Hind tibia of $ about twice as long as the tarsus, whose proximal 

 joint is about one-eleventh as long as the tibia. Fore-leg of $ damaged 

 in the specimens examined ; in $ the tarsus is nearly three-quarters 

 as long as the tibia, and its proximal joint about one-ninth as long. 

 Relative lengths of tarsal joints: — 'fore-leg, $, 6, 13, 11, 5, and 6 ; 

 intermediate, 5, 7, 7, 2, and 5 ; hind-leg, 5, 7, 7, 3, and 5. Two caudal 

 setae, in g twice and two-thirds (?), in ? thrice and three-eighths, as 

 long as the body. Type, P. cupulatus (in Ileptagenia), Etn. Distrib., 

 China and Tibet. 



Compso;n'etjria, n. g. 

 Hind tibia of $ about twice and a quarter as long as the tarsus, 

 whose proximal joint is about one-tenth as long as the tibia. Fore- 

 tarsus in $ very nearly as long as the tibia. Relative lengths of tarsal 

 joints, in ? .—fore-leg, 18, 23, 16, 8, and 12 ; hind-leg, 10, 9, 5, 3, and 

 10 or 11. Cross-veinlets in the disc of the fore-wing very sparse, 

 disposed in only three transverse broken series. Two caudal setae. 

 Type, C. spectabilis. n. sp. Distrib., Java. 



Compsoneuria spectabilis, n. sp. 



Imago, $ (dried). Ochraceous or pale straw-yellow, varied with fusco-piceous 

 on the thorax. Hind-legs (the others lost) pale straw-yellow; the trochanter, 

 median and apical band of the femnr, base of tibia, and the tarsal joints very nar- 

 rowly at the joinings, black-piceous. Wings vitreous, with pellucid longitudinal 

 nervures, excepting that the costa, sub-costa, and radius towards their extremities 

 are piceous ; cross-veinlets piceous, narrowly clouded with the same colour. Last 

 two abdominal segments pale ; the others edged narrowly above with black at the 

 tips, and with a line on each side near the spiracles, obliquely recurrent from this 

 edging also black ; the third, fourth, sixth, and seventh have, besides, a lanceolate 

 black streak in the middle of the back produced out of the same edging : forceps 

 and belly ochraceous.

Rhithrogena, n. g. 

 Imago. Hind tibia of $ about twice and one-half as long as the 

 tarsus, whose proximal joint is scarcely more than one-thirteenth as 

 long as the tibia. Fore tarsus in J nearly half as long again as the 

 tibia, in $ scarcely upwards of half as long as the tibia ; the proximal 

 joint in $ about one-eleventh, in $ about one-fifteenth as long as the 

 tibia. Relative lengths of tarsal joints : — fore-foot, ^, C*5, 27, 27, 18,
