92 LEPIDOPTERA. 



the leaves o^ Potentilla Tormentilla amongst the heather on 

 Birnam Hill, Dunkeld, in September, 1859, and I had 

 assumed, without hesitation, this would have been the Tor- 

 mentUlella of Herrich-SchafFer, but it is totally different. 

 Herrich-Schaffer's insect has the anterior wings metallic- 

 greenish at the base, the fascia silvery, slender and slightly 

 curved; ray specimen has the base of the anterior wings 

 brownish, the fascia is pale golden, rather broad, and nearly 

 straight. It would be unsafe to found a species on this sing^le 

 specimen, but it is not improbable that more than one species 

 may feed upon the Potentilla Tormentilla. 



Of Nepticula Ulniivora no specimens have been yet bred 

 in this country, and therefore it would be hazardous to assume 

 with certaintij that the larvas which we take for those of that 

 species are really referable to it. These larvas have been col- 

 lected by Mr. M'Lachlan and myself, between Norwood and 

 Addincirton.
