Stai?itonianc. may be found, and is possibly not uncommon, but 

 owing to the comparative rarity of suitable weather at that alti- 

 tude, is not often taken. It occurs always amongst Vaccitiium 

 myrtiiliis, and has clearly no connection with Ardostaphylos uva- 

 nrsi, on which plant the larva was at one time supposed to feed. 

 On Ben Chat the alpine Sericoris irrigiiana has been taken, while 

 the commoner S. cespitana occurs in the glen itself. The hand- 

 some Peronea 77iaccana has been taken by Sir T. Moncreiffe, 

 amongst its favourite Vacciniu7n Vitis-Idcea. On Craig Urrard, 

 near the mouth of the glen, the larvae of Euchromia flanwieana^ 

 and of the rarer Coccyx finitimana, may be found on the bear- 

 berry : the Coccyx also occurs at the back of Ben-a-Ghlo. Cne- 

 phasia lepida7ia is only worth noticing from the fact that, in ap- 

 parently suitable places in the more lowland parts of Perthshire, 

 it does not occur, while abounding in many parts of the High- 

 lands, such as Rannoch and Glen Tilt. The great prize in this 

 family in Glen Tilt is the beautiful silvery-white Ablabia argentaita, 

 which we were fortunate enough to discover (for the first time in 

 Britain) in 1875. Till last season we thought that this moth was 

 entirely confined to one very small spot, where certainly its head- 

 quarters are ; but we have since seen it extending over about a 

 mile of the glen, or more. When flying about the grass it is very 

 conspicuous. Its flight is short, and from its habit of settling on 

 the stems of the grass, it is easily seen and taken — though, from its 

 pure colour, perfect specimens are rather scarce. On the hillside 

 above Forest Lodge, at an altitude of from 1600 to 1900 feet, 

 Phoxopteryx hmdana, which otherwise is, in Perthshire, a not very 

 common lowland species, occurs, along with P. myrtillana^ which 

 ascends still higher. Another scarce Perthshire species, Olindia 

 ulmana^ has been taken near Blair Castle. By far the most com- 

 mon species of this family in the glen is Dicrorampha herbosana, 

 which abounds in grassy places near the Tilt. 



Of the Tineiiia I cannot say very much, though many interest- 

 ing species occur. The Lapland form of Tinea riisticella, known 

 as var. spilotella, has been taken on Ben Chat, along with the 

 usual form, while Teichobia verhuellella, which is one of the ^qw 

 British Lepidoptera that live upon ferns, was taken by Mr Herd 

 near the Falls of Fender. Incurvaria oehlmanniella we find very 

 rarely amongst Vacci?iiti??i, above 2000 feet — a curious place for 

 rather a rare insect. Another insect not often found so high up 

 is Plutella cruciferaruTn. This I have seen on other hills, and 

 think that some other plants besides Cruciferce must be eaten by
