140 MANDIBULATA. — COLEOPTERA. 



Taken in marshy districts near London, frequenting the flowers 

 of Caltha palustris. 



Sp. 11. bolitophagum. Valde convexum, nigrum, antennis pedibusque rufo- 

 piceis, elytris striatis, apice fuscis, inter stitiis striarum punctulatis. (Long, 

 corp. 1 lin.) 



De. bolitophagus. Marsham. — Ce. bolitophagum. Steph. Catal. p. 62. No. 637. 



More convex and smooth than the last : of a very glossy, deep, immaculate black : 

 the elytra very faintly and delicately striated : the interstices finely punctured, 

 dusky, with the apex fuscous : the antennae and legs rufo-piceous. 



The glossiness and convexity of the body, and faintly striated elytra, form the 

 chief difference between this and the foregoing species. 



Not common : found near London ; occasionally in Boleti. 



Sp. 12. immune. Convexum, atrum-nitidum, elytris obsoletissime striatis, an- 

 tennis pedibusque testaceo-ferrugineis. (Long. corp. £— 1 lin.) 

 Sp. immune. Kirby MSS.—Ce. immune. Steph. Catal p. 62. No. 638. 



Convex, shining black; head and thorax immaculate: elytra very obsoletely 

 striated, the striae composed of minute impressions ; the interstices smooth, 

 the apex slightly piceous : antennae and legs rusty-testaceous. 



The very faint and nearly obsolete striae on the elytra, and the nearly immaculate 

 apex of the latter, are the principal characters of discrimination between this 

 species and all the foregoing. It has been called in some cabinets by the 

 name of Sphaeridium laeve. 



Found in Norfolk and Suffolk, and occasionally near London. 



Sp. 13. laevigatum. Valde convexum, nigrum, antennis pedibusque rufo-piceis, 



elytris striatis, interstitiis striarum impunctatis. (Long. corp. 1 — 1^ lin.) 

 Sp. laevigatum. Kirby MSS.—Ce. laevigatum. Steph. Catal. p. 62. No. 629. 



Glossy black, very convex, head and thorax immaculate ; elytra rather faintly 

 striated, the interstices impunctate, black, with the apex rather obscurely 

 pale or pitchy : antennae and legs pitchy-red : palpi and club of the antennae 

 dusky. 



The smooth interstices between the striae on the elytra, and the superior bulk of 

 the insect, distinguish it from Ce. bolitophagum, which it most resembles. 



Also found in Norfolk and Suffolk, and sometimes near London ; 

 at Hertford and Ripley. 



Sp. 14. apicale. Ovatum, atrum-nitidum, concinne punctatum, elytris tenue punc- 

 tato-striatis, atro-piceis, apice castaneo. (Long. corp. f — 1 lin.) 



Ce. apicale. Steph. Catal. p. 62. No. 640. 



Ovate: head and thorax glossy pitchy-black, immaculate, the entire surface 

 beautifully and thickly punctured ; elytra deep piceous, with the apex casta-
