NEW BRITISH SPECIES, ETC., IN 1869. 97 



V. Harold. From an examination of Mr. Waterhouse's 

 notes, I find it is H. riparia, apparently immature, and 

 accidentally omitted from the synonymy of his Catalogue. 



140. Philhydrus punctatus, Sharp, Ent. Mo. Mag., v, 



241 {Helochares) , described. 



Dr. Sharp has detected, among the common P. lividuSy 

 a species which he describes under the above name, stating 

 that it is generally distributed in England (Whittlesea Mere, 

 Cambridge, London, New Forest), but apparently not so 

 common as lividus. From his diagnosis it is rather smaller 

 than that insect, with the -apex of the palpi not so narrowly 

 darkened, brownish-testaceous in colour, and rather strongly 

 punctured all over the upper surface, — the punctures being 

 more evident than in lividus, in which, moreover, the apex 

 of the elytra is delicately and more sparingly punctured. 



I find that half of my so-called lividus must be referred to 

 Dr. Sharp's insect, and fancy that in them the eyes and palpi 

 are more bulky than in true lividus. Dr. Power informs 

 me that P. lividus is abundant at Sheerness and Gravesend; 

 whereas P. punctatus occurs, in his experience, at Wimble- 

 don and other inland localities. 



141. Cyphon fuscicornis, Thorns.; Kies., Berl. Ent. Zeit., 



1867, 407; Dallas, Rec. Zool. Lit., iv, 1867, pt. 2, 



261; E. C. Rye, I.e., v, 198. 

 According to Kiesenwetter, 1. c, this insect is only the 

 female of C. coarctatus, Payk. Stein adopts this view. If 

 this be right, we may expect to see certain other species, 

 distinguished by somewhat similar characters, eventually 

 suppressed.
