devoniella, which appears to be still unique, differs from this species in having the 

 whole fore-wing fuscous ; but the German Entomologists doubt whether it is truly 

 distinct. 



While fishing in Sutherlandshire this year in May, I came across a Nep- 

 ticula, which Mr. Warren pronounces to be the Nt/landriella of Tengstrom. It 

 occurred in some numbers on the trunks of mountain ash trees in one wood, and 

 may probably turn out to be more generally distributed. It is a very minute species, 

 measuring from ly to 2^'" across. The following description from Heinemann, 

 given me by Mr. Warren, is so good that I cannot do better than copy it. 



"Fore-wing narrow, ashy-bronze, shining: head yellowish: frontal tuft of (J 

 brown, of ? pale ochreous : antennae short, whitish-gi'ey : eye-caps silvery-white : 

 fore-wing very smooth as though polished, pale silvery-grey, witli a faint yellowish 

 tinge : apex scarcely darker, with a faint violet gloss : cilia whitish-grey, rather 

 darker towards their base." 



The only point which seems to need correction is that the head appears to be 

 only sometimes yellowish, and that more frequently in the females. The males 

 usually have heads the same colour as the fore-wings. — A. F. GtHIFFITH, Sandridge, 

 St. Albans : June 2iHh, 1885. 



P.S. — Since writing the above, Mr. Warren has informed me that XylandrieUa 

 (Tng.) and aucuparice (Frey) may possibly prove to be identical. If so, Frey's de- 

 scription (" very like viscariella ") would appear to be entirely misleading, unless 

 the species (with me very uniform) in other localities shows considerable variation. 



On the occurrence of Trifurcula pallidella near St. Allans, Herts. — While 

 collecting Bichrorampha acuminatana near here in 1883, I took two specimens of 

 this species running up grass-stems in a piece of waste ground covered with mixed 

 herbage. I was unable to identify it until the day of Mr. Harper's sale, when Mr. 

 Warren, on seeing one of them, immediately guessed the species ; and Mr. 

 Hodgkinson, who happened also to be in the sale-room, confirmed his surmise. He 

 informs me that with the exception of the one specimen he took near Preston, the 

 insect has hitherto only been met with near Yienna. One of my specimens is a very 

 fine one, the other but poor. The species, which measures about 4'" across, is 

 unicolorous, nearly white ; and may be immediately recognised by its very rough 

 head. I have twice been to the same spot since, but have been unable to find any 

 other specimens. — Id. 



On the larvce of Coccyx tcedana and Euchromia Jlammeana and arbutana. — 

 I met with the larva of tcedana somewhat commonly on Arctodaphylos uva-ursi 

 this May in Sutherlandshire. It mines the leaves, and as soon as it has finished 

 one it eats a round hole through the skin, fixes another leaf to it, eats its way into 

 it and clears that out, passing on to another when necessary. It turns to a pale 

 yellow pupa in one of the hollowed-out leaves. The larva is pale yellowish, very 

 transparent, with dark head, and appears to be very subject to ichneumons. I have 

 also bred aflam^neana and several arbutana from the same food-plant ; the larva 

 of the latter is slightly hairy, blackish, and spins together the terminal leaves of 

 the shoots much in the same way as dimidiana does on Myrica gale. — Id.
