158 CHRYSOCRASPEDA. By L. B. Prout. 
Pt. crypsaurea Bastelb. (15 b), described as a Ghrysocraspeda, probably belongs here. “Grey-lilac with 
dark gold-yellow spots." The only conspicuous one is the wedge-shaped spot of the forewing which, at about 
1 mm distant from the costa and reaching the 3rd radial, runs from near the distal margin to the middle of the 
wing, and the corresponding, ill-defined mark of the hindwing which reaches the base but not the distal margin. 
Goping, Perak, the type unique. 
Pt. vinosa Prout (16 k) founded on 2 99 (“N. Borneo" and Elopura, off N. Borneo), has about the 
expanse of average togata but the termen of the fore wing more strongly curved in the middle, thus highly 
oblique posteriorly, and has an irregular yellowish postmedian band and tornal patch on the forewing and 
yellow terminal spots on the hindwing. Its probable <$<$, also from N. Borneo, are strongly mottled with yellow 
in the central area of the forewing and throughout the hindwing and have in addition a more or less complete 
antemedian band. 
Pt. conversata Walk. (17 a). In coloration similar to the <$ of togata or with the bright ground-colour 
rather more pink (compare mimosa) the light yellow markings in the median area much more restricted, a broad 
line (irregularly angulated) taking the place of the central patch. Although described by Walker as long ago 
as 1861, from a Sarawak it has remained almost unknown, but a much damaged $ from the same country 
(Baram district) seems to agree essentially with it. 
Pt. anisocosma Prout (17 a). Hindwing much less bent at the 3rd radial. Very distinct in having the 
forewing, but not the hindwing, irrorated in large part with blackish fuscous, strongly so proximally (especially 
anteriorly); the yellow markings, too, show 7 considerable disparity on the respective wings. The unique type 
is a $ from Sungei Ujong, Malay Peninsula. 
Pt. dilucida Warr. Expanse 24 mm. Both wings bluntly angled at the 3rd radial. Perhaps the most 
distinctive feature is the almost diaphanous central area of the hindwing; the base, a costal spot and terminal 
band dark-clouded, the latter containing irregular yellowish subterminal spots. Prevailing colour of forewing 
yellow, more orange in posterior half, the costal area in part suffused with olive-grey, the lines broad but in¬ 
distinct, yellow; cell-dot black. Sarawak (type) and Singapore. 
Pt. rubricata Swinh. (17 a). Both wings highly gibbous; yellow, the markings of the forewing much 
obscured by purplish suffusion, only the median area anteriorly clear enough to show the type of marking of 
the hindwing; cell-mark linear, blackish. Hindwing with 1st line straightish, postmedian much bent, double 
except anteriorly, a short transverse streak behind them. Siam: Bulsit Besar, 1 
Pt. phlogea sp. n. (17 a). Shape less extreme, nearer that of tigrina ; $ antenna normal. Yellow markings 
of forewing intermediate between those of dipyramida and dracontias , its apex irrorated as in tigrina. Hindwing 
more variegated than in either, the termen only narrowly yellow; the 3 cell-dots large, purplish, almost con¬ 
nected into an angular figure. Dutch West Borneo, 85 miles above Pontianak, type $ in the British Museum. 
B. Section. Antenna of $ pectinate ( Heteroctenis Meyr.). 
Pt. tigrina Meyr. (17 a). Pectinations short and stout, only developed on outerside of shaft. Wings 
broad, the forewing moderately gibbous, the hindwing appreciably crenulate. Yellow, irregularly irrorated 
with orange; cellmarks blackish, that of the hindwing double; each wing with a large vinaceous cloud, bounded 
distally by a sinuous yellow line. S. E. Borneo, 1 9- 
Pt. dipyramida Prout (17 b). Antenna (9) as in tigrina. Hindwing strongly angled. The vinaceous 
forewing with yellowish mottlings in places and yellow fringe; the principal yellow markings are the two ir¬ 
regularly pyramidal patches, one beyond the cell, the other from the tornus. Burma: Tenasserim Valley, E. of 
Tavoy, type 9 , 2 further 9 $ collected with phlogea. 
Pt. dracontias Meyr. (17 a). Pectinations (9) much longer than in the two preceding, biseriate. Hind¬ 
wing, with the exception of the termen, nearly unicolorous purplish, with a group of 3 blackish cell-dots. Fore¬ 
wing more variegated, the purplish parts (a very large posterior patch and a large roundish subapical spot) 
being separated by deep yellow, somewhat as in oophora. Borneo; the one known $ has the purple parts some¬ 
what more variegated with reddish than the 99 - 
16. Genus: Clirysoeraspefta Hmps. 
(See Vol. 16, p. 51.) 
Certainly very closely related to Ptochophyle, only differing materially in the loss (or, in one exceptional 
instance, extreme reduction) of the areole, which leaves all the subcostals of the forewing to arise from a com¬ 
mon, long stalk. As with Ptochophyle , there are a few species in which the 9 antenna is bipectinate, indeed
