1890.] NEW MOTHS FROM INDIA. 381 



the cell, the second and third from a point considerably beyond it. 

 The vein dividing the cell, as shown in the Plate, differs from Mr. 

 Moore's drawing, which does not, as in the specimen figured and in 

 A, moorei, fork near the end of the cell. 



It will be seen that in both my new species the venation differs 

 in the fore wing, showing that in this as in other genera of Chalcosiidse 

 venation cannot be considered as a good generic character. 



This species was taken by Col. Lang in Gurhwal, North-west 

 Himalayas, where it is found in July flying heavily by day among 

 high trees of Pavia indica. 



In 1887 Dr. Staudinger described yf/. ne/ry/«na (sic) in Romanoff's 

 Memoires, vol. iii. p. 192, figuring the only specimen received under 

 the name of Chalcosia palcearctica (Stgr. I. c. t. x. fig. 3, 2 ) ; taken 

 on the Ussuri river, N.E. Asia, by Dorries. 



I have examined this specimen, which is a much paler insect than 

 A. nelcinna, and has the prothorax and tegulse black, with a yellow 

 collar, which is not visible in A. nelcinna, the breast also is yellow ; 

 the abdomen has a black dorsal stripe marked with narrow yellow 

 bands and four rows of spots, two of them lateral and two ventral. 

 The venation also differs in the branches of the subcostal being all 

 emitted beyond the cell. This species must therefore stand as 

 Atossa palcearctica, Stgr. 



Mr. Leech in 'Entomologist,' vol. xxiii. March 1890, describes 

 A. nelcymna (sic), var. chinensis, as follows : — 



" $ . In this form the neuration is broadly bordered with blackish ; 

 the outer third of all the wings is much suffused with the same colour 

 and sprinkled with greenish-grey scales. 



" Expanse '79 mm. 



" I received one female taken at Changyang (Central China) in June 

 by Mr. Pratt." 



Mr. Leech having kindly lent me this specimen to examine, I have 

 compared it with Mr. Moore's figure, and should say that it as well 

 as a male, obtained in 1889 also by Mr. Pratt at Washan, in the 

 province of Szechuen, and now figured (Plate XXXIV. fig. I), is 

 apparently not separable from A. nelcinna even as a variety, Mr. 

 Leech's comparison having evidently been made with A. palcearctica, 

 which I have shown to be distinct. They agree in their venation, 

 size, and colour, except that they have not so much of the yellow tint 

 as Moore's figure shows. The female has the hind wing rounder 

 than the male, but not so round as in A. paltearctica. 



A third specinien, S , also taken by Mr. Pratt at Huang Machung 

 near Ta-tsien-lo in West Szechuen, has a decided yellow tint on 

 both wings and surfaces, and much less of the dark marking below. 

 It agrees in venation with the other two. 



In neither of these males is the abdomen banded above ; in the 

 female it is inconspicuously so. The thorax in all is black, but in 

 the last-mentioned specimen is a yellow spot on each side of the 

 prothorax. If this is found to be constant and not present in any 

 specimens o( A. nelcinna, as I suspect to be the case, it may belong 

 to a distinct species, for which I would suggest the name A. leechii.
