ARSENURA. I03 



to 4h inches. It is brown, with the fore-wings more or less 

 dusted with grey. Towards the base of the wings are some 

 rather indistinct brown Hnes, and at two-thirds of the length 

 of the costa, a well-marked brow^n or reddish line runs 

 obliquely nearly parallel to the hind margin, and is continued 

 more obliquely across the hind-wings. Near the extremity of 

 the costa of the fore-wings is a black spot dusted with blue, 

 placed in a lighter space running to the tip, and below the 

 inner half of this white stripe are two grey curves, bordered 

 outside with white, and inside by a brown or blackish zig-zag 

 sub marginal line, imperfectly double, and partly filled up with 

 white, running to the inner margin between the transverse stripe 

 and the hinder angle. There is a similar, but broader and more 

 festooned black sub-marginal line on the hind wings, bordered 

 again wdth grey or whitish, and this again internally by a 

 narrower and less distinct brown line. In the male, which we 

 have figured, the hind-wings are deeply concave on the hind 

 margin, and are slightly produced outwards at the lower and 

 outer angle; in the female, the concavity is slight, and the 

 wings are more rounded and scalloped. The female is the 

 sex figured by Cramer. It has the hind-wings dark brown 

 between the bands, and slaty-grey towards the base, and the 

 borders of all the wings dark reddish-brown. The larva, 

 which feeds on banana, is yellow, mottled with black, and the 

 head, extremities, and pro-legs arc red. 



Two other species, likewise occurring in Surinam and in 

 other parts of Tropical America, have been confounded with 

 this. One of these is A. armida (Cramer, Pap. Exot., iii., 

 pi. 197, fig. A), which is a dark brown moth, with the space 

 between the transverse stripes filled up with darker brown on all 

 the wings. Cramer's figure represents a male. The larva and 

 pupa are figured by StoU (pi. 19, figs, i, i A, B), and the 

 former is represented on our pi. cxx., fig. 4. It is black,
