PSYCHE 



[October, 1902 



infumatcd, and with brown nerviires. Fore 

 wings with two arcuate series of large oval 

 clearer paler or ainber-like spots in the inter- 

 spaces beyond the cell, subparallel to outer 

 margin, a dusky margin and a pair of dusky 

 dashes enclosing a broad oblique clearer 

 band between them near apex of cell; an 

 orange stripe witli an enclosed broad black 

 stripe following the inner margin. }Iind 

 wings margined narrowly witli black, in 

 which, beneath, are a series of transverse 

 white dashes. Expanse So mm. Early 

 stages: iniknown. — Southern Texas. 



Subfamily HELICONINAE. 



Butterfly: Head unusually broad. 

 Palpi small, compressed, the fringes 

 moderate. Antennae naked or sparingly 

 scaled, e.xceptionally long, straight, the 

 cluli well marked, sometimes abrupt. 

 Fore legs of both sexes excessively atro- 

 phied, short and sparsely clothed with 

 short hairs. Fore wings very long and 

 narrow : none of the nervures swollen at 

 the base; internal nervure absent; cell 

 of hind wings short and closed or open ; 

 costal nervure extending to the outer 

 margin. Abdomen exceptionally long 

 and slender in most genera. Highly 

 variegated and of lively colors, but rarely 

 with delicate markings, generally similar 

 above and beneath. Females with a pair 

 of extensile club-shaped stink-pads at tip 

 of abdomen, between the two last seg- 

 ments, brought into use when seized. 

 Males with a similar pair on the inner 

 side of the claspers. Egg: Thimble- 

 shaped, considerably higher than broad, 

 the outer portion of the domed summit 

 with unusually large cells, the more or 

 less direct continuation of the large quad- 



rangular cells upon the sides. Caterpil- 

 lar at birth : Head scarcely larger than 

 segments following. Body cylindrical, 

 scarcely tapering, uniform in color ; 

 ranged appendages very long, slender, 

 and arcuate and generally, in our species 

 always, clubbed. Mature caterpillar : 

 Head armed with long and slender aculi- 

 ferous coronal spines. Body cylindrical, 

 submoniliform, more or less and deli- 

 cately spotted or marmorate or blotched 

 on the sides, armed with series of excep- 

 tionally long and slender, briefly and 

 sparsely aculiferous spines. Feeds only 

 on Passifloraceae, whence Miiller in 

 Brazil terms these insects maracuja but- 

 terflies. Chrysalis: Of very bizarre 

 appearance; with highly conspicuous 

 prominences in several places producing 

 the most grotesque and distorted forms; 

 especially are the ocellar prominences 

 strongly compressed and generally ex- 

 cessively elongate and serrate, the wing- 

 cases are excessively medioventrally 

 protuberant and the sides of the dorsal 

 surface of the third (sometimes second 

 and third) abdominal segments promi- 

 nent, produced or lamellate ; thorax and 

 abdomen rather deeply separated. In 

 coloring much variegated. 



Contains but a single tribe, Heliconini. 



Synopsis of the genera. 



I. Apostraphia. Butterfly: Fore 

 wing distinctly more than twice as long 

 as broad, its cell fully half as long as 

 wing ; cell of hind wing closed. Egg: 

 Tapering only on the uppe'r third. Cat- 

 erpillar at birth : Three principal rows
