Mr. E. Doubleday on some new species of Butte? flies. 419 



the anal angle, and a rather broad transverse band of the same 

 colour beginning on the costa beyond the discoidal cell and ter- 

 minating near the middle of the outer margin. Posterior wings 

 black/ the disc traversed by a broad pale yellow vitta which ex- 

 tends from the base nearly to the outer angle ; the costa is of a 

 neutral tint, furnished in the males with a long tuft of hair as in 

 the Heliconians. 



Below. — All the wings black, the markings as above, with the 

 addition of a marginal series of small white spots, preceded by a 

 narrow ferruginous line broken on the anterior wings. The base 

 of the posterior wings has a yellow vitta on the costa. 



Head black ; thorax above ferruginous, below black ; abdomen 

 above black, below yellow. 



Lept. Eunot. Alis anticis falcatis nigro-fuscis, vittis duabus basali- 

 bus longitudinalibus maculaque bifida aurantiacis, fasciis duabus 

 macularibus obliquis apiceque flavis, posticis aurantiacis fimbria 

 lata nigro-fusca maculis tribus apicalibus flavis. Exp. alar. 3 unc. 



Anterior wings falcate, the base with a longitudinal orange 

 vitta in the cell and a narrower one on the inner margin, at the 

 extremity of which is a spot bifid anteriorly, of the same colour. 

 Beyond there is a transverse yellow macular band, composed of 

 five spots surrounding a square black patch placed on the disco- 

 cellular nervure and of a large oval spot beyond. This band is 

 followed by another, composed of a spot on the costa divided 

 into three parts by the nervures, and of two approximating oval 

 ones beneath it. The apex itself is yellow with the nervures fus- 

 cous. The outer margin is tinged with brown. Posterior wings 

 large, orange, with a broad fuscous fimbria shading to brown on 

 the margin itself, and marked at the apex with three yellow spots. 



Below. — Anterior wings nearly as above but paler, the two 

 vittse and the orange spot confounded together ; the apex with 

 some small white clouds. Posterior wings brown, the disc clouded 

 with yellow, the posterior margin, especially towards the apex, 

 freckled or clouded with white. 



Head and thorax grayish ; abdomen fuscous above, beneath 

 yellowish.

 longitudinalibus aurantiacis, fascia obliqua maculari aurantiaca al- 

 teraque flava, posticis umbrino, nigro, aurantiacoque vittatis. Exp. 

 alar. 3 unc. 



Anterior wings falcate, fuscous, paler towards the outer margin ; 

 the base with three longitudinal orange vittse, one on the costa, 

 one on the inner margin, the intermediate one extending along 

 both sides of the median nervure a little beyond its first branch,
