vitisella from the Sheffield district. In the Middlesbrough district 
a good many specimens were noted on one or two occasions in June, 
among the best being Stigmonota dorsana and S. interiiana^ Adela 
riijiinitrella^ and Coleophora fahriciella^ and during the season a 
good many other species which are not as yet identified were taken. 
Neuroptera and Trichoptera — Mr. G. T. Porritt writes : — 
Very little work has been done among the Neuroptera and 
Trichoptera during- the year. The only things worthy of record 
are the finding of Hemerohius marginatiis commonly at Arncliffe, 
on the occasion of the Union's Excursion there, on August 3rd, 
by myself ; and the still more local Hemerohius orotypus in abun- 
dance in the Grass Wood, Grassington, on September 7th, also 
by myself. Chrysopa tenella was common at Huddersfield ; and 
Mr. W. Denison Roebuck found the curious Clicetopteryx villosa at 
llkley.

and W. Hewett. 
The ConGllOlOg*ical Section was officially represented, 
and the officers report that good work was done at all the 
Excursions except the one at Horton-in-Ribblesdale. At the 
opening meeting at Robin Hood's Bay no terrestrial forms were 
looked for, the whole attention of the members of the section 
present being devoted to the search for marine mollusca between 
tide-marks, about 34 species being observed. 
In respect of land and freshwater mollusca, about a dozen 
species were noted at South Cave, space and time being restricted 
to a very limited area of park and wood and a couple of hours ; at 
Thorne Waste, or rather in its vicinity, 30 species occurred, only 
one of \h^vci—Hyalinia alliaria — being found on the Peat Waste 
itself ; and in Littondale about 30 species were collected or noted. 
The results of the Littondale Excursion were particularly 
interesting, the district not having been visited by conchologists 
for more than thirty years, and the results achieved, and the 
comprehensive and complete manner in which the dale and its 
mountain-barriers were investigated, demonstrate the wisdom of
