Notes — Trichoptera and Mollusca. 



(Homoptera). Galerucella viburni. 



Philsenus spumarius. Adalia bipunctata. 



Aphrophora salicis. Apoderus coryli. 



Aphrophora alni. A pio n subulatum. 



Meligethes rufipes. 

 Coleoptera. Crepidodera aurata. 



Coccinella 7-punctata. Plectroscelis concinna. 



The Spiders and Harvestmen were as follows : — 

 Xysticus ulmi Hahn. Epeira diademata C.L.K. 



Xysticus lanio C.L.Koch. Linyphia insignis Bl. 



Linyphia triangularis C.L.K. Linyphia montana C.L.K. 



Lycosa annulata Thor. Philodromus dispar Walck. 



Tibellus oblong-us Walck. Olig-olophus morio Fabr. 



Meta segmentata C.L.Koch. Oligolophus agrestis Meade. 



Cyclosa conica Meng'e. Lioburnus rotundus Latr. 



Pachygnatha listen Sund. Phalangium cornutum Linn. 



The hospitality was on a lavish scale, Dr. Lowe paying for 

 the carriages and all expenses, and providing an admirable 

 string band to add enjoyment while discussing his viands. It is 

 needless to say the vote of thanks the Rev. Canon Rowe moved, 

 and Mr. B. Crow seconded, met with more than the usual 

 warmth of reception. 



NOTE— TRICHOPTERA. 

 Leptocerus dissimilis near Lincoln. — Among some insects taken by 

 me at Sudbrooke, near Lincoln, on the 21st May 1898, is one, Leptocerus 

 dissimilis, which Mr. G. T. Porritt has determined, and states is ' rather 

 a good species, but the only one of interest among- your specimens.' — 

 J. Eardley Mason, Lincoln, 17th May 1900. 



NOTE-i-LAND AND FRESHWATER MOLLUSCA. 

 Pisidittm amnicum, etc., at Saltfleetby, Lincolnshire. — During 

 a brief visit to Lincolnshire, in April, I had the pleasure of accompanying 

 my brother on a walk, occupying the greater part of a day, from Saltfleetby 

 to the sea, and thence to Saltfleet and Donna Nook and back. Among 

 weed which had been thrown out of the great drain along the left of the 

 road at Saltfleetby we found dead shells of Pisidium amnicum and 

 Spheerium lacustre v. brochoniana, two forms of Pelecypoda which we had 

 not previously collected in Lincolnshire, and which are additions, as far as 

 the north of the county is concerned, to Mr. Roebuck's list of the land and 

 freshwater Mollusca of Lincolnshire, published in 'The Naturalist' in 1887. 

 The water in this drain was in places very clear, and we could see, as of 

 old, the bulky and lethargic Viviparus Contectus on the mud at the bottom 

 in some abundance. We were not provided with a scoop, and thus could 

 not ascertain whether Segmetitina nitida ( = Planorbis lineatus) was still 

 living in its old habitat in the dikes on the right of the road ; we saw in 

 these dikes, however, still in Saltfleetby, Bythinia leachii, Pla?wrbis corneus, 

 Planorbis contorhts, Limncea pahistris, etc. For the rest of the walk we 

 saw nothing of note, except that among the dead shells of Helix nemoralis, 

 which were very numerous on the sandhills and warrens at Saltfleet, we 

 found one little group all smaller than usual, and of these two or three had 

 the spire considerably raised. I am indebted to Mr. J. W. Taylor for 

 the varietal name of the Spheerium above noted. — H. Wallis Kew, 13th 

 May 1900.
