Notes on Hemiptera and Mammals. 



names I have not yet determined to my satisfaction. These 

 names I hope to publish in a future communication. 



Hydrachna scutata (Piersig). See 'Science Gossip' for 



August 1900, p. 338. 

 Hydrachna thoni (Piersig). Nymph. 

 Hydrachna biscutata (Thon.). 

 Hydrachna conjecta (Kcenike). 

 Hydrachna sp. not yet determined. 



I know of no English figures of the last four mites yet pub- 

 lished. Like the preceding genus, Hydrachna has been much 

 studied during the last few years, and many species described. 

 In 1842 Koch published his ' Ubersicht ' naming only three 

 species, whilst Piersig in his work, published in June last, 

 describes as certain 33, as uncertain five, and one as a variety. 

 Oxus ovalis (Mull.). 



Hygrobates reticulatus (Kramer). See ' Science Gossip,' 

 October 1899. 



Atax ypsilophorus (Bouz.). I have long been morally certain 

 that this was a Lincolnshire species, but on 5th September 

 last I found two specimens of Anodonta cygnea on the mud 

 at the side of a pond ; one was dead, the other still alive, 

 and in each mollusc I found several specimens of this mite. 

 Its parasitic nature causes it to be seldom observed, but it 

 is common enough doubtless when looked for in the right 

 place. 



NOTE on LINCOLNSHIRE HEMIPTERA. 



Verlusia rhombea at Mablethorpe.— A Bug;, captured on the sand- 

 hills at Mablethorpe a few days ago, has been identified by the Rev. A. 

 Thornier as Verlusia rhombea. L. All the localities for it given by Saunders 

 are south cf London. — C. E. Playll, Louth, 3rd September 1901. 



NOTE on LINCOLNSHIRE MAMMALS, 



White Hares near Horncastle, Line. N.— A white Hare [Lepus 

 europcBus) has been recently shot near here. These are not accidental cases 

 of albino hares, but a strain, which crops up periodically, generally with 

 eyes of the ordinary colour. They are, for the most part, confined to this 

 neighbourhood, but have, at intervals, to mv knowledg-e, been seen for 

 more than thirty years. It is three years, I think, since the last was shot 

 in Tumby Wood. In 'The Field' of nth June 1898, Mr. Fieldsend men- 

 tioned one, which I presented to our Museum at Lincoln Castle, and which 

 had dark eyes. In the same communication he mentioned fifteen other 

 similar instances. — J. Conway Walter, Langton Rectory, Horncastle, 

 14th October 1901.
