 Cynorta oonspersa n. sp. 



Related to C. flavornata, with large yellow spot on outer side of 

 each hind coxa and small dots on the eye-eminence, and a pair of 

 large spots behind on last segment; these last marks, however, are 

 plainly made up of three spots joined together. The dorsum has a 

 great number of small, rounded yellow dots, often marking an eleva- 

 tion, these are most numerous on the sides, two in front of eye-emi- 

 nence on the front margin. The posterior spines are more slender 

 than in C. flavornata and more than their length apart, there are no 

 anterior humps. The tarsal joints are 6, 13, 9, 11 ; femora II and IV 

 are much longer than the body, second joint of mandible scabrous 

 above, the palpal joints not as broad as in that species. 

 . Length 5 mm.; femur I, 8 mm.; femur IV, 7 mm.

STYGNOLEPTES n. gen. 



A Gonyleptid ; the hind coxae larger than others and much broader 

 than first segment of abdomen; all coxae distinct; hind coxae sepa- 

 rated by a triangular plate; spiracles distinct. Palpi not one-half 

 the length of the body, rather slender, with bristles; all legs short, 

 and tarsi with few joints; eye-tubercle broad and low, with a little 

 granule above on each side near eyes. Cephalothorax small com-

 Stygnoleptes analis n. sp. PI. XXVIII, fig. 6. 



Body reddish, palpi yellowish, legs mostly brown, the bases and 

 the articulations pale. Dorsal surface finely granulate. The 

 cephalothorax not more than one-third as wide nor more than 

 one-fourth as long as the abdomen; the dorsal. scutum of abdomen 

 with serrate sides, beyond are four posterior segments, in one speci- 

 men the third and fourth bear a pair of submedian tubercles, about 

 twice their length apart; on the anal plate is a long spine projecting 

 behind the body. The palpi have two bristles on outer edge of both 

 tibia and tarsus, and near base of the femur are two situate on 

 tubercles. The coxae are coarsely granulate, the legs short, none 

 of the femora more than one-half the width of the body; the hind
