Debis and Satyrodes have the veins very slightly and gradually swoll- 
en or inflated. The latter has the secondaries entire, much as in /Ve- 
nympha, while Debis has them dentate and subcaudate. 
Gyrocheilus has two veins inflated: the antennal club is very gradual 
and not flattened, and the tibize are profusely spined. Our single species 
is black, the primaries with small white dots toward apices, the second- 
aries with outer margin more or less broadly orange. The hind wings 
too, are dentate. 
Hipparchia has somewhat produced primaries, and very short middle 
tibia. A single species, Azdigsi occurs in our fauna; it is dull smoky 
gray, all wings with an irregular pale sabmarginal band, in which are 
ocelli. 
Satyrus has the veins very suddenly inflated; the primaries rather 
large, secondaries with outer margin somewhat dentate or waved. ‘The 
species are of moderate size, and the primaries are furnished with one, 
two, or three ocellate spots often set in a pale submarginal band. Be- 
neath, the secondaries have usually a sub-marginal row ofocelli The 
species of this genus are very variable and largely opinionative. They 
afford excellent examples of local races, breading true to themselves; but 
in some places intergrading. 
Chionobas is readily distinguished by the greatly produced apices of 
primaries, the thinly scaled wings, and the unusually ample secondaries, 
The species are northern, ur mountainous. 
The Libytheinae are very readily distinguished by their long palpi, 
which project forward far beyond the head, forming an obvious snout, 
resembling that of some of the De/foid genera. A single species of Liby- 
thea represents the sub-family in our fauna. 
The Lrycinidae or gossamer winged butterflies are rather small, 
usually reddish or fulvous in color, showing their relationship to the 
following Lycaenidae. Lemonias is rather a robust form, with the costa 
of primaries straight or little arched. Charzs is much slighter and the 
wings are more rounded. umaeus has the wings more or less suffused 
with metallic scales, and on the underside are silvery blotches. 
Nemeobtus resembles Chrysophanus in color and maculation; but the 
primaries are more acute at apex. None of the genera are well represent- 
ed in our fauna, and the species are southern and southwestern. _ 
The Lycaenidae—blues, coppers and hair streaks in common parl- 
ance— are readily recognized by the small size, the marked colors which 
led to their popular names, and the apparently complete foretarsi of both
