October, 1884.] 0-7 



A very local species, but somewhat plentiful where it occurs ; I 

 lave found it in numbers in Sherw^ood Forest with Mr. Matthews, by 

 baking faggots over a sheet, also a smaller variety by beating faggots 

 'f a species of Tilia (called "bass " by the country people) in Lang- 

 rorth Wood, near Lincoln ; Stretford, flying over old wood -yard, Mr. 

 leston ; Aviemore ; Daren th, faggot stacks, Mr. Champion ; also taken 

 ear Scarborough. It will be noticed that the habitat of this species 

 \ rather peculiar. 



E. immunda, Er. — This species is very little known, and others are perpetually 

 lade to do duty for it in collections ; it is perhaps best distinguished superficially 



Y the colour ; the apex of the elytra and the sides, for the greater part of tiieir 

 ngth, are suffused with dark colour, and the space of the elytra enclosed within is 

 staceous; this, however, is not always the case; the margins of the thorax are 

 irrow, of the elytra very pronounced ; the thorax is contracted towards base with 

 sinuation, and is as broad as the elytra without the margins, which make it appear 



iltrrower. From E. deleta, which it approaclies in some points, it may be distin- 

 lished by its col ur and the darker club of its antennae ; from E. obsoleta, with 

 liieh it is most often confounded, it may be separated by its broader form, and by 

 iving the last joint of the antennae about as broad as the penultimate, whereas, in 



, .. obsoleta it is distinctly narrower ; the thorax also is slightly more contracted at 



[f«e than in the latter species. Male with intermediate tibiie sinuate. 



Length, 1^ lin. 

 A very rare species. Mr. Champion has taken it at sap of birch 

 i Aviemore and Invercannich, Scotland, and Messrs. Wilkinson and 



Iiiwson at Scarborough. 

 : E. variegata, Herbst. — A very distinct species of a dark red-rust colour, with 

 tinsverse evenly rounded thorax, which is strongly contracted at base, the base 

 ling much narrower than the base of elytra ; tlie sides show no trace of sinuation ; 

 «;h elytron has a strong blackish spot in the centre, and a smaller and more obscure 

 ca at apex; punctuation distinct, rather strong; male with intermediate tibige 

 s^ple- Length, 1» lin. 



A very rare species ; Aviemore, Scarborough, Surrey ; found at 

 sp or under bark. 



E. obsoleta, Fabr. — One of tlie most difficult species of the genus to determine ; 

 vnable both in size, colour, and to a certain extent in structure of thorax, and i\\ 

 c [Sequence often confounded with other species ; the elytra are, as a rule, obscurely 

 Brked with dark patches, but occasionally the whole insect is of a reddish colour, 

 al may in that case be confounded with species belonging to the first group, as E. 

 Ji'ea-, from this species small unicolorous examples of E. ohsoleta may be distin- 

 gshed by the plain emargination of the anterior margin of the thorax, and by the 

 dk club of the antennae ; from E. pusilla, which it often closely resembles, E. 

 ■ ooleta may be distinguished by the emargination being much less, by its truncate 

 etra, more rounded sides, and narrower margins of thorax, and by the dark club 

 Olts antennae; from other neighbouring specie?, such as E. parvula, it maybe 

 8(arated by the sinuate intermediate tibiae of the male. Length, f— U lin.
