horstj which seems to be a much smaller msect, and to differ in other 

 respects. 

 The two species will probably hereafter be formed into a genus. 



" Taken in putrid wood at Holme-juxta-mare, in Norfolk, in 

 August, ISOjr—Kirby MSS. 



Genus CCCCXCVIII.— Cypha, Kirhy MSS. 



Antennce 11-jointedj basal joint very stout, second also robust, both consider- 

 ably stouter than the remainder, five following slender, the three terminal 

 ones incrassated, the last being ovate-acute, or elongate-lanceolate. Falpi 

 subacuminated, with the terminal joint very minute : head sessile, transverse, 

 inflexed: thorax convex, a little narrowed in front: body ovate, convex; 

 coleoptra also convex, rounded on the sides, broader and longer than the 

 thorax: abdomen very short, acute, nearly entirely retracted beneath the 

 elytra: legs slender; tibice slightly setose; far^z pilose. 



The minute insects comprised in this genus may be readily 

 known from the other Brachelytra by the great bulk and convexity 

 of the anterior portion of the body, compared with their minute 

 conic abdomen ; the tenuity of its antennae and the three distinctly 

 thickened joints at their apex form also a good distinguishing 

 external character. The species usually reside in fungi or rotten 

 wood. This genus is probably synonymous with the genus Hypo- 

 cyptus of Schiippell.

5/acA:, slightly glossy, and glabrous: head transverse: thorax ample, rather 

 glossy, and obscurely punctured : elytra piceous or castaneous : abdomen 

 black : legs and antennae pale testaceous, the latter very slender. 



Found not very rarely within the metropolitan district ; also in 

 Devonshire and Norfolk. " Swansea."" — L. W. Dillwyn, Esq.

 Cy. rufipes, Kirhy MSS.—Steph. Catal. 272. No. 2846. 



Black, smooth, slightly shining: head narrow, sessile: thorax with the lateral 

 margins faintly piceous : elytra scarcely twice as long as the thorax, very 

 slightly pubescent, obliquely truncate : abdomen acute, margined, finely 

 pubescent, the apex sometimes slightly recurved : legs ferruginous : antennae 

 also ferruginous, with the terminal joint elongate-lanceolate.
