adults than in the two-thirds grown young, where they are sub-equal 

 in size. The black markings at base of tibial spines, used by Scudder 

 in his key, are seldom present in the adults and are therefore of no 

 value as a distinguishing character. I have, in recent years, taken 

 numerous specimens of the large form mentioned in my former 

 paper, and described herewith, in company with the immature forms 

 described by Scudder, and there is no doubt but that the two are the 

 same. 



C. latens has proven to be a rather common species in Indiana, 

 having been taken in Vigo, Putnam, Crawford, Kosciusko and Steu- 

 ben counties. It is most commonly found beneath small chunks or 

 flat stones in rather dry sandy localities. Sometimes a half dozen 

 will be found in company beneath the same shelter. It reaches ma- 

 turity about July 20th, probably from specimens hatched in spring, 

 though I have taken the young on two different occasions in Febru- 

 ary. The species is sometimes affected by the parasitic hairworm, 

 Gordius sp.f According to Scudder, it ranges from "New York to 

 Texas."

Pale, reddish brown, the hind border of each segment with a dark 

 browTL band, the pronotum with a similar band on the front margin, 

 and an indistinct, dark median band connecting the two. Face pale 

 with usually a black dash below each eye, and a shorter median one. 

 Antennae brownish yellow, paler toward the tip, of exc'essive length, 

 averaging four times the length of body. Legs all very long and 

 slender. Front femora, in the specimens at hand, double the length of 

 the pronotum, with two to five spines on the lower front carina. Mid- 

 dle femora shorter than the anterior with both of the lower c'arinae 

 armed with three or four distinct spines. Hind femora rather slender, 

 nearly as long as the body, the lower, outer carina prominent; the 

 inferior sulcus narrow and of average depth; both margins armeH 

 with numerous small spines, those on the outer carina of male double 

 the size of those on the inner. Hind tibiee straight, longer than the 

 corresponding femora. Hind tarsi two-fifths the length of the tibiae. 

 Cerci slender and tapering, nearly half as long as hind femora. Ovi-
