Trichoptera. 
McLachlan, Robert. A Monographic Revision and Synopsis of the 
Trichoptera of the European Fauna. Part vii. pp. 349-428, pis. 
xxxviii.-xliv. (June, 1878). London and Berlin : 8vo. 
Occupied by the Hydropsychidce (with which the (Estropsidoe arfe 
united). As in former Records, only the new genera and species are 
here noticed, in consequence of the intricacies of synonymy. 
Fritz Muller gives notes on the cases of various Brazilian species in 
anticipation of a more extended memoir on the subject, and calls atten- 
tion to the homology existing between the wing-nervures of Trichop- 
terous insects and those of Lepidoptera ; P. E. Soc. 1878, pp. Iv.-lvi. 
Additions to the species found in the Clyde Valley; F. G. Binnie, 
P. N. H. Soc. Glasg. iii. p. 258. 
Indusia calculosa, Scudder, Bull. U. S. Geol. Surv. iv. p. 542. This 
name is proposed for certain fossil caddis- worm cases from Wyoming, con- 
sidered to be analogues of those found in the Indtisial Limestone of 
Auvergne, and possibly belonging to the Limnophilidm. 
Limnophilidoe.

vicinity ; Taschenberg, Z. ges. Naturw. (3) iii. p. 344.

Hy dropsy chidce. 
R. McLachlan (Revision and Synopsis, pt. vii.) describes 73 species as 
belonging to the European fauna, and figures details of all (with one or 
two exceptions). He divides the family into five sections as follows : — 
1, equivalent to the family CEstropsidce of Brauer, perhaps scarcely dis- 
tinct from 2, which includes Macronema and allies ; 3, consisting of the 
single genus Hydropsyche ; 4, Philopotamus, Folycentropus, and allies ; 
6, Tinodes^ Psychomyia, and allies. 
F. A. Forel attributes certain sculptured markings on the limestone 
pebbles on the shores of Lake Leman to the action of the larvae of some 
species of this family ; Bull. Soc. Vaud. (2) xv. Proc. verb. p. 29.
