B. Asiatic species. 



D. crocea Leech (2:5b). Yellow; forewing slightly suffused with reddish, with a subbasal, a central crocea. 

 and a .■^ubniarginal line purple-brown, the last separated into dots, of which those in cellules 4 and 5 and 

 sometimes 6 are enlarged to form two deep black, shaii^ly marked spots with lighter edges. Discocellular 

 spot small, white, with a narrow dark edge, in the hindwing double. The hindwing with but slight markings, 

 the submarginal line only consisting of dots. Apex of wings strongly curved. 43 to 50 mm. — Japan, China. 



D. rubromarginata Leech (48 b), from West China, has yellow forewing with reddish brown marginal ruhro- 

 area (between the inner margin and vein 6), an antemedian, a postmedian and a submarginal transverse line """'i"""'«- 

 blackish, two blackish spots in the cell, and two at the end of the same, the reddish marginal band with a 

 wavy transverse line of the ground-colour. Hindwing lighter, with traces of transverse markings, and a black 

 spot between veins 2 and 3 as well as between 3 and 4. 33 mm. On the wing in June and July. 



D. grisearipennis }iom. nov. (= grisearia Leech nee St.gr.) (48 c), also from West China, has whitish- grisea- 

 hyaline forewing suffused with brownish, with darker basal spot, antemedian, postmedian and median dark '"^P*'*"**- 

 bands as well as an elongate black spot on the upper discocellular and two nearly round similar ones on the 

 lower discocellular. Hindwing whitish, with five dark transverse lines and bands, and two dark spots at the 

 apex of the cell. 40 mm. Flies in June or July. 



D. manleyi Leech (48 b) is Japanese (Yokohama) and has light ochreous brown forewing with two manhyi. 

 transverse lines, a black spot in the cell and i^urple-brown apex; hindwing pale straw-colour, with four brown 

 lines. Underside also pale straw-colour, with brownish apex and on the forewing with brownish post- 

 median and submarginal lines. 20 to 33 mm. 



D. acuminata Leech (48 b). (^ similar to D. falcataria. Light reddish brown; forewing with two dark acumitiaia. 

 brown discal transverse lines, the first of which runs first to the median vein, then to the inner margin, while 

 the second runs from the costal margin towards the distal margin, but then curves inwards and runs obliquely 

 to the inner margin; there are also a dark submarginal line and two small black discal dots. Hindwing 

 with two dark brown median lines, the first curved, the other straight, as well as with a dark brown wavy 

 submarginal line. Underside whitish, in the marginal area of the forewing brownish, both wings with black 

 discocellular dot and two dark transverse lines, one of which is submarginal. 39 mm. In July. — Central 

 China. 



D. hyalina Moore (48 b). Dirty white, semitransparent. Forewing with two darker wavy antemedian hyalina. 

 lines and two similar postmedian ones; the distal one of the latter is widened towards the inner margin; 

 further, a submarginal and a marginal row of indistinct dots. Hindwing with an antemedian, two postmedian 

 and a submarginal indistinct wavy dark line. 43 mm. — Kashmir, West China. 



D. japonica Moore (30 f). Upper side whitish grey; both wings with two narrow yellow brown-edged japonica. 

 oblique transverse bands, the distal one of which runs from shortly before the apex of the wing to shortly 

 before the middle of the inner margin, the proximal one from the middle of the costa to one-third of the inner 

 margin ; foi'ewing ochreous at the apex and at the costal margin, with very small brown discocelhxlar streak. 

 Costal margin of forewing with two dark spots between the transverse lines. In the marginal area of the same 

 wing sometimes a row of 8 or less black dots (ab. punctifera ab. nov.). Beneath both wings bear a discocel- punctifera. 

 lular dot as well as the distal one of the transverse lines of the upperside. Prothorax, and apex and base 

 of abdomen ochreous; underside light ochi'eous brown. 28 to 38 mm. — Japan (Kiushiu). 



D. vira Moore (30 f). Violet-grey, but abdomen and hindwing yellow. Forewing with an antemedian vira. 

 reddish brown line originating at a dark costal spot, a similar postmedian spot, a white spot at the upper 

 angle and two at the lower angle of the cell, and a reddish brown submarginal line. On the hindwing the two 

 transverse lines are only present in the abdominal area. Underside yellow. 30 mm. — • West China, Sikkim. 



D, scabiosa BiM. (30 f). Upper side brownish or pearly grey; forewing with orange costa, a dark grey scabwsa. 

 submarginal streak, greyish brown fringes and an indistinct discal oblique mark formed of small greyish white 

 spots; hindwing with discocellular mark formed of three similar small spots and two or tluee not easily 

 visible parallel discal greyish lines. Collar golden oi-ange. 32 mm. — Japan, Corea, Amur, Central China. 

 Larvae full-grown in August, on Quercus mongolica, where they rest on the upper side of a leaf the edges of 

 which are slightly drawn together by single threads. Pupa hibernates. Moth from the beginning of June 

 to the end of July. — The figure of this species in 111. Lep. Het. Br. Mus. II, pi. 25, fig. 9, is not good. 



D. flavilinea Leech (48 b). $ smoky grey, suffused with violet, basal line of forewing yellowish and flavilinea. 

 indistuict, median line yellow, originating at the yellowish apex, and near the latter merging together with the 

 likewise yellowish submarginal line ; these lines are all continued transversely over the hindwing ; apex of fore- 

 wing produced and obliquely pointed; a small white discal spot present. Underside light ochreous brown. 

 Discal area of both wings greyish and transversely crossed by a faint line; forewing with a small white discal 

 spot; 32 mm. In July. — Central China.
