PAPILIONIN.E. 195 



short, not rising above half height of head, pressed close against face, 

 clothed with longish hair and scales inferiorly,— basal and middle johits 

 about equal in length, terminal oue minute ; antennce of moderate 

 length or rather long, variable in thickness, — the club long, gradually 

 formed, usually curved upward and outward; haiisiellaiii long. 



Tliorax rather robust ; prothorax forming a distinct neck. Wings 

 exceedingly varied in outline, large, with strong nervines. Fore-wings 

 usually sub-triangular, often more or less produced apically, sometimes 

 very narrow and elongate, rarely falcate ; costa slightly or moderately 

 convex ; costal nervure very thick, and extending about three-fifths 

 length of wing ; subcostal nervure five-branched, very close to costal 

 nervure as far as its second nervule, — its first and second nervules 

 closely approximate, long, given off not very near to each other, but far 

 before extremity of discoidal cell (iirst in Lcunidas and Pylades, and 

 allies, greatly abbreviated and ruiniing into costal nervure), — third 

 rather long, curved, given off at end of cell, running close to second, 

 and ending at apex, — fourth and fifth branching off far beyond end of 

 cell, but nearer to it than to apex, rather short (fourth much arched and 

 remote from third) ; disco-cellular nervules all fully developed, — the 

 first and second almost vertical, or slightly inclined inwardly or out- 

 wardly, but the third very oblique inwardly, and so directly continuous 

 of median nervure that lower radial nervule has all the appearance of 

 an additional fourth median nervule ; an interno-mediau nervule unit- 

 ing median and submedian nervures near their origin, so as to form a 

 small sub-discoidal cell ; internal nervure well developed, free, termi- 

 nating on inner margin at some distance from base ; discoidal cell long 

 and broad ; $ in some species with the lower radial and three median 

 nervules, and the submedian nervure on disc, bordered above and below 

 by a long space of closely-appressed fine silky short hairs, narrowing to 

 a point both inwardly and outwardly. Uind-ivings always more or 

 less elongate inferiorly (sometimes extremely so), commonly tailed at 

 extremity of third median nervule ; costa moderately arched ; apex 

 much rounded off; hind-margin more or less dentate, sometimes so 

 strongly as to bear several short tails ; inner margin hollowed (in ^ 

 sometimes folded back and bearing a coating or fascicle of hairs) ; pre- 

 costal nervure forked, its lower branch united to costal nervure so as 

 to form a small prediscoidal cell ; costal nervure ending at apex ; first 

 subcostal nervule given off far before extremity (at from one-third to 

 two-thirds length) of discoidal cell ; disco-cellular nervules straight, 

 upper one longer (sometimes much longer) than lower, oblique ; dis- 

 coidal cell short and much narrower tlian in fore-wing; submedian 

 nervure incurved, ending at anal angle ; internal nervure wanting-. 

 Legs long, usually thick ; ibre-coxie free, clothed w^ith short hair ; 

 femora without hair, or with a very little inferiorly, — first pair longer, 

 second as long as, third pair shorter than, tibiiu ; all tibia) strongly 

 spinulose, — terminal spurs of second and third pairs rather long.
