THE YOUNG NATUEALI8T. 



rufipes in the flowers of a primrose, we arrived at a small quantity of clear 

 water, in which the little water-beetle (Eydroporus palustris) was seen, and 

 Limncea truncatula appeared to be plentiful on the mud at the bottom. 

 Presently a pond was reached, on a log of wood in which were two specimens 

 of Helophorus aquaticus, and on the surface of which whirlwigs (Gyrinus 

 natator) were swimming. At length we arrived at Grisel-bottom. Here we 

 reclined upon a dry bank, with a good view of this beautiful post-glacial 

 valley, to lunch — the scene was a lovely one, the mid -day sun was shining as 

 brightly as it could do, considering it was yet only April ; the air was full of 

 small insects, representing various orders ; near our feet a humble-bee fly 

 (Bombylius medius) was hovering over the primroses, and a few yards before 

 us was a large patch of Viola hirta in full flower. The following coleopterous 

 insects were seen flying in the sunshine in this valley : Helophorus aquaticus, 

 Sitones lineatus, Hypera nigrirostris, Meligethes rufipes, Anchomenus parum- 

 punctatus, and Silpha thoracica. Under a prostrate branch Clausilia lami- 

 nata and a very young garden slug {Arion hortensis) were found. On the 

 ground in the bottom of the valley dead and bleached shells of Cyclostoma 

 elegans and Cochlicopa lubrica were picked up. Meligethes rufpes was com- 

 mon in the flowers of Poteniilla /ragariastrum. 



On leaving Grisel-bottom, we walked through Haugham Wood in a home- 

 ward direction. We searched for shells under a fallen tree, which Mr. W. 

 D. Eoebuck, Editor of the " Naturalist," during his stay in Lincolnshire had 

 examined only a few days previously ; here we found Zonites glaber, Z. crys- 

 talline and Helix rotundata. Carychium minimum was found under this 

 tree by Mr. Roebuck. Going a little further a group of several prostrate 

 trees produced Zonites glaber, Z. purus v. margaritacea, Helix rotundata 

 and Limax Icevis. A specimen of the lady-bird. {Coccinella variabilis) was 

 also noticed. On turning over another prostrate tree about a dozen speci- 

 mens of Clausilia laminata and several C. rugosa were found. Leaving 

 Haugham Wood a little time was spent in Maltby Wood, Arion subfuscus 

 being found under a log. 



On Saturday, the 1st May, Mr. Y. T. Crow, one of the members of the 

 " Louth Naturalists' Society/' and myself left Louth for the woods, at 

 2 o'clock in the afternoon. Leaving Maltby Wood behind, we visited a 

 wood known as " Haugham Pasture " first of all. By the roadside near the 

 wood Zonites glaber, Helix rotundata, H. hispida, and Limax agrestis type 

 and v. sylvatica were noted under a log. In Haugham Pasture a small pros- 

 trate hawthorn trunk was turned over, Clausilia laminata, Helix rotundata, 

 Zonites glaber, and fitrina pellucida were noticed, and seated on the bark 

 on the under side of the trunk was a single specimen of Barynotus maerens,
