The seventh abdominal segment of the male bears a mid-dorsal 

 backwardly directed conical prominence with roughened tip, and 

 the eighth segment bears a somewhat similar process that is, how- 

 ever, ante- apical, thin and flat and squarel}^ truncated on the tip 

 (pi. XX, fig. 2). The ninth segment is moderately produced on the 

 lower side and upturned so as to cover a little of the apex of the 

 abdomen, and bears on its dorsal side a pair of roughened promi- 

 nences, between which rest the tips of the longer prominences of 

 the divided tenth segment. These latter are long-conic, directed 

 forwards and convergent at tips. 



The eighth segment of the female is apparently scarcely pro- 

 duced posteriori}^ on the ventral side, but straight margined, the 

 thin edge of the sternite that covers the openings of the oviducts 

 being very difficult to see. 



Perla duvauceli, Pictet.

Two males in the collection of the Museum from Kulu (Reg. 

 Nos. --*|---), These specimens were pinned, and old, and badly 

 shrivelled, but when boiled in KHO the essential characters became 

 readily apparent. Both agree in size with Pictet's brief descrip- 

 tion, and one of them showed enough of colour pattern for com- 

 parison. 



Length about ir mm,, with antennae 5 mm. and setae 3 mm. 

 additional. Expanse of wings 25 mm. There are two minute 

 ocelli wide apart upon the disc of the head : the antennae and setae 

 are 5^ellow, and pubescent, with hairs of the same tawny colour. 

 The prothorax is narrower than the head, and is transversely oval 

 in form, with all the angles rounded off, the hind angles a little 

 more broadly rounded. The wings are j^ellowish, with weak vena- 

 tion, especially indistinct along the costal margin (pi. xix, fig. 11). 



The ninth abdominal segment of the male (pi. xix, figs, 12 — 14) 

 is ver)^ peculiar. Its posterior prolongation on the ventral side is 

 short, not upturned around the end of the abdomen, and before it 

 on the middle of the segment is a low, broad, hairy elevation bearing 

 a membranous penis at its tip. The tenth segment is annular and 

 exposed, one-third as long as the ninth ; from its hind margin on the 

 dorsal side there grows out posteriorly a short stout downwardly 

 directed spine. To this spine are opposed two claw-like upcurved 

 hooks that arise from the inner side of the base of the setae. 



I confess to much pleasure in identifying this species, which 

 has stood for more than half a century as the onl}' representative 

 of this family known from India. It is destined ultimately to bear 

 another generic name. 



Cryptoperla, gen. nov. 



Eyes hairy ; labial palpi greatly reduced ; face vertical with 

 high frontal ridge ; venation as shown in pi. xix, fig, 15. Other- 

 wise much like Neoperla,
