BUTTERFLIES OCCURRING IN ST. PETERSBURG. 183 



specimen is somewhat similar to the variety of the species known 

 as charlotta, and referred to by Westwood and Humphreys as 

 follows : — 



''Pap. charlotta of Haworth (Lep. Brit., p. 32; Sowerby, 

 Brit. Misc., pi. 11 ; Bree in Loudon's Mag. of Nat. Hist., v., 150: 

 Arq. charlotta, Jermyn), represented in our plate 12, figs. 1-2, is 

 regarded by Stephens and Curtis as a var. of this species 

 (A. aqlaia), differing from it in having two of the costal spots on 

 both sides of the fore wings united, and only nineteen instead of 

 twenty-one silvery spots on the under side of the hind wings, 

 several of the ordinary spots at the base being confluent." 



ON SOME BUTTERFLIES OCCURRING IN THE 

 GOVERNMENT OF ST. PETERSBURG. 



By Boris M. Menshootkin. 



In the 'Entomologist' for January last {ante, p. 1) Mr. South 

 figures and describes a variety of Argynnis eiiphrosyne, and it 

 may therefore be interesting to record a similar variety of A. 

 selenc taken by myself in the Government of St. Petersburg. 

 On the upper surface the fore wings are of the same brown colour 

 as in typical A . selene, but tinged with grey-brown at the base ; 

 the discoidal cell has two yellow-centred black spots, one at the 

 outer end and one some three millimetres from it, but not quite 

 in the middle of the cell ; the submarginal area in the lowest 

 part has three distinct spots, of which the first two are elongated 

 and have the appearance of arrow-heads, the others are merged 

 together and indistinct ; the marginal line is black, with black 

 dots on the nervules uniting in the upper part with the sub- 

 marginal line, and enclosing spots of yellow between the nervules. 

 Hind wings: basal area almost wholly black, the centre is clothed 

 with black hairs, and all the nervules are black, some broad and 

 diffuse, others finer and sharper ; between them is a row of black 

 spots uniting with the nervules, and giving the appearance of a 

 black transverse band. Under surface similar in many respects 

 to that of typical A. selene, but there are no black patches on the 

 outer margin of fore wings : on the nervules the yellow deepens 

 only to greyish brown, and slight yellowish grey patches are seen 

 on the submarginal row of dots ; the marginal'line itself is black, 

 very thin and distinct : hind wings have the nervules very sharply 

 defined; the outer marginal area looks faded, and there are little 

 patches of brown on the nervules forming a submarginal band 

 interrupted in the middle. 



So far as I know, this form of A. selene has not been pre- 

 viously described ; it appears to be very local, and certainly has
