SPHiERIDIIDiE. — CERCYON. 151 



Sp. 50. nigriceps. Ovatum, atrum, nitidum, thoracis lateribus, antennis, elytris, 



pedibusque rufo-j'errugineis. (Long. corp. f lin.) 

 De. nigriceps. Marsham.—Ce. nigriceps. Steph. Catal. p. 65. No. 676. 



Ovate, shining : head black, immaculate ; thorax with the disc "black, the sides 

 piceous or rufo-ferruginous : elytra pale ferruginous, obsoletely punctate- 

 striated, the interstices convex : body deep black beneath : antennas and legs 

 ferruginous : palpi luteous. 



The black patch on the disc of the thorax, and the pale ferruginous elytra and 

 legs, at once distinguish this from the following species. 



Two specimens of this insect I procured from the Marshamian 

 collection : of their locality I am ignorant. 



Sp. 51. atricapillum. Ovatum, nitidum, rufo-tesiaceum, capite piceo, elytris 

 testaceis, obsolete striatis, antennis pedibusque pallide testaceis. (Long. corp. 

 flin.) 



De. atricapillus. Marsham. — Ce. atricapillum. Steph. Catal. p. 65. No, 677. 



Ovate, glossy: head pitchy-black: thorax bright rufo-testaceous : elytra pale 

 testaceous, very obsoletely striated : abdomen rufo-testaceous beneath ; an- 

 tenna? and legs pale testaceous ; the club of the former dusky. 



This differs from the preceding by having the disc of the thorax immaculate, 

 and from the following by the paler hue of the head and its slightly dissimilar 

 form. 



Also obtained from the Marshamian cabinet, without a know- 

 ledge of its exact locality. 



Sp. 52. atriceps. Ovatum, nitidum, piceum, capite atro, elytris rufo-testaceis 



striatis, antennis pedibusque rufo-luteis. (Long. corp. ^ lin.) 

 Sp. atriceps. Kir by MSS. — Ce. atriceps. Steph. Catal. p. 65. No. 678. 



Ovate, shining, pitchy : head black : thorax bright glossy pitchy : elytra rufo- 

 testaceous, rather deeply punctate-striated, the interstices rounded and obso- 

 letely punctulated : antennae, legs, and palpi of a reddish-luteous. 



Differs from Ce. atricapillum by the deeper colour of the head and thorax, the 

 rufescent deeply striated elytra, and pale capitulum of the antennae. It is 

 not unlikely that this and the two foregoing insects may be the same species 

 in different degrees of maturity. 



Taken near Barham, where I had the pleasure of capturing my 

 specimen in September, 1821, when on a visit to my kind friend 

 the Rev. W. Kirby for the purpose of examining his collection, &c. ; 

 and taking notes for this work and my Catalogue. 



Sp. 53. lave. Ovatum, castaneum, nitidiuscidum, elytris punctato-striatis. (Long.

 De. lsevis. Marsham. — Ce. Iseve. Steph. Catal. p. 65. No. 679. 

 Ovate, slightly shining : of a deep castaneous, with the head nearly black :
