Yorkshire Natiiralisis at Spurn. 



barren, but now was alive with Helix nemoralis and aspersa, 

 both beautifully banded and marked ; some of the specimens 

 havings interrupted and cross banding- very marked. The speci- 

 mens were very fine and large, both of yiemoralis and aspersa. 

 Mr. Pawson also took H. -iiemoralis and aspersa at Spurn Point, 

 and said the Point swarmed with them. 



We found but few Helicella virgata, though they are said to 

 abound. One specimen of Helix hispida was taken. The only 

 record for slugs was the common Agriolimax agrestis, and 

 there were few of these. Returning by road to Easington, the 

 brackish streams yielded plentifully Paludestrina ventrosa. The 

 ponds in the neighbourhood of Kilnsea yielded nothing, maybe 

 because there seemed an abundance of good collectors in the 

 shape of geese and ducks. But a small pond about a mile out 

 of Easington, covered with duckweed, yielded Lijrmcea peregra, 

 Planorbis albiis, and Sphceriitm corneiifii. 



There were several very fine Thrushes' altars, one of which 

 was photographed by Messrs. Fortune and Bingley. 



Considering the dryness of the weather for some time and 

 the shortness of the time at our disposal we consider we did 

 very fairly. 



For Lepidoptera Dr. E. O. Croft reports : — The conditions 

 were not very favourable for work in this department. Stormy 

 weather on 2nd July and a rather strong breeze on the following 

 two days did not allow of many insects being seen on the 

 wing. Among the butterflies noticed LyccEna icarus [Alexis) 

 was common and in fine condition ; Hipparchia janira was 

 abundant, and H. tithomis was seen near Easington. In the 

 same district also H. hypera7ithiis was taken. The Common 

 Whites were unusually scarce, a few Pieris napi and one 

 P. Brassicce being the only ones seen. Common species of 

 Geometrae were fairly abundant, especially Melanippe montanata, 

 which was present in every hedgerow. Larvae of Eiichelia 

 jacobecE occurred commonly on ragwort on Kilnsea Warren 

 and near the Spurn Lighthouse, a profusion of the cocoons and 

 recently emerged imagos of Zygcena filipendulce were noted. 

 Ova and the female imago of Odonestis potatoria were also 

 found on the Spurn. Owing to the distance from headquarters 

 no night collecting was undertaken. 



Mr. Ostheide has identified the following species of coleop- 

 tera brought by Dr. Croft : — Creophiliis maxillosus L. and 

 Necrophorus ruspator Er. {investigator Zett.).
