94 DESCRIPTIVE CATALOGUE. 



nent; hinder wings narrow and lengthened, the ground colour being uniformly diffused over the 

 whole surface to a very narrow black marginal thread ; anal appendages tipt externally with black, 

 and surrounded, within the brown fringe, by a white thread extending also towards the tail ; in 

 the female the wings are saturated testaceous with a slight cupreous lustre, the colour being 

 uniformly diffused over the surface, increasing in strength towards the margins, but without 

 denned borders : underneath the surface is satin-gray, with a faint glaucous cast, varying in 

 intensity of tint in different individuals ; on the disk of each wing stands a short oblong double 

 streak consisting of two parallel grayish brown lituraswith a medial and two lateral narrow white 

 lines ; between this and the posterior margin a more saturated brown band pervades both pair, 

 being nearly regular until it reaches the anal region, where, after a sudden flexure, it stretches 

 directly across towards the internal margin, being bordered with a white striga exteriorly in the 

 anterior and on both sides in the posterior pair, the tint becoming more intense as the band 

 approaches the anal region, having a bright silvery lustre in well preserved specimens ; the 

 extreme anal angle is ornamented with two regularly round deep black ocellate spots, the exte- 

 rior one being bordered internally with a brilliant orange lunule, the interior one, somewhat 

 larger in size, covering the anal appendage, and being surrounded by a delicate white ring 

 ciliated posteriorly; the intermediate space is occupied by a roundish group of greenish silvery 

 atoms, bedded on a blackish patch, which sends off obliquely a narrow streak towards the inner 

 margin. The body is testaceous brown above, gray underneath, and covered on both sides with 

 delicate silky hairs ; the antenna are annulated, the club has a ferruginous tip, and the tails are 

 black with a whitish extremity. 



Our museum contains eleven specimens, of which five are females.
