16G STAPHYLiNiDJ!. [Lejjtusa. 



This species has much the general appearance of an Ocyusa, but 

 apart from other things its habitat is quite different, 



SIPAZiZA, Key. 



This sub-genus contains a large number of species that have until 

 recently been included under Leptm^a ; as above stated, Pachygluta, 

 which only appears to diifer slightly from 8ip<iliaj is here included 

 uaider it as a sub-genus; Sipalia is distinguished from Leptusa by having 

 the intermediate coxae contiguous, by the absence of wings, and also 

 by having tlie hind body more or less widened behind ; the elytra 

 also, as a rule, are shorter, and the mesosternal plate is prolonged in a 

 sharper point. 



I. Eyes small ; mesosternal plate prolonged in a very sharp pohit 

 (sub-gen. Pachygluta, Thorns.); head and elytra black, thora.K 



bright reddish testaceous S. KTIFICOILIS, Hr. 



II. Eyes very small ; mesosternal plate produced in a less sharp 

 point {Slpalia i. sp.); colour chiefly testaceous, with the head 



and hind body, except base and apex, darker S. tesTaCEA, Bris. 



S. ruficollis, Er. {Pachygluta ruficollU, Thoms.). Elongate and 

 narrow, Avith the head, elytra, and more or less of hind body before 

 apex black, thorax clear red, and base and apex of hind body more or 

 less broadly reddish or testaceous ; head almost as broad as thorax, an- 

 tennae moderately stout, pitchy, with the two or three first joints and 

 the last joint testaceous, penultimate joints strongly transverse ; thorax 

 nearly as broad as elytra, finely punctured ; elytra at suture shorter 

 than, or about as long as, thorax, rather strongly and rugosely punctured; 

 hind body widened behind, finely punctured in front, almost smooth 

 behind; legs reddish testaceous. L. 2 mm. 



Male with a raised prominence on each elytron near suture ; sixth 

 segment of hind body furnished with a small tubercle near apex, seventh 

 segment emarginate. 



Under bark, and in dry moss on old trees ; not uncommon ; London district, 

 general ; Glanvilles VVootton, Dorset ; New Forest ; Malvern ; Midland districts, 

 Repton, &c., common ; Lincoln ; Northumberland district ; Scotland, local, Lowlands 

 and Highlands, Tweed, Solway, Forth, and Tay districts. 



This insect is the type species of Thomson's genus Pachygluta, the 

 characters of which are that the hind body is widened at apex, and the 

 elytra are not longer than thorax (Skand. Col. i. 32). 



S. testacea, Bris. (Slpalia testacea, Muls. et Eey). Testaceous, 

 with the head sometimes darker, and the hind body more or less broadly 

 pitchy except at base and apex ; head large, as broad as thorax, nar- 

 rowed in front of eyes, sparingly punctured, antenuce as long as head 

 and thorax together, brownish with base testaceous, slightly thickened,
