154 MANDIBULATA. — COLEOPTERA. 



Rather depressed: shining black; above rich glossy blue; thorax with the 

 dorsal channel deep in front, and united to a transverse impression anteriorly, 

 the base somewhat rugose, with a shallow, broad, and rugged fovea near the 

 hinder angles : elytra deep blue, striated, the striae impunctate and deep, the 

 margin obsoletely punctate; the usual abbreviated stria rather long: legs deep 

 pitchy-black; claws rufous: antennae fuscous, with the basal joint rufous 

 beneath : palpi pitchy-black, with the tips ferruginous. 



I liave seen but one specimen of this fine species, which I obtained 

 from Mr. Marsham's collection. 



Sp. 39. poeciloides. Plate VIII. f. 5. Paulo convexus, niger nitidus, supra 

 splendide viridis, antennarum articulo basali inferne rufo, thorace postice 

 rugoso utrinque sub bifoveolato. (Long. corp. 5 — 5^ lin.) 



Ha. poeciloides mihi. — Steph. Catal.p. 31. No. 287. 



Slightly convex : glossy black, above brilliant rich green : thorax as in the last, 

 but more rugose posteriorly, and the foveolae more distinct, with an obsolete 

 one near the union of the lateral and posterior margins : elytra rich green, 

 deeply striated, the strife impunctate, the margin with a continuous series of 

 impressed dots : legs pitchy-black, claws fulvous : antennae fuscous, with the 

 basal joint rufous below : palpi pitchy-black, with the tips fulvous or ferru- 

 ginous. Female more obscure and aeneous above. 



The resemblance of this species to Poecilus cupreus is so close, that were it not 

 from the dilatation of the intermediate tarsi, and the roundedjposterior angles 

 of the thorax, it might readily be confounded with that insect, which has in- 

 duced me to give it the above name, which I have retained, although I have 

 recently ascertained that it is synonymous with the Ha. virens, De Jean MSS. 



Two indigenous specimens only have come under^ my notice ; 

 they were taken on the shores of the Thames several years since. 



Sp. 40. scaritides. Niger nitidus, antennis, palpis, tarsisque piceo-hrunneis, thorace 

 postici utrinque foveold punctata. (Long. corp. 4 j hn.) 



Ha. scaritides. Sturm. — Steph. Catal. p. 31 . No. 288. 



Shining black : thorax with an obsolete dorsal line, the sides rounded and pos- 

 teriorly suddenly attenuated, the hinder angles nearly obliterated, with a 

 punctate subtriangular fovea on each side at the base : elytra simply and rather 

 faintly striated : legs black : tarsi pitchy-brown : antennae and palpi the same, 

 but rather pale. 



Of this insect I have also seen but my own specimen, which was 

 taken on the shores of the Thames beyond Gravesend. 



** AntenncB very short. 

 Sp. 41. vernalis. Nigro-piceus, subnitidus, antennis palpisque pallidis, pedibus 



fusco-ferrugineis, thorace utrinque uni-foveolato. (Long. corp. 2| — 3 lin.) 

 Ca. vernaUs. Buftschmid. — Ha. vernahs. Steph. Catal. p. 31. No. 289. 



Pitchy-black, rather shining : thorax very short, with an obsolete dorsal channel, 

 and near the base on each side with a simple minute obsoletely punctate im-
