LEPIDOPTERA. 67 



with " alee integerrimce ;" namely P. Lysimon, P. Pheretes, and P. Damon ; there are likewise indications of 

 other foreign species, as the individual figured by Mr. Donovan, which, although the same in form and habit, 

 appears to be specifically different from those in our collection : and the P. Hanno of Cramer probably 

 belongs to the same group. 



** Margins of the hinder wings at the anal extremity angular, and produced to a short rounded point.

 Plate I, fig. 1 ; 1, a. 

 Disk of the anterior wings and almost the whole of the posterior wings white above : base of both 

 pairs, and a broad belt along the anterior and posterior margins of the fore wings, blackish brown ; 

 hinder wings marked with a few scattered dots of blackish brown and surrounded by a streak of the 

 same colour, interior to which is an interrupted series of delicate brown lines : both pairs are covered 

 from the base to the disk with an azure irroration ; (and in one of our specimens the disk is marked 

 with an obscure curved fascia of brown :) beneath the milky white surface of the wings has the 

 following marks : towards the posterior margin of the anterior pair, a series of five short brown 

 lines is disposed in an interrupted curve, exterior to which a few faint marginal dots are 

 observed, and a short transverse streak arises near the costa and extends to the middle of the 

 disk ; on the hinder wings the marginal dots of a more intense tint are continued in a regular 

 series along the posterior margin ; the disk is pervaded by a very irregularly curved series of 

 about seven dots, commencing near the anterior margin, the first being disposed in pairs ; three 

 solitary distant dots are placed in the order of a transverse line towards the base. About eighteen 

 dots, in all, may be counted on the lower surface of the posterior wings. Antenna banded with 

 white. Thorax and abdomen agreeing with the adjoining tint of the wings on both surfaces. 

 As far as regards the habit, colour, and contour of the wings, this species agrees with the blues of our 

 nomenclature ; the antennae, however, depart in a small degree from the regular type, and give it a pecu- 

 liar aspect ; the club is strongly compressed and semi-contorted at its base, in consequence of which a 

 swelling appears at the point of union with the filiform portion, which is not usual in this genus. This 

 species is not abundant, and two specimens only are contained in the collection. In its physiognomy and 

 in the distribution of the markings of the lower surface, it resembles the P. Argiolus of the British Fauna. 



3. Polyommatus Puspa. Aim supra maris azurece fusco marginatce, disco albo ; fceminse palli- 

 diores disco cinerascenti-fusco : subtus sericeo-alba, strigis duabus marginalibus serie punc- 

 torum intermedia fascidque maculari discoided fuscis ; posticce, ocellulis pluribus basilaribus 

 nigris albo cinctis duobus margini exteriore approximate, apicali insigniore. (Exp. alar. 1 

 unc. 1 — 4<lin.) 

 Wings above blue with a defined border of blackish brown, and a large white patch on the disk : 

 in the male a deeper tint extends from the base to the edge of the brown margin, varying 

 according to the direction of the light, being either intensely azure or diluted, and transmitting 

 a ground colour of brown ; in the female the blue colour is confined to the base. Underneath
