Eare ; in chinks and crevices of beech and other trees near the 

 runs of Formica fuliginosa : Birch Wood, Tilgate, Coombe Wood, 

 Mickleham, Horsell, Maidstone, &c. 



Omosita, Erichson. 



1. Length, 1? lines; thorax ferruginous, elytra strongly margined, 



O. depressa, Linn. — Entirely of a rust-red colour, except the head, scutellum, 

 centre of thorax, and a few scattered spots on elytra, which are darker ; thorax with 

 two impressions on disc behind middle, and a strong longitudinal furrow on each 

 side ; posterior margin very distinctly bisinuate ; elytra Tery finely, almost invisibly, 

 punctured, with strong margins. 



A local species, common in the north of England and in Scotland ; 

 it is usually found under old bones ; Aviemore, Braemar, Dumfries, 

 North Derbyshire, Llangollen (under stones), Shiere, &c. ; Stephens' 

 gives Bottisham, Netley, and Glanvilles Wootton, as localities. 



2. Length, IJ lines ; thorax dark, with margins somewhat lighter ; elytra very 



slightly margined. 

 O. colon, Linn. — This and the next species are at once distinguished from the! 

 preceding by their much smaller size, different colouring, less close punctuation 

 more oblong form, and much narrower margins of elytra ; in fact, O. depressa mighl 

 for many reasons be made a separate genus. 0. colon may be separated from 

 discoidea by its colour, which is dark, with the margins of the thorax somewhal 

 lighter ; the elytra have each a rather small spot behind middle, reaching to suture 

 and a few other light spots towards base ; the thorax is strongly rounded and con 

 tracted in front, so that the anterior margin is considerably narrower than th 

 posterior, and the base shows very slight traces of sinuation. Length, 1 — 15 lin 



Very common under old bones, and generally distributed. 



0. discoidea, Fabr. — Distinguished from the preceeding by having the thora^ 

 not much contracted in front, so that the anterior margin is nearly as broad as tt 

 posterior, and by the elytra having a common light yellowisli spot reaching from bafi fj]^ 

 to beyond middle, and from suture nearly to side margin : the posterior margin 

 the thorax shows hardly a trace of sinuation. Length, 1—1^ lin. 



Very common under old bones, and generally distributed.

Pkia, Kirby. 

 This genus at first sight closely resembles Meligethes, but is di 

 tinguished by the oblong club of its antennae, by the thorax having 

 lateral stria close to margin, and by the simple front tibise. 



P. dulcanara, 111. — Eather smaller than Meligethes ceneus, of a dark olii 

 testaceous colour, with suture of elytra and under-side darker; punctuation 

 thorax fine, of elytra almost invisible ; legs yellow ; anterior tibi® simple ; undeii 

 high power slight traces of teeth are visible, and the posterior tibiae are seen to 

 clothed with very short white hairs on their margins ; the antennge are rather lonj 

 in the males than in the females, and the eighth joint in the former sex is enlarg 

 laterally, so that the club appears to be four-jointed in the males, and three-joini
