//;V ('litifiicd i'*. Female. Body comparatively slender, and, viewed 

 dorsally. of almost equal width throughout, Cephalic segment rathrr large and 

 deep, with the lower edges strongly curved, rostral projection small but distinct. 

 blunt at the tip. All the body-segments finely spinulose at the hind edge dorsally. 

 I'rosome. including the caudal mini, exceeding in length the anterior division. 

 :.ital segment not dilated in front, and almost as long as the 3 succeeding 

 Sjmenta combined; last segment considerably smaller than the preceding one, 

 anal opercie small and finely ciliated at the edge. Caudal rami exceedingly 

 slender and narrow, equalling in length the 3 posterior caudal segments combin. <1. 

 apical setae much elongated. Anterior antenna? fully twice the length of the cephalic 

 segment and gradually attenuated distally, 1st joint about the length of the 2 

 succeeding joints combined, terminal part of about same length, and having the 

 last joint much the largest. Posterior antenna? with the outer ramus rather 

 sl> nder and distinctly Inarticulate, last joint very small and carrying one apical 

 and one hiteral seta. 1st pair of legs moderately slender, outer ramus shorter 

 than the 1st joint of the inner, its last joint nearly as long as the middle one. 

 and armed with .'! daulike spines and 2 geiiiculate setse; inner ramus with the 

 1st joint more than twice as long as the other ~2 combined, seta of the inner 

 ed-e remote from the apex, last joint a little longer than the preceding one. and 

 earning on the tip a moderately long claw and 2 unequal setse. Xataton legs 

 of normal appearance, inner ramus shorter than the outer, especially in the 4th 

 pair. Last pair of Irgv with the distal joint narrouly e.xseited at the end. and 

 only ciliated along the miter edge, marginal setae 5 in number and sowe\\bat 

 unequal; innT expansion of proximal joint rather broad and extending to about 

 the middle of the distal joint, marginal seta 1 ^ in number. 



M:i/< n-rmhling the female in its general appearance, though easih recog- 

 ni/able by the hinged anterior antenna'. 1st pair of legs with the spine inside 

 the jfnd basal joint slightly transformed, being somewhat hamate at the tip. Last 

 pair of legs with the distal joint mm-h smaller than in female and fusiform in 

 outline, having an additional seta inside; inner expansion of proximal joint very 

 slight, with only .'I marginal setffi.
