characters I conceive it to be a Sadyrid, and do not think that Mr. West- 
woods reasons for elevating the genus to family rank are good. 
The Libyrhernae are represented only by a single genus easily distin— 
guished from all other butterflies by the enormously long palpi projecting 
snoutlike forward. The genus is: Libythea. 
The £rycinidae have but a small representation in our fauna, generi- 
cally and specifically considered:and some of these are but doubtfully 
American. 
The genera said to occur here are as follows: 
Eyes hairy. 
Antennze with flattened club, thorax robust hind legs short stout........Nemiobius. 
Antennz with incurved club, thorax small, hind legs long and slender..... Charis§ 
Eyes naked or very finely pilose. 
Thorax ovate: primaries with costa arched, apex obtuse or rounded, median and 
posterior legs short, robust, densely clothed with long scales........ Eurygona. 
Thorax robust, costa of primaries straight or but slightiy arched apices subacute, 
middle and hind legs long and slender closely scaled.............. Lemonias. 
Thorax robust wings large entire, antennze short robust ; wings usually more or less 
4 . . 
suffused with metallic scales: beneath, with numerous patches of the same 
Eumaeus. 
Thorax small, apex of wing rounded, costa but little arched legs as before...Charis, 
Eumaeus is probably only an occasional visitant. It is sometimes 
classed with the Lycaenzdae but | prefer to leave it here for the present. 
The next family is the Zycaendae, characterized by their small size 
usually blue or copper color whence their name “blues” and “coppers” 
often with very slight filiform tails and sometimes (Z/ec/a) ornamented 
beneath with fine lines, whence they have been called “hair streaks.” 
The genera are as follows. 
Wings rather short ; costa of primaries decidedly arcuate ; secondaries elongate, inner 
margin longest, often dentate; generally with filiform tails. Species usually 
smoky gray or dull fuscous with an anal ocellate spot above ............ Thecla, 
Wings more elongate, costa but slightly arcuate, apices determinate: secondaries 
rarely tailed or dentate, more rounded, costal margin longest, color at least in 
one sex blue; often ocellate below ; eyes naked, spinulation of tarsi feeble.... 
Lycaena. 
As before ; eyes hairy, spinulation of tarsi strong.................... Chrysophanus. 
Wings large, primaries with rounded outer margin, costa arcuate at outer third: secon- 
daries triangulate entire, not tailed, color fulvousemarked with black.....Fenesica, 
Chrysophanus \ consider identical with Lycaena. With a few species 
only at hand or seperation of the genera in easy ; with a large collection 
of native and exotic species I have found it impossible to make any satis- 
factory division into well marked genera: the characters are obscure not
