Atheta terminalis, GTrav. 

 Eelated to A. elongatida and its allies, but differing from them all in 

 having the last joint of the antennae larger and longer, being twice as long as 

 the tenth, and the antenna? are more thickened towards the apex, the penulti- 

 mate joints being distinctly transverse. The thorax is often reddish brown, 

 the elytra reddish yellow, and the antennae pitchy red with the base yellow. 

 It resembles A. gyllenhali in having the elytra together about as long as broad, 

 but it is smaller, and the elytra are more strongly punctui'ed. The last ventral 

 segment of the hind body in the c? does not project as much as in A. elongatida. 

 Length, 2'5 — 3'2 mm. 



One specimen in Mr. Champion's collection from Gosport, Hants. 

 A. tricolor, Steph. is given as a synonym of this species in the last 

 European catalogue, but it seems more than doubtful that this 

 is correct.

 BY MALCOLM CAMERON, M.B., R.N., F. E.S. 



Atheta (Microdota) doderoi, n. sp. 



Black, shining ; head, thorax and elytra distinctly shagreened, distinctly 

 but superficially and sjjaringly punctured. Elytra transverse, not longer than 

 the thorax. Antennaj and legs testaceous. Length, 1-6 — 1-8 mm. 



Very closely allied to A. segra, from which it is distinguished by its shorter

 and pvmcturation of the fore parts, wliich are less shining, tlie black colour, and
