Femur, tibia, and metatarsus of anal legs conspicuously flat- 

 tened. First tarsal joint about half as long as the metatarsus; 

 distal di\dsion of tarsus abruptly much more slender than first, 

 consisting of distinct articles t^-pically nine in number and termi- 

 nating in a fully developed curved claw. Femur armed beneath 

 with four spines or processes which are short and distally curved. 

 Tibia with two much smaller spines beneath, one a little each side 

 of middle in the median line. Other joints unarmed (Plate II, 

 Fig. lo).

 and August 25, 1914; sand-hill forest, August 17 and 24, 1914. 

 Five specimens. Type, M.C.Z., 2177. 



The claws of the anal legs in this species are of normal size, 

 being rather better developed than those of N. amazonica Brole- 

 mann, the only other known species of the genus bearing true 

 claws on the anal legs. The present species differs from amazonica 

 in having the joints of the tarsus distinct, or mostly so, in the 

 shorter processes of the femur, the much smaller spines of tibia and 

 their position, and in numerous other details; but the two are 

 ob\dously closely related and may be placed in a separate subgenus, 

 Newportides, subgen. nov., in contrast with the forms with clawless 

 anal legs, Newportia sens. str. 



Newportia lasia, sp. nov.
