Y. impluviata, and therefore overlooked; it is mainly dis¬ 
tinguished by its larger size, and the anterior wings being 
more elongated. It is not uncommon in the fens of Cam¬ 
bridgeshire and Huntingdonshire. 
Cheimatobia boreata, Hiibner; the capture of this 
insect in Britain is first recorded by Mr. Cooke in the 
Zoologist for 1850, page 2749—“ Four males of this moth 
were captured at Petty Pool, Delamere, Cheshire, on the 
•31st of October, 1848. They were resting on the trees.” 
In the autumn of 1850 it was taken in great abundance in 
the same locality (Zoologist, 2971), and was liberally dis¬ 
persed by the captors among all our collections. It is at 
once distinguished from C . brumata by being larger and 
paler. 
Oporabia autumnaria, Boisduval; enumerated as Bri¬ 
tish in Doubleday’s Catalogue, at page 18. Its capture is 
recorded by Mr. Weaver in the Zoologist for 1852, page 
3495—“ It rests on the branches of birch. I captured a few 
specimens in Perthshire in 1851, and found it very sparingly 
ln previous seasons.” Mr. Weaver says —“ This species is 
readily distinguished from 0 . neglectata and dilutata. by the 
glossy silver and fineness of the wings, and the slenderness 
°1 the antennas.” For my own part I have never been able 
to Sa tisfy myself that it was specifically distinct from O. dilu- 
taia • Oporabia neglectata , which is also noticed by Mr. 
leaver in the Zoologist at page 3496, and is enumerated as 
a ^tinct species in Stephens’s Museum Catalogue, but I am 
JJ°t aw are that its claim to be considered a species has yet 
een satisfactorily established. 
Oporabia filigrammaria, Boisduval; the capture of 
this 
species in this country was first recorded by Mr. Edle- 
^ on m the Entomologist, at page 356, under the name of 
* P°fata, under which name it is figured and described in 
um Phrey’s and Westwood’s British Moths, vol. ii. page
