ACIDALIA. By L. B. Prout. 75 



faint, nearer the distal margin and more regular, followed by a series of blackish fuscous spots, somewhat 

 variable in development, but those on each side of the second submedian vein comparatively large, nearly 

 or quite comfluent, those on each side of the first median also well developed, but well separate. Discal 

 spot well developed and black. Hindwing similarly marked, the discal spot a little larger than on forewing. 

 Under surface considerably paler, quite weakly marked, but with small cell-spots and some traces of the 

 dark distal markings remainmg. Antennal ciliation in the cj moderately long, hindtibia not extremely thicken- 

 ed, tarsus not much shortened. — elyra Swinh., of which I have only seen a single specimen, is without elyra. 

 doubt merely an aberration, differing solely in having a much deeper ochreous ground-colour. Discovered 

 at Rajaori (Kashmir) by Leech in September; all the known specimens are from Kashmir, May and Sep- 

 tember, at 2000 m elevation and upward. 



A. sedatariaLeecA (7c). Systematic position somewhat uncertain, perhaps nearer to the subpunctaria- sedaiaria. 

 group, notwithstanding that the hindwing has the distal margin elbowed in the middle and that both wings 

 are narrower than is characteristic of that group. In any case a very distinct species; its very glossy, pure 

 white wings distinguish it abundantly from all the rest of the angle-winged species. The lines are brownish 

 grey, not very strong (sometimes quite faint), bent near costa, then rather straight or a little sinuous (in the 

 only $ known to me more irregular); usually only 3 are present on the forewing and two on the hind- 

 wing. Cell-spots wanting. Forewing beneath infuscated except m distal area; hindwing beneath white, with a 

 single (outer) line. (J antenna with long fascicles of cilia, hindtibia rather short and thickened, the tarsus 

 nearly as long as the tibia. Western China: Ta-chien-lu, Chia-ting-fu and Pu-tsu-fong, occurring in June. 



A. emtna sp. nov. Very similar to A. hanna Butl. in colour and markings, differing as follows: Rather emma. 

 larger, hindwing only very slightly (in the <^ almost inappreciably) bent at the extremity of the third radial; 

 postmedian line of forewing slightly further from distal margin and with teeth (produced by blackish 

 spots at its distal edge) slightly stronger ; this line on both wings markedly incurved between the radials ; under- 

 side of forewing with postmedian line bending proximad at its costal end; underside of hindwing with the 

 true postmedian line obsolete, a distinct fine outer line occup3dng the position of the proximal dark shading 

 of the subterminal line of the upper surface; ^ hindtibia more strongly thickened, tarsus scarcely one-third 

 of its length. Chungking, Szechuan, 18 September 1909 (type, ^) and 22 June 1909 ($), Barry. A ^ 

 specimen of hanna was taken by Mr. Barry on the some day as the latter. 



A. hanna Btlr. (3 m). Ground-colour about as in the paler forms of the wellknown A. imitaria, hanna. 

 varying between pale reddish ochreous and more whitish; the markings, on the other hand, more nearly 

 as in emutaria. Forewing with first line very faint or obsolete, bent near costal margin, thence running 

 nearly parallel with median shade; median shade rather broad, rather oblique, but reaching the costal 

 margin proximally to the postmedian line or becoming obsolete without touching that line; postmedian 

 very slender, rather weakly expressed, but punctuated with black dots on the veins, its course very slightly 

 oblique and consisting of a series of very feeble proximal curves between the veins; subterminal pale shade 

 marked by weak or very weak dark shading proximally and distally; cell-spot small but black; distal margin 

 with a very fine line interrupted at the vein-ends and often thickened into dots midway between. Hind- 

 wing with the median shade passing close on the proximal side of the cell-spot, postmedian line slightly 

 outcurved, but not sufficiently to run parallel to the distal margin, which is distinctly angled in the middle. 

 Under surface similarly marked, but the entire basal part of the forewing more or less suffused with greyish, 

 the hindwing whiter than above, with the postmedian line and sometimes the median well expressed. Our 

 figure is not very characteristic, in that it lacks the black discal dot of the forewing and the angle in the 

 margin of the hindwing. The average size is rather smaller than in that example. ^ antennal ciliation 

 of only moderate length, hindtibia not extremely thickened, the tarsus about one-half its length. Japan: Yoko- 

 hama, etc.; Korea: Fusan; Szechuan: Chungking in June. 



A. emutaria Hbn. {= subroseata Haw.) (41). Easy to distinguish by its whitish ground-colour, with emutaria. 

 slight or rather strong pink flush. First line of forewing faint, placed nearly as in the preceding species, but 

 almost always bearing conspicuous blacker spots on the median and submedian veins. Postmedian line of 

 both wings bent near the costa, otherwise remarkably straight; that of the forewing usually and that of the 

 hindwing often marked only by the conspicuous black vein-dots. Distal marginal line grey, very faint, more 

 or less interrupted, the dots midway between the veins extremely minute. The median shade of the fore- 

 wing follows a different course from that of the preceding species, being more oblique, meeting the postmedian 

 hne at about the first radial and here disappearing. Forewing beneath somewhat suffused with grey, both 

 wings with cellspot and postmedian vein-dots present, the latter usually becoming nearly obsolete towards 

 the abdominal margin of the hindwing. cJ antenna with strong fascicles of cilia, hindtibia rather short, tarsus
