31. Genus: Herpn Walk. 
Frons projecting, longer than broad. Antenna in the cf with very long pectinations, bushy. First 
hindtarsal joint shorter than the other four together. Cell in both wings posteriorly sloping off at the apex, 
the upper angle strongly projecting; in the forewing the 3. to 5. subcostals stalked, 3. proximal to 5.; in 
the hindwing all the veins from the cell; scaling of the wings peculiar, the scales long or almost hair¬ 
shaped, — Yellow or whitish yellow species with black (or at least in the forewing dark) veins. India 
and China. 
H. venosa Walk. (5c). Pale yellow, the veins brown-black, the scales long, but not hair-shaped: venosa. 
the 2. and 3. radials of the forewing usually from the cell, rarely stalked. — Assam. China produces the 
paler subspecies sinica Obertlu 
H. subhyalina Moore (5c). Whitish yellow, the veins slightly darker; costal margin of the hind- subhyalina. 
wing blackish; the 2. and 3. radials of the forewing usually stalked; scales very narrow, on the under 
surface almost hair-shaped. — Sikkim; Assam. 
H. primulina Elioes. Perhaps only a variety of subhyalina; deeper yellow and the costal margin primulina. 
of the hindwing not blackish; antenna pure black. — Assam: Naga Hills. 
3 other species occur in China: basifiava Oberth., luteola Leech and ochracea Leech (see vol. II, 2d). 
The first of these species probably represents a separate genus: the frons is hairy; in the forewing the 
first two subcostals anastomose with the costa, the other three are stalked together, the 5. branching off 
much more proximally than the 3. 
32. Genus: Psapllis Walk. 
Nearly allied to Eterusia. Frons broad, slightly projecting. In the forewing the 1. and 2. sub- 
costals distally approaching one another, the 2. subcostal from the angle of the cell or stalked with the 
3.—5. subcostals and 1. radial, 2. and 3. radials on a long stalk, 1. median near the angle of the cell, the 
2. median more proximal than the I. subcostal; cell of the hindwing distally somewhat rounded, the lower 
angle more distal than the upper and the 1. radial more so than the 2. subcostal. — Some of these insects 
in both sexes or only in the 2 are strikingly faithful copies of Djsphania species (Geometrids). All the 
species have 5 white spots before the apex of the forewing. 
P. camadeva. cf and 2 different on the upper surface, cf above blue-black, abdomen and hind¬ 
wing purple-blue; frons and sides of the breast whitish, under surface of the abdomen grey-yellow. Fore¬ 
wing beneath blue, distally black, hindwing beneath with yellow cell-spot and yellow stripes between cell 
and hindmargin. In the 2 head and thorax above spotted with white, abdomen yellow, almost white beneath, 
on upperside the base of the segments blue-black; forewing with white basal dot and 2 yellow macular 
bands in the basal half; the spots in the distal half of the wing white; hindwing purple and yellow, a spot 
at the upper angle of the cell whitish: under surface blue and purple, the yellow markings larger than 
above. Malayan. — camadeva Doubl. (2 = semiplena Ii alk. = resumpta Walk. = natunensis Rotlisch.). In camadeva. 
the cf the underside of the forewing is almost entirely blue, that of the hindwing purple-blue. The yellow 
band on the forewing of the 2 is narrow and the spot at the apex of the cell white. Borneo; Natuna 
Islands; Malacca; Singapore; Java (Mus. Oxford). There are only very few specimens known from the 
different localities; perhaps these belong to several local races. — Of celebensis subsp. nov. (5c) 1 only celebensis. 
know 2 cfcf and 1 ?, from North Celebes. The yellow band of the green under surface of the forewing 
is much broader than in the preceding form, the cell-spot is yellow; on the hindwing the yellow area 
reaches to beyond the upper angle of the cell, being joined to the spot placed at the cell-angle; the blue 
gloss of the under surface is reduced in extent and intensity and the yellow area of the forewing reaches 
close to the cell-spot. In the cf the forewing above is dull green; the hindwing above is blue, with the 
exception of the margin, or entirely dull black; beneath the blue is much less extended than in camadeva. 
P. gloriosus. cf not known. ? similar to the preceding species. The blue gloss of the under 
surface and of the hindwing above much more extended and very strong. All the spots white except the 
yellow distal part of the posterior streak of the hindwing. Sumatra; Borneo. — gloriosus Rotlisch. Hind- gloriosus. 
wing above and beneath distally broadly deep purple-blue. West Sumatra; 1 2 in the Tring Museum. — bomeensis. 
borneensis subsp. nov. (5d). Hindwing above and beneath distally only narrowly deep purple-blue. North 
Borneo; 1 2 in the Tring Museum, a second in the British Museum. 
P. albivitta Rothsch. (5d). cf not known, probably as in P. camadeva different from the 2. An albivitta. 
angular stripe on the vertex behind the raised tuft, indications of dots on the thorax, first abdominal 
segment above and the abdomen beneath white; thorax and upperside of the forewing green-black; a band 
on the forewing and the hindwing white, the distal margin of the latter above and beneath and the under¬ 
side of the forewing with blue gloss. — Mt. Gede, Java, 4000 ft.; a second, somewhat different specimen, 
in bad condition, from Lombok, 2—2500 ft., in June; both in the Tring Museum.
