THE ENTOMOLOGrlST S RECORD. 



We are greatly indebted to Mr. Prout for his kindness in going 

 over and checking these names with the literature on which they are 

 based, and which will be published in due course in the The Natural 

 History of British Butterflies. The names, therefore, we at present 

 propose to use for our British species (we make no note here of the 

 grouping) are as follows : — 



Aricia agestis. 

 Polyommatus icarus. 

 Agriades coridon. 



bellargiis. 

 Cyaniris semiargus. 

 Cupido minima. 



Lampides boeticus. 



Chrysophanus dispar. 

 Rumicia phlaeas. 



Lycaena arion. 



Plebdus argus. 

 Everes argiades. 



Celastrina argiolus. 



Callophrys rubi. 



Ruralis betulae. 

 Bithys quereus. 



Strymon pruni. 



xv-alhum. 



Hamewiis lucina. 



A new hybrid Nyssia: Nyssia hybr. merana. 



By Eev. C. R. N. burrows. 



By a fortunate experiment undertaken in the spring of last year, 

 Mr. A. W. Mera succeeded in pairing a ^ Nyssia zonaria with a 5 

 .Y. lapponaria. The eggs proving fertile, he naturally took special 

 care of the progeny, and was rewarded by the emergence, this spring, 

 of several magnificent specimens of both sexes. As he presented the 

 first male to me, I feel myself more or less called upon to publish the 

 account of the new insect. 



The male presents the appearance of a dark suffused N. zonaria, 

 thus following the rule of resembling the parent of the same sex. 

 There is an entire absence of the orange costal streak on the forewing, 

 so distinct in N. lapimnaria. The wings are not transparent, but well 

 scaled, perhaps a trifle whiter than in N. zonaria. The subterminal 

 line is completely different from that of the male parent, in which it 

 is distinct, unbroken, and direct. In the hybrid the line is distinct 

 enough, but wavy, following the female parent, N. lapponaria. The 

 central lines enclose a darker shade, striking enough, but I have seen 

 iV. zonaria which approach it closely in this way. The hindwings do 

 not show the marginal shade which is so distinct in N. zonaria, but 

 are crossed by two dark lines, only indistinctly marked in N. 

 lapponaria. 



The female hybrid is entirely without the series of orange spots on 

 the central line peculiar to A", lapponaria, the female parent, and is also 

 without the transverse bands of the male parent. The rudimentary 

 wings are perhaps a trifle more developed than in N. zonaria, and 

 about the same as in the case of the female parent. The down upon 

 the abdomen is not very different from that of the female N. 

 lapponaria. 



I would suggest that this insect should be called Nyssia hybrid 

 merana.
