evenly elliptical ( £ ) and with barely a trace of humeri, the punc- 

 tures much smaller and sparser, being more nearly as in Dunni. 

 Length, o* > 15.0 mm.; width, 5.1 mm. Monterey Co. 



maritimus, n. subsp. 



9 — Form more elongate and generally more shining 10 



Form stouter and usually duller in lustre, frequently opaculate 20 



10 — Elytra strongly convex; body rather large, usually notably slender, 

 with the head and prothorax smaller as a rule. Species more southern 



in habitat 11 



Elytra less convex, frequently somewhat depressed, the head and prothorax 

 relatively larger. Species of the middle or more northern Sierras. 15 

 11 — Elytra elliptical, widest in front of the middle, moderately convex, 

 closely, not deeply punctate, confusedly so toward apex. Moderately 

 stout, deep black and shining ; head moderate, rugulose throughout, 

 except at the middle of the front, where it is smooth and sparsely 

 punctate, the anterior impressions feeble ; labrum bisinuate, the 

 median lobe arcuately advanced ; antennas moderate ; prothorax with 

 the sides moderately converging to the base, feebly arcuate, the surface 

 rugulose throughout, but not deeply, the median stria very fine, the 

 fine side margins attaining the base. Length, 17.0 mm. Mariposa 



Co. (Coulter ville) intermedins., Leng 



Elytra widest at the middle, convex 12 



1 2 — Elytral punctures small and widely separated 13 



Elytral punctures larger, deeper, more rounded and narrowly though 



clearly separated 14 



13 — Form very elongate, the frontal parts of the head almost smooth but 

 never distinctly punctate, the vertex with two not very widely 

 separated, small smoother spots between the eyes, the spots not 

 impressed. Form more parallel, black ; head and elytra moderately 

 shining, somewhat alutaceous, the pronotum subopaque ; head feebly 

 rugose almost throughout, the frontal impressions large, moderate in 

 depth ; labrum broadly arcuate medially, the antennae long and 

 somewhat slender ; prothorax larger, two-thirds as wide as elytra (^ ), 

 wider than long, the sides strongly converging behind about apical 

 third, parallel anteriorly, the surface finely but distinctly vermicu- 

 late throughout; elytra twice as long as wide, elliptic, without humeri 

 ( £ ), the two series of foveas distinct, the punctures strong, but small 

 and widely separated. Length, $ , 17.5 mm.; width, 6.0 mm. Tulare
