O. excavata. land’s End, Mr. Barlee ; Exmouth, Mr. Clark, 
who notices that his specimen has “a strong conspicuous fold or 
tooth about the middle of the columella.” 
O. scalaris var. a. This is proposed to be distinguished by 
Messrs. Forbes and Hanley as the typical species, the name of 
rufescens being appropriated by them to the other species or va- 
riety. I however believe the latter to be only a northern form 
or variety. 
O. lactea.- Guernsey ; Burrow Island ; Mr. Barlee. 
The variation of form in many of the species appears to be 
very considerable ; and it would be easy to add several others to 
the list. 
XIII1.—Notes upon the smaller British Moths, with descriptions 
of some nondescript or imperfectly characterized species. By 
Joun Curtis, Esq., F.L.S. &e. 
Family Torrricip2£. 
1. Genus 946, 4°*. Tortria (Ainectra) Pilleriana, Hib. pl. 27. 
f. 1729, and luteolana, Hib. pl. 21. f. 186, is a very variable 
species, and differs from the other Tortrices in the form of the 
palpi. Several specimens were taken by W. W. Saunders, Esq., 
at the back of the Isle of Wight. The larva lives principally upon 
the vine, and is very destructive in the vineyards of France, but 
it will feed also on Stachys germanica, and in the capsules of Iris 
fetidissima, which abounds at Niton. 
2. 28. T. croceana, Hib. pl. 19. f. 120; Modeeriana, Haw. I 
took this rare species on 8rd July, 1842, on Bordean-hangers, 
near Petersfield, Hants. 
3. Genus 947, 2. Amphisa Walkerana, Curt. Brit. Ent. pl. 209. 
In the summer of 1827 Mr. H. Walker took two males of this 
curious little moth near Lanark, which I described and published 
the following year, and he afterwards saw it flying in some abun- 
dance over heathy districts, the end of March, in the sunshine 
about noon, on Tinto, a hill near Lanark. 
__* As great confusion often arises for want of references to some access- 
ible work, the numbers of the genera and species of Curtis’s Guide, 2nd ed., 
have been added, as well as those of the ‘ Brit. Ent.’
