small E. nana (described by Mr. Champion in the Ent. Mo. Mag., vol. xxxii, p. 4) 

 is hardly likely to be mistaken for either of them. There is not another species of 

 this group at all likely to occur in Britain. I have had small specimens of E. xstiva 

 doing duty for E.jlorea in my collection, and have seen it in others, as the former 

 sometimes has the anterior margin of the thorax very slightly emarginate, but its 

 greater convexity will at once distinguish it. 



E. parvitla is easily recognised by its dark colour and lighter margins, the very 

 broad sides of the elytra, and the fuscous club of the antennae. 



E. deleta is distinctly broader and less parallel-sided than the last. It is often 

 unicolorous testaceous, or the suture and apex of the elytra are broadly fuscous. 

 Ganglbauer compares it with E. immunda, from which, however, it may be easily 

 recognised by the broader margins of the elytra, finer and more diffuse punctuation, 

 and more emarginate anterior margin of thorax. 



E. neglecta is, as Fowler points out, a very distinct species, although the thorax 

 is hardly broadest at the base as he describes, the sides being slightly and evenly 

 contracted just before the base. The shape of the thorax, strong punctuation, and 

 truncate apex of elytra will at once distinguish it. 



E. variegata, which is distinguished by its very short but conspicuous shining 

 pubescence, is a broad species with the thorax strongly narrowed in front, and the 

 elytra rounded at the sides ; in general shape it most closely resembles E. deleta. 

 E. pusilla has very short somewhat shining pubescence, but the hairs are much less 

 conspicuous, and this species is almost parallel-sided, with a very differently-shaped 

 thorax. 



There should be no difficulty in identifying the very variable E. obsoleta, if the 

 table is carefully followed, and also the description given by Fowler. 



E. immunda is rather more distinct than Fowler's description would imply. 

 Besides the characters given in the table, it differs from E. obsoleta in being less 

 parallel-sided, and the sides of the thorax are more rounded and not so abruptly 

 narrowed at the base. 



E. longula and E. florea. Wtien it is realized that in these two species the 

 anterior margin of the thorax is much less emarginate than in any of the others 

 (except, perhaps, small E. sestiva), and, indeed, is practically straight, no difficulty 

 will be found in separating them, and the characters given in the table are sufficient 

 to identify them individually. In E. longula there is often a dark spot at the apex 

 of each elytron. 



E. thoracica has very parallel-sided elytra, and is easily distinguished from 

 all the other British species by its extremely fine punctuation.* 



E. pusilla is another of the narrow parallel- sided species. Besides the differ- 

 ence in the shape of the thorax, it may be distinguished from E. obsoleta and 

 E. immunda by the concolorous club of the antennae, and from E. parvula by the 

 much narrower border of the elytra. 



There are three species described by G-anglbauer as occurring not rarely in 

 North and Middle Europe, which are perhaps worth describing briefly, in case they 

 should occur here at some future date :— 



„ on * T hisis the species recorded by me as E. oblonga. Herbst (But. Mo. Mag , vol. xliii, pp. 184, 

 234). from Chobham, where the var. sutumlis, Reitt., also occurs. Its identity with E. thoracica, 

 Tourn., was suspected at the time.— G. C. C.
