what coarsely punctate-striated, the striae regular : the body black beneath : 

 legs and antennae pale testaceous, the latter palest. 

 I obtained a pair of this insect from the Marshamian cabinet named as above. 



Also found near London, and I believe in Suffolk and Norfolk. 

 I have one specimen from the west of England. " Habitat in 

 Scotia.'* — Germar. 



Sp. 6. rufimarginatus. Brevis, lotus, piceo-niger, thoracis laterihus pedibusque 



rufis, elyiris profunda crenato-striatis. (Long. corp. § lin.) 

 Oc. rufimarginatus mihi. Steph. Catal p. 58. No. 581. 



The comparative brevity and superior width of this species sufficiently point 

 out its distinction : it is of a pitchy-black : head glossy, obscurely punctured, 

 with some larger impressions on the crown : thorax rather convex, the lateral 

 margins broadly rufous; the disc with an abbreviated longitudinal channel 

 and an obsolete transverse arcuated impression on each side towards the base ; 

 elytra slightly glossy-black, rather pitchy or rufescent toward the apex, mo- 

 derately convex, and somewhat deeply crenate- striated, the striae reaching to 

 the apex : legs rufous : antennae and palpi rufescent, with the tips dusky. 



My specimens occurred near London. " Netley."— Rev. F. W.

Sp. 7. nanus. Niger, obscurus, thorace subfoveolato, elytris tenue punctato- 



striatis > pedibus rufo-testaceis. (Long. corp. ^ — f lin.) 

 Oc. nanus mihi. Catal. Steph. p. 56. JVo. 582. 



Very minute: deep obscure black; the head and thorax slightly glossy, the 

 former nearly smooth anteriorly, foveolated on the crown ; the latter with a 

 slight dorsal channel and two shallow foveae on each side between it and the 

 lateral margins : elytra faintly punctate-striated, the punctures somewhat re- 

 mote : legs, antennae, and palpi testaceous, the former with a rufous tinge. 



The locality of this minute insect I do not remember, but it 

 was not found in the metropolitan district. " Southend." — Rev. 

 F. W. Hope. 



Sp. 8. aeratus. Splendide asneo-niiens, thorace, dorso canaliculato, disco foveolato,

Of a brilliant glossy brass, obscurely tinged with cupreous : head smooth an- 

 teriorly, with the crown somewhat rugose, and foveolated : thorax smooth,

 which is considerably depressed and has another fovea placed anteriorly:
