DASYCHIRA. By M. Gaede. 
i coreana. D. coreana Mats. Somewhat similar to pseudabietis Btlr. (Vol. 2, p. 113, pi. 19 h). Forewings grey 
with a slight suffusion of olive, basal 3rd brownish. The subbasal and inner lines are double and black. Above 
the median nervure the latter is sharply angulated and has a white outer edge at costa. A lunule with black 
outline on black disco-cellular. The outer line is fainter, parallel to outer margin, being only curved below 
median nervure and forming a point below submedian nervure. The black submarginal line is interrupted. 
Inside of same there is a white subterminal line touching a few brown spots between veins 2 and 4. Hindwings 
grey with lunule and a straight dark outer line. 40 mm. Corea. 
^ hvra ' D. hirayamae Mats. Similar to horsfieldi Sound. (Vol. 10, p. 292, pi. 38 c). Forewings dark grey. 
yamn ' whitish at base to the indistinct inner line. The central line is double, its inner branch almost straight, the 
outer one heavily dentate, somewhat more widely separated from one another at inner margin. Lumde spot 
with black edge, sharply angulate and filled with white anteriorly and with pale edge towards base. Outer line 
very dentate. Between same and the somewhat interrupted submarginal line there is an indication of a further 
line, which has a white outward edge at inner margin. Hindwings yellow-brown. Discoidal spot and wide 
submarginal band diffusedly dark brown. £ 48 mm. Tokio. 
suzukii. B. suzukii Mats. Very similar to the previous species, but more compactly built and darker grey. 
Only paler at base and just after the outer line. From the rather primitive illustration it seems to me to have 
a closer resemblance to coreana. Basal line at inner margin of forewings like the latter, closely approaching 
to the inner line. The double inner line not so heavily angulated as in coreana. The outer line single and heavily 
dentate, outwardly with white lunules and beyond same narrowly darker and the rest of wing paler. A sub¬ 
marginal row of spots is indicated. Hindwings yellow-brown with dark lunule and straight wide submarginal 
band. Veins darkened in outer 3rd of wings. $ 45 mm. Kyoto. 
D. modesta Ivy. ( Vol. 2, p. 114, pi. 22 a). Among this species one frequently finds in the Ussuri territory 
immunda. the form immunda Kurd. £ (8 c). Forewings in same are impure brownish grey with indistinct central band. 
. e ff £ - Basal and marginal areas are darker. Hindwings monotonous brown. — $ form effeminata Kard. (8 c) has 
mnmta. forewings as pale an ashy grey as in normal Scarcely a trace of dark central band. About 3 mm from outer 
margin there are 3 black spots. On hindwings the inner %rds are pale grey-brown, the rest is darker.

D. lunulata Btlr. As doubts have been raised regarding the differences between acronycta (Vol. 2, p. 114, 
pi. 19 e) and the typical lunulata , we are giving an illustration of a (8 a) of the latter. 
D. virginea Oberth. (Vol. 2, p. 114, pi. 19 f) is now also known to occur in Japan. — The same applies 
to the indian species nigra Hmps. (Vol. 10, p. 294, pi. 38 e) and strigata Moore (Vol. 10, p. 295, pi. 47 a). 
D. trimacula Scriba (8 a, b) appears to vary somewhat by the greenish grey forewings. At disco- 
cellular there is a large crescent shaped mark with dark edge. The outer line is semi-circular from costa to 
median nervure with 2 large dentations outwards. In marginal area a distinct submarginal line with sharply 
pointed dentations. Hindwings ochreous yellow with a large dark discoidal spot and 3 large spots as marginal 
hand. Thorax and body are greenish brown. $ 55 mm. Besides we are illustrating the which has hitherto not 
been described. Tokio. Ihe illustrations are from the types from the Seitz Collection in the Sexckenberg 
Museum at Frankfurt a. M. 
B. rossii Curtis. I his species was hitherto only known from Labrador and was therefore dealt with in 
Yol. 6, p. 537 and on plate 72 a. As there is a specimen in the Pungeler Collection labelled “Kossogol Lake, 
Mongolia, 1910 , the species must be mentioned here. The outer line on forewings terminates more vertically 
at inner margin than is shown on the illustration on the left on pi. 72 a. On the right the termination should" 
be more oblique outwardly and similarly in specimens from Labrador. — relictus O. B.-H. is also more faintly 
marked on forewings than specimens from Labrador and is thus like the mongolian specimen. The latter and 
also specimens from Labrador have a yellow-grey basal area which contrasts with the marginal area. In relicta 
however the basal area is grey, transparent, the margin dark grey, so that the contrast is less pronounced. 
Konokarcha daisetsurana Mats. (Lasciocampidae) is the same. 
B. groenlandica Horn. (8 c) from Greenland, which as yet is still taken to belong to the palaearctic fauna, 
is alieady dealt with in Y ol. 6, p. 537 and placed in the Genus Byrdia. As there was no illustration, we are 
giving same here. In accordance with its polar origin the species is not very striking. 
B. tesiebrosa Wkr. I have a number of specimens of this species from the British Museum. It was 
already dealt with in Col. 2, p. 116, pi. 22 c. The species appears to be very variable. In one red-brown specimen 
fiom Ta-tsien-lu the central area is distinctly paler; in another specimen from the same locality the ground 
colour is inclined to-be olive-brown, the outer line edged with white on both sides in its anterior portion. One 
specimen each from East 1 hibet and Sikkim are very dark, only the outer line is still discernible and the heavy 
black cuneiform marks at subterminal line. A specimen from Arizan (Formosa) is even darker still. 
. sem C ^ semicirculosa sp. n. is close to magnolia Swh. (Vol. 10, p. 294, pi. 38 c) and is just as dark as same. 
The somewhat dentate inner line extends almost vertically. The outer line is fine and clearly marked. It extends 
vertically from costa to cell and to inner margin, where it is sharply and widely angulated, from lower angle 
of cell approximately parallel to outer margin and dentate to inner margin. It is edged with white scales on 
both sides.
