ON A NEW FORM OF THE GENUS ZYGAINA. 273 
mellus, always plentiful in one chosen locality, were more nume- 
rous than I have ever before seen them; C. pinetellus and 
C. geniculellus also occurred, but in more limited numbers. 
Chareas graminis, Pyralis glaucinalis, and Paraponyx stratiotalis, 
were noticed at light. 
Of the Tortrices, Tortrix viburnana was common; I note that 
its curious females, with their much reticulated and narrow pointed 
wings, are difficult to obtain, although they can be had in plenty 
from larve on Myrica gale. Tortrix lafauryana did not fail to 
occur in its usual numbers, and from a good supply of larve a 
fair proportion of females was secured; for like the former the 
female is scarcely ever seen on the wing. J’. crategana was 
tolerably common, but only found in one wood. Among others 
taken I note Peronea favillaceana, P. schalleriana, P. aspersana, 
Argyrolepia badiana (its allied species, A. cnicana, usually occurs 
annually, but I have not observed it this year), Xanthosetia 
zoegana, Grapholita nisana, E:phippiphora ephippana, E. bimacu- 
lana, Penthina betuletana, and E. dubitana. Dicrorampha politana 
and LH. angustana absolutely swarmed on our heaths.

NOTE ON A NEW FORM IN THE GENUS ZYGANA. 
By W. Prest. 
Durine the last week in July I bred a specimen of the genus 
Zygena, which seemed to me quite different to anything I had 
seen before. I went the next day to where I got the pupe from 
among which it appeared, and by hard work I took six more, 
flying in company with Zygena lonicere. I looked several times 
afterwards, but could find no more lke the particular form I am 
about to describe. When flying they have a rather washed-out 
appearance, and that may account for my not taking them 
before. 
The insect under notice is not quite so robust in appearance 
as Zygena lonicere. The anterior wings look a little more 
pointed than that species; the colour of those wings is steel- 
blue, and they are more sparsely covered with scales than in 
Z. lonicere ; posterior wings and spots pink, not crimson; the 
border of posterior wings is brown, not black ; and the cilia of all
