360 RHOPALOCERA. 
long slender coxa, which is slightly produced beyond the trochanter-coxal joint; femur 
swollen=# coxa; tibia and tarsus about=femur, and both of them cylindrical. Front 
legs of the female slender but perfect, with five tarsal joints, claws, &c. 
Palpi exceedingly long, the terminal joint longest and gradually tapering to the end. 
The antenne have about thirty-eight joints, and terminate in a well-defined club. The 
secondary male organs have a tegumen with a central spine which terminates in a short 
depressed hook ; the harpagones are simple lobes, with rounded extremities projecting 
beyond the hook of the tegumen, and with slightly hairy lateral surfaces but no spines. 
Above the tegumen, and apparently formed by an independent prolongation of the 
penultimate segment, is a blunt projection, and on either side of it a long recurved hook : 
the shape of this piece is very similar to that of the tegumen itself in many Erycinidee.

This species has a very wide range over South America from the Argentine Republic 
northwards, and it is also found throughout our region. On the upperside the 
coloration of the wings is fairly constant, but we notice in some specimens that the 
white spots of the primaries are of a russet colour, though this peculiarity is not 
confined to any special locality. On the under surface, especially of the secondaries, 
the variation is considerable, some specimens having these wings mottled grey with 
clouded patches of brown, in others the surface is of nearly uniform tint. 
Though found throughout our region, L. carinenta exclusively frequents the hotter 
portions of the country. Mr. Champion met with it on river-banks, alighting on stones 
or on small twigs, and when at rest the wings are closely shut and the primaries are 
placed very far back, giving the insect in this position a very peculiar appearance. 
Mr. Champion considers that in its habits the resemblance of LZ. carinenta is much 
more with the Nymphalide than with the Erycinide.
