146 MANDIBULAR.— -COLEOPTERA. 



faintly punctate-striated, the interstices impunctate : legs and antennae pitchy- 

 chestnut : palpi dusky. 

 Broader and of a deeper colour than the next species, which greatly resembles 

 it: — they are both somewhat similar in form to Ce. haemorrhceum and its 

 affinities, but considerably smaller. 



I obtained a single example of this insect from Mr. Marsham's 

 collection ; and have since procured others that were taken near 

 London. 



Sp. 33. convexior. Oblongo-ovatum, atrum, nitidum, elytris apice tarsisque 



rufo-castaneis. (Long. corp. ^ — | lin.) 

 De. convexior. Marsham MSS. — Ce. convexior. Steph. Catal. p. 64. No. 659. 



Oblong-ovate; deep glossy-black: head and thorax immaculate, finely and 

 thickly punctured: elytra rather deeply punctate-striated, the interstices a 

 little elevated and punctulated ; deep shining black, with the apex distinctly 

 bright castaneous : femora and tibiae dusky piceous, the latter palest, or some- 

 times rufescent ; tarsi light castaneous-red : antennae and palpi rufous. 



Not so broad as the last, more glossy, the elytra more deeply-striated, and the 

 interstices punctured. 



I also obtained this species from the Marshamian cabinet; and 

 have since procured other specimens captured near London. 



Sp. 34. convexiusculum. Oblongo-ovatum, subconvexum, atrum, nitidum, elytris 

 tenue punctato-striatis apice obscure piceo. (Long. corp. f lin.) 



De. convexiusculum. Marsh. MSS. — Ce. convexiusculum. Steph. Catal. p. 64. 

 No. 660. 



Oblong-ovate, slightly convex, deep shining black ; head and thorax immaculate, 

 punctulated : elytra rather depressed, faintly punctate-striated, the interstices 

 nearly flat, obsoletely punctured; deep pitchy-black, the apex obscurely 

 piceous : legs dull castaneous-red, the femora rather dusky : club of the an- 

 tenna? and palpi black. 



Somewhat less than the last, the elytra more depressed, faintly striated, the in- 

 terstices nearly fiat, scarcely punctulated, and palpi black. 



From the Marshamian cabinet : it occurs near London. 



Sp. 35. nigrinum. Subconvexum, obscure subameum, elytris obsoletissime striatis t 



inter stitiis obsolete punctatis pedibusque nigris, (Long. corp. f lin.) 

 De. nigrinus *. Mus. Marsham. — Ce. nigrinum. Steph. Catal. p. 64. No. 661. 



* This insect is not the Dermestes nigrinus of Entomologica Britannica, which 

 has been erroneously given as a synonym for Hydrobius Seminulum : the De. 

 nigrinus of Marsham, of which I possess the original specimens, being Lim- 

 nebius nigrinus of my Catalogue ; the species described as De. nigricans, in 

 p. 121, by a typographical error.
