OLANIS; LEUCOPHLEBIA. By Dr. K. Jordan. 239 



Islands. Three species occur in tlie Palearctic Region, but several others extend to the Southern boundary' 

 of our Region in North- West India. 



C. schauffelbergeri Brem. <£• Grey (= trilineata Roths.) (37 a). Abdomen of ,^ and ? without dorsal schmiffel- 

 line, but segment S of q with olive median spot. Forewing with two blackish green rounded spots in the basal f'en/eri. 

 area, one at the costal margin and the other below the cell, the costal one being the larger; the antemedian 

 double line and the dentate discal lines distinct, the submarginal line posteriorly quite near the margin. The 

 eight abdominal sternite of ,^ is slightly rounded in the middle of the margin, not produced into a process; 

 the harpe ends in an almost straight thin process, which lies along the ventral edge of the clasper, the upper 

 edge of the harpe formed of a dentate ridge wliich is highest distally and whose apex is downcurved. Vaginal 

 orifice of 9 large, before it a triangular central lobe. — Japan (Main and South Islands), North China, certainly 

 also distribued further north- and southwards. 



C. ochracea Butl. (37a). Clayish yellow; ^ and $ without dorsal line, ^ with dorsal spot on segment 8. ochracea. 

 The costal one of the two spots in the basal area of the forewing is much smaller than that below the cell, 

 the antemedian double line of the cell less oblique than in schauffelbergeri and the inner discal line farther 

 from the cell. The distal process of the harpe of S much shorter and broader than in schauffelbergeri and the 

 upper edge of the harpe bears a large tooth proximally, the apical process of the sheath of duct of ,^ is denti- 

 culate in schauffelbergeri, non-dentate and pointed in ochracea. Before the vaginal orifice of the $ a high trans- 

 verse ridge which is deeply incised in the middle. — Distributed from Japan to North India, not rare. 



C. japonica Roths. (37 b). Distinguished from all other species of this genus by the broad subbasal japonica. 

 transverse band on the upper side of the forewing. — Kiu-Shiu and Corea, only a few specimens known. 



12. Genus: Claiiis Hbn. 



Easily distinguished from Oxyambulyx by the spinose tibiae and short end-segment of antennae. The 

 tongue is strongly developed, but at most extends to the base of the abdomen. Forewing entire, with pointed 

 apex. Hind tibia with two pairs of spurs; pulvillus. paronychium and frenulum present. Abdomen above 

 with very numerous spines at the edges and many small weak spines below the scaling on the dorsal surface 

 of the segments. — Larva granulose, with oblique stripes; head in the first stages conical, later on rounded 

 and large; only known of one species. 



Seven species ; distributed from Japan to Ceylon and the Nicobars and eastward to Timor. The mot lis 

 easil}' fade, and freshly caught specimens are much more reddish brown than old ones. 



C. bilineata Walk. (37 c). Forewing beneath with black longitudinal smear below the cell. Upperside bilineata. 

 of middle and hind tibiae white. Hind margin of forewing of (^ as long as the outer margin, in the 9 Icnger. 

 Ground-colour reddish brown, shaded with grey; forewhig with two ante- and three postmedian transverse 

 lines; at the apex of the cell a pale streak which bounds a large pale costal area; genitalia of both sexes very 

 different from those of all the other species. — Japan and Corea to North India; the most common species 

 of Glanis of these districts. 



C. undulosa Moore (37 b). Usually larger than bilineata, darker, the black markings more sharply mululoaa. 

 developed, the wings more elongate, the black basal area of the hindwing larger. Upper side of middle tibiae 

 black, not white as in bilineata; spurs of tibiae longer. The anal tergite of ,^ incised in the middle of the apex 

 and the two halves thus formed are downcurved. The eight abdominal tergite of the $, which is deeply incised 

 and long in bilineata, is very short in nndulosa. and bears but a very shallow sinus. — Distributed from North 

 China to North India. 



In North-West India a third .sjiecies, deucalion Walk., extends to near the Palearctic boundary. 



13. Genus: lieucoplilobin Westw. 



A genus distinguished by its peculiar colouring. All the species more or less pink; forewing with pale 

 yellow stripe from the base to the apex. 



Tongue short and weak. Antennae with short end- segment ; in the ,^ the lateral grooves deep and the 

 segments produced above it into short round teeth or even long pectinations; in the $ the antenna slightly pris- 

 matic, almost entirely without prolonged cilia at the sides. Tibiae spinose; hind tibia with two pairs of spurs, 

 the longer apical one of which is about one-third as long as the first segment of the tarsus ; pulvillus and paro- 

 nychium present, but the lobes of the latter reduced. Forewing entire, with the apex pointed but not jJroduced, 

 outer margin convex, hind angle very strongly rounded, not produced even in the hindwing. — Larva granulose, 

 on each side with two white longitudinal stripes, the upper one of which is broad and the lower indistinct. 

 According to Boisdu\ul on sugar-cane. — Africa and India, distributed northward to North China. So far 

 five species are known.
