HARPALIDiE. — AMARA. 133 



equally rounded ; the base obsoletely wrinkled longitudinally at the extremity 

 of the dorsal channel^ and very obsoletely punctate towards each angle^ but 

 without any impression : elytra simply striated, with a continuous series of 

 impressed dots on the margin : legs pitchy, with the tibiee and tarsi some- 

 what ferruginous ; the anterior tibiae with the apex dusky. 



Found near London. 



Sp. 19. laticoUis. ^neo-picea, supra cenea, thorace latissimo, lavissimo, im- 



jmnctato, antennis pedibusque piceis. (Long. corp. 3^ lin.) 

 Am. laticollis viihi. Steph. Catal. p. 27. No. 232. 



Readily discriminated by the breadth of the thorax, which is totally impunctate 

 throughout, having no other impression on its surface than the usual dorsal 

 channel, and that somewhat obsolete: the upper part of the body is of a 

 bright glossy brass, slightly tinted with copper, sometimes entirely black 

 above : the elytra are rather faintly striated, the striae impunctate with an 

 interrupted series of rather distant impressed dots on the margin. 



I have seen two specimens only of this species, both of which 

 were captured near London : one is in Mr. Hatchetfs collection ; 

 the other in my own. 



Sp. 20. communis. Ovalis, nigra, snprh virescenti-cBnea, antennarum basi 

 tibiisqueferrugineis, thorace lato, postice vix foveolato. (Long. corp. 3 — 3g 

 lin.) 



Ca. communis. Fabricius. — Am. communis. Steph. Catal. p. 27. No. 233. 



Allied to the few preceding species, but comparatively shorter and wider : above 

 generally greenish-brass or coppery: head glossy, smooth: thorax broad, 

 closely applied to the elytra, smooth, shining, a little convex, with a faint 

 dorsal channel, the base very obsoletely punctulate towards the angles, which 

 have mere rudimentary foveolae : elytra short, broad, a little convex, faintly 

 striated, the striae scarcely punctulate; an interrupted series of impressions 

 on the margin: body beneath bronzed-black, smooth, the sides obscurely 

 punctulated : thighs glossy-black, tibiae pale ferruginous, tarsi dusky : antennae 

 with the three basal joints rufous, the rest dusky : mouth and palpi black. 



Var. /3 Am. cognata. Steph. Catal. p. 27. iVo. 230. — Rather larger, with the thorax 

 very obsoletely punctate at the hinder angles, and the foveolae obliterated. 



Extremely common beneath stones, and in gravel-pits, throughout 

 the metropolitan district: also at Bottishamj Kimpton, &c. 



Sp. 21. famiharis. Brevis, ovalis, nigra, supra nigro-cwrulescens, antennarum 

 basi pedibusque totis rufo fcrrugineis, thorace postice obsolete Jbveolato. (Long, 

 corp. 3— 3^ lin.)
