Sp. 29. conspurcatum. Oblongo-ovatum, nitidum nigrum, elytris pallida rufo- 

 testaceis, elytris macula, baseos communi triangulari humerisque nigris, an~ 

 tennis pedibusque pallide testaceis. (Long. corp. g — § lin.) 



Sp. conspurcatum. Sturm. — Ce. conspurcatum. Steph. Catal. p. 63. No. 655. 



Oblong-ovate,, shining: head and thorax black, immaculate: elytra pale rufo- 

 testaceous, finely punctured, and rather delicately punctate-striated, the base 

 with a large common triangular black spot, and the lateral margin with an 

 elongate black streak : legs pale rufo-castaneous ; antennae the same ; palpi 

 dusky, sometimes pale-testaceous. 



This minute species varies considerably in size : it differs from the last in its 

 smaller size,, paler antennae and legs, and the dissimilarly formed streak at 

 the base of the elytra. 



Apparently very abundant near Lyndhurst in the New Forest, 

 but less so near London. 



Sp. 30. atomarium. Ovatum, nigrum, obscurum, punctatissimum, elytris pro- 

 fundi crenato-striatis, apice pedibusque ferrugineis. (Long. corp. | — § lin.) 

 Sp. atomarium. Fabricius. — Ce. atomarium. Steph. Catal. p. 63. No. 656. 



Small: ovate, black, obscure, thickly punctured: palpi and antennae piceous: 

 head and thorax immaculate : elytra broad, dilated at the sides, slightly de- 

 pressed, striated, the striae very deeply crenate-punctate, the interstices ele- 

 vated, thickly punctulated, black, obscure, the apex more or less rufescent : 

 legs rusty-red ; the femora sometimes piceous. 



The deeply crenate striae on the elytra of this species discriminate it from all 

 the other species. It varies greatly in size. 



Extremely common in the neighbourhood of London. 



Sp. 31. sordidum. Ovatum, obscuro-piceum, capite nigro, elytris rufo-piceis, 



punctato-striatis, pedibus piceis. (Long. corp. 1 lin.) 

 De. sordidus. Marsham. — Ce. sordidum. Steph. Catal. p. 63. No. 657. 



Ovate : head black : thorax pitchy-black, punctulated : elytra pitchy-red, punc- 

 tate-striated, the interstices finely punctured : breast black, punctulated ; ab- 

 domen beneath rufo-ferrugineous, or piceous : legs piceous : antennae black, 

 rufous at the base. 



Allied to the last in form, but the striae less impressed, the colour different, &c. 



The Marshamian specimens alone are the only ones that I have 

 hitherto examined ; I am ignorant of their locality. 



Sp. 32. convexium. Rotundo-ovatum, atrum, obscurum, antennis pedibusque 

 piceo-castaneis. (Long. corp. \ — | lin.) 



Sp. convexium. Kirby MSS.—Ce. convexium. Steph. Catal. p. 64. No. 658. 



Rounded-ovate, deep obscure black: head and thorax thickly punctured, im- 

 maculate: elytra opaque black, the apex slightly margined with piceous; 

 Mandibulata. Vol. II. 1st February, 1829. l
