collection as many as 40 species, in the majority of instances new.
One is struck with the small number of species of Phryganeidae and
Limnojshilidae in the collection, and by the predominance of species
of the genus Hydrofisyche, which generally live in slowly-running
water. As many of the localities visited by Fedchenko are exceedingly
elevated, it is difficult to explain the large number of Hydrofisyche
found by him, and the almost total absence from the collection of
Rhyacofihila, which live, as is known, generally near swiftly-running
water.* The examination of the vast materials collected by Fedchenko,
belonging to Trichofitera, cost me great labour. Notwithstanding my
wish to treat in detail as far as possible all the materials sent to me, I
have unfortunately been obliged to leave some species of Trichoptera
undefined and undescribed.
The family Efihemeridae is represented in the collection by about 80
specimens, belonging to the genera Baetis, Cloeon, Hefttagema,
Leftofhlebia, and Centrofitilum. A detailed description of the species
I consider impossible, on account of the specimens being greatly
changed by drying. Katon, who also saw the Turkistan E ‘phcrnerae,
similarly declined to make a description from dry specimens. One
species, the identification of which is certain, is the common European
Lejitofihlebia marginata, L.
Of Psocidae one species of Caecilius, is found in the collection, and
one wingless species, apparently an undeveloped Clothilla.
On taking up the examination of the Neuropt'era collected by Fedchenko,
I foresaw that the Perlidae would present the greatest
difficulty to me, as even the largest European species are yet far from
being sufficiently investigated, not to speak of the multitudinous small
forms. Not having yet decided to undertake a monograph on the
Perlidae of the British Isles, I was very doubtful of my ability to
properly treat those of Central Asia. In the course of time, on a
closer acquaintance with the collection, I quite convinced myself that I
should act very wisely in confining myself to the indication of the
probable number of species in each genus, and only in a few exceptional
cases permit myself to describe certain new forms. Altogether in the
collection there are more than 180 specimens of Perlidae, all belonging
to European genera. The greater portion of the Perlidae collected by
the expedition belong to the genus Nemoura, and to the little-known
allied forms.
Finally, the Termitidae are represented in the collection by some incompletely
developed specimens, which I am not in a position to
determine.
