Size medium; form robust. Dull brownish-yellow or reddish-brown, 

 with two broad bands of shining fuscous or blackish along the pro- ineso-

 from one another by a rather wide median stripe of pale reddish-brown;

 femora dotted with brownish-yellow, the dots sometimes confluent, some- 

 times in apparently regular rows; hind femora with numerous faint oblique 

 very narrow dark lines; knees fuscous; spines of hind tibiae black at base. 

 Vertex strongly flattened vertically ending in a blunt cone. Fore femora 

 nearly one-third longer than pronotum, male, but slightly longer, female. 

 Hind femora about as long as body, the swollen portion very gradually ta- 

 pering; both outer and inner carinse in both sexes armed with only a few 

 minute spines. Hind tibiaa straight, no longer than the femora, the inner 

 median apical spur as long as basal joint of tarsus. Male with last dorsal

 middle of hind margin (PI. VI, I); subgenital plate broad, deeply and 

 widely cleft, lobes not thickened, each with apex broadly obliquely rounded 

 (PI. VI, g.) Ovipositor about two-thirds as long as hind femora, straight, 

 tapering; inner valves armed as in key and Fl. VIII, q, the terminal hook

Putnam and Vigo counties, Ind., July 20 Oct. 20 (W. X. /?.) 

 Alexandria Co-, Va., Sept. (Daris). This handsome species has 

 been taken in Indiana only in the counties mentioned, where it is 

 most commonly found beneath flat stones near the margins of 

 small streams in upland hilly localities. It reaches maturity in 

 July, probably from specimens hatched in sprint;, though I have 

 taken the young on two different occasions in February. It is 

 sometimes affected by the parasitic hairworm, (lord ins sp. 



The known range of C. latens extends from Connecticut and 

 Ithaca, X. Y., west to Illinois and southwest to Virginia. Scud- 

 der has also recorded it from Texas and Bruner from eastern 

 Nebraska. In Virginia Davis trapped 36 males and 26 females in 

 molasses jars. Hubbell reports it as taken in Cheboygan Co., 

 Mich, and Caudell as mating at Plummer's Island, Md., on 

 Sept. 24.
