130 LYMANTRIA. By Dr. E. Strand. 



oberthueri. L. oberthueri Lnic, from Tunis, has the forewing in the o I'gl^t grejish brown-yellow, with a narrow 



dark transverse median band, partly separated into spots, and a similar sublimbal band really only consisting 

 of two transverse lines placed close together and divided by the Hghter longitudinal lines; discocellular black 

 narrowl}' edged -svith white on the outside; costal margin with small indistinct black spots. Hindwng orange- 

 yellow with black sublimbal band, which is broad anteriorly and thin and ]3ointed posteriorly. Fringes 

 yello-nash with very indistinct dark spots. 30 mm. The $ has the fore^ving grejash brown with lighter 

 veins and irregiilarly aiTanged light longitudinal and oblique smears. Hindwing pale reddish grey ^\ith the 

 marginal band broader than in the (J and not so sharply defined. 40 mm. 



ohiuscata. L. obfuscata \Yalk. (22 f) has in the $ reduced wings, which are however better developed than 



in L. incerta Walk. The ^ is greyish brown and resembles L. incerta, the postmedian double lines are 

 more regular, and the liindwing bears a dark central hmule at the apex of the cell, as well as a dark 

 marginal band. $ hght ochreous with darker discocellular vein. Larva light bro^vn, with short dorsal tufts 

 and long lateral brushes and with hght lines along the middle and at both sides. — Kashmir; also distri- 

 buted in India. Our figure is taken from the type in the British Museum. 



obsoleta. L. obsoleta Walk, t^ brown with reddish abdomen. Forewing wiih dark dusting and indistinct ante- 



median and postmedian lines in double halfmoon-shape; discocellular spot black, luniform, no spot in the 

 cell. Hindwing light blackish brown. Head pale rose-colour around the eyes and below, legs and abdomen the 

 same, the latter bearing a dark dorsal stripe. In the $ the abdomen, moreover, has black lateral 

 spots and a dark apex; hindwing reddish in the dorsal area. ^ 42, $ 72 mm. Described from North- 

 albohtnata. India. — albolunata Moore, from Kashmir, is more variegated with black on the forewing, and there are 

 vinacea. white lunules between the postmedian lines. — vinacea Moore is a $-form perhaps only occurring in South 

 India, which is wine-grey with indistinct browTi zigzag lines on tlie forewing, a dark discocellular and mar- 

 Mascara, ginal spots. Hindwing with a narrow brown marginal band. — bhascara Moore has the hindwing rose-colour, 

 with a broad brown marginal band, the forewing being light fawn, densely iiTorated with browii and bearing 

 sobrina. several transverse zigzag lines. Described from North India and Darjiling. — sobrina Moore (according to 

 SwiNHOE a separate species!) is distingiiished by the shai-ply marked transverse lines of the forewing; inner 

 iris, margin of hindwng rose-red. $ with yellowish abdomen. — The form iris form. nov. (20 f), from Central and 

 Southern China, a number of specimens of which from Seitz's collection from Hongkong are before me and 

 to which also the specimens figured belong, are larger in the 9; forewing brown like bark, slightly 

 iridescent bluish with very indistinct greyish markings, the brown gi-ound-colour only appearing as spots and in 

 bands more or less separated into spots; all the gi'ey parts are dusted with large browTi dispersed scales recognis- 

 able with the naked eye. The most distinct of the light markings is a double row of transversely placed 

 luniiles about 7 or 8 mm fi'om the margin, the lunules being convex proximally and their pointed horns being 

 directed marginad. In a lighter median area difficult to distinguish as such, which is about 5 mm broad 

 at the hind margin and almost 10 in the middle, and is separated from the double row of light lunules 

 just described by an almost linear shai-ply zigzag brown band, there is an irregular transverse roAV of 6 or 7 small 

 black spots, of which the one at vein 1 b appears as a longitudinal streak, the one at the discocellular as 

 a transverse bar. The brown antemedian area is chvided into wedge-shaped longitudinal streaks by the 

 lighter veins. In the basal half the light colour predominates, but with a large brown spot in the middle 

 and at the costal margin and one or two black longitudinal streaks in the middle. Underside grey-browii, 

 darkest in the marginal area and at the costal margin, with blackish triangular traiisverse discocellular 

 spot and an almost straight shadow-y light transverse band, partly separated into spots and about 9 mm from 

 the margin in the middle, slightly curved marginad in the hindmarginal area and therefore being here only 

 half as far distant from the margin as in the middle. Dark fringe-spots also visible below. Hindwing 

 light greyish brown, darkest above in the marginal area, but without discocellular spot, below with one, as 

 well as with brownish veins and co.stal and distal marginal areas; in the last a lighter transverse band, 

 which is not however the continuation of the same band on the forewing. Head and thorax brown like the 

 wings, between the eyes a lighter smear, collar red, coxae and base of femora red, legs brown with black 

 bands. End of abdomen brown, above and at the sides reddish (most strongly reddish beyond the centre), 

 and with a greyish median longitudinal stripe above, blackish below, segments partly red at the hindmar- 

 gins. Antennae black, shaft lighter in places. (J smaller, colour of wings as in the 2, but the median area 

 does not bear any black dots except three on the discocellular, which area sometimes confluent. Under- 

 side of both wings lighter, gi'ejish white, only brownish at the costal margin; tlie light transverse band of the 

 ? is only indicated here by the dark hne bounding it at the inner edge; the fringes appear almost without 

 spots below\ Abdomen greyish, lightest below, without a reddish tinge, above with darker median longi- 

 tudinal stripe, laterally a row of deep black spots. Anal tuft gre\ish. — The moths are common in August 

 on tree-trunks, especially on those of older Cassias; the species is distributed over India and Cliina with 

 the exception of the North, and Formosa. 



concolor. L. coticolor Walk. (20 f). ^ whitish yellow or light sulphur yellow, prominently spotted with black 



also on the head and thorax. The black transverse lines of the forewing verj' irregular and more or less inter-
