background typically darker brown or obscure chestnut, with the 

 sides dusky or black, excepting the head and several anterior 

 segments, which are usually light brown, as the last several seg- 

 ments may also be; the wide dark lateral bands embracing the 

 rows of spots leave between them a narrow median d :>rsal light 

 stripe. 



Head with sulcus across vertex sharply impressed, the sulcus 

 terminating anteriorly in a broader, shallow transverse furrow on 

 a level with the dorsal edges of the two eyes. Setigerous foveolac 

 not evident. 



Antenna? slender, clavate, a little shorter than width of body. 



Eyes distinct, subtriangular. Ocelli in types from 17 to 20 

 in 5 or less commonly 4 series, e.g., 5, 5, 5, 3, 2; 5, 5, 4, 3, 1. 



First dorsal plate with lower caudal corner rounded or weakly 

 obtusely angular on ventral side; striate below. Other segments 

 striate above and below cephalad to suture; stria? distinct, moder- 

 ately spaced. Repugnatorial pore circular; tangent to suture, 

 which is not at all angulate. 



Anal scutum obtusely angular, simple. Valves not at all or 

 only very obscurely margined. Anal scale simple, with the caudal 

 margin convex. 



First legs in male small, strongly bent or hamate, as shown in 

 the accompanying figure. 



Gonopods of male concealed. The two pairs widely divergent; 

 anterior ones moderately short; those of the posterior pair con- 

 tiguous, bilobate. Flagellum very long (see figure 28). 



Segments in types 35 to 41. 



Length, 11 — 15 mm.
