NOTES ON THE INSECTS OF STRATHGLASS, INVERNESS-SHIRE. 
BY F. BUCHANAN WHITE, M.D. 
In the summer of 1869, I paid a visit to Strathglass ; and, as this 
district is almost unbroken entomological ground, an account of its 
insect-fauna may be interesting, and will, I hope, induce some adven- 
turous collector to turn his back on Rannoch and explore further this 
productive glen. Should any one meditate a ‘visit to Strathglass, I 
shall have much pleasure in assisting him with any information as to 
localities. &c. 
Strathglass ‘the “grey valley ”’) lies parallel to, and north of, the 
chain of lochs that form the Caledonian Canal, and begins a little to 
the west of Beauly. It is about’ 1S miles in length, and has on its 
north side three tributary valleys, which run nearly parallel to it. These 
are Glen Strathfarrar, Glen Cannich (the “ valley of cotton grass’’), and 
Glen Affrick (the “ valley of greyish water’’), the last being a continua- 
tion of Strathglass and of about the same length. All the valleys are 
narrow and bounded by high hills, whose lower slopes are covered in 
many places with forests of birch and pine. At the top of each glen 
the mountains attain their greatest height—one of the highest being 
Mam Suil (the “ rounded hill of the eye,” z. e. of the extensive view,) 
near the top of Glen Affrick, and about 3800 feet in height. 
Fasnakyle (the “growing of the trees”), where my quarters were, 
is situated near the opening of Glen Affrick, and in some extensive 
birch woods; and my principal collecting ground was an area of one 
mile long by three broad—one mile along the river and three up the 
hills. The lowest part of this area was about 200 feet above the sea, 
and the highest about 2500 feet. Within this space almost all the 
species I captured in Strathglass occurred. A short description of the 
vegetation within this area will give an idea of a productive collecting 
ground in the Highlands. In the lower parts are woods of birch mixed 
with sallow, alders, and a few aspens, the undergrowth being heather, 
bilberry, with bracken and other ferns, and the whole surface of the 
ground rough and broken in the extreme, here rising into rocky hillocks, 
there cleft by the winter torrents—-one of my sugaring rounds, by the 
way, being up the not-always-dry bed of one of these torrents. Here 
aud there are marshy glades fragrant with bog-myrtle, and leading from 
one marsh to another are narrow deep natural ditches, often quite con- 
cealed by heather, and forming nice traps for the unwary collecter: more 
than once it was my fate to find suddenly one leg immersed in a couple of 
feet of ice-cold water, while the other remained high and dry, a sensa- -
