NOTES ON NEW BRITISH COLEOPTERA SINCE 1871; 



WITH NOTICES OP DOUBTFUL SPECIES, AND OF OTHERS THAT 



REQUIRE TO BE OMITTED FROM THE BRITISH LIST. 



BY THE EEV. W. W. FOWLER, M.A., F.L.S. 



{continued from p. 126.) 



[Owing to a mistake, the words "flown across the channel " were applied, on 

 p. 122, to C. auratus, instead of to Calosoma syco-phanta, a few lines down ; I am 

 sorry that so obvious an inversion escaped notice.] 



HYDEOPHILID^. 



Philhtdrus sutuealis, Sharp. 



This species is allied to P. marginellus, Thorns., but is larger, with yellow palpi ; 

 the clypeus has a yellow spot on each side in front of the eye, and the elytra are 

 dull testaceous, with the suture black. It appears to be very common both in Eng- 

 land and Scotland, and collectors will probably find that most of their P. marginellus 

 belong to this species, if they examine them ; in P. marginellus. Thorns., the elytra 

 are of a browner colour, the thorax is darker, the head black and unspotted, and the 

 last joint of the palpi black (Ent. Mo. Mag., ix, 153 ; Ent. Ann., 1873, 22). There 

 is very great confusion with regard to the synonymy of P. marginellus, 



Helocliares punctatus, Sharp. 



This species can hardly be separated from S. lividus, Porst. 



A.nac(Bna variahilis, Sharp. 



This appears to be considered on the continent a variety of A. limhata ; it is, 

 however, a very good species, and may be distinguished at once by its long oval 

 shape, which is entirely different from that of A. limhata. I have taken it in num- 

 bers in the New Forest, unaccompanied by the latter species. 



Helophoeus tubeeculattjs, Gyll. 



This insect may be easily distinguished by its deep black colour, and by the 

 polished tubercular elevations on the second, fourth, and sixth interstices of its un- 

 even elytra. Taken in the Manchester district by Mr. Chappell, and in Yorkshire 

 by Mr. T. Wilkinson (Ent. Mo. Mag., xi, 135, 235). 



Helophoeus ^qualis, Thorns. 



Allied to H. aquaticus, but smaller, with the sides of the thorax less rounded, 

 and its surface less closely granulose ; there are also other differences, but it would 

 seem very difilcult to separate the species from S. aquaticus, of which it appears to 

 be a small variety. It appears to be common, and to occur with this latter species. 

 I have taken it at Repton, and near Lincoln (Ent. Mo. Mag., xi, 39). 



Helophoeus beevicollis, Thorns. 



Said to be allied to H. granularts, but distinguished by the sulci of the thorax, 

 and by the elytra being narrower and more pointed at the apex, and having the 

 sides more parallel ; the punctures in the striae on the elytra are finer and closer, 

 and the interstices between the strise are much narrower and more elevated. Taken 

 at Killarney by Rev. T. Blackburn (Ent. Mo. Mag., xi, 39). I have a Scotch speci- 

 men named as H. brevicollis for me by M. Brisout, which appears to be very close 

 to ceneipennis.
