200 THE BUTTERFLIES OF NEW EXGLAXD. 



Upper organ of male abdominal appendages rather small, the body a litte tumid, the 

 hook separated by a rather deep sulcation ; hook very mnch longer than the body, curved 

 considerably dowmvard, shaped much as in Cissia; lateral appendages unusually Ijroad 

 on the basal half, beyond tapering to a point. Clasps broad, less than three times as 

 long as broad, tapering apically, but not pointed, the upper edge bearing just before 

 the extremity a large, iuAvard directed, depressed tooth. 



Egg. Almost globular, but ■svitli somewhat truncate base, the surface uniformly 

 reticulate, Avith irregular polygonal cells of nearly uniform size, forming shallow lenti- 

 cular depressions. 



Caterpillar at birth. Head large, about twice as large as any body segment, higher 

 than l)road, broadest near the base, well rounded except for the presence of large, 

 mammiform or conical bosses, the largest of which are at the summit externally, one on 

 either side directed upward and outward, while a similar smaller one is found in the 

 middle of each cheek; the coronal pair give rise each to two simple, short hairs arising 

 from papillae, the genal to a single hair. Triangle large, much higher than broad, near 

 the base Avith a transverse row of two pair of minute hair-supporting papillae. Man- 

 dibles large, chisel-edged, entire. Body cylindrical, uniform, slightly tapering poste- 

 riorly, the terminal segment bluntly furcate. Appendages consisting of slender, 

 delicately clubbed, papillae-supported, moderately short hairs, less than half the 

 length of the segments, excepting on the four last segments where they are sometimes 

 much longer; they are arranged in an anterior subdorsal, a posterior laterodorsal 

 (becoming supralateral on the thoracic segments), an anterior laterostigmal and infra- 

 stigmatal series, the latter double on the abdominal segments. 



Mature caterpillar. Head massive, well rounded, deep, narrower than the body, 

 rounded in every direction, broader and deeper below than above, broader than high, 

 higher than deep ; the summit produced externally on either side to a conical eleva- 

 tion, studded Avith conical papillae, Avhich otherAvise are rather sparsely distributed 

 over the head, each giving rise to a fine hair shorter than itself. Ocelli five in number, 

 tAVO attingent in front, the loAver of them four times as large as any of the others, tAvo 

 others forming a row Avith the large ocellus, equidistant, and the posterior one at the 

 angle of the right angle, connecting the loAvest (just above the antenna) and the loAver 

 edge of the large one. Body slender, stoutest in the middle, gently tapering in either 

 direction but especially posteriorly, the final segment terminating in closely approxi- 

 mate, slightly divergent, long and slender, conical, not finely pointed, papillate forks; 

 abdominal segments divided by transverse sulcations, Avhich are fainter beloAV the 

 middle, into six subequal divisions, the anterior the broadest, and the next, on Avhicli 

 the spiracles occur, a little larger than the remainder ; surface studded rather abun- 

 dantly and Avith much uniformity Avith minute conical papillae, each supporting a not 

 delicate tapering hair of about its OAvn length; spiracles elevated, long-oval, subfusi- 

 form. Legs short, stout, conical ; claAvs exceedingly delicate, straight. Prolegs very 

 short and stout, tapering. 



Chrysalis. Head and thorax much appressed in front so as to present a nearly flat 

 surface, at an angle of 75° or less Aviththe nearly straight ventral surface of the ante- 

 rior half of the body. Dorsum of thorax abruptly rounded at almost right angles, 

 distinctly carinate on the mesothorax, scarcely contracted at the metanotum, but the 

 abdomen enlarging slightly on the first three segments and then diminishing Avith some 

 rapitlity and regularity, the movable joints having a conical form. Ocellar tubercles 

 trigonal, more or loss prominent, the head about half the Avidth of the thorax, Avhich 

 rapidly narroAvs toAvard it. Inner dorsal margin of the Avings developed into a strong 

 carina Avhich dies out just before the outer margin. Tongue case terminating some 

 distance short of the Aviugs. Cremaster considerably extended, tapering, depressed. 

 Spiracles ovate, slightly embossed. 



This genus is nearly allied to Cissia ; like it, it is peculiarly American 

 and probably occupies a very similar extent of territory, although seldom
