THE YOUNG NATURALIST.

which is, var. " Thules ? " the very dark ones, the smoky ones, or the dusky 

 form ? Dark. 



Montanaria, — All small, like Welsh specimens from Llanferres, but with 

 richer reddish filling in. Dark. 



Immanaria.— Only one poor specimen. 



Eudorea angustalis. — Yery light, like Welsh specimens from Ehyll Llan- 

 dudno. Light. 



Dalella.—Like English specimens. The Tinea he brought do not vary, 

 cladiella being the best species taken. 



Munitaria. — Yery fine, varies a little from the Scotch form, some specimens 

 being smoky looking, Dark. 



Didymaria. — Dark males, very light, large females. Half. 



Fluctuaria. — Large, dark. Dark. 



Cossiaria, — Many very dark, many banded forms, and many light specimens 

 were brought ; varies little from Lancashire, Yorkshire, and Welsh forms ! 

 Herein consists the value of an independant amateur entomologist's collec- 

 tion over that of a Dealer's collector, who might only bring the variable forms, 

 and so we might jump to the conclusion on seeing his collecting boxes that 

 all the specimens he saw were varieties. 



C. musculana. — A long series, exceedingly variable, but all bright silvery 

 light-grounded specimens. Light. 



No specimens of cursoria, hyperlorea or conspersa were taken, but 

 the larvse of conspersa and venosata were sent to me from Unst by 

 Parcel Post, feeding on the seeds of Silene maritima. and are now in pupa. 

 When they appear I may write my observations thereon. In the meantime 

 I think we may sum up that out of eighteen or twenty species captured 

 during the short Shetland summer by Mr. Curzon, when compared with 

 English and Scotch specimens nine or ten are lighter, or as light as ours, 

 and eight or nine are darker. Whilst one or two species are doubtful either 

 way, venosata is like the Manx specimens in colour, but less in expanse. 

 Whilst Eupetliecia Curzonii is like nothing else I know, except, perhaps, a 

 young naturalist might mistake it for Phibalapyterx lineolata in marking and 

 shape, but it is a more delicate and silvery. looking insect. Its greatest 

 peculiarity is that hardly two specimens are alike, and very often its two 

 wings differ in markings, it varies from light silvery lineolate to dark banded 

 specimens, often with a broad well pronounced central band, cut up with 

 two faint silvery lines, which follow the shape of the striga they are in.
