816 TIIK nUTTERFLIES OF NEW ENGLAND. 



compresscil siibcyliiulrical club, abruptly juul aluiost equally rounded at either extrem- 

 ity, equal throughout most of its length, the first two and last three joints dirainishing 

 in size, the last joint very slightly pointed at the apex; the club a little more than 

 one-third the length of the stalk, viewed from above twice, or viewed laterally three 

 times, as stout as the stalk and, viewed laterally, six times as long as broad, the last 

 two joints wholly naked, the others only naked beneath. 



Palpi short and slender, l)ut little longer than the eye, the terminal joint about three- 

 fifths the length of the penultimate and clothed only with recumbent scales, while the 

 other joints, besides being heavily scaled, are furnished beneath with a ratlicr heavy 

 fringe of pretty long, forward reaching hairs, all compressed in a vertical plane. 



Fore wings (39 : 17) two-thirds as long again as broad, the costal border slightly 

 convex on the basal third, beyond straight nearly to the tip where it is rounded a 

 little, tlie outer border nearly straight on the upper two-thirds, receding with a gentle 

 curve below, its general course at an angle of about 55° with the middle of the costal 

 border; inner border nearly straight, scarcely concave or bent at the middle, its 

 outer angle well rounded. 



Costal nervure terminating opposite the end of the cell. Subcostal with three 

 superior branches, the first arising a very little beyond the middle of the '-I'll ; the 

 second about midway between this and the apex of the cell, the third a little more 

 than half way between the second and the tip of the cell, the main stem hardly 

 flexed at the cross vein connecting the inferior nervule with it and tlie median, the 

 last only distinct next the main veins, the inferior nervule arising from its middle. 

 Cell slightly more than half as long as the wing and three and one-half times longer 

 than broad. 



Hind wiugs with the costal border greatly, suddenly and rouudl}' expanded at the 

 base, beyond scarcely concave, until toward the tip where it is broadly rounded with- 

 out sign of angulation ; outer border very regularly and considerably roundetl ; inner 

 border rather slightly and regularly bowed, the outer angle not rounded, more than a 

 right angle; submedian nervure terminating on the outer border just beyond the anal 

 angle ; Internal nervure terminating somewhat beyond the middle of the inner margin. 



No discal stigma nor androconia. 



Fore tibiae about four-flfths the length of the hind tibiae, and rather shorter than 

 the fore tarsi. Femora thinly fringed with long hairs. Middle and hind tibiae of 

 about equal length, armed at the tip with not very long spurs, concealed almost to the 

 apex with scales. First joint of tarsi a little shorter than the others combined, the 

 second nearly as long as the third and fourth together, and a little longer than the 

 fifth; joints rather abundantly armed on either side beneath with moderately long and 

 slender spines, the apical ones of each joint longest; under surface of all the joints 

 but the basal devoid of scales; claws very small, compressed, taperiug, curved only a 

 little, finely pointed; paronychia single, rather broad, compressed, tapering a little, 

 curved slightly toward the claw and also inward; pulvillus minute, projecting. 



Egg. Regularly echinoid, more than twice as broad as high, more flattened beneath 

 than above, broadest below the middle, the surface profusely studded with elevated 

 conical points, with five lower stellate rays diverging from them toward all neighbor- 

 ing points, forming everywhere a pentagonal reticulation, the cells of which are ex- 

 tremely small, smaller than in any other of our Theclidi. Micropylic area flattened, 

 but not sunken. 



Tliis American genus of Theclidi is better represented south of our 

 boundary than within it, at least two species Ijeing found in ^lexieo and 

 Central America. Our own species has been found in abundance only in 

 southern Arizona, and apart from that has a very anomalous distribution, 

 being only known in the northeastern United States b}' a specimen cap- 

 tured here and there.
