examined the evidence in support of these changes, and is not disposed to 
consider Wallengren’s identifications as proved. 
Small Trichoptera (and insects of some other Orders) may be preserved 
in a condition most suitable for study by blowing open the wings when 
freshly pinned, so as to separate these from each other, and from the 
abdomen, allowing them to dry in that position. McLachlan, Ent. M. M. 
xvi. p. 45, Ent. Nachr. v. pp. 199 & 200. 
McLaciilan calls attention to a habit certain species of this group have 
of depositing their eggs, enveloped in the usual gelatinous medium, on 
the leaves of trees far from water, in autumn. The young larvae pro- 
duced from these eggs appeared to belong to the Limnojihilidai, and 
probably to the genus ITalesas. Ent. M. M. xvi. p. 135. 
The larvae to which F. A. Forel attributes the cause (in part) of the 
sculptures on limestone pebbles on the shores of Lake Leman [c/. Zool. 
Rec. XV. Ins. p. 247], proved to pertain to Tinodes toceneri, L. (= lurida^ 
Curt.). Similar sculptures are very abundant on the pebbles of the 
shores of Lake Neuchdtel, and are probably due to a variety of causes.

Ilelicopsyche sperata, McLach. A full account of the habits and struc- 
ture of this species is given by Ph. de Rougemont in Bull. Soc. Neuch. 
xi. pp. 405-426, with plate. A previously read note by him appears in 
Verb. schw. Ges. 1878 (1879), p. 138, in which he proposes the name H. 
fanniy subsequently dropped. Notes on De Rougemont’s discovery, by 
McLachlan, are published in Ent. M. M. xv. pp. 239 & 257, and his paper 
is reprinted almost in extenso, with notes, by Yon Siebold in Bull. Ent. 
Ital. xi. pp. 134-138, under the title, “ 11 Ilelicopsyche in Italia ; Lettera 
terza agli entomologi Italiani.” Targioni-Tozzetti, Resoconti Ent. Ital. 
1878, pp. 28-31, announces the discovery of the female insect by Tassi- 
nari at Imola, and gives a woodcut of it, with detailed description, &c. 
In the same Resoconti for 1879, pp. 18 & 19, he states, on McLachlan’s 
authority, that the insect referred to was Tinodes aureola^ and not Heli- 
copsyche ; notes on the structure of the male are there given. 
Fritz Muller states that about half-a-dozen species of Ilelicopsyche 
are known to him as occurring in South Brazil. One species is very 
remarkable for the first-built portion of the case being straight, so that 
it remains like a small chimney on the top of the more adult cases. One 
species inhabits rocks wetted by the spray of waterfalls, and is more
