The genital organ resenihlcs that of the latter species, the acetabula, however, being 

 more numerous, about 30 in nunil>er. and unich more elongated. Likewise the genital 

 plates form a narrow strij) on each side of the anterior acetabula. Tn some .specimens there

is a small, roimded, posterior plate, bearing some bristles, which is distinctly separated fnMU 

 the anterior strips. Becau.se of the bad state of preservation of the present species it is impos- 

 sible to decide whether the structure mentioned holds good for all specimens. In some the 

 spot seems to be connected, or nearly connected, with the strip, but more, well-preserved 

 material is needed to settle this question. There are no chitinous sup])orting pieces before or 

 behind the genital organ. 



The male is not represented in the collection. 



Locality. Indian Tibkt: Shimsha Karbu, between Dras and Kargil (K 79), on stones 

 in rapid stream, altitude 2819 m., 22 May, 1932. 



' In the figures tlie ilaws arc seen from a somewhat different position in the two species and thus not exactly 

 comparable.
