the specimens with paler legs generally having the prevalent colour pitchy- 

 black or somewhat castaneous, and are probably immature. 



Common throughout the metropolitan district. 



Sp. 43. obscurum. Ovatum, obscuro-piceum, margine thoracis elytrorumque 



apicihus rufis, pedihus piceis. (Long. corp. y 2 lin.) 

 De. obscurus. Mar sham. — Ce. obscurum. Steph. Catal. p. 64. A T o. 669. 



Ovate: dull piceous, glossy: head pitchy: thorax piceous, the margin ru- 

 fous; elytra rather flat, very obsoletely striated, piceous, with the apex 

 rufous : legs piceous : palpi dusky : antennae pale rufous, with the club of a 

 deeper hue. 



The rufescent margin of the thorax, bright rufous apex to the elytra, which are 

 most obscurely striated, and dull-pitchy colour, distinguish this species. Its 

 habit is very dissimilar to that of the rest of the genus. 



From the Marshamian collection. 



Sp. 44. contaminatum. Ovatum, convexum, piceo-nigrum, elytris obsoletissimi 

 striatis castanets, apice pallidiore. (Long. corp. ^ l m 



Sp. contaminatum. Kirhy MSS. — Ce. contaminatum. Steph. Catal. p. 64. 

 No. 670. 



Ovate, very convex, slightly attenuated behind : head pitchy-black, immaculate : 

 thorax rather glossy, pitchy-black, with the lateral margins obscurely rufous 

 anteriorly: elytra very obsoletely striated, the interstices impunctate, deep 

 pitchy chestnut, with the apex slightly paler : legs, antennae, and palpi rufo- 

 castaneous. 



The ovate, slightly attenuated posterior extremity of this minute convex species, 

 with its deep pitchy colour, and castaneous obscurely striated elytra, dis- 

 criminate this insect from its congeners. 



Taken near London, and in Suffolk : also I believe in Norfolk. 



Sp. 45. concinnum. Ovatum, atrum, nitidum, thoracis margine elytrisque 



piceo-testaceis, pedihus rufis. (Long. corp. | — § lin.) 

 De. concinnus. Marsham. — Ce. concinnum. Steph. Catal. p. 64. No. 671. 



Ovate, shining : head black, immaculate : thorax black, with its anterior and 

 lateral margins testaceous: elytra deep pitchy- testaceous, rather faintly punc- 

 tate-striated; the interstices impunctate : legs rufous: antennae and palpi 

 the same. 



Closely allied to the last, but rather larger ; the black head, coloured margins 

 of the thorax and pitchy-testaceous elytra, however, sufficiently distinguish 

 it therefrom. 



Occasionally found near London ; in Norfolk and Suffolk. 



Sp. 46. ferrugineum. Ovatum, nitidum, saturate rufo-ferrugineum, immacu- 



latuni. (Long. corp. | — 1 lin )
