answer in all respects to this species ; three males taken at Wliittlesford 

 (Cambs.), New Forest, (Hants), and Porthcawl (Glamorgan) woiUd appear to 

 represent G. fascipes, Becker, having only one dark spot on the plem-cfi (a streak 

 on the meso-pleiu-a) and the hind tibia3 with a dark ring- near the base, but 

 everything points to these characters being only sexiial. 



Selachops flavocinda, Wahlbg. — I have not seen a British specimen of this 

 genns which is now placed among the Agromysidas.

A NEW BRITISH HALIPLUS. 

 BY FRANK BALFOUR BROVPNE, F.Z.S. 



Since the appearance of the paper by Edwards, entitled, " A 

 Revision of the British Species of Hallphts, Latreille" (Ent. Mo. 

 Mag., xlvii, pp. 1 — 10, Jan., 1911), I have been working out my 

 material, and find that I have a species of the " nt/?coZZis-group " 

 which is not included in that paper. 



The male is at once distinguished by the form of the sedeagus, which 

 differs from that of all the other species of the group, and it has the 

 claws of the anterior tarsi practically equal in length, which separates 

 it from riificollisjfulvicollis, wehncJcei, and immacuJatus. One easily seen 

 character also distinguishes it from all the seven species of the group, and 

 that is the shape of the basal segment of the median tarsi. This 

 segment has a very noticeable curve when viewed laterally, and gives 

 the impression of a portion having been neatly taken out of the inner 

 margin. 



I believe that the female has the interstrial spaces of the elytra 

 finely punctured throughout, as described by Edwards, for the female 

 of H. ruficoUis, De G. 



The species occurs in England, Scotland, and Ireland, and so far 

 as my experience goes, it is found in lakes and canals, and large drains 

 of clear water. 



I am now preparing a somewhat detailed paper on the Halipli of 

 the i-nficoUis-grouTp, as there are several points upon which I do not 

 agree with Mr. Edwards, and in that paper I intend giving a full de- 

 scription of this additional species, if it should prove to be new to 

 science, a point I have not yet made certain of. In the event of its 

 being new I propose to name it Haliplus nomax.
