PIERINiE. 1 1 



forehead, compressed, clothed beneath with closely-appressed scaly 

 hairs, — terminal joint very small, blunt, scaly ; anicnncc 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 : forc-%vings 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-wings 

 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 ner\Tire 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 tibiee, and thickly spinulose. 



Aldomcn 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. Hccdbe, (Linn.), in Horsefield and Moore's Catalogue of 

 LepidoptcroiLs Insects in the Museum of the H. E. India Company 

 (1857), pi. i. ff. II, 1 1«, and in Moore's Lejpidoptera of Ceylon, 1881, 

 pi. 45, f. ic. ; and (as regards the pupa only) from a figure of (pre- 

 sumably) a Japanese species given by Mr. A. G. Butler on p]. vi. of the 

 Trans. Entom. Soc. Lond. for 1880, and the chrysalis skin of a Cape
