the female the front legs are like the other legs, in the male 
they are shorter, without tarsal claws, and with the tarsi 
more or less aborted. This reduction of the fore legs is 
carried even farther in the next family, where it extends to 
both sexes, and the fore legs are unused. 
The caterpillars of the Lycaenidae present a very unusual 
form, being more or less slug-like, reminding one of the 
larvae of the Eucleidae. The body is short and broad ; 
the legs and prolegs are short and small, allowing the body 
to be closely pressed to the object upon which the insect is 
moving—in fact some of the species glide rather than creep; 
and the head is small, and can be retracted more or less 
within the prothorax. The body is armed with no conspic¬ 
uous appendages; but some of the species are remarkable 
for having honey-tubes which can be pushed out from the 
seventh and eighth abdominal segments, and through which 
honey-dew is excreted for the use of ants. Certain other 
species are remarkable in being carnivorous; one American 
species feeds exclusively upon plant-lice. 
The chrysalids are short, broad, ovate, and without angu¬ 
lations. They are attached by the caudal extremity, and by 
a loop passing over the body near its middle. The ventral 
aspect of the body is straight and often closely pressed to 
the object to which the chrysalis is attached. 
The Lycaenidae include two subfamilies; these can be 
be separated as follows :— 
A. Vein II of the hind wings without a branch near the base of the 
wing (Fig. 465). Lyc;enin;e. 
AA. Vein II of the hind wings giving off a spur (the tip of vein I) 
near the base of the wing. p. 394. Lemoniin^e. 
Subfamily Lyc^ENIN^E (Ly-cae-ni'nae). 
The Common Gossamer-winged Butterflies. 
This subfamily includes all of our common members 01 
the Lycaenidae; it is composed of three well-marked groups
