fluiii any of the others except the iifth, which is the shortest; 

 the second, third, and fourth segments decreasing in h'ngth 

 in reguhir order ; the st'cond slightly shorter than the furcal 

 rami, Avhich are armed as in the female. 



Antennse 23-segmented, extending about to the end of tlie 

 cephalothorax, or barely surpassing it. Pdght male antenna 

 geniculate between the 18th and 19th segments; 19th and 

 •20th segments ankylosed ; six segments preceding the genicu- 

 lation rather thickly swollen ; peiniltimate segment produced 

 at the inner apical angle into a Itroad bluntly-rounded process 

 extending slightly beyond the end of the segment. 



Fifth i)air of legs of male l)iramose. Second basal segment 

 of right leg armed above the middle of the outer margin with 

 a delicate hair slanting ni)ward. First segment of outer 

 ramus slightly longer than the width at the base, irregularly 

 trapezoidal, the outer margin forming the longest side ; armed 

 at the outer apical angle with a stout spine about as long as 

 the segment itself and i)rovided on each margin with a nar- 

 row hyaline lamella; just within this, another very minute 

 spine. Second segment irregular in form, the proximal third 

 subquadrate, al)out as wide as the preceding segment, pro- 

 duced at the inner apical angle in the form of a rather large 

 cushion-like pad sparsely covered with delicate hairs ; distal 

 two thirds subquadrate, about half as wide as the proxinnil 

 third, provided on the inner margin with delicate hairs, and 

 armed a short distance above the middle of the outer margin 

 with two spines, one large and one small, similar to those on 

 the preceding segment ; apex of segment armed with three 

 spines fully as long as the segment itself, the outer two 

 straight, the inner curved inward slightly, and each of them 

 provided with a hyaline lamella, the edges of which seem to be 

 plumose. Just posterior to tiie inner apical seta is a short 

 slender spine. 



First segment of inner ramus of right leg irregular in form, 

 about as long as wide, provided on the inner margin with a 

 few fine hairs. Second segment slightly wider than the pre- 

 ceding, barrel-shaped, and slightly longer than wide; pro- 

 vided on the inner margin with a few fine hairs, and at the
