NEW BRITISH SPECIES, ETC., IN 1872. 15 



ciles the size (the same as for ovalis) and black autenuce of 

 Stephens' insect with that of Erichson. 



Eusphalerum is fused with Authoblum. 



Homalium nigrum^ Grav., is united as a species with 

 florale^ Er. (for which the name ritfipes, Fourcroy, is 

 adopted), the intermediate gradations being stated to occur. 



H. punctipenne and abietinum, Thomson, are rejected as 

 " spUts" of ptisillu?n, Grav. 



If. nigriceps, Kies., apart from its evident colour differ- 

 ences, is distinguished from ccesum by its smaller size, and 

 being more narrowed in front, more convex, with the head 

 more convex in the middle and finely (not rugosely) punc- 

 tured, the thorax more narrowed, convex, and cordiform, 

 much less closely punctured, with shorter and deeper fovere, 

 narrower and shorter elytra and smooth abdomen. 



H. excavatum, Stephens, is adopted for fossulatum, Er. : 

 but the excavatiun of Stephens' collection is oxyacanthce. 



H. ocellatum, Wollaston, is now admitted to be distinct 

 from Allardi. 



Philorhinum sordidiim, Stephens, is adopted for sub- 

 pztbcsce?is, Steph., hiunile, Er. : but Stephens' insect is 

 Homalium iopterum. 



Tlie Arpedium brachypterum of our Catalogues is re- 

 ferred to troglodytes, Kies., Ktz.; Gravenhorst's brachypte- 

 rum being separated, and yet indicated as most probably 

 only a winged form of the same species. 



Lesteva miiscorum, Duv., is considered to be the true 

 punctata, Er. ; and L. punctata, Ktz. (the smaller species) 

 is renamed Heeri. 



Geodromicus nigrifa, MiilL, and globulicollis, Zett., are 

 united, with other insects hitherto deemed specifically dis- 

 tinct, under the nnme plagiatus, Er., as mere races. 



Actocharis Readingii, Sharp, under the naiiie marina,
