DESCRIPTIVE CATALOGUE. 



Godart, in the genus Polyommatus. (Enc. Meth. Hist. Nat. ix, p. 653.) They may be subdivided by 

 artificial characters, into the following groups. 



* Wings underneath with simple ocellate spots ; anal ocelli without metallic irrorations.

Wings above blackish brown, with a large white central area, extending obliquely from the middle 

 of the fore to the disk of the hinder wings: colour more intense on the fore wings, the posterior 

 margins of which are surrounded with a delicate white fringe, which is continued along the 

 inner border of the hinder wings, by a series of elongated silky hairs : tails black, tipt with 

 white : underneath the wings are pure satin white ; anterior wings, near the costa, marked with 

 four regular, equi-distant, minute brown dots, and on the disk, with a short curved line : 

 towards the posterior margin follows a curved striga, consisting of short lineolse or arcs, 

 not touching each other, but disposed obliquely between the nervures ; then, parallel with the 

 margin, two narrow strigae, the interior one being undulated, including a series of oblong, 

 attenuated, dark brown spots : these strigse and dots are continued uniformly through the hinder 

 wings to the anal region ; anterior to these is an interrupted macular fascia, resembling the 

 curved band of the fore wings, but with broader lineolse ; then a short, transverse, discoidal 

 arc : the hinder wings are further marked beneath with five intensely black spots, two marginal 

 and three basal ; the former are large, regularly round, of an intense black tint, one is placed 

 near the outer, the other near the inner apical angle, opposite to the caudal appendage, being 

 sepai'ated from the anal angle by two small dots : near the base are three transversely disposed 

 equi-distant dots of an intensely black tint. 



This species is comparatively scarce ; two specimens only are contained in our collection. In its habit and 

 markings it greatly resembles the individuals of the gg nus Polyommatus, and particularly the species last 

 enumerated. 



** Anterior wings underneath with an elongated oblique fascia at the base ; posterior toings, in 

 mx)st cases, with metallic irrorations on the ocellate spots in the anal region.

 The male. 



Wings above blackish brown, with a very broad band of yellowish white, situated on the posterior 

 edge, arising on the disk of the anterior, and passing obliquely over the disk and base of the 

 posterior pair ; marginal fringe grayish : underneath the wings are white, inclining to pale yel-
