and less distinctly on internal veins; a second roundish spot 

 beneath middle of costa; cilia blackish. 



This species closely resembles Thyrassia suhcordata, Wlk., 

 from India, but vein 10 of forewings is free. Both genera 

 will be found characterised in Hampson's "Moth of India," 

 vol. i., p. 238. Possibly they may eventually be amalgamated. 

 In the present species veins 8 and 9 of forewings are variable, 

 being either separate or short-stalked. 



Not only is the shape, pattern, and coloration of the fore 

 and hind wings that of a Syntomid, but the neuration of the 

 hindwings is very deceptive at first sight. The distal part 

 of vein 8 is wanting, but the proximal part (costal vein) is 

 well marked. The^subcostal vein is weak, and may be over- 

 looked, so that at first it may appear that the costal vein is 

 altogether wanting. More careful examination shows that 

 the resemblance to the neuration of the Syntomidce is merely 

 superficial and misleading.

 a series received from Mr. F. P. Dodd, who informs me that 

 the larvae are short and thick, whitish, with weak hairs, and 

 feed on a species of Vitis, 



ZEUZEKID^. 



Xyleutes nephocosma, n. sip. 



Male, 50 mm.; female, 62 mm. Head grey ; face whitish- 

 grey. Antennas pale ochreous; in female whitish. Thorax 

 grey ; in male with two longitudinally black lines diver- 

 ging posteriorly and some blackish scales on iposterior margin. 

 Abdomen whitish-grey in male; grey in female. Forewings 

 narrow-elongate, costa slightly arched, more strongly in female, 

 apex round-pointed, hindmargin very oblique, rounded be- 

 neath ; whitish-grey ; mottled and blotched with darker grey, 

 which forms three squarish blotches near base, beneath costa 

 at two-fifths, and above inner-margin beyond middle ; and an 

 elongate shade before and parallel to upper half of hind 

 margin ; a series of dark fuscous dots on costa ; a series of 

 short transverse dark fuscous strigulae from inner-margin, some- 

 times united by a fine irregular longitudinal line ; cilia whitish, 

 barred with fuscous on veins. Hindwings elongate, hind- 

 margin scarcely rounded, sinuate before anal angle ; whitish ; 

 in female grey ; cilia as forewings. 



In my male type there is a bar between veins 7 and 8 of 

 hindwings beyond cell Cnot opposite the cell as in Zeuzera). 

 This is absent in the female.
