gined; upper surface smooth with extremely faint longitudinal stria- 

 tions. Caudolateral corners of paranota caudal to 14th, becoming 

 increasingly produced. 



Median projection of anal segment subtriangular in dorsal aspect, 

 longer than broad, the tip slightly truncate and bearing several long 

 setae. Anal valves glabrous, the mesial margin of each produced into 

 a low ridge but no other obvious sculpture. Preanal scale broadly 

 triangular, wider than long, ^vith a median and two smaller lateral, 

 setiferous, tubercules. 



Sternal areas of metazonites essentially flat or slightly concave, not 

 raised above level of prozonite but set off by a broad, shallow, sharply 

 defined interzonal furrow. Sternites slightly produced at base of each 

 leg, becoming subspiniform toward the rear of body. Sternites gla- 

 brous or at most with six or eight scattered setae on some of the 

 segments just behind the gonopods. Coxae and prefemora with acute 

 conical distoventral spines, these becoming longer caudad; these leg 

 joints also with numerous long slender setae on the ventral side. 

 Femora nearly glabrous, slightly clavate, shorter than coxae and pre- 

 femora combined. Postfemora and tibiae equal in length, the latter 

 of a lesser diameter and about half as long as the moderately setose 

 and subcylindrical tarsi. Tarsal claws of anterior legs of males long, 

 sinuous, with a distinct sharp carina along the dorsal side. 



Sternites between 3d legpair produced upward into two slender, 

 digitiform lobes, those between 4th, 5th, and 6th legpairs in the form 

 of low rounded eminences. 



Pleurites coriaceous, somewhat obhquely longitudinally striate in 

 some specimens, the caudal margin distinctlj^ set off. No tubercules, 

 granules, or clusters of spines. 



Sternal aperture of 7th segment of males large, transversely oval, 

 widest in front of the middle, strongly margined laterally and between 

 the coxae of the 8th legpair. 



Gonopods freely movable, the coxae separate and connected only 

 by a strong band of connective tissue. In situ, the main axis of the 

 telopodite blade lies at a right angle to that of the body, the gonopods 

 at rest thus have the blades overlapping and often interlocked. Coxal 

 apodeme moderately long, slightly enlarged distally. Coxae without 

 special processes. Prefemur swollen, densely setose, with a prominent, 

 upright, wedge-shaped prefemoral process. Telopodite blade slender, 

 evenly curved into almost a complete circle, without trace of division 

 into femur, tibia, and tarsus, Telopodite distally slightly expanded, 

 with a small thin subtriangular tooth (process A). 



Tergites glossy brownish black, with caudolateral two-thirds of the 

 paranota, anterior edge of collum, and tip of anal segment bright 

 lemon yellow. Underparts yellowish tan, somewhat burnished in
