.5-58 HESPERIID.i:. 
marginal series of broad vinous-brown spots, one at end of each vein. Tliorax and abdomen 
■white; collar, top of head, palpi, and tip of abdomen pale ferruginous; tip of palpi and 
antennEB black ; legs i)ale ferruginous above, purple-brown beneath. 
" Expanse 2| inches." (Moore, I. e.) 
Oue male specimen was taken by a native collector at Pii-tsu-fong, Western 
China, in July. It differs only from the Bengalese type in Mr. Moore's 
collection in having a rather deeper apical border to primaries ; the spots 
at ends of median nervules are larger; the discal spots on secondaries are 
very faint, except that between the costal and subcostal veins. 
The colom" of apical border and also of the spots is rather blackish than 
vinous brown, as mentioned by Moore in his description of C. pieridoidcs. 
Mr. Doherty *, who obtained male specimens near Margherita, Assam, says : — 
" They fly in the darkest parts of the forest towards the end of the afternoon, 
alighting, like the other butterflies of the Tagiades group, with outspread 
-wings. In the morning they lie concealed, adhering closely to the underside 
of leaves. No one who sees it floating lazily with level wings up and down 
the bed of a stream, its pure white upper surface singularly conspicuous in 
the gloom of the jungle, can doubt that the species is protected. I see no 
reason to suppose that it mimics any Pierid. In a very vague way it resembles 
the Geometrid genus Eucliera, which is likewise protected, and has somewhat 
similar habits. 
" The entire body and wings of this butterfly are saturated with a powerful 
and delicious odour of mingled vanilla and heliotrope. This is often per- 
ceptible as it flies past. After pinching the insect, the scent is sometimes 
obvious for hours afterwards on one's fingers. After lying two weeks in its 
paper, a dried specimen still gave out perfume. None of the sweet-smelling 
Lepidoptera known to me, not even the Lethes, Enploeas, or CalUduJas, have a 
more powerful odour. Yet it seems to have no specialized scent-organ (such 
as those genera have), unless the tufts on the hind tibiae, present in many 
other Hesperians, be so considered. 
" I unluckily caught no female, though I once saw a male cu'cling round a 
dark-coloured Hesperian, which escaped. It is, perhaps, rash to speculate 
where certainty may before long be attained, but the female is most likely 
dark."
