144 MANDIBULATA. — COLEOPTERA. 



faintly punctured; the apex pitchy-red: legs pitchy-black, with the tibiae 



and tarsi paler. 



Found occasionally in Norfolk and Suffolk, and near London. 



Sp. 26. infuscatum. Convexum, atrum, opacum, thorace gibhose pulvinato, elytris 

 piceo-nigris, apice paulo dilutiori. (Long. corp. § lin.) 



Ce. infuscatum. Steph. Catal p. 63. No. 652. 



Similar in form to the three last, but much smaller: of a deep obscure black ; 

 head and thorax immaculate, thickly punctulated, the thorax very gibbous : 

 elytra very obsoletely striated, the interstices scarcely punctured and rather 

 flat; deep opaque pitchy-black, with the apex rather paler : legs entirely of a 

 castaneous-red. 



This and the three last are of a more convex form than the rest of the genus : 

 they may be readily known from each other by the characters above given. 



Not common : found near London. 



Sp. 27. impressum. Ovatum, atrum nitidum, capite thorace maculdque triangulari 

 ad scutellum nigris, elytris pedibusque rufo castaneis. (Long. corp. 1^ — 

 If. lin.) 



Sp. impressum. Sturm. — Ce. impressum. Steph. Catal. p. 63. No. 653. 



Larger than the following: ovate, glossy: head and thorax deep black, im- 

 maculate; elytra deep rufo-castaneous, with a large triangular black patch 

 at the scutellum : the disc punctate-striated, the striae rather deep, the in- 

 terstices thickly punctate; legs also bright rufo-castaneous: antennae pale 

 testaceous ; palpi dusky. 



Considerably larger than the following species, and without the lateral black 

 streak at the base of the elytra, as in that and Ce. conspurcatum. 



Also somewhat rare : taken near London, and in Hampshire. 



Sp. 28. melanocephalum. Oblongo ovatum, nigrum, elytris rufo-testaceis, maculd 



baseos communi triangulari alterdque laterali nigris. (Long. corp. § — 1 lin.) 



De. melanocephalus. Linne. — Ce. melanocephalus. Steph. Catal. p. 63. No. 654. 



Oblong-ovate, shining: head and thorax deep immaculate black, punctured: 

 elytra rufo-testaceous, with a large triangular common black spot at the base, 

 and another smaller one at the outer anterior angle ; the surface finely and 

 thickly punctured, and rather faintly punctate-striated : legs rufo-testaceous : 

 antennae and palpi dusky-black. 



Var. /?. Steph. Catal. 1. c. — With the femora deep black. 



The smaller size, more elongate form, dark antenna? and palpi, and black patch 

 at the lateral angle of the elytra, sufficiently distinguish this from the fore^- 

 going ; and the former characters discriminate it from the following. 



Found copiously from April to June in meadows and pastures* 

 throughout the metropolitan district.
