214 LOEPA: SALASSA. By Dr. K. Jordax. 



o. (ienus; JLoopa Moore. 



Palpi not visible from above, but distinct in a lateral view, as they have the dark colour of the fore 

 tibiae and therefore contrast with the frons. Antennae of o quadripectinate, of $ bipectinate. The spur of 

 fore tibia long, not scaled, obtuse. Forcwuig with rounded apex, and four subcostal branches; upper radial 

 from the cell, cross-vein curved, placed about in the middle of the ocellus, lower median much more proximal 

 than the stalk of the subcostals. Hindwing with distinct though Aveak short iruiermarginal vein (which is 

 absent in the allied genera). 



The species ai'e very similar in markings and colouring. Yellow, sometimes partly brownish red, 

 the collar and the costal margin of the forewLng brown; ocellus more or less deep rust-brown, larger on the 

 forewing than on the hindwing and below smaller and much less distinct than above. Forewmg above with 

 a proximal irregular line, which is sometimes double, and a deeply waved discal line dentate on the veins, further 

 distally there are two parallel lines near together, before the margin a white line or a row of white arcs and 

 below the apex a black spot. The markmgs of the hindwing very similar, but the proximal line more zigzag, 

 and the black subapical spot absent. Paler beneath than above, the markings less distinct. $ like the q, but 

 with shorter and b:oader wmgs. — Larva known of only one species (sikkima Moore). Clothed with rather 

 sparse thin hairs, six rows of warts bearing spines and a long central hair, segments 4 to 10 with a wliite spot 

 behind the stigma, a smaller spot on segment 11; when half and quite full-grown reddish brown shaded with 

 blackish, warts red. A younger .specimen before me almost entirely red; head and pronotum blackish. The 

 youngest stages are said to be black with red warts. Cocoon dense, longitudinal, pointed at both ends. Food- 

 plants: Cissus and Leea. It would be a task well worth undertaking to breed from the eggs the two common 

 Indian species L. kaiinka and sikkima. China. India, Malay Archipelago. 



oberthuri. L. oberthuri Leech (= dogninia So7itfi., dognini Soyith., oberthiiri Leech) (32 d). The first subcostal 



branch of the forewing branches off from the cell. Forewmg above suffused with brownish red from the base 

 to the discal double line, and from the hind margin to the ocellus ; ocelli incurved. — Central China, August. In 

 North-Eastern Assam and Tonkin there occurs a species of a similar colour. 



damiirlis. L. damartis spec. nov. (34 d). A small and very pale species. Light straw-yellow; the proximal line of 



the forewing red, simple, the black subapical spot ovate, above and below it a red streak; hindwing below 

 without a red spot at the apex. The four subcostal branches of the forewing on a common stalk, the first 

 originatin.g more distally than the last. ^ and $ almost alike, the forewuig of the ^ much shoi-ter and rouiader 

 than ui the other species. Most closely allied to \.\\eli\daa,n miranda Moore. — Central and Western China, in the 

 late summer. 



kiiiiiil:a. L. katinka Westw. Venation similar to that of damartis. Upperside chrome-yellow; proximal line of 



forewing double, the black apical spot of the forewing oblique, rounded distally, without a red streak below it; 

 hindwing below with small red spot at the apex. Ocelli with inner black ring or halfring. — ■ West, Central 

 and South-Eastern China, North India; common in the summer, in China especially in July. 



The common Indo-Malayan L. sikkima Moore is not known to me from the Palearctic Region. 



6. Genus : Nalassa Moore. 



Palpi distinctly projecting in a side-view. Antenna of ,^ quadripectinate with the exception of the 

 last one or two segments, the shaft as well as the branches with some spiniform bristles. The segments of the 

 antenna of $ on each side with a short process, which is at most as long as two segments, these processes longer 

 in the distal half of the antennae than in the proximal half, shaft and process with numerous spiniform bristles. 

 Tibiae and tarsi smoothly hairy and scaled, not rough. Spur of fore tibia long; middle tibia with one pair 

 of spurs, hind tibia with two pairs (which is seldom the case in the Saturnids). Tarsal segments with only one 

 pair of spines at the apex on the middle and hind legs, and in the $ also as in most genera with a pair at the 

 apex of the fourth segment of the fore tarsus. Forewing pointed, with a vitreous .spot which is more or less 

 edged with black, but not developed to a real ocellus; with three of four subcostal branches, the first always 

 from the cell, the second short and near the apex of the wing, often absent, the third terminating in the apex 

 of the wing or close below it in the outer margin, first radial from the cell ; transverse vein in both wings angulate 

 or curved, placed at the proximal side of the vitreous spot, foi-ming an acute angle with the second radial in the 

 forewing. Hindwing only above with a ringed ocellus. — Larva not described. The cocoon consists of leaves 

 and bits of wood spun together. Northern India and China. Seven species are known as yet. 



thespi.t. S. thespis Leech (34b). S rusty red; forewuig with a black Ime in the basal fourth, which, in contra- 



distinction to S. lola Westw., is not edged with greyish white, vitreous spot triangular, on the disc a blackish 

 line, in which stands a row of small vitreous spots, more distally a broad blackish band. Hindwing before 

 and beyond the cejitre respectively with a black band, the bands united anteriorly to form a regular curve
