LYCAENIDAE: THECLIDI. 1819 



This caterpillar is attacked in Missouri, according to Riley, by Chalcis 

 flavipes (88:14, 15) and Pteromalus pupanim (89:1, 2), and Judge 

 Thomas has also raised the former from it in Georgia.

Imago. Front of head seen from the face of the same width as one of the eyes. 

 Eyes moderately full, sparsely, briefly and uniformly pilose. Antennae very delicate, 

 half as long again as the abdomen, separated at base by three-fourths the width of the 

 front of the head, composed of about thirty joints of which eleven or twelve form the 

 long ovate compressed club, which is three and a half times as long as broad, broadest 

 beyond the middle, increases very regularly in size on the basal half, but terminates 

 more abruptly in a slightly produced, rounded, naked tip, into which four joints 

 enter; the broadest joints are about five times as broad as long, and about five times 

 as broad as the stalk where the longest joints are about five times as long as broad. 

 Palpi if appressed to the head would just fail of reaching the base of the antennae, 

 slender, the apical of about the same length as the middle joint and very slender. 



Outer margin of fore wings sinuate, the neuration not affected in the male by the 

 presence of the discal spot, being the same in both sexes. Cell half as long as the 

 wing, truncate at tip and scarcely narrower than in the middle, the lower half closed 

 by a feeble vein, the origin of the subcostal and median nervures much as in the 

 female of Jlitura. Hind wings with well rounded outer border, the lower median 

 nervule produced to a thread-like tail, the outer two-fifths of the inmsr margin roundly 

 and angularly excised. First median fork nearer the base of the win^ than the sub- 

 costal fork. 



Fore tibiae three-fourths the length of the hind tibiae, of the same length as the 

 fore tarsi ; the latter, in the male, bearing at the tip only a pair of downtumed, scarcely 

 arcuate spines, barely larger than the other spines. Hind tibiae and tarsi of equal 

 length, the latter, excepting the apical joint, armed beneath with crowded, slender 

 spines, excepting on the basal half of the basal joint very long, much longer than the 

 width of the tarsi. Claws minute, bent with a rounded curve in the middle, finely 

 pointed; paronychia broad at base and rounded with an inferior, upcurved, delicate, 

 equal, compressed finger, half as long as the claws. 



This genus is confined, so far as I know, to only a single species, whose 

 range is given below ; it is by no means impossible, however, that Central 

 American forms, which I have not been able to examine, are to be referred 

 here. Nothing is known of the earlier stages.
