Genus CCXIV. — Buprestis Auctorum. 



Antenna? subfiliform, serrated in both sexes, basal joint elongate, subclavate, 

 terminal one minute. Palpi, maxillary subfiliform, the terminal joint slightly 

 tumid ; labial minute : labrum attenuated and slightly emarginated in front : 

 mandibles slightly bifid at the apex: maxilla; small, somewhat bilobed at 

 the tip : head deflexed, short, retuse : thorax with the posterior margin 

 closely applied to the base of the elytra; the latter elongated, trigonate, 

 entire, or serrated : legs slender ; tarsi with the penultimate joint bilobed. 



The genus Buprestis may be known from Agrilus by the greater 

 width of the body, the thickening of the terminal joint of the 

 maxillary palpi, the attenuated labrum, the elongate basal joint of 

 the antennae, bifid mandibles, &c. 



Whether all the following species are truly indigenous re- 

 mains questionable ; but doubtless some are aboriginal natives, and 

 as all those which are hereafter given as British are introduced 

 from the inspection of specimens captured at large — and, as the in- 

 sects are, moreover, found in similar latitudes on the continent — 

 no material injury to science can arise should their native origin 

 prove ultimately to be erroneous. 



A. With the elytra dentate, or serrate, at the apex, 

 a. With the outer tip of the elytra serrate. 

 Sp. 2. rutilans. Aurco-viridis, elytris striatis, viridibus nigra maculatis, mar- 

 gine aureo. (Long. corp. 7^in.) 



tSp. 1. chrysostigma. Purpurascenti-umea, thorace ina>(juali rugoso, elytris 

 obscuris elevato-costatis, viargine maculisque duabus disci rubro-aiireis im- 

 pressis. (Long. corp. 6i lin.)
