DREPANA. By Dr. E. Strand. 



parvula. D. parvula Leech (= muscula Stgr.) (48 d). Forewing mouse-grey, with three oblique dark transverse 



lines not reaching the costal margin, at the apex of the cell two round white spots and at the apex of the wing 

 a comma shaped, slightly curved, longituduial streak. Hindwing like the forewing, but slightly lighter in the 

 basal area, with small obsolete median spot. (J 25 mm. — Amur, North and Central China. 

 fenestrala. D. fenestrata Leech (48 b). Forewing greyish brown suffused with violet, with two blackish antemedian 



lines and an oblique double line from the apex to the liind margin, a small vitreous spot in the centre and 

 8 similar ones at the apex of the cell. Hindwing in the basal area like the forewing, in the distal area rusty 

 red, with a double median line. 26 to 30 mm. — Western China; in May. 

 palleolus. D. palleolus Motsch. Colouring and size as in D. lacertinarin, but without central transverse bands. 



Ground-colour pale yellowish, forewing above Avith dark transverse bands in the marginal area, hindwing 

 Avith abbreviated dark transverse band in dorsal area. Below the wings are unicolorous. Legs brownish yellow. 

 Eyes black. ,,Exp. al. 11. 1" (accordmg to Motschoulsky). — Japan, on the Main Island and Hokkaido. 

 argenieola. D. argetlteola Moore (30 f). Head reddish yellow, body otherwise light brow^lish yellow, wings about 



the same in colour. Forewing with traces of an antemedian Ime, a large dark discocellular spot, a brown double 

 line from close to the apex to the inner margin beyond the centre, and a row of dark submarginal dots; silvery 

 blue scales here and there. Hindwing with a straight median transverse double luie not reaching the costal 

 bracteata. margin, a row of postmedian dark dots, and silvery scales along the line and at the margin. — bracteata Hamps., 

 from Ci'yion, probably occurring elsewhere as an aberration, is much darker, the discocellular spot of the fore- 

 wing is separated into 3 spots and tliere are more silvery scales. — In the Berlin Museum there are (^(^ from 

 Japan (Yokohama and Nikko) which, beside the nearly whitish yellow colour of their wangs, are distinguished 

 simpH- by the entire absence of the discocellular spot (ab. simplificaria ab. nov.). — patrana Moore (30 f), which seems 

 ficaria. ^^ occur at Darjeeling as a local variety (there are specimens from the former coll. Atkinson before me), 

 is darker on the forewing and in the dorsal area of the hindwing than the main form (unfortunately I have no 

 specimens for comparison from the typical locality of the latter, Java), being sometimes nearly luiiformly 

 brown, but the yellow transverse band and black discocellular spot contrast with the ground; beneath with 

 a dark transverse line on both wings. (J 32 to 38 mm. Tliis form probably occurs as an aberration together 

 with the main form. (J 30 to 45, $ 50 mm. — ■ Widely distributed in India, also in Java, and likewise in Japan, 

 Central and West China. On the wing in July and August. — D. biocularis Moore, placed here by Hampson 

 as a synonym, the type of which is before me, is doubtless a distinct species. 

 grisearia. D. grisearia Stgr. (nee Leech) (48 d). Yellowish grey with two darker transverse lines on both wings, 



not quite reaching the costal margin, on the forewing the one begins somewhat beyond one-thu-d of the inner 

 margin and runs to nearly the middle of the costal margin, the other is very slightly curved and extends 

 from about four-fiths of the inner margin to shortly before the apex of the wing. The lines of the hindwing 

 are parallel and end far below the costal margin. 23 mm. — Amur. Flies at the begriming of Jime. 

 innotata. D. innotata Hamps. Head, thorax and abdomen white. Wings hyaline, with a few scattered white 



scales and entirely without markings. $ 36 mm. — Kulu (Kashmir). 

 bidens. D. bidens Leech (48 c). Margin of the pui-])le-black forewing deeply concave below the apex and less 



deeply so before the inner margin, with a brownish edge, and a line and a cloud of the ground-colour and 

 a broad whitish band. Hindwing lighter than forewing and without whitish submargmal band. Underside 

 light ochreous brown with dark grey discal area. 30 mm. — On the wing in July, in Central China. 

 Tujahui. D.( ? ?) rufulus Motsch. Size of D. lacertinaria, but narrower. Reddish brown-yellow; forewing above 



and below distally with a light band-like marking; hindwing above and below pale reddish at the base; legs 

 red with brownish yellow tarsi. Eyes black. ,,Ex]3. al. 121; i" (according to Motschoulsky). — Whether a 

 species of Drepnna or even a Drepanid ? 

 undulifera. D. undulifera Hamps., from Tibet, the c^" of which is known from Yatung, is whitish, entirely suffused 



with light rust-colour. Head dark rusty yellow. Forewing above and beyond the centre with rusty yellow 

 zigzag lines, which are sharply angulate below the costa, then oblique; dark spots at the angle of the cell. Hind- 

 wing with slight traces of yellow; beyond the middle a narrow line from the submedian fold to the inner margin. 

 32 mm. 

 specularia. D. specularia Walk. (30 f). Reddish brown, forewing with traces of two antemedian and two postme- 



dian wavy lines, a light spot in the cell and two below the base of vein 2, a large light subbyaline smear in 

 and around the apex of the cell, the veins traversing the smear dark. A similar semihyaline smear in the hind- 

 wing, as well as traces of two antemedian, two postmedian and a submarginal wavy line. 46 mm. — It is at 

 least doubtful whether this species belongs to the Palearctic Region. Swinhoe certainly records the type 

 as fi-oni „North-India" in his Catalogue (1892), but Walker himself writes „North-Hindustan", and other authors 

 (Butler, Moore, Cotes and Swinhoe) say Darjeeling, or (Hampson) Sikkim. 



muscutaria. D. muscularia Walk. (30 f). ^ dark purple-grey, vertex reddish yellow. Forewing with reddish yellow 



costa, antemedian, postmedian and submarginal dark wavy lines, the posterior half of the marginal area occu-
