in the specimen before me. In any case, however, it will represent a good local race. It is of a dark mousegrey 

 colour, almost entirely without the ochreous shade of typical virgulata, while the strong dusting and extreme 

 weakness of the markings would separate it from subsp. parallelaria. Perhaps the most striking characteristic 

 of suhstrigaria is the absence of the discal dots, both above and beneath ; even on the hindwing only the 

 very faintest suggestion of it is discoverable. N. E. Siberia to the Southern Altai. Herz's Witim specimens 

 were captured in July. 



A. plumbearia Leech (5 f) is very distinct in appearance from all the other Palearctic species, though plumbearia. 

 very closely related to the Indian mecysma Swinh. The glossy, dark brown-grey ground-colour and the po- 

 sition and course of the markings show a remarkably close resemblance to Somatina mendicaria Leech, from 

 which it differs essentially in structure, the ^ antenna being moderately ciliated, without pectinations, the 

 $ hindtibia more thickened, with the tarsus shortened (perhaps about one-haLf as long as tibia) and both 

 ssxes easily distinguishable by the neuration. Under surface rather paler, the median and postmedian lines 

 present, the latter the better developed. Only the original pair from Kiushiu are yet known to me. The 

 (J was taken at Satsuma in May, the $ at Nagasaki in June. The sexes appear to be quite alike. 



A. umbelaria Hhn. (= sylvestrata Bhh. nee Hhn. = compararia H.-Sch.) (4 k). White or whitish umbelaria. 

 sparsely sprinkled with blackish; the lines brown, the postmedian sometimes more dusted with blackish. Fore- 

 wing with first line angled in cell, thence oblique, placed rather near the median shade, seldom very 

 sharply expressed, occasionally wanting; median line curved near costa of forewing then nearly parallel 

 with distal margin or very slightly oblique inwards, sometimes rather thick; on hindwing usually crossing 

 the cell-spot or bending round its proximal side; postmedian line parallel with distal margin or very slightly 

 sinuous ; proximal shading of subterminal usually, and distal shading sometimes well developed ; distal margin 

 often with very small black dots or dashes between the veins; base of fringe with small black dots, of varying 

 intensity, opposite the veins. Discal dot nearly always present on the hindwing, though usually minute; 

 often wanting on the forewing, very rarely conspicuous. Except that the (J is a little more strongly dusted, 

 the sexes do not differ above. Beneath the ^ forewing is more or less infuscated, the markings usually well 

 expressed, excepting the inner line, the hindwing nearly as above; the entire under surface of the $, on 

 the contrary, is rather pale, the markings always weak, sometimes nearly obsolete. The distal margin of the 

 hindwing is weakly angled in the middle, but occasionally so weakly as to be scarcely noticeable. (^ antenna 

 with the ciliation of moderate length; hindtibia rather short and thick, tarsus more than one-half as long as 

 tibia. The species is generally recognizable by its large size. Larva very elongate, fawn-colour, with dark 

 dorsal stripe und usually some dark dots beside it. Pupa yellow-brown with rounded dark cremaster. Cen- 

 tral Europe, S. W. France, S. E. Roumania, Tarbagatai and Altai Mountains and S. E. Siberia, flying in 

 June. — szechuanensis subsp. nov. is smaller, especially the $, the hindwing with the distal margin only szechuanen- 

 very slightly bent (in one or two specimens scarcely appreciably) the ^ antennal ciliation slightly stronger, *^" 

 the hindtarsus perhaps relatively a little longer, the discal spots extremely minute or wanting, no terminal 

 dark dots, or at most only one or two extremely small and uadistinct ones anteriorly (a more noticeable series 

 on hindwing beneath) ; .lines mostly indistinct, the postmedian the best defined, placed rather further from the 

 distal margin, showing more tendency to become dentate and sinuous than in typical umbelaria, but rather 

 variable; under surface of (J forewing more strongly and uniformly darkened, the lines therefore less distinct; 

 that of the hindwing usually with inner subterminal line defined. Ta-chien-lu and Chow-pin-sa (5 ^), Moupin 

 (2 $), all from the Leech collection; recorded as umbelaria, without mention of the differences, which may 

 well be of specific value. A form recorded (but not described) from Chan-Si by Alpheraky may prove to be 

 the same. — majoraria Leech (4n, 5 c) is a large race from Japan coloured more like the t3rpe-form, but with majorariai 

 the lines on an average thicker and more ochraceous; terminal dots wanting, discal dots wanting or a very 

 minute one present on hindwing only. Under surface very weakly marked in both sexes. May to the beginning 

 of July. Two very strongly marked $$ show an ochreous-brown spot on the discocellulars. 



A. fumosaria (Bang-Haas in litt.) sp. nov. (3 m) is similar to umbelaria szechuanensis, but has shorter, fumosaria. 

 broader wings, the hindwing with distal margin quite rounded, and is of a slightly less yellowish white, 

 the lines more greyish brown. Thus to some extent intermediate between umbelaria and the purer white 

 group {subpunctaria, etc.). Except in its much whiter colour rather recalls certain forms of ternata Schr., 

 the dusting and the darkening of the extreme costal edge of the forewing about as in that species. Inner line 

 of forewing weak, median line very weak, the three outer lines better expressed, continued on the hindwing. 

 Under surface, at least of the forewing and the costal region of hindwing, even more strongly dusted with 

 smoke-colour than in ternata or in szechuanensis both wings beneath with distinct black discal spot, that 

 of the forewing slightly elongate, that of the hindwing narrowly pale-ringed; postmedian and subterminal 

 dark lines moderately distinct on forewing, the subterminals on hiiadwing also. Antennal shaft moderately
