GYMNOCHROMA; CHLOROGENIA; PSILOPEPLA. By Dr. A. Seitz. 
10. Genus: Gynmochroma Hmps. 
Recognizable by the very long, pointed cell of the forewing, from which the 3rd subcostal vein as well 
as the joint footstalk of the 4th and 5th rise; the 1st subcostal vein runs close along the costal, but does not 
anastomose with it. Ground-colour whitish, little marked. Based upon a species from the Khasia Hills. 
fulvipicfa. G. fulvipicta Hmps. (18 k). Forewing white, little marked dark, the apical half tinged oclireous; 
forewing with a slight grey hue, towards the base lighter. Khasia Hills. Type of the genus. 
plagiata. G. plagiata Rothsch. rf: head, antennae and thorax creamy-white; abdomen dirty-white. Forewing 
creamy-white; with irregular bands in the basal half and large irregular spots in the distal half of a yellowish 
brick-brown colour. Hindwings milky-white. Length of forewings: 9 mm. Mambare River, in June. 
11. Genus: Chlorogenia Meyr. 
Forewings broader, the costa not so humped as in the $ of the Gymnochroma ; cell shorter and broader, 
not pointed, but broadly truncated, the 3 rd subcostal vein and the footstalk of the 4th and 5th rise separately. 
cholera to. C. cholerata Meyr. Marking similar to that of Psilopepla margaritacea (18 k), but the butterfly is 
smaller and of a more yellowish colour; the dark dentate lines of the forewing are denser, so that 5 chains of 
spots or dentate lines are distinguishable (instead of 3 as in margaritacea). New Guinea. 
12. Genus: Psilopepla Tmr. 
As to this genus which may be considered as the Indian representative of the palearctic Nudaria mun- 
dana, comp. Vol. II, p. 51. The cell of the forewing is very long, the 1st subcostal vein rises in the middle of 
the cell, the 3rd, 4th and 5th have a joint footstalk. Indo-Australia; 2 species have also been found in the 
palearctic region. 
margarita- P. margaritacea Wkr. (~ margaritaria Wkr.) (18 k). Recognizable by the beautiful mother-of-pearl 
rea ' lustre. Comp. Vol. II, p. 51. — The figure is made according to the type in the British Museum. 
fasciata. P. fasciata Moore (Vol. II, t. 11 b). Larger, better coloured than the preceding; forewings blackish- 
brown, the distal third yellowish-grey, marked white. Further particulars vid. Vol. II, p. 51. — The form 
promelaena. promelaena Hmps. does not occur in the palearctic region and was therefore not described at large in 
Vol. II; it differs from typical fasciata by the yellow being reduced, the postmedian line bent backward 
towards the costa and not connected with the subapical spot; hindwings tinted dark brown. From the Khasia 
Hills. — Some specimens are remarkably pale so that they are without any dark tint. Before the border an 
irregularly dentate line which is inwardly turned round towards the costa to the submedian line. This light 
sordida. form may be denominated: ab. sordida nom. nov. (= ab. 2 Hmps.). 
suffusa. P. suffusa Hmps. (18 k). Marked still brighter white than fasciata, but the wings otherwise uniformly 
suffused with a sooty blackisli-grey, not yellow in the marginal third. Sikkim and Assam. 
fumidisca. P. fumidisca Hmps. (18 k) is still much lighter, the forewings nearly white, little marked, only in the 
disc still more intense smoky-grey shading. Smaller than the preceding. Sikkim and Assam. 
mollis. P. mollis Luc. (13 c) is still smaller than fumidisca , the smoky-grey zig-zag marking in the discal 
area replaced by honey-coloured dentate lines. Brisbane in Queensland. 
discipinida. P. discipuncta Hmps. (18 k) is easily distinguishable from mollis by the marking of the forewing being 
in the costal half honey-coloured, in the proximal half smoky-grey. Bhutan, Assam, and Pulo Laut. 
variegata. P. variegata Rothsch. (J: head and thorax milky-white. Forewings milky-white; a subbasal band, 
an antemedian and 2 postmedian, oblicpie, irregular bands brownish-buff. Hindwings brownish-buff. Length of 
forewings: 7 mm. Cumusi River in New Guinea, in August.
