set off by two longitudinal furrows, and on each side toward lateral 

 border a deep, curving sulcus. Anterior margin of prosternum slightly 

 convex on each side, with a distinct darker chitinous edge, bristles 

 three or four on each side. Ventral plates with the usual cruciform 

 impression of which the transverse sulcus is much the finer and curves 

 forward on each side. Last ventral plate with caudal margin very 

 slightly convex. Spiracles broadly elliptic. Coxopleurae but slightly 

 extended caudad, subtruncate or very slightly convex caudally, pores 

 thirty or a few less, faihng by a wide space of reaching caudal margin. 

 Penult legs with numerous long brown setae, no short fine whitish 

 hairs. Anal legs not furrowed above and without teeth or process at 

 distal end of any joints above, though the femur and tibia are obtusely 

 notched at the distal end above, femur bearing numerous stout setae 

 below and above, but no true spines, tibia with a single tooth or 

 spine at distal end below; metatarsus ventrally with a single series 

 of eight or nine teeth, the first joint of tarsus with three of four. 

 Length, 20 mm.

Color fulvous. 



The head overlapping the first tergite or rarely slightly overlapped 

 by the latter, with two fine sulci extending over its entire length, 

 diverging forward, much as in C. galatheae. First tergite with a curv- 

 ing, transverse sulcus; with no longitudinal sulci. Antennae com- 

 posed of seventeen articles. Paired dorsal sulci present from third 

 tergite caudad. Prosternal margin convex each side of middle; with 

 a series of five setae on each side. A few anterior sternites with a 

 cruciform impression, but beginning with the sixth the longitudinal 

 sulcus is not evident caudad of the transverse one, and soon is evident 

 only as a short mark in front of middle. Last ventral plate narrowed 

 caudad, caudal corners widely rounded, caudal margin mesally slightly 

 incurved. Anterior spiracles elliptic. Coxopleurae caudally trun- 

 cate; pores small, numerous, above thirty, not reaching dorsal plate 

 by a wide space; with spines caudally and some among pores. Femur 

 and tibia of anal legs armed ventrally and on the sides with numerous 

 stout spines (similar ones on immediately^ preceding legs soon passing 

 into ordinary setae in going forward), dorsally with ordinary setae,
