1909. J J. G. Needham : Notes on the Neurot>tera. 205 



Thorax yellow beneath, somewhat darker above and tinged with red- 

 dish on the principal convex areas. Legs pale yellow, the tips of the 

 tarsi darker. Wings hyaline with yellow veins, otherwise unmarked. 

 Abdomen yellow beneath, somewhat darker above, and clothed 

 with scanty yellowish pubescence. The paired lateral appendages 

 short and scarcely forcipate. There is a median ventral appendage, 

 three times as long as the laterals, jointed at two-thirds its length, 

 and with the tip strongly reflexed at this joint. 



Eremochrysa marmorata, sp. nov. 



A single specimen from Upper Assam in the Museum collection 

 (Reg. No. --Tw), broken and incomplete, but striking and character- 

 istic. I refer it tentatively to Eremochrysa of Banks, and with it 

 McLachlan's New Zealand species Chrysopa opposita. 



Length of body about 10 mm., of antennae about 12 mm. 

 Expanse of wings 25 mm. The coloration is wholly obscure save in 

 the wings, which are beautifully marked, and are quite sufficient 

 for the recognition of the species. The membrane of the wings 

 is hyaline, and the cross-veins are all tinged with golden brown, 

 strongly on the basal third of both wings, and all about the 

 entire wing margins, weakly and diffusely and confluently over the 

 wing disc. The brown on the base of the radial sector and about 

 the stigma amounts to diffuse spots of distinctly darker colour. 



Ancylopteryx tesselatus, sp. nov. 



Four specimens in the Museum collection, two from Upper 

 Assam (Reg. Nos. 'V^^ and 'V*') and two from Sibsagar, Assam 

 (5. E. Peal) (Reg. No. m^). 



Length to wing tips 15 mm., expanse of wings 28 mm. 

 Antennae about as long as the fore wings. Head, including 

 antennae, and prothorax pale yellow. Prothorax one half longer 

 than wide, legs yellow, the tips of the tarsi somewhat darker. 

 Wings hyaline and veins white. There are pale cloud-like brown 

 spots at the stigma, at the hinder end of th? inner gradate series 

 of cross-veins and on the tips of the cubital vein where these reach 

 the hind margin. And there are paler more diaphanous and more 

 confluent clouds on three or four of the cross-veins at the rear of 

 the stigma (at the front of the radial vein), on the base of the 

 radial sector and on the anterior gradates, and in alternate spaces 

 along the hind margin of the fore wing. Hind wing similarly 

 marked, but less distinctly, only the basal spot being at all clear. 



Ancylopteryx candidus, Fabr. — One specimen from Upper 

 Assam (Reg. No. -' V"). 



HEMEROBIID/F:. 



Two indigenous genera, Hyposmylus and Berotha, and two 

 wide-spread ones, Hemerohius and Drepa)iopteryx^ are not repre- 

 sented in the collection; the genus Osmylus is represented by two of
