 red, with no black spots or only indistinct ones above. cJ 56 mm. $ with whitish hindwing and yellow 

 abdomen; 88 mm. — superans Walk. Ground-colour of fore wing pure white, abdomen of rj above ^v^th distinct superan.<t. 

 black spots. ? with, whitish abdomen, smaller than true concolor (65 mm). — In carnecolor Moore both camecolor. 

 sexes are said to have a yellow abdomen and whitish hindwing with the indication of a sublimbal band; 

 markings of forewng narrower and less distinct than in true concolor. Himalayas. — micans Fekl. has white niicans. 

 ground-colour above on the wings and body, with slight yellowish tinge, on the anterior half of the abdomen 

 three or four, on the mesonotum one black round spot, but without the black longitudinal stripe on the 

 thorax of tnie concolor. Hind^ving with narrow grejdsh submarginal band and transverse stripe at the 

 costal margin. ? 70 mm. India, also in the Northern Himalayas. 



L. lucescens Btitl. ^ is allied to L. ascetria Hbn., but larger, the spots in the basal area replaced lucescens. 

 by a single zigzag line ; the line wliich crosses the cell is almost twice as far from the two connected dis- 

 cal lines, and the latter are less incvirved towards the base ; hindwing light glossy grejash brown-yellow instead 

 of yellowish white, as well as without distinct submarginal wavy hne, but the mai-gin is broadly gi'ey. 

 Discocellular spots grey. Expanse 45 mm. — Japan.

 to the Eastern Himalayas and have not yet been recorded from our area*). But in Palearctic Kashmir 

 occurs the form nigra Moore (20 f). All these forms are recognisable by the broad black margin of the hind- nigra. 

 wing, which sometimes, when confluent with the dull greyish basal area, occupies the greater part of the 

 wing, nigra differs from pusilla in the brownish ground-colour of the forewing and the entirely black hind- 

 wing, the head and thorax are moreover spotted mth ochreous and the abdomen is ochreous with black 

 transverse lines, lateral spots and anal tuft. $, forewing with broad deep black confluent bands, with white 

 interspaces. 



L. moesta Swinh. (J & $, palpi and antemiae browii; head, thorax and forewing dark grey; on the moesfa. 

 forewing two darker grey transverse lines, viz., one antemedian angled outwards above the centre and 

 crenate, the other discal parallel A\-ith the outer margin, not far distant from the latter and slightly dentate. 

 At the apex of the cell a gi'ey halfmoon-shaped spot. These markings all very indistinct. Abdomen and 

 hinch\ang lighter grey, suffused with reddish, withoiit markings. Underside uniformly light grey without mark- 

 ings. J 38, 9 43 mm. — Kashmir (Kangra), Kasaoli. 



19. Genus: Ociieria Hbn. 



Closely allied to the preceding genus, bat the antennae of the (^(J mostly rather longer, veins 4 and 5 

 of both wings and the distance between 2 and 3 comparatively shorter ; the wings of the ? more strongly rounded, 

 smaller or very little larger than those of the ^. The moths altogether smaller, the colouring more uniform 

 and the markings simpler. The larvae differ from those of Lymantria by the absence of the brightly coloured 

 knob-like warts. Ocneria is most strongly represented in Europe and especially the MediteiTanean region, while 

 Lymantria inhabits especially the Eastern and South-Eastern countries of the Palearctic Region, and is 

 also widely distributed in the tropics. 



0. detrita Esp. (21 c). S sooty brown black, with black, regularly curved and outwardly finely dentate, post- deirita. 

 median transverse line and black discocellular bar. Abdomen with narrow black transverse bands. ? rather 

 smaller, sooty black-browTi, ^vith dark discocellular spot, but otherwise without markings. (J 34, $ 30 mm. Larva 

 on deciduous trees, blue-grey with white dorsal line, cup-shaped vermilion warts on segments 9 and 10, 

 and otherwise with grey, black and reddish yellow warts; head blue-black; it liibernates when half-grown 

 and pupates in May, the pupa being blackish grey with brown tufts of hair. — Here and there in North Ger- 

 many, Austria and North and Central Hungary, in the lowlands of the Bukovina and as far as Bulgaria, 

 Sarepta, also in South-Eastern France and the South-Eastern Taurus. At the boundaries of its area the 

 moth is often rare, otherwse locally very common; it is on the wing in June and July, and the larve prefers 

 low oak-bushes. 



0. terebinthi Frr. (21 b). Light bluish ashy grey with white dusting, which is most distinct towards terebinihi. 

 the inner margin and base, also filling in the obsolete central lunule. Veins suffused -nith reddish grey. 

 Both transverse stripes rather indistinct, undulate line absent. Hindwing reddish gxey, unicolorous. Ab- 

 domen (9), palpi and femora ((J$) rose-red. $ 34, $ 29 mm. Larva according to some authors not different 

 from detrita. other observers claim to have found differences. Asia Minor, Balkan countries, Armenia. — 

 unicolor Stgr., from Mesopotamia, has the forewing almost unicolorous, without transverse lines. v.nlcolor. 



*] L. heatrix, from .Java, also with broad black margin of the hiiulvviiig, is often considered synonymous with this 

 species, but I believe it to be a different species.
