not so large as in japonica. On Salix babylonica, also on Wild Pear and Apple, and Walnut. The moth in the 

 autumn, common in North and North- Western India, reaches the Palearctic Region in Kashmir (Swinhoe). 



10. Genus: Jfooris Moore. 



Tongue absent, palpi small, united at the base, of the same colour as and long-haired like the frons. 

 Antennae slightly chitinised, pale, the branches thin ; in the (^ quadripectinate to the apex, the branches of 

 each segment about equally long, only the distal ones of the last three or four segments shortened, the median 

 branches about as long as five segments, the shaft ventrally with broad naked stripe, no sensory cones at the 

 apex of segments, or now and then a small central apical cone. In the $ the shaft of the antenna as in the (J, 

 all segments qiuidripectinate, the proximal branches of the median segments twice as long as the distal ones 

 and as long as 2^4 — 3 segments, the distal branches of the last six segments quite short or only just indicated. 

 Cell of forewing slender, shaped almost exactly like that of the hindwing, median vein not so strongly incurved 

 proximally as in Caligula and Perisomena, three subcostal branches, the common stalk of which is more prox- 

 imal than usual and branches off almost at the same level as the lower median branch, stalk of the two upper 

 radials longer than the cell is broad ; cross-vein of both wings regularly incurved, traversing the proximal part 

 of the large round ocellus. Spur of fore tibia short, not scaled, in tlie i^ one-eighth as long as the tibia, in the 

 $ quite a small lobe. Tarsi spiny below, segment 5 of fore tarsus of $with naked sole; paronychium short, pul- 

 villus pale and small. Like Saturnia in facies. — Larva with similar hair to that of P. caeciqena, according 

 to Statjdinger entirely without warts, not known to me in nature. Cocoon transparent, thin, irregularly reti- 

 culate, meshes small. Pupa with very stumpy rounded cremaster, which, on each side in a rounded groove, 

 bears a tuft of short curved, sharp, stiff bristles. 



The four forms belonging here represent each other geographically, and agree so closely that they 

 are undoubtedly only forms of one species. 



N. huttoni. Varies from brownish grey to dark ochreous. Collar grey. Wings with a simple blackish 

 antemedian line, which has a slight proximal light edge, between it and the base a large grey wedge-shaped 

 spot in the cell of the forewing. On the disc a dark double line which, on both wings, is accompanied outside 

 by a light line and is strongly festooned on the forewing; median area of forewing dusted with blackish, ocel- 

 lus sometimes smaller on the forewing than on the hindwing, edged with black, especially on the hindwing, in- 

 side the same a white curved transverse streak which is not central but is shifted basad. On the underside the 

 ocellus of the forewing is more sharply defined and larger than that of the hindwing. All the forms are Pale- 

 arctic, one entering the Indian Region in North- West India. Larva on Sjjiraea and according to Hutton on 

 Pirus. — huttoni Moore (31 d), from North- West India, is the most unicolorous subspecies ; dark ochreous, the huttoni. 

 lines less distinctly prominent than in the other forms, the black edge of the ocellus of forewing very narrow 

 and almost obsolete distally. Mussoorie. — stolizkana Fldr. (= shahdulla Moore, shahidula Moore, stolizkai sfo&Aana. 

 Moore) (31 c). More greyish, the light discal line nearly white, the black edge of the ocelli mere distinct, and 

 the outer black discal line heavier than in huttoni. Ladak and Yarkand, at an altitude of more than 12 000 ft. 

 — galerope Pilng. (32 a) is very like huftofii, but duller in colour, more reddish brown, the black lines more galerope. 

 distinct, on the underside the white discal line faint or absent, the outer black discal line however usually sharply 

 defined. Budschnurd, Atrek River, Northern Persia. — schencki Stgr. (= schenki Stgr.) (32 a). The most schencki. 

 prominently marked form; bases of abdominal segments blackish; the black edge of the ocelli broader, and 

 the antemedian and discal lines very distinct, disc shaded with grey. Beneath the white outer line sharply 

 defined. Saisan, Alexander Mts. and Ferghana. 



11. Genus: Perisomena Walk. 



Tongue aborted. Palpi very short, united at the base, just as long-haired as the frons, with which they 

 do not contrast. Antennae pale with thin lateral branches, in the ^ each segment with 4 processes of about 

 equal length, in the $ with two, those of the central segments as long as five segments in the (J, scarcely as long 

 as one and a half segments in the $; the cilia of the (J are directed up and down. Wings semitransparent, 

 the scales small and deeply slit; forewing with two subcostal branches, the common stalk of which branches 

 off at almost exactly the same level as the upper median branch, sometimes a third subcostal branch is indic- 

 ated, the two upper radial branches stalked, the first rarely branching off from the cross-vein; cell of both 

 wings closed; the cross-vein almost quite straight, in the centre of the small round ocellus; cell of forewing 

 narrower basally than in Neoris, the costa.1 of hindwing into the costal margin, subcostal nearly straight except 

 for the distinctly downcurved apex, ending in the apical angle. Spur of fore tibia not scaled, obtuse, in the ^ 

 about one-third the length of the tibia, in the 9 reduced to a short lobe hidden beneath the scaling. Tarsi with 

 spines, especially at the apices of the segments, sole of segment 5 of fore tarsus with a spot of small scales. Larva 

 clothed with numerous thin hairs, some of which are as long as a segment; each segment with six small warts, 

 the dorsal warts larger than the lateral ones, all clothed with very long thin hairs; the dorsal and subdorsal
