198 HAUSTELLATA.-^LEPIDOPTEBA. 



Genus CXCI. — Ephyra, Duponchel. 



Palpi slender, short, drooping, slightly squamous, not extending beyond the 

 forehead; terminal joint slightly exposed, subovate; triarticulate, the basal 

 joint slender, slightly bent and a little thickened at the apex; second rather 

 shorter, subcylindric, a little attenuated at the apex; terminal elongate-ovate, 

 half as long as the second : maxilJce long. Antennce of the males bipectinated 

 for about half their length, the apex simple, slightly pubescent within ; of the 

 females entirely simple and slightly pubescent on the inner side : head small : 

 e^es globose : thorax slender : wings slightly expanded during repose, entire ; 

 the hinder margin of the anterior slightly repanded, the apex acute, the hinder 

 angle rounded ; posterior obsoletely angulated in the middle ; the base of all 

 more or less pulverulent, and the centre of the typical species vrith a circular 

 spot or ocellus, of the remainder with a broad common striga : abdomen slender, 

 stouter and acute in the females. 



Larva slender, smooth, without tubercles; the head large, rounded; pupa 

 truncate anteriorly, coarctate in the middle, the apex acute ; suspended tail 

 downwards, with a silken band across the breast, after the manner of the 

 Pontise. 



These pretty insects, which form the genus Cyclophora of my 

 Catalogue, from the circle which adorns the disc of all the wings of 

 most of the species, may be known by that character, united to 

 their small size, pulverulent base of the wings, which have usually 

 one or more common strigse on them, composed of black dots, and 

 pale-ochraceous, yellowish, or rufescent ground colour : the antennae 

 of the males have the apical half simple, the anterior wings are 

 slightly falcate, and the posterior obsoletely angulated in the 

 middle : the pupa is truncate, and is suspended by a silken thread 

 across the breast.

Pale whitish-yellow ; the vdngs with a common repanded fuscous striga near 

 the base, and a second behind the middle, strongly and irregularly dentate, 

 having a fuscescent band accompanying it on its inner edge ; behind this is 

 an obscure striga, and on the hinder margin is a row of minute black dots : 

 cilia immaculate : between the strigae, in the centre, of each wing is a distinct 

 conspicuous black circle. 



Variable : in some instances the anterior striga is wanting, the place being 

 indicated by three black dots only ; in others the fuscous band adjoining the 

 posterior striga is either totally obliterated, or is so powerful as nearly to
