genus. In 1909, I took two specimens at Strathfieldsaye, Hants, with the elytra 

 as dark as in M. pulla, and with the posterior angles of the thorax only 

 obscurely reddish. They occurred in a starling's nest in company with the 

 ordinary form. This variety is of course easily distinguished from M. pulla and 

 M. nidicola by the much finer punctuation of the thorax, and from small 

 specimens of M. gentilis, which it more closely resembles, by the thorax being 

 alutaceous between the punctures. — Norman H. Joy : April, 1912. 



Haematopinus {Hsemodipsus, Enderlein) ventricosus, Denny, in N. Mavine, 

 Shetland, with note on an easy method of its detection. — In the seasons 1910 and 

 1911 this interesting parasite of the rabbit {Lepus cuniculus) has occurred 

 frequently here both on the mainland and on the islands in Yell Sound, 

 -fir. ventricosus is a very torpid creature — almost invariably to be found 

 anchored to the skin of its host. Nevertheless, its small size renders it 

 inconspicuovis when sought for by turning back the fui-. It may, however, be 

 readily obtained by skinning the rabbit and examining the inner surface of the 

 skin for the darker area surrounding the puncture made by the proboscis of 

 the louse. If the finger is placed over the spot and the skin reversed the 

 parasite will be seen at once. 



As regards the parts of the body affected, the flanks, the neighbourhood 

 of the mammae, and generally, one might say, regions where the fur is thinner, 

 seem most liable to attack. — J. Watebston, The Manse, Ollaberry, Shetland :

Note on Prosopis genalis. Thorns. — I was greatly pleased to see noted by 

 Mr. C. H. Mortimer in this Magazine (ante, p. 91), the occurrence of Prosopis 

 genalis, Thoms., in Surrey, and have thought it advisable to add that I had re- 

 corded this species from Berkshire in the " Victoria History " of that county. It 

 would, perhaps, have been better had I done so in this Magazine as well as in 

 that rather inaccessible publication. The specimens in my collection bear the 

 following data : " July 8, 1900, <J and ? near Wokingham ; August 8, 1900, 

 1 V . Wellington College ; August, 1901, 1 ? , Padworth, near Aldermaston ; 

 August 18, 1904, 1 ? , Wellington College. The late Mr. Edward Saunders 

 kindly confirmed the identification and at the same time said they were the 

 first specimens he had seen since those captured near Hastings, in 1879. — A. H. 

 Hamm, 22, Southfield Eoad, Oxford : April I5th, 1912.
