SCUDDER. — NORTH AMERICAN CEUTHOPHILI. 99 



II. K. Morrison, coll. S. Henshaw ; 1 (^,4 9, Oregon, and Placer, 

 Kern, and Los Angeles Counties, Cal., mostly from the Kiley collec- 

 tion (U. S. Nat. Mus.). 



The male of this species is remarkable for the surface sculpture of 

 the dorsum of the abdomen, the first seven segments of which, but 

 particularly the second to the sixth inclusive, are densely covered with 

 minute strongly elevated tubercles, besides which on the anterior por- 

 tion of the lirst to the fifth segments and almost crossing the segment 

 is a mesial series of large slightly transverse tumid elevations, rounded 

 anteriorly, truncate posteriorly. I have seen nothing resembling it in 

 any other species, excepting to a less degree in its next neighbor, 

 G. pacijicus ; this and the peculiar characteristics of the outer hind 

 femoral carina make this a very striking species, which I take pleasure 

 in dedicating to my colleague, Mr. Samuel Henshaw. 



54. Ceuthophilus devius, sp. nov. 



Nearly uniform brownish testaceous, subglabrous, with very feeble 

 infuscated obscure blotches especially upon the pronotum, and a fine 

 mediodorsal luteous thread running the length of the body ; surface, 

 especially in $ and particularly on the thorax, very finely sub- 

 corrugate. The antennte are coarse at base (beyond broken), the 

 joints more or less thickened apically. The legs are rather short. 

 Fore femora much less than half the length of the body, hardly a fifth 

 longer than the pronotum, a little stouter than the middle femora and 

 a little less than half as long as the hind femora, the inner carina with 

 a preapical spine and a few (9) or many (<^) spinous points; the fore 

 tibiae with a single median spine on the inner side above, and beneath 

 with 3 (9) or 4 {$) pairs of stout spines. Middle femora with 5-6 

 (9) or H-9 (cj) spines on the fropt carina, the preapical small, at least 

 in the J", the hind carina similarly armed and with a small genicular 

 spine. Hind femora considerably shorter than the body, distinctly 

 more than twice the length of the fore femora, nearly straiglit above 

 in the $ where they are of nearly equal breadtli on the proximal two 

 thirds and are then somewhat abruptly emarginate beneath, less than 

 three and a half times as Ion" as broad in both sexes, the surface 

 glabrous with no raised points excepting sparsely scattered ones on 

 the upper surface in the middle half, the outer carina of both sexes 

 with equal slight denticulations on the constricted jaortion of the 

 femora, the inner carina with larger denticulations throughout (except 

 at base) much larger and more unequal in the ^, where the largest 

 are as long as the tibial spurs, the inferior sulcus narrow. Pliud tibiae
