pressed, usually reacliing before the middle, prosternal process strongly asceBding, 

 marginal lines distinct between the coxpe, hind coxal plates strongly narrowed 

 externally and broadly rounded from the trochanters outward. Legs piceous, 

 varied with I'ufous, tarsi with the first joint shorter than the last. Length 

 .25-28 inch ; 5.7-7.1 mm. 



California. Four males in Mr. Ulke's collection not greatly dif- 

 fering in size ; a much larger and more coarsely hairy % , with more 

 slender antennae, in Mr. Austin's. Some of the specimens have three 

 or four broad, faint impressions along the disc of the elytra. The 

 external rudimentary fissure at base of pronotum is not evident. 

 In one of the smaller specimens the submarginal lines are short, not 

 reaching the middle. 



25. Cy. pubesceiis n. sp. — Elongate, moderately slender in the '^.robust 

 in the 9> black or fuscous, clothed with a rather dense cinereous pubescence, 

 bristles very fine and scarcely distinguishable or coar.ser and more evident, legs 

 partly rufous. Antennae normally black, longer than the head and thorax in 

 the % , with the joints broader, much shorter and raoi"e slender in the 9 • Head 

 and thorax rather closely punctulate with scattered, somewhat coarser punc- 

 tures intermixed, or more finely punctulate with the sparser punctures and 

 bristles more distinct; thorax somewhat variable, convex, more narrowed in 

 front, sides broadly rounded or subparallel at middle, or more or less strongly 

 rounded, scarcely sinuate behind, basal lobe feebly bisinuate, impressed in front 

 of and each side of the lobe, plicse moderately long. Elytra wider than the tho- 

 rax, stria; impressed, punctate, intervals slightly convex and punctulate. Beneath 

 finely punctulate and pubescent, coarser punctures evident on the prosternum 

 and behind, submarginal lines of prothorax broad and distinct, but very short' 

 not reaching the middle, pio^ternal process short, compressed behind and strongly 

 ascending, hind coxal plates a little narrowed externally or nearly transverse 

 behind, the free angle rather strongly rounded, legs black or piceous, the tibite 

 varied with rufous, the tarsi rufous, the first joint shorter than the last. 

 Length .25-.33 inch ; 6-8 mm. 



Wyoming (Ulke), two males ; New Mexico, one male ; Colorado, 

 one male one female (Horn). 



Under the above name I have associated five specimens all having 

 a rather long and dense pale cinereous pubescence, the prosternal 

 process short and strongly flexed and the submarginal sutures very 

 short, but distinct. The Wyoming specimens are black ; the three 

 s{)ecimens in Dr. Horn's collection with the elytra brown, possibly 

 from immaturity. In the C'olorado specimens the prosternal process 

 is not so strongly ascending and the last joint of the palj)i is nar- 

 rower than is usual. In all the specimens the last j(.»int of the max- 

 illary palpi is less distinctly triangular.
