REVISTON OF ELEODIINT BLAISDELL. 387 



head and prothorax, rather slender, third joint about four times as 

 long as wide. 



Prothorax scarcely a third wider than long; dhc moderately, 

 evenly convex throughout, ver}^ coarsely, deeply, and confluently 

 punctate; afex subtruncate; sides strongl}^ angulate at the middle, 

 thence very feebly arcuate to the apex and broadly sinuate to the 

 base; base subtruncate and nearly equal to the apex in width; 

 apical angles obtuse, not distinctly rounded, not at all prominent; 

 basal angles right and not rounded. 



Elytra at base nearly a third wider than the contiguous protho- 

 racic base, very slightly more than twice as long as the latter, ab- 

 ruptly and obtusely rounded behind when viewed vertically; sides 

 strongly arcuate behind, gradually convergent and straighter thence 

 to the humeri^ which are slightly obtuse but scarcely at all rounded ; 

 disc Avidest behind the middle, where it is from a third to two-fifths 

 wider than the prothorax, feebl}^ convex on the dorsum, strongly so 

 laterally; surface coarsely, densely, asperately punctate, the asperi- 

 ties arranged without trace of order. 



Legs moderate in length, somewhat slender. 



Male and female secondary sexual characters as in pimeMoides. 



Measurements. — Length, 9.2-9.5 mm. : width. 4.3— t.C) mm. A 

 female taken at Verdi, Nevada, has a length of 15 mm. ; width, 7.5 mm. 



Genital characters, male. — As in pimelioides. 



Female. — In the specimens referred to this species and which ara 

 not typical, the genital segment is triangular. 



DoY'sal plate moderately narrow and elongately oblong; apical bor- 

 der feebly oblique with the angle rounded. Apex rather short ; fossa 

 shallow. 



Appendage subspheroidally mammilliform. 



II<d>it(it. — Idaho (Casey); Wj^oming (Casey; Green River, H. F. 

 Wickham) ; Colorado (Buena Vista, July, elevation, 7,900-8,000 

 feet, Wickham). Professor Wickham says that this race is not rare 

 about the roots of gooseberry bushes at Buena Vista (" Coleoptera of 

 Colorado"). Nevada (Verdi, in April). 



Number of specimens studied, 8. 



Type m Colonel Casey's collection. 



Type-locality. — Idaho. 



Diagnostic characters. — Colonel Casey's specimens are small, and 

 to me their most conspicuous difference from pimelioides is the color 

 of the legs, w^hich are brownish and sometimes quite reddish ; in all 

 probability this color is due to the failure of normal pigmentation. 

 This same character is observed in tenehrosa (var. nana) and in 

 caseyi.
