Egg. Tlarale. about e<inally tninenle above and below, the lint or sunken portion 

 of the upper surface, Ini-ludln^. to(;elher with the nderopylie pit, fully one-fourth, 

 sometimes more than one-half the diameter of the ejts, rejiularly and very profusely 

 stuilded with hijih and rather coarse prominences of varying character, connected 

 by n lower, almost equally coarse tracery, within widch the plt-Ukc cells are situ- 

 ated : nderopylie pit very deep with steep walls. 



Caterpillar at birth. Head smooth, illstlnctly narrower than tlie llrsl thoracic 

 sej:ment. Tliorncle and abdominal sojiments of about eciual width. The hinder seg- 

 ments of the abdomen fused and fully tw iee as Ions; as those immediately precedinf; it. 

 furnislied a little behind the middle w ith a lariie circular coriaceous depression. The 

 llrst tlioraeie segment similarly furnished with a lozenge-shnped, laterally produced, 

 coriaceous shield, .\bdominal segments furnished with rejrnlar series of tall conical 

 papillae, bearing splculiferous hairs, wiiich extend to a certain extent upon the tho- 

 racic segments but on them lose in part their serial character. On the abdominal 

 segments there Is always found a laterodorsal series, consisting of two or more, bearing 

 long curving hairs directed to a greater or less extent backward; while beneath the 

 spiracles is a compound scries of from three to live longer and shorter, generally 

 straight and outward directed hairs. Between the laterodorsal .series and the spiracles 

 is a lateral series of sinootli. hemisplierical, naked lentUies, and on the last compound 

 abdonnnal segment a curving series of four or live similar Icnticles of unequal size. 



Mature caterpillar. Body slightly slenderer than in the other groups ; segments 

 scarcely prondnent in any part, body covered with hairs, mostly very short, but at the 

 laterodorsal ridge and the substigmatnl fold they are tivo or three times longer, 

 thousfh still short. 



Chrysalis. Body shorter and stouter and especially the whole* abdomen fuller 

 than in the other tribes ; dermal appendages consisting of cylindrical hairs, w inch are 

 eipial, Ujpering only at tip, profusely provided with minute spicules, w inch diverge at b. 

 slight angle from the stem. 



Tliis tribe of Lj'cacninae contains some of the most attractive butter- 

 flies. Their elegant form, ilclicate niarkinas, small size and active move- 

 ments all combine to render tiiem very fascinating. They may generally 

 be distinguished from the other tribes by their more angulated fore wings, 

 their dark brown colors and by the delicate striped markings on the under 

 surface of the wings, markings which have gained for these butterflies the 

 popular name of "Hair streaks.'" Their hind wings are also comnionlv 

 furnished with thread-like tails — whence the title Armati, given them by 

 Hiibner. Tiie anal angle of tiie hind wings is not infrequently lobed and 

 bent downward at a right angle ; and the fore wings of the male often bear 

 a small, dull, oval spot near the middle of the front margin, wiiich is filled 

 with androconia and frequently disturbs the regularity of the reins at that 

 point. Besides this secondary sexual peculiarity, the front of the face of 

 the male bears a kind of beard, a bristling tuft of liair like scales, wanting, 

 or very thin, in the female.
