HARPALID.^i:.— ANCHOMENUS. 81 



count has been recently given, in which the uniarticulate structure 

 of the internal maxillary palpus is, I believe, first noticed : this 

 character, combined vi^ith the punctate thorax, distinguishes this 

 genus from Platynus and Anchomenus, which latter it is frequently 

 associated with by the continental entomologists; and the simple 

 lobe in the centre of the notch of the mentum discriminates it from 

 Epomis and Chlsenius, with which it agrees in having a punctate 

 thorax and pubescent elytra.

No. 113. 



Bluish-black : head dusky-blue or greenish, strongly punctate : thorax ferru- 

 ginous, a little convex and pubescent, finely punctate ; a deep channel down 

 the middle, and a slight impression on each side near the hinder angle : the 

 scutel and elytra yellow, the latter slightly pubescent, very obsoletely striated, 

 reddish towards the suture, with a small roundish spot at the basal angle, a 

 second larger, and transverse, towards the middle, reaching nearly to the 

 suture, and a third at the tip, united externally to the central one : beneath 

 the body is bluish-black ; the thighs and tibiae are yellowish at the base, and 

 dusky at the tip, the tarsi brownish : the mouth, palpi, and two basal joints 

 of the antennsB are ferruginous, the rest of the antennae dusky. 



Kent seems to be the principal habitat of this beautiful and de- 

 licately formed species, most of the specimens contained in our 

 cabinets having been captured in that county, chiefly in the eastern 

 division, near Dover, whence I have received two. In the British 

 Museum are others from the same locality. A specimen was picked 

 up by a lady last October, at Petrixbourne, near Canterbury. 



Genus XXXII. — Anchomenus, Bonelli. 



Palpi with the terminal joint ovate, attenuated at the tip, slightly truncate : 

 labrum quadrate, transverse, entire: mandibles denticulated at the base, 

 acute: mentum anteriorly emarginate, with an acute simple tooth in the 

 centre. Antennoe linear, the third joint twice as long as the second : head 

 subovate : thorax truncate-cordate, sUghtly convex, scarcely margined : elytra 

 rather sinuated at the apex : body a Uttle convex : wings two or none : an- 

 terior tarsi of males with three dilated joints. 



Anchomenus is readily known from Callistus by the form of the 

 thorax, which is rather elongate and not punctate throughout ; and 

 from Platynus by having an acute simple notch in the centre of the 

 mentum, and the body rather convex.
