its five species : Sisyra is represented by bred specimens of the new 

 species discovered by Dr. Annandale in the freshwater sponges, 

 Spongilla carter i and 5. alba, and whose habits are briefl}' des- 

 cribed by him in a paper on ' ' Some animals found associated with 

 Spongilla carteri in Calcutta" {Journ. Asiatic Soc. Bengal (N.S.),, 2, 

 pp. 187 — 196, 1906). And in addition to this new Sisyra, there 

 are two new genera of Hemerobiidae represented. 



I think I have identified the Hemerobius setulosus of Walker, 

 and it is a Micromus} And since JMcLachlan long ago identified 

 Walker's Hemerobius setulosus as a species of Osmylus, the t^'pical 

 genus Hemerobius appears to be without a representative in India. 

 A second species of Micromus is represented by a poor teneral 

 specimen in the Lefro}' collection, which agrees in size and number 

 of divisions of radial sector, and number of cross-veins in its 

 gradate series with M. australis, Hagen, from Ceylon, and it is 

 probably that species ; colour comparison is impossible. 



The two species of Osmylus in the collection are 0. langi, 

 McL., from Kulu, W. Himalayas, and Kurseong, E. Himalayas; 

 and 0. tuber culat us , Walker, from Upper Assam and from the 

 valley of the Tenasserim river. Lower Burma. 



The new species and genera are described below. 



Sisyra indica, sp. no v. 

 (PI. xxi, fig. I.) 



Male and female specimens, bred by Dr. Annandale from 

 larvae taken on Spongilla carteri. Bred i6th March, 1907. [Com- 

 mon in Calcutta. — A^ A.] 



Length to wing tips 5 mm. Expanse of wings 10 mm. 

 Length of antennae 3 mm. Colour brown, nearly- uniform. An- 

 tennae black. Legs pale. Disc of head and thorax clothed 

 with sparse 3'ellowish hairs. Prothorax wider than long. Abdo- 

 men blackish, except the apex which is somewhat paler. Wings 

 (pi. xxi, fig. 1) smoky hyaline, with brown veins. Costal cross- 

 veins ver}^ unequalh^ distributed, there being about ten in the basal 

 half and only one in the distal half of the space between the 

 base and the stigma. 



The median vein is three times dichotomously forked in the fore 

 wing, but in the hind wing the posterior division of this vein has 

 one forking fewer than the anterior. The ovipositor of the female 

 is straight and stout and blunt at tip, and is about as long as the 

 abdomen is thick. The paired lateral appendages of the abdomen 

 in the male are stout and convex and hairy basall}' on the outer 

 side, but internally they are suddenly extended in a pair of long 

 slender claw-like processes directed inwards and crossed at their 

 tips, these slender horny processes being longer than the basal 

 part from which the}' arise. 



The cocoon of this species is oval in form and 4 mm. long. 

 It consists of fine spun pure white silk, close woven; the outer 



' The specimen is fiom Kulu, W. Himalayas. — N. A.
