PIERIN^. 
forelieacl, compressed, clothed beneath with closely-appressed scaly 
hairs, — terminal joint very small, blunt, scaly ; anUnnm rather short 
and thick, with an elongate, very gradually formed, depressed club, 
blunt at the tip. 
Thorax very short, slender, clothed with scales and short hair. 
Wings large and thin : fore-wings rather elongate, more or less trun- 
cate ; costa strongly arched at base, but thence only slightly so ; apex 
usually rounded or moderately pronounced, sometimes acuminate ; hind- 
margin more or less convex ; posterior angle usually well-marked, but 
sometimes rounded ; inner margin slightly concave about middle ; costal 
nervure much thicker than the others, ending at or a little beyond 
middle ; four subcostal nervules, — the first originating about one-third, 
the second only a little, before extremity of discoidal cell, — the third 
and fourth forking at some distance beyond cell, not quite half-way 
to apex ; upper radial nervule united to subcostal nervure about 
midway between end of cell and third subcostal nervule, — lower one 
originating at junction of disco -cellular nervules, of which the upper is 
shorter and less curved inwardly than the lower ; discoidal cell rather 
broad, terminating somewhat truncately about middle. Hind-iuings 
bluntly obovate, but sometimes with hind-margin sub-angulated at ex- 
tremity of second median nervule ; costa more or less strongly arched 
from base ; anal angle mostly rather marked ; inner margin moderately 
convex, so as to form a pretty complete but wide and shallow groove 
for abdomen ; pre-costal nervure much atrophied, scarcely traceable ; 
costal nervure arched, ending beyond middle (sometimes not very far 
before apex) ; first subcostal nervule arched, given off just before extre- 
mity of discoidal cell ; upper disco-cellular nervule rather short, almost 
straight — lower one fully twice as long and obliquely angulated ; dis- 
coidal cell rather short, but widening outwardly, terminating truncately 
before middle. Legs slender, scaly ; fore and middle femora longer, 
hind-femora much shorter, than tibiae ; terminal tibial spurs minute ; 
all tarsi longer than respective tibiaB, and thickly spinulose. 
Abdomen slender, elongate (not quite as long as inner margin of 
hind-wings), much compressed laterally, slightly arched. 
Larva. — Of the ordinary Pierine form, towards extremities only 
slightly attenuated ; clothed with a very short pubescence. 
Pupa. — Slender, laterally compressed, much attenuated and sharply 
pointed at extremities ; wing-covers very prominent ventrally, laterally 
flattened into a very convex keel. 
These characters of larva and pupa are from figures of the early 
stages of T. ITecahe, (Linn.), in Horsefield and Moore's Catalogue of 
Leindopterons Insects in the Museum of the H. E. India Com2Ktny 
(1857), pi. i. ff*. I I, I la, and in Moore's Lepidoptera of Ceylon, 188 I, 
pi. 4 5 , f . I c. ; and (as regards the pupa only) from a figure of (pre- 
sumably) a Japanese species given by Mr. A. G. Butler on pi. vi. of the 
Trans. Entom. Soc. Lond. for 1880, and the chrysalis skin of a Cape
