bronzed, becoming blackish apically in the female, third joint barely as long 

 as the next two. Front densely punctate with two callosities which are larger 

 in the female, flat and cupreous or greenish in the male, more convex and 

 darker bronzed in the female. Eyes rather narrowly separated at summit, 

 their minimum distance apart about two fifths the length of their inner side 

 and subequal to their median width. Clypeus triangularly emarginate, the 

 notch somewhat rounded at bottom. Prothorax nearly twice as wide as long, 

 narrowed at apex and base, sides at middle nearly straight and parallel for 

 a greater or less distance ; median line sulcate, densely punctate in apical two 

 thirds, smooth at base, a very narrow smooth line extending forward a variable 

 distance ; groove limited each side by a broad feebly elevated space, which is 

 smooth in front ; exterior to this two more or less connected and irregular 

 callosities ; surface elsewhere densely punctured. Elytra wider than the thorax, 

 very nearly twice as long as wide, first costa entire, becoming broader at base, 

 the sutural interval punctate throughout ; second and third costse interrupted ; 

 punctured areas densely punctate, smooth areas not very numerous and rather 

 large. Prosternum lobed in front, densely punctate in both sexes ; abdomen 

 sparsely punctate ; anterior femur with moderate tooth, which is serrulate 

 externally ; last ventral with more or less evident submarginal ridge, the lateral 

 margin serrulate. Length 11-15 mm.; width 4.5-6.5 mm. 



Male. — Prosternum flatter, more hairy and a little more finely punctate. 

 Anterior tibia curved, apical dilatation barely one fourth the length of the 

 tibia and arcuate in outline, the tibia slightly narrow at the base of the dilata- 

 tion but not obviously sinuate ; middle tibia feebly arcuate beyond the middle, 

 gradually broader at apex ; last ventral segment deeply semicircularly emargi- 

 nate ; last dorsal with a moderately broad median notch. 



Female. — Prosternum less flat, less hairy, and usually more coarsely and 

 a little less densely punctate ; tibiae unmodified, last ventral with a small 

 apical emargination, last dorsal more densely punctate and with a smaller 

 narrow median notch. 



Described from six males and four females in Dr. Fenyes' and 

 my own collection. It occurs on pines in the California Sierras, 

 about Lake Tahoe and in the San Bernardino and San Jacinto Mts. 



As I have pointed out previously, this species is the one which 

 best fits Dr. Horn's description of calif ornica, and I might about as 

 well have referred to that description and saved myself the trouble 

 of writing a new one, but for the desirability of having here a com- 

 plete description for comparative purposes. The true calif ornica 

 differs distinctly in its nonlobed prosternum, narrower and longer 

 tibial dilatation, and more widely separated eyes. 



The form of the prothorax is somewhat variable in monticola, as 

 it is in most if not all all of the allied species; it is usually as above 

 described, but in some specimens the sides are nearly straight and 

 convergent from the post-apical dilatation to the base.
