bristling with long hooked {eroehueii) spines of equal length and curved backward. He says that 

 he has a larva of ^1. eadimis in alcohol, but, unfortunately, does not s|3ecifically describe it.

Imago. — 2 S ■ In the shape of the body and outlines of the wings allied to ^4. hlxectn. The 

 antenna^ are much as in A. lisectK, but the vestigial pectinations of the filiform tip are a little 

 more marked and each end in a fine seta. 



Fore wings acute toward the apex; outer edge oblique, not convex, l)ut very slightly excised 

 or hollowed out. Hind wings rounded at the apex and slightly angulated on the inner angle; 

 outer edge less full than in ^1. hlsccta. They reach, as in ^1. litsecta., a little more than one-iialf 

 or two-thirds the length of the abdomen; tip of the abdomen with an irregular terminal tuft. 



Body and fore wings tawny or pale brown rather than ocherous. A faint Isasal and a more 

 distinct linear extradiscal line, which is oblique and slightly incurved, ending on the costa a little 

 before the apex. Beyond this line the edge of the wing is slightly pinkish, and the entire wing 

 is finely dusted with dark scales. A faint, rather large, roundish ring-like discal spot, which 

 appears through from beneath. 



Hind wings deep pink, more tawny on the costal, outer and inner edges. No discal spot 

 above. 



Under side of the fore wings with a large squarish dark-brown discal spot, and behind it a 

 large part of the wing is deep roseate pink, this hue extending to the distinct extradiscal line, 

 beyond which the wing is frosted over with white scales. 



Hind wings beneath of the same color as the outer edge of the fore wings, being hoary or 

 tawny graj'. No discal spot visible beneath. On the fore tibial is a nari'ow but well-developed 

 epiphysis, which is about one-half as wide in proportion as that of ^1. montezHma n. .sp. : it is 

 lanceolate oval, nearlj^ three times as long as wide, narrow and pointed at the end. (PI. XXXVI, 



tig. l'.^-) 



The maxilliv in this spei'ics ai'e well developed comjiared with the other species we have 

 observed; the two are separate, but curled up, each maxilla nearly as long as the filiform tip of 

 the Z antenna. The palpi are small, slender, not easily perceived in the undenuded specimens; 

 they do not reach the front; they ascend and are much compressed. 



$ Larger than the $ , with the fore wings rounded and the outer margin Ijeyond the discal 

 line brownish; hind wings of a more obscure red; under side of the fore wings whitish, with a 

 common brownish line. Fore wings beneath with a black lunate discal spot, as in the $ , though 

 the disk is here whitish, not ro.seate (Boisduval). 



Expanse of the fore wings: S , 62 mm. ; length of one fore wing. <J , .'jO nun. ; breadth of one 

 fore wing, S . 14 mm. : length of the hind wings, S . 20 nnii. ; breadth of the hind wings, d' , 18 mm. 



Lari'ii. — Imperfectly preserved; the spines on second and third thoracic rings are quite long, 

 black, and toothed; the prothoracic collar is also provided with stifl' points or tubercles (Boisduval). 



Peters describes the larva as dark green, with a blue head and a lateral streak, the trunk 

 segments beset with siher spines. It lives on a spiny clim])ing plant. 



He also states that the larva of A. hreins (Taf. Ill, fig. 5) is very similar to that of .1. xnh- 

 angulata and lives on the same plant, yet the imago is ver}- ditt'erent. He found in Kio the lar\a 

 of this species on a spiny Mimosa.
