not common in either of the other two, although many are asym- 
metrical in this respect. 
The larve of £. helveticata were beaten out of the juniper along 
with those of juniperata ; but so close was the resemblance between 
the two that I did not discover the fact till I reached home. 
Larvee of Bupalus piniaria were common. When dislodged they 
hung from the tree by a silken thread, but never fell to the ground. 
I think they must both rest and feed ready attached, for they were 
never taken by surprise, however suddenly the blow was given. 
Of micros I can give but a poor account. I was unsuccessful 
in obtaining many species that I know occur in the locality. I took 
only twenty-four species. Of the Pterophori, 1 ; Crambi, 1 ; Yortrices, 
15; liner, 7. Pedisca ophthalmicana and Tachyptilia populella 
were very abundant wherever the poplar was found, and I obtained 
some very nice forms. Lphippiphora similana was most local, being 
confined to a few square feet of scrub birch at a high elevation. By 
climbing to the locality day after day for a week, in all weather, 
I succeeded in getting two dozen, never more than three or four at 
a time. 
The total number of species taken was fifty-six, including Rhopa- 
locera, 4; Noctuz, 14; Geometre, 14; Pterophori, 1; Crambi, 1 ; 
Tortrices, 15; and Tine, 7. 
To those who go to Aviemore for collecting purposes I would 
recommend from ist of June to end of July as being the cream of 
the season.
