submarginal band of spots being deep black. It corresponds about to ab. externo-fasciata of pini. — dolosa dolosa. 

 Bull, is closely allied to pini, larger and darker. The inner band of the forewing grey, with a black band at the 

 apex of the cell, the middle of the wing between the bands dark reddish brown, the outer band whitish, its 

 black margin of spots very indistinct. Hindwing dull dark brown, costal and distal margins greyish. Japan.

 wing and marginal area darker. The wliite discal band prominent, the outer band with a sharp white inner 

 edge. Hindwing brown with lighter costal margin. Japan. — The last three insects were formerly treated 

 as distinct species, but they are probably only forms of the very variable segregatus, perhaps one or the other 

 belonging to the likewise closely allied superans. 



D. punctata Walk. (28 d). A rather small dull brown species with whitish discal spot in the forewnng, punclnta. 

 the transverse bands somewhat hghter than the ground-colour, yellowish brown with a dark edge. North 

 China., also Hongkong. 



D. remota Walk. A light coloured pale greyish brown species with whitish antennae and three slightly remoia. 

 wavy brownish yellow bands on the forewing, the outer ones still more diffuse than the two inner ones. Hind- 

 wing uiiicolorous with scarcely a trace of bands. North China, Shanghai. Probably only a form of the preceding.

 the bands are distinct. — excelsa Stgr.. from Amurland, Ussuri and Corea, is very like the Japanese excellens; exceUa. 

 the cj, as in excellens, has the disc bright ochreous, base and margin of the forewing and the hindwing are dark

 widely dentate row of black marginal spots on the forewing. A dark aberration of the species also occurs frequently, 

 ab. obscura Stgr.. which is smoke-grey or blackish grey (cf. 28 f; the figure belongs more nearly to tliis form obscura. 

 than to true bufo). In Spia and Palestine, as well as in the neighbouring districts of Asia Minor. 



19. Genus: Pacliypasa Walk. 



Antenna of (J in basal half with extraorcUnary long pectinations, these cpickly reduced in length beyond 

 the middle and then fairly short to the apex ; in the Ijasal half the posterior pectinations are considerably longer 

 than the anterior ones. Antenna of $ with short pectinations from the base. Palpi porrect, extending slightly 

 beyond the frons, very densely scaled, \vith short and stumpy but cbstinct end-segment. Eyes naked. Frons 

 smooth with dense hair directed forward. Body covered wdth dense long hair, abdomen very long, extending 

 considerably beyond the anal angle of the hindwing in the (^ by almost half its length. Femora and tibiae 

 clothed with long hair, middle and hind tibiae with short end-spurs (otes) or without spurs (lineosa); tarsi 

 smoothly scaled. Forewing elongate, almost regularly lanceolate, with rounded apex, distal and inner margins 

 evenly curved and considerably more so than the costal margin, which is fairly straight in the basal half. Vein 

 2 near the base, 3 close before the apex of the cell, 4 and 5 stalked, 7 and 8 originating one after the other 

 from 6, 9 and 10 on a long stalk emitted close before the upper angle of the cell; 2 to 9 into the distal margin, 10 into 

 the apex. In the hindwing veins 2 and 3 close to the lower angle of the cell, from which originate 4 and 5 

 on a common stalk, 7 originates clo.se to the base, 8 free at the base, then approximated to 7, and touching 

 it at one point or connected with it by a short transverse vein; the accessory cell thus formed is moderately 

 large, narrow and pointed. Accessory veins absent or indistinct in otus, while lineosa possesses three cbstinct 

 accessory veins. Cell closed in both wings, very short and narrow. — Larva somewhat flattened with strongly 

 developed lateral warts on all the segments, these being especially long and resembhng legs on the thoracical 

 segments. Beside the short bristly dorsal and long thin lateral hair the body is also clothed with rather broad 

 large lanceolate scabs, which are especially prominent in the middle of the back, but occur also on the lateral 

 warts between the long hair. Ventro-lateral stripes of hair absent. Segments 2 and 3 with a dorsal, transverse, 

 much raised and brightly coloured swelling, occupjing nearly the entire breadth of the back and bearing a trans- 

 verse incision opening and closing in the live specimen. Segment 1 1 with a broad flat hump, or all segments 

 with two warts, wliich are especially well developed on segment 11. Pupa hairy, mth stumpy anal end, in a
