some distance, second one very little, before extremity of discoidal 
cell, third one short, originating far beyond cell, — fourth near third, 
also short, terminating at apex ; upper disco-cellular extremely short 
— in some cases hardly present, — middle one slender, of moderate 
length, slightly curved, — lower one rather longer, continuous of curve 
of third, joining third median nervule at a considerable distance beyond 
origin of latter ; submedian nervure curved upward near base and then 
more strongly downward ; internal nervure slender, almost straight, its 
extremity anastomosing with submedian nervure just beyond com- 
mencement of latter's downward curve. Hind-iuings : rather large ; 
costa prominent at base, and usually more or less so just before apex 
(in the European L. Geltis exceedingly so in both places) ; hind-margin 
more or less sinuate-dentate, sometimes with a more prominent denta- 
tion at extremity of first median nervule, or at extremity of submedian 
nervure ; inner-margins moderately convex, forming an incomplete, 
shallow groove ; costal nervure running close to and following curves 
of costa, ending at apex ; subcostal nervure branching at a long 
distance from base ; upper disco-cellular nervule slender, transverse, of 
moderate length, united to second subcostal nervule at some distance 
from origin of latter, — lower one extremely slender, or almost obsolete, 
longer and more oblique than the upper, joining third median nervule 
just beyond origin of latter ; internal nervure slender, much curved, 
very short, terminating on inner margin at some distance before middle. 
Fore-legs of $ very small, — femur and tibia about equal in length, the 
latter very densely hairy, — tarsus rather shorter, also densely hairy, not 
articulated, without terminal claws ; of $ much larger and longer, not 
hairy (except on under side of femur) but scaly, — femur much thicker, 
— tarsus fully articulated, spiny beneath, and with well-developed ter- 
minal claws. Middle and hind legs rather thick, densely clothed with 
scales, — tibia rather shorter than femur, its terminal spurs rather short, 
— tarsus longer than tibia, strongly spinose beneath, with strongly 
curved terminal claws. Abdomen slender, short. 
Larva. — Elongate, cylindrical, shortly pubescent ; much resembling 
that of the Pierinm. 
Pupa. — Bather stout, subangulated ; median dorsal line ridged, 
and dorso-thoracic prominence elevated and acute ; head with a single 
pointed projection curving inferiorly ; wing-covers projecting beyond 
line of abdomen. Suspended vertically by the tail only. 
(These characters of larva and pupa are given from figures of those 
of the European Lihjiliea Celtis, published by Hiibner, Duponchel, 
and Boisduval respectively.) 
The extraordinary length of the palpi, which form a most con- 
spicuous beak-like process in front of the head, readily distinguish the 
LihythceincB from the rest of the JErgcinidw, and, indeed, from all other 
butterflies. In robustness of structure, angulated fore-wings, and gene- 
ral neuration they approach Eurytcla and allied genera among the
