CHRYSOCRASPEDA. By L. B. Protit.

here very strongly so; but it is interesting to notice that the pectinate Ghrysocraspeda are chiefly Papuan, not 
(as in the case of Ptochophyle) Malaysian. About 40 known species are Indo-Australian, a very few African; 
the one reputed Syrian (see Supp.-Vol. 4, p. 30) is of doubtful origin. 
Ch. gibbosa Warr. (15 g). Easily known by its gibbous-margined forewing and straightish-margined gibbosa. 
hindwing, as well as by its markings. Assam, the unique type a $ from Tezpore. Hampson incorrectly sunk it 
to plumbeofusa Swinh. 
Ch. truncipennis sp. nov. (17 c) is so obviously related to gibbosa that it must be congeneric, notwith- truncipennis 
standing that the type $ has retained a minute areole — whether as a sport or a sexual or specific character 
can only become known when more material is to hand. Forewing slightly more gibbous still; colour very much 
darker, predominantly red-brown though with much the same pale purplish grey suffusions; the acutely angul- 
ated antemedian line much more sharply developed; cell-mark of forewing not ringed with yellow; dark borders 
of both wings narrower. Underside almost unmarked (in gibbosa with central suffusion and curved postmedian 
buff on both wings). Kinabalu. 5 May 1903 (Waterstradt), 1 $ in the British Museum. It wall not surprise 
me if it proves to be a subspecies of gibbosa or a $-form there of. 
Ch. praegriseata Warr. Wing-shape approaches, without quite attaining, that of gibbosa (log). Co- praegriseata 
louring intermediate between this and truncipennis , nearer to the former but without yellow suffusions. Fore¬ 
wing with a pale costal border, broadening at apex to an irregular patch of at least 2 mm extent, cut proximally 
by the excessively oblique,'cinnamon antemedian (which becomes indefinite behind its acute subcostal angle) 
and bounded in its distal part by a curved and irregularly dentate shade of the same cinnamon; a small extension ■ 
of the costal border just outside the antemedian, reaching the minute black cell-dot; dark terminal line slender; 
fringe buff. Hindwing with white-pupilled cinnamon cell-ring, double subbasal line and vague sinuous post¬ 
median; dark terminal shade less broad than in gibbosa. Underside almost as unicolorous as in truncipennis. 
Biagi (type) and Dinawa, British New Guinea, only 2 specimens known to me. 
Ch. flavimacula Prout (17 b). Colours about as in gibbosa, their distribution quite different, with the flavimacula. 
ochre more developed, especially on the hindwing; shape normal; the bright spot outside the cell-dot and the 
extended apical patch of the forewing are distinctive. Mt. Goliath and the Weylancl Mountains. 
Ch. eutmeta Prout (17 b). Quite distinct from anything else known and apparently not variable. The eutmeta. 
relatively large, trilobed white cell-mark of the hindwing is an interesting development. Dutch New Guinea, 
the type series from the Snow Mountains. 
Ch. perpicta Warr. (15 g). Both wings with termen somewhat more convex than in flavimacula, the perpicta. 
ochre still more dominant, the costal border and apex of the forewing light violet-grey, both wings with white- 
pupilled cell-ring ; the strong dark patch beyond middle of abdominal margin of hindwing distinctive. Khasis. 
Ch. mitigata Walk. (17 c). A rather small species, the division betw'een the purple-grey and yellow mitigata. 
colours of the forewing longitudinal, the markings of the yellow part variable, but not extremely; cell-dot of 
forewing black. Hindwing with the yellow colour basal, costal, apical and (narrowly) terminal, the large 
enclosed purple-grey area edged with reddish. Borneo. 
Ch. dinawa B.-Bak. ( — informiplaga Prout). (17 c). Hindwing bluntly angled, forewing noticeably dinawa. 
bent in the middle. The irregidar yellow central patches, containing the dull purple cell-dots, and the mottled 
distal borders are characteristic. British New Guinea (type) and Snow Mountains (type of informiplaga). 
ronensis subsp. nov. is a more brightly coloured form (especially as regards the purple parts) and has the cen- ronensis. 
tral yellow patches somewhat larger. The hindwing is slightly less angled, but I do not think the difference 
sufficient to denote a species. Ron Island (W. Doherty), a pair in the Tring Museum. 
Ch. sanguinea Warr. (17 c). In this and the next few species, the apex of the forewing is very acute, sanguined. 
its termen almost straight, sanguinea is known by the unusual brightness of the red parts. $ darker, with a 
yellow band outside the postmedian dots of the hindwing. Khasis. 
Ch. conspicuaria Swinh. (17 c) may possibly be a colour-form of the preceding, more flesh-pink, with conspicu- 
the postmedian series of black dots more conspicuous, set on a pale space. Khasis (type), Sikkim and Ceylon. arm ' 
Ch. abhadraca Walk. (17 c) is much more dark-clouded, leaving little trace of the pink colour except abhadraca. 
in some pale antemedian and postmedian spots. The underside, however, is much less clouded, nearly uniform 
vinaceous, extremely like that of the two preceding forms, from which, however, abhadraca seems to differ is 
its slightly less oblique-margined forewing. Described from Ceylon, but distributed in India, known also from 
Selangor, Sumatra and Sarawak.
