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. XIII. — Notes upon the smaller British Moths, with descriptions of some nondescript or imperfectly characterized species. By John Curtis, Esq., F.L.S. &c. Family ToRTRiciDiE. 1. Genus 946, #*. Tortrix {JEnectra) Pilleriana, Hiib. pi. 27. f. 172 9, and luteolana, Hiib. pi. 21. f. 136, 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 fcetidissima, which abounds at Niton. 2. 28. T. croceana, Hiib. pi. 19. f. 120; Modeeriana, Haw. I took this rare species on 3rd July, 1842, on Bordean-hangers, near Petersfield, Hants. 3. Genus 947, 2. Amphisa Walker ana, Curt, Brit. Ent. pi. 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.*
