NEW BRITISH SPECIES, ETC., IN 1861-52. 69 



know their history ; this notice, however, may call attention 

 to the matter, and possibly other examples may be found. 



9. Stenolophus derelictus, Daws.; Wat. Cat.; Solomon, 



Zool. 7408 (1861). 

 The opinion of Dr. Schaum (recorded in Ent. Annual, 

 1860, p. 25) that this is only a dark var. of dorsalu, Fab., 

 is certainly correct, so far as can be judged from specimens 

 in metropolitan collections; but Mr. Dawson told me long 

 ago that the example in his possession, upon which he had 

 founded the species, was unlike any others he had seen. 



10. Bembidium nigricorne, GylL ; Wat. Cat. p. 107 



(1861). 

 In the Proc. Ent. Soc. 3rd Mar. 1862, Zool. 7981 (1862), 

 will be found a letter from Mr. Wailes of Newcastle, the 

 original captor, establishing the locality of Mr. Waterhouse's 

 specimens, amongst others. 



11. Laccophilus variegatus, Germar, Faun. Ins. Eur. 



iii. 6 {Dytiscus); Aube, Sp. 439; Wat. Cat. p. 107 



(1861). 



At once known from its congeners by its narrow shape, 



and the bright and well-defined markings on its thorax and 



elytra, the latter being dark and glossy. Fii^t taken by the 



Rev. H. Clark, plentifully, near Arundel I believe, in 1860. 



12. Hydrgporus quinquelineatus, Zetterst. Faun. Ins. 



Lapp. i. 335 {Hfjphijdrus)'^ Aube, Icon. 367, pi. 42, 

 fig. 2; Rev. H. Clark, Proc. Ent. Soc. 1 Sept. 1862, 

 Zool. 8219 (1862), Journ. Ent. 1, 469. 



Hydroporus 1* sp. ? Wat. Cat. p. 107 (1861).. 



Closely allied to H. reticulatus, Fab., and distinguished 

 from it by the longitudinal markings of the elytra, which are
