DIPLODESMA. By L. B. Prout.

Ch„ chlorissodes Prout (131) is of a duller or darker green, not white strigulated, the hindwing still chlorisso- 
more perfectly rounded and with its abdominal margin less elongate; but above all different in being the only 
Chlorissa with the <$ antenna pectinate, so that it should, strictly speaking, be transferred to the North 
American genus Ghlorochlamys. Tonkin, Hainan, Hong Kong (type) and Formosa. 
78. Genus: lliplodesiiia Warr. 
Another offshoot of Hemithea or Clilorissa. Antenna and (generally) leg-structure as in them. Ab¬ 
domen not crested (except, slightly, in Section A). More specialized in that the 1st subcostal is stalked with 
the others and runs into the costal, and there are in some cases other modifications of the subcostal system. 
Moreover the $ of one species ( subexpressa ) has — like the African Neromia — lost the proximal spurs of 
the hindtibia. A small genus, almost entirely Indo-Australian. 
A. Section. Forewing with 2nd subcostal free or anastomosing slightly. 
D. pudentifimbria Prout (13 1). Paler green than mundaria (Vol. 4, pi. 2e), the fringes still paler and jmdentifim- 
with a characteristic pinkish flush. Terminal line weak or vestigial. Abdomen above, except at base, dull brm. 
reddish mixed with white. Assam (type), Perak and Borneo; also perhaps in S. India. 
B. mundaria Leech (Vol. 4, pi. 2 e) is possibly a form of ussuriaria, from which it differs chiefly in mundaria. 
having the lines straighter. See further Vol. 4, p. 24. Described from West China, but now known also from 
North India and Formosa. 
D. ussuriaria Brem. (= eluta Wileman). (Vol. 4, pi. 2 d). On the former misidentification of this ussuriaria. 
species see under Hemithea marina , p. 115. The true ussuriaria , described from East Siberia, is chiefly 
Palaearctic, but occurs in several parts of China, including Ningpo and Szechwan. 
B. Section. Forewing with 2nd subcostal running into costal (Diplodesma). 
D. planata Prout (13 1). This species seems to furnish a link between Sections A and B, as the be- planata. 
longs here while the $, so far as known, conserves the venation of the ussuriaria group. Superficially scarcely 
distinguishable from some rather large mundaria with very weak antemedian line, the line of the hindwing 
still less bent. The name-typical form, from N. W. India, has no dark blotch on the abdomen. — dorsinigrata dorsinig- 
Prout has the costal edge more strongly dotted with black, the cell-marks appreciably darkened, a blackish rata - 
patch on the 3rd and 4th tergites. Khasis. 
D. celataria Walk. (13 1). Rounder-winged than planata, with more sinuous lines, underside with a celataria. 
blackish subterminal band, which shows through as a grey-green shade above. Described from the Sula Islands, 
but widely distributed from Celebes to Fergusson Island, including Teoor and Key. — thalassica Turn., thalassica. 
from Queensland, differs in having elongate blackish cell-marks, stronger on the hindwing. 
C. Section. Forewing with 2nd subcostal wanting (Acrortha Warr.). 
D. caudularia Guen. (= obnupta Swinh., viata Moore, melica Swinh.) (12 k). In shape nearer to cela- caudularia. 
taria than to planata, though slightly intermediate, in the straightish lines and unmarked underside more 
like a small planata. Guenee’s type, which was long misidentified, was from N. India, but the species is 
commoner from Central India to Ceylon; also known from Luzon. 
D. contracta Warr. (131) may possibly be a form of caudularia but has a somewhat narrower hind- contractu. 
wing and shows on the underside a greyish subterminal band, less dark and less complete than that of cela¬ 
taria. Khasis and elsewhere in Assam. 
I). Section. Forewing with 2nd subcostal stalked to beyond 5th, not touching costal (Haloplianes Warr.) 
D. subtusumbrata Fuchs (13 1). Closely like weakly marked celataria, except in the venation. Ter- subtusum- 
minal joint of palpus in the $ perhaps somewhat less elongate. Sumatra (type), Malaya, Borneo and the brata. 
Philippines. 
D. subexpressa Walk. (= olivata Warr.) (131) might have been taken for a form of subtusumbrata subexpres- 
with the band of the underside wanting, but differs in having lost the proximal spurs of the $ hindtibia. sa - 
Postmedian line finely dark-edged proximally. Borneo (type), Malay Peninseda and Banka Island. 
D. xanthochlora Swinh. (13 1) is very distinct in the more sinuate distal margins and in the b r o a d xanthochlo- 
dark bands, as strong above as beneath. The name-typical race, from the Khasis, is at least as large as any ra - 
of the preceding, generally larger. — timida Prout is a dwarf form (15 — 16 mm), or closely allied species, with timida. 
the excisions in the distal margin slightly shallower and the dark markings narrower. Portuguese Timor. 
D. mystica Prout (12 i), founded on a faded $ from S. Celebes, is not a true Diplodesma, as the 1st mystica. 
subcostal is not stalked, though arising very near the end of the cell, and the hindwing is rounded, but
