SCUDDER. — NORTH AMERICAN CEUTHOPHILI. 31 



1. Ckuthophilus variegatus, sp. nov. 



Blackish fuscous .witii a slight olivaceous tinge, marked with yel- 

 lowish luteous ; there is an interrupted dorsal stripe of the lighter 

 color especially interrupted on the anterior half of the pronotutn ; this 

 is heavily margined by subcoufluent dark blotches or spots, and the 

 dark color prevails over the rest of the thorax, with oblique patches of 

 the lighter tints on the meso- and metanotum, irregular verniiculate 

 blotches of greater or less extent on the pronotum and the lower 

 edges of the descending lobes of the thorax margined not very nar- 

 rowly with luteous ; the sides of the abdomen are prevailingly luteous, 

 but the anterior outer margins are mostly fuscous ; the hind femora 

 have the usual scalariform markings very pronounced, while the other 

 legs are prevailingly luteous and much streaked with fuliginous, 

 excepting the tarsi ; the longer spines are bright luteous, but black 

 tipped. The antennte are two or three times as long as the bodyj 

 moderately stout at the base and gradually tapering, and the legs 

 moderately short. Fore femora distinctly broader than the middle 

 femora, nearly half as long again ($) or scarcely a fourth as long again 

 (9) as the pronotum, and less than half as long as the hind femora, 

 the inner carina with three long spines, the distal subapical and very 

 long. Middle femora with 2-3 long spines on the front carina, one 

 subapical and very long, and on the hind carina 1-2 long spines besides 

 a long genicular spine. Hind femora slightly ($) ov considerably (9) 

 more than twice as long as the fore femora, very broad and stout, dis- 

 tinctly less than three times as long as broad especially in the male, a 

 few very distant and scattered raised points over the whole apical half of 

 the surface, excepting beneath and especially on the inner side above, 

 the outer carina with 3-4 very unequal spines in the apical half, one, 

 sometimes two, much lai'ger than the rest, coarse and as long as the 

 tibial spurs ( <J ) or with a single inconspicuous spine in the pregenicu- 

 lar sinus (9), the inner carina with half a dozen small uniform but 

 irregularly distant spinules, the intervening sulcus rather narrow. 

 Hind tibige straight in both sexes, moderately slender, scarcely ex- 

 panded distally, distinctly but not greatly longer than the femora, 

 armed beneath with a single subapical spine besides the apical pair ; 

 spurs subalternate, the basal before the end of the proximal fourth of 

 the tibia, half as long again as the tibial depth, set at an angle of 40-45° 

 with the tibia and divaricating about 50-60°, their tips considerably 

 incurved ; inner middle calcaria a little larger than the outer, twice as 

 long as the others or as the spurs, and nearly as long as the first tarsal
