Paludina contecta in Nottinghamshire.— During a conchological 

 ramble with my friend Mr. Musson, of Nottingham, this species was found in 

 tolerable abundance in a dyke on the Nottingham side of the river Idle, near 

 Bawtry. On the Yorkshire side we found several shells among the rejectamenta 

 of a small stream. On a previous excursion we collected a number of Balia 

 perversa beneath the loose bark of willow trees growing near the junction and 

 within each of the parishes of Darlton, East Markham, and East Drayton. — W. 

 A. Gain, Tuxford.

Microscopic life at Askern, May 20th, 1886.— I forward a list of 

 the organisms found in the waters about Askern during the Yorkshire Naturalists' 

 Union excursion, as determined after careful examination. Most of the species are 

 common, but of course the state of the water prevented any better kinds being 

 found. Rotatoria: Hydatina senta, Lepadella emarginata, Lindia torulosa, 

 Rotifer vulgaris. Rhizopoda: Amceba diffluens. Entomostraca: Branchipus 

 stagnalis, Canthocamptus minutus, Cyclops quadricomis, Daphnia pulex. Arach- 

 NIDA: Milnesium tardigrada. Hydra : Hydra fusca. Diatomace^: Frustiilia 

 saxonica, Piadesmis confervacea, Diatoma vulgare, Nitzschia sigmoidea, Cymato- 

 pleitra solea, Cocconema lanceolatum, Pragilaria capucina, Gomphonema acuminatum. 

 DesmiDS : Varieties of Closterium, Cosmarium, and Pediastrum. INFUSORIA : 

 Aspidisca lynceus, Amphileptus fasciolus, Coleps hirtus, Dileptus folium, Himanto- 

 phorus charon, Kerona mylitus, Loxodes bursaria, Paramecium aureiia, Sientor 

 mulleri, Trachelocera viridis, Urostyla grandis, Vorticella nebulifera. — J. M. KlRK,

Variation in the Genus Cidaria.— At the meeting of the Entomo- 

 logical Society of London, on May 5th, 1886, Mr. Howard Vaughan exhibited 

 a long series of Cidaria immanata from Kent, Surrey, and other southern counties, 

 Perthshire, Isle of Man, Isle of Arran, the Orkneys, and Shetlands. He also 

 exhibited C. russata from various localities in the South of England, and from 

 Perthshire, Argyllshire, and the Islands of Arran, Lewis, and Hoy. Mr. 

 Vaughan further exhibited varieties of C. suffumata from Dover and Darlington. 

 Prof. Westwood commented on the interesting nature of the exhibition of C. 

 immanata, and stated that he had never before seen such a wonderful collection 

 of varieties of a single species. — Herbert Goss.

Pteromalus puparum near Louth.— In December last I found a 

 chrysalis of Vanessa atalanta on a dead stem of Ballota nigra, by the side of the 

 road at Cawthorpe, near Louth, the inside of which was full of the larvae of a small 

 parasite. These larvae were placed in a chip-box, and on looking at them on 22nd 

 May I found that a large number had become imagines, some of which I sent to 

 Mr. E. A. Fitch, who identified them as Pteromalus puparum. The larvae, which 

 were very inactive, were about ^ of an inch in length and of a dirty white or grey 

 colour. The pupae were about the same length as the larvae, and pale yellowish- 

 brown in colour. Under a low power of the microscope the various parts of the 

 future fly, including the legs, antennas, and wings, could be made out, the segments 

 of the abdomen being marked by lines of a darker colour. One larva, which was 

 kept in a box by itself, pupated on 9th June and remained in that state about 12 

 days. — H. Wallis Kew, Louth, June 22nd, 1886.
