bent back in the middle, in the (J with the pectinations of the basal half very long, shorter towards the apex, 

 the posterior branches longer than the anterior ones, in the $ the pectinations short and of even length. Palpi 

 upturned, reacliing to upper margin of eyes, densely and smoothly scaled, broader towards the apex. Eyes 

 naked. Frons smooth, densely covered with porrect hairs. Body smoothly and densely hairy, abdomen ex- 

 tending far beyond the anal angle of the hindwin.g. Forevving of .;? rather narrow and slender, broader in the $, 

 costal margin only curved in the outer half, distal and inner mai-gins rather straight, forming an obtuse rounded 

 angle. Hindwing elongate, costal margin quite straight to the tip, distal margin moderately curved. Venation 

 similar to that of Lebeda. but veins 6 and 7 as well as 9 and 10 on longer stalks in the forewing, 8 close beyond 

 the cell from the stalk of 6 and 7 or chrectly from the apex of the cell; vein 10 into the apex, strongly curved 

 at the end. Venation of hindwing as in Lebeda, but veins 4 and 5 on a slightly longer stalk; basal cell with 

 a strongly forked accessory vein at the base and another short simple one beyond the centre. Femora and tibiae 

 with dense long hair, middle aiid hind tibiae ^vith moderately long end-spurs, tarsi smoothly scaled. — Larva 

 flatened, with long lateral hairs. Lateral warts well developed, pediform, especially long and cylindrical on 

 the thoracical segments, conical on the other segments. Ventrolateral stripes of hair absent. Segments 2 

 and 3 with two densely bristly, brightly coloured dorsal belt-like spots, segment 11 with flat hump. Dorsal 

 scales absent. The ty})ical species, P. plagifera Walk., is represented in Amurland by a special form. 



P. plagifera Walk. (30 d). A large species, the $ measuring almost 120 mm. Greyish brown, usually plat/ifera. 

 with a reddish tinge. Forewing with a deej] chocolate brown spot occupying the grater part of the outer half, 

 extending to the margin and to the apex, and only leaving a broad stripe at the outer margin; the inner and 

 costal edges are very sharply defined and are bordered by a narrow black band originating in the middle of 

 the inner margin, running obliquely outward close to the costal margin and then curved backward, running 

 back to the inner margin, where the bounding line is usually narrowly white ; in true plagifera the spot extends 

 to the distal margin and to the apex without a definite edge, and is traversed by a continouous, more or less 

 distinct, black submarginal dentate band ending in a sharp black spot at the hind angle. — In the form from 

 Southern Amurland, femorata Men., the dark spot of the forewing is sharply bounded also distally along the femorala. 

 recurring band, without extending to the margin. — Eggs very large, chalky wliite, deposited at the end of 

 July in clusters of 6 to 12 on the underside of leaves. Larva (according to Graeser) resembling that of Giistr. 

 quercifolia and populifolia, very large in proportion to the moth, on various deciduous trees (Phellodendron 

 amurense, Populus tremula, Quercus mongohca, Corylus heterophylla, Tilia cordata, Syringa amurensis, and 

 Pirus). The young larvae live gregariously usually at the tips of branches. After liibernating they are still 

 found singly on tree-trunks. 



22. Genus: Taragaiiia Moore. 



Most closely allied to Pdchypasa, very similar to tliis genus in the build of body and antenna as well 

 as in the shape of the wings. The branches of the antenna of the ^ become suddenly shorter in the apical half. 

 The rather long porrect palpi are curved downwards at the tip, the end-segment is short, stumpy. Eyes naked. 

 Body as in Pachypasa densely hairy, the patagia usually of a dark and conspiciious colour. Mddle and hind 

 tibiae with very short end-spurs entirely hidden in the hair. Forewing in both sexes elongate, with pointed 

 apex, distal and inner margins evenly curved, hind^v^ng shorter and broader in the J than in the $, with strongly 

 curved or even concave distal margin, the hind angle being rather well defined. In the forewing vein 4 ori- 

 ginates close to the lower angle of the cell, but is distinctly separate from 5, 8 originates from the middle of 

 the long stalk of 6 and 7, the stalk of 9 and 10 long, often considerably longer than the fi-ee ends of the veins. 

 In the liindwing the veins are as in Pachypasa, a distal accessory vein leaves the spindle-shaped basal cell at 

 the base, and often another vaguer one before the apex. Margin entire, with short fringes. Beside the dark 

 discal spot, sometimes indistinct, the forewing usually bears two wliite basal spots and two undulate white 

 transverse lines, between wliich there is a very dark large spot in the <$. The S<S are considerably smaller tlian 

 the $9. — Larva similar to that of Gastropacha, with the dorsal hair short, the lateral hair long and in tufts; 

 the lateral warts are only well developed on the thorax. Segments 2 and 3 with dorsal girdle-shaped spot 

 clothed with black hair, 4 to 1 1 with four dorsal warts each, two large anterior and two smaller posterior ones. 

 Pupa clothed with short hair with the exception of the wing- and leg-cases. — The genus occurs in all the warmer 

 regions of the Old World. The purely Palearctic species are confined to the Mediterranean area and have 

 one representative in Amurland. Also a few Indien species must here be recorded, occurring in that part of the 

 Himalayas which extends into the Palearctic Region. 



T. repanda Hbn. (29 a). Very variable in size, $ up to 80 mm. in expanse. Head and tegulae grey in the repanda 

 (J, patagia deep reddish brown, the rest of the body lighter reddish brown: in the $ the entire body grey, only 

 the patagia rust-coloured with white edges. Forewing brownish grey with sharp white discal spot and irregu- 

 larly dentate white submarginal band, as well as a black discal spot, which is only distinct in the cj, in the middle 

 of the costal margin also a white spot. In the (J, between the discal spot and submarginal band and bounded 

 by the latter, a large dark rust-brown to blackish brown spot. Forewing of $ more or less variegated with
