NEW BRITISH SPECIES SINCE 1835. 41 



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 motb 

 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 

 in previous seasons." Mr. Weaver says — " This species is 

 readily distinguished from O. neglectata and dilutata by the 

 glossy silver and fineness of the wings, and the slenderness 

 of the antenna?." For my own part I have never been able 

 to satisfy myself that it was specifically distinct from O. dilu- 

 tata. Oporabia neglectata, which is also noticed by Mr. 

 Weaver in the Zoologist at page 3496, and is enumerated as 

 a distinct species in Stephens's Museum Catalogue, but I am 

 not aware that its claim to be considered a species has yet 

 been satisfactorily established. 



Oporabia eiligrammaria, Boisduval ; the capture of 

 this species in this country was first recorded by Mr. Edle- 

 ston in the Entomologist, at page 356, under the name of 

 O. polata, under which name it is figured and described in 

 Humphrey's and Westwood's British Moths, vol. ii. page
