ment semi-circularly emarginate, the last dorsal moderately punctate 

 and with a triangular emargination at tip. 



9. Prosternum more coarsely and sparsely punctured; anterior tibia 

 moderately arcuate, gradually wider to tip, the middle less arcuate and 

 gradually wider to apex, the posterior straight; last ventral longer than 

 in male and with a shallow apical emargination: last dorsal more 

 grossly and closely punctate than in male and with a small apical notch; 

 the head, sternum and femora with more of a purplish lustre; size 

 slightly larger than male, length 12 mm. and breadth 5 mm. 



This species has the facies of C. canrina Horn and is in fact 

 most closely related to it, though it is also sometimes confused 

 with C. monticola Fall. It differs from C. canrina Horn in 

 being more shining and in having the elytra elevations more 

 flattened, the sutural costa less definitely explanate towards the 

 apex, the clypeal emargination less acute, and in not having 

 the apical dilatation of the anterior tibia in the male suddenly 

 constricted- at apex. From C. inonticola Fall it can be told 

 by being generally smaller, more shining, by having the elytral 

 elevations flatter, the prosternal lobe much less distinct, the 

 upper margin of the eyes less close together, the dilatation of 

 the anterior tibia in the male not as broad nor evenly rounded 

 off towards the apex, and by having the space between the 

 suture and the sutural costae more or less checkered by alter- 

 nate callosities and punctured areas, a feature which it some- 

 times shares with C. canrina Horn and which, though super- 

 ficial, is quite characteristic. 



A series of eighty-one specimens has been examined and 

 from the following localities, all in California: Independence 

 Lake, Nevada County, July 12-18, 1916; Donner Lake, Placer 

 County, July 3-8, 1916; Tahoe Tavern, Lake Tahoe, July 21, 

 1916, all collected by R. T. darned: ; Tuolumne Meadows, 

 Yosemite National Park, July 18 and 19, 1916, by G. R. Pilate, 

 and Forest Hill, Placer County. April, i8(;8, by myself. The 

 major portion were secured by Mr. Garnett at Donner Lake 

 on yellow pine, Finns ponder osa Dougl., and at Independence 

 Lake on Jeffrey pine, P. jeffrcyi Vasey. At the same time 

 were also collected one hundred and eighty specimens of typi- 

 cal C. canrina Horn and several typical C. inonticola Fall. 

 This species most likely somewhat replaces C. canrina Horn
