SPHiERIDIIDiE. — CERCYON. 147 



Subconvex, obscure dull aeneous, the elytra very obsoletely striated: the inter- 

 stices obsoletely punctulated, the apex concolorus : antenna and legs dull 

 black. 



The obscure brassy hue of the upper surface of this species, and the obsoleteness 

 of the striae on the elytra, with the black legs and antennae, well distinguish it 

 from the rest of the genus. 



I have but one example of this species, which I procured from 

 the Marshamian cabinet by the above name; not as the De. ni- 

 grinus of Entomologica Britannica, which was also in the col- 

 lection. 



Sp. 36. immaculatum. Ovatum,convexum,piceum, nitidum, elytris piceo-nigris 

 immaculatis, obsoletissim'i striatis, pedibus piceis. (Long. corp. f lin.) 



Sp. immaculatum. Kirby MSS. — Ce. immaculatum. Steph. Catal p. 64. 

 No. 662. 



Ovate, convex ; glossy pitchy-black ; head black : thorax piceous, thickly punc- 

 tulated : elytra of an immaculate pitchy-black, very obsoletely striated, the 

 interstices scarcely punctulated ; legs piceous : antenna and palpi rufescent. 



This minute species is distinguished by having the apex of the elytra concolorous, 

 and the elytra scarcely striated or punctured. 



Found near London and in Suffolk. 



Sp. 37. stercorator. Oblongo-ovatum, atrum, nitidum, elytris obsolete striatis, 



interstitiis creberrime punctulatis, apice piceis. (Long. corp. -^ — ^ lin.) 

 Sp. stercorator. Kirby MSS. — Ce. stercorator. Steph. Catal. p. 64. JVo. 663 . 



Minute : oblong-ovate ; deep glossy-black ; head and thorax immaculate : elytra 

 very obsoletely striated, the interstices thickly punctulated, the apex piceous : 

 femora pitchy-black : tibiae and tarsi rufescent ; antennae with the club, and 

 the palpi, dusky. 



Less than C. minutum, which it greatly resembles, but differs in having the 

 apex of the elytra pitchy, and slightly in form: — from Ce. merdarium it 

 differs in having the tibiae and tarsi rufescent. 



Found near London and in Suffolk. 



Sp. 38. merdarium. Oblongo-ovatum, aterrimum, subnitidum, elytris obsolete 



striatis, apice rufescente. (Long. corp. \ lin.) 

 Sp. merdarium. Sturm ?—Ce. merdarium. Steph. Catal. p. 64. JVo. 664. 



Oblong-ovate, rather shining : head and thorax deep black, immaculate ; elytra 

 rather faintly striated, the interstices obscurely punctured ; deep black, the 

 apex pale rufescent ; legs, antennae, and palpi entirely of a deep black. 



The nearly jet-black hue of this minute species, which has merely the apex of 

 the elytra coloured, sufficiently points out its distinction from its congeners : 

 it is probably the Sph. merdarium of Sturm, but his figure is without the 



* setae on thejtibiae, which, if correct, would seem to indicate a generic dif- 

 ference.
