PIERIN^. 
8i 
Ibasal and middle joints densely clothed beneath with projecting 
hairs of unequal length, — terminal joint small, thin, rather acute, 
directed forward, clothed with short appressed hairs ; antennm short 
and rather thick, with a somewhat abruptly-formed, broad, flattened 
club, blunt at the tip. 
Thorax rather robust or moderately slender, clothed superiorly 
with close silky hair (longer laterally and posteriorly), and inferiorly 
with a shorter, denser down. Fore-wings with costa but slightly 
arched ; apex varying from rather acute to rounded ; hind-margin 
entire, rarely prominent in apical portion, sometimes convex in middle 
(especially in $) ; inner margin almost always nearly straight, or but 
slightly hollowed about middle (but in the Fausta group prominently 
convex in $) ; costal nervure extending to about middle ; first and 
second subcostal nervules originating not far apart at some distance 
before extremity of discoidal cell, and usually closely approximate 
throughout, — the first often almost touching costal nervure, — third 
nervule short, originating nearer to apex than to extremity of cell, and 
usually terminating at a^^ex, but sometimes very short and ending on 
costa; upper radial nervule united to subcostal just at extremity of 
discoidal cell ; upper disco-cellular nervule short (in Daira group 
extremely short) curved inwardly, — lower one three times as long, 
sub-angulated inwardly, moderately oblique inferiorly. Hind-wing: 
costa very prominently convex at base, but not strongly arched gene- 
rally (except in Suhfasciatus and the Fausta group) ; hind-margin entire 
or but very slightly sinuated ; costal nervure rather short, terminating 
at a little beyond middle ; second subcostal nervule usually originating 
before, or considerably before, extremity of discoidal cell (but in several 
groups at that extremity, and in the Daira group slightly heyond it) ; 
lower disco-cellular nervule long, sub-angulated, oblique, joining third 
median nervule at some distance from latter's origin ; internal nervure 
extending to beyond middle ; inner margins very prominent basally, 
and meeting so as to hide basal half or more of abdomen ; anal angle 
rounded. Legs of moderate length and thickness, scaly ; femora with 
short hair beneath ; tibia3 of fore and middle legs shorter, of hind-legs 
considerably longer, than femur, — their terminal spurs short ; tarsi 
long, spinulose beneath. 
Abdomen slender, rather short. 
Larva. — Kesembling that of Pieris, but stouter anteriorly, and 
segmental incisions deeper ; some short scattered hairs, sparsely distri- 
buted, but more numerous laterally ; dorsal surface with marked trans- 
verse rugae, and two transverse rows of tubercular spots on each segment. 
Pupa. — Head acuminate somewhat abruptly, but rather wide and 
with eye-covers prominent. Thorax dorsally moderately convex, late- 
rally very slightly sub-angulated at bases of wing-covers. Wing- 
covers exceedingly prominent ventrally, highly convex in outline, but 
laterally compressed keel-fashion. Abdomen slender, straight, dorsally
