NEW BRITISH SPECIES, ETC., IN 1861-62. 87 



authority of a single specimen in his own collection ; it has 

 since been taken by him (in cow-dung in the field opposite 

 the inn at Birchwood), also by myself and Dr. Power, and 

 is most probably mixed with O. laqueatus, Marsh., in col- 

 lections. 



It may be distinguished from the latter sjoecies by its head, 

 which has only one central longitudinal groove on the back, 

 and is also more punctured in front, with the space of the 

 clypeus less concave, and the clypeus is not so acute at the 

 angles ; the bulk of the eye is also much larger than in 

 laqueatus; and in the male the sixth segment beneath is 

 bisinuate, and the seventh tricuspid, whilst in laqueatus the 

 sixth segment has two tubercles, and the seventh is bisinuate 

 and produced into a mucro. 



57. OxYTELus MARiTiMUS, Thomson ; G. R. Crotch, Zool. 



8083 (1862). 



Mr. Crotch records this species as taken in tolerable abun- 

 dance under sea-weed on the Somersetshire coast, and says 

 it resembles O. inusi-us, Grav., but may be known by its 

 testaceous antennae and more scattered punctuation. 



This is most probably the Oxyfelus allied to inastus taken 

 on the coast, and distinguished long ago by Mr. T. J. Bold, 

 who has sent it to myself and others as distinct ; but I am 

 unable to speak decidedly on the point, not having seen the 

 original description o^ maritimus, which is, I presume, in the 

 recently published part of Thomson's work. 



58. Ancyrophorus longipennis, Fairm. et Lab., Faun. 



Fr. iii. p. 614 (TrugophlcBus) ; Wat. Cat. p. 108 

 (1861). 

 Distinguished from A. omalinus, Erichs.,by its larger size, 

 longer antennae and longer and more robust elvtra.
