210 YORKSHIRE NATURALISTS’ UNION AT ROKEBY. 
for by the fact that the time at their disposal was very limited, and 
that the weather was extremely fine, and hot, and the ground very dry 
and hard. Only three Freshwater species were found, none of which 
were of special interest. Of the Slugs seven species were recorded, 
amongst which Avion minimus, the latest addition to the British List, 
may be noted; this evidently will prove to be widely distributed, having 
been also found on the previous excursion of the Union to Horton-in- 
Ribblesdale. The Land Shells were represented by twenty species, 
which must be considered rather poor work, more especially as this 
number was made up of the commoner and most widely distributed 
forms, the only exceptions being Ae/ix sericea and Balia perversa. 
Meagre as the list is, it would have been more so but for the exertions 
of Messrs. Gelderd and Lofthouse. The complete list of species 
taken is as follows :— 
Limnea peregra. Vitrina pellucida. Helix rotundata. 
Limnza truncatula. Zonites cellarius, Bulimus obscurus. 
Ancylus fluviatilis. Zonites alliarius. Pupa umbilicata. 
Arion ater. Zonites nitidulus. Balea perversa. 
Arion hortensis. Zonites purus. Clausilia rugosa. 
Arion .circumscriptus. . Zonites crystallinus. Clausilia rugosa var. 
Arion minimus. Helix nemoralis. ubia. 
Limax maximus. Helix hortensis. Clausilia laminata. 
Limax agrestis. Helix arbustorum. Cochlicopa lubrica. 
Limax arborum. Helix hispida. Carychium minimum. 
Succinea putris. Helix sericea. 
The report of the Entomological Section was read by Mr. Jas. H. 
Rowntree, one of the Secretaries of the section, and the following 
account is supplied by his colleague, Mr. A. E. Hall, F.E.S.:— 
The time at the disposal of members on the Monday being so short, 
and quite insufficient to do justice to the locality, we decided to 
make a longer stay in the district, and now include the insects 
noticed during our stay at Greta Bridge from Friday night, June 3rd, 
to Tuesday morning, the 7th. The locality appears to be a go 
rch elm i 
taken so no 1 
else this appeared a suitable locality, though repeated beating 
produced no larve'of this species. Xanthia ferruginea larvee were 
numerous, and it is probable that X. gi/vago was taken also. 
The usual spring larvee, such as H. progemmaria, H. defoliaria, etc., 
were common, and C. brumaéa a pest, as usual. No other larve 
worth recording were noticed. Sugaring was a complete failure, not 
attracting a single insect. The following is a complete list of the 
imagines taken or seen, all of them in the immediate neighbourhood 
of Eggleston Abbey and Greta Bridge :-—
