ENGIDiE. — ATOMARIA. 67 



The glossy castaneous hue of this species, with its oblong-ovate, and convex > 

 form, distinguish it from its congeners. 



Not uncommon near London ; also found in Norfolk, Suffolk, 

 Devonshire, &c. 



Sp. 10. nigripennis. Ovata, convexa, rufo-testacea, nitida, glabra, elytris punc- 

 tatis nigris, abdomine rufo-piceo. (Long. corp. 1 lin.) 



De. nigripennis. Paykul— At. nigripennis. Steph. Catal. 84. No. 906. 



Ovate, convex, shining rufo-testaceous, glabrous, the elytra punctate and black, 

 the abdomen pitchy-red ; legs and antennae ferruginous. 



The deep-black elytra and bright rufo-testaceous thorax serve at once to distin- 

 guish this pretty species. 



Not common : taken occasionally within the metropolitan district, 

 and in Norfolk and Suffolk. 



Sp. 11. mesomelas. Ovata, convexa, nigra, pubescens, elytris testaceis basi de- 

 terminate nigris, antennarum basi pedibusque rufo-testaceis. (Long. corp. 

 f lin.) 



De. mesomelas. Herbst. — At. mesomelas. Steph. Catal. 84. No. 907. 



Ovate convex, black, pubescent, the elytra testaceous, with the base distinctly 

 black for about one-third of their length ; the antennae and legs pale rufo- 

 testaceous, the club of the former dusky. 



Slightly variable : in some examples the anterior margin of the thorax is ru- 

 fescent; others have the black at the base of the elytra extending considerably 

 towards the apex, and the latter is sometimes fuscous. 



This and the following differ from their congeners in having the elytra more or 

 less testaceous, or yellow, at the apex, the base being black ; and the capitulum 

 of the antennae dusky. 



Found in damp situations near London : not very common. 



Sp. 12. dimidiata. Oblongo-ovata, subconvexa, punctulatissima, nigro-fusca, 

 elytris dimidiato-Jlavis. (Long. corp. f — 1 lin.) 



Co. dimidiata. Marsham. — At. dimidiata. Steph. Catal. 84. No. 908. 



Oblong-ovate, slightly convex, very thickly punctured, of a deep fuscous-black, 

 with the apical half of the elytra yellow, or ochraceous : legs testaceous ; an- 

 tennae with the club fuscous. 



More elongate than the foregoing, of which I suspect it may be only a variety, 

 or the opposite sex :— it is in general rather larger. 



Inhabits the metropolitan district. I have also obtained it from 

 the neighbourhood of Bristol. 



Sp. 13. atra. Ovata, convexa, nigra, pubescens, elytrorum apice antennis pedi- 

 busque rufo-ferrugineis, thorace postice latiore. (Long. corp. \ — | lin.)
