76 Mr. T. V. Wollaston's Revision of 



Sp. 16. Atomaria hasalis. 

 Atomaria basal'is, Erich., Nat. der Ins. Deuts. iii. p. 391 (1848). 

 The rather broad, oblong-ovate form, and thickly punctured, 

 pubescent surface, of the A. basalis, in conjunction with the pecu- 

 liarity of its colouring, — which is of a dull black, the apical two- 

 thirds of its elytra being rufo-testaceous (with the line of demar- 

 cation between the light and dark portions Ill-defined), — will at 

 once distinguish it from its allies. Occasionally more than two- 

 thirds of the elytra are testaceous, leaving only their extreme base 

 suffused with a darker tint. I possess a series of this insect taken 

 by myself about twelve years ago; but whether at Cambridge, or 

 on the Cotswold Hills of Gloucestershire, I cannot at present (hav- 

 ing failed to make a note at the time) recal. I have seen spe- 

 cimens, however, which were captured by Mr. Murray, near 

 Edinburgh. It is unrepresented in the Stephensian collection, 



Sp. 1 7. Atomaria munda. 

 Atomaria munda, Erich., Nat. der Ins. Deuts. iii. p. 388 (18 i8). 

 Well distinguished by its oblong-ovate form, finely punctulated 

 surface, by its more or less rufescent, or piceo-rufescent, hue, and 

 by the deep central transverse impression at the base of its pro- 

 thorax, — the impression being at either extremity terminated by 

 a short raised costa, or ridge. It is exceedingly rare ; and, like 

 the last, unrepresented in Mr. Stephens's cabinet. I have not, 

 myself, ever met with it, but possess a specimen from the north of 

 England ; and I have seen others, in the collection of Mr. Water- 

 house, which he captured at Southgate, near London. 



S. III. — Body more or less ovate ; prothorax usually somewhat pro- 

 duced behind {in front of the scute Hum), and less distinctly 

 margined along its posterior edge. 



Sp. 1 8. Atomaria nigripennis. 

 Dermestes nigripennis, Payk., Fna Suec. i. p. 292 (1798). 

 Atoynaria nigrij)cnnis , Steph., 111. Brit. Ent. iii. p. 67 (1830). 



Erich., Nat. der Ins. Deuts. iii. p. 390 (1848). 

 Immediately known by its convex, ovate form, bright, subgla- 

 brous, lightly punctured surface, and by its rufous head and pro- 

 thorax, — the latter of which is broadly margined towards its pos- 

 terior angles, and with a deep transverse impression behind, the 

 impressiori however having scarcely any indication (even beneath
