BUPRESTID7E. — AGRILUS. 239 



Genus CCXV. — Agrilus, Megerle. 



Antenna; serrated in both sexes ; the basal joint short, somewhat angulated at 

 the base; the two following also short, and of nearly equal length; the re- 

 mainder produced internally. Labrum quadrate, slightly emarginate : man- 

 dibles triangular, stout, somewhat acute : palpi, maxillary with the terminal 

 joint longest, ovate, truncate, not dilated ; labial with the terminal joint long, 

 acute: head retuse, not emarginated : thorax cylindric, quadrate, produced 

 in the middle behind : scutellum transverse : elytra very long, subulated, 

 slightly serrated at the apex : abdomen stout : legs rather slender ; femora 

 slightly incrassated; tarsi with the fourth joint bilobed. 



Agrilus appears to differ chiefly from Buprestis by its cylindric 

 form of body, short basal joint of the antennae, quadrate labrum, 

 simple mandibles ; slender, somewhat attenuated, terminal joint of 

 the maxillary, and elongate conic terminal one of the labial, palpi ; 

 quadrate thorax, &c. 



A. With the body elongate-linear, acuminate. 



Sp. 1. biguttatus. Cceruleo-virescens, f route impressd, elytris puncto postico 



impresso albo-villoso, abdomine albo-punctato. (Long. corp. 4 — 8 lin.) 

 Bu. biguttata. Fabricius.—Ag. biguttatus. Steph. Catal. 120. JVo. 1216. 



Very brilliant blue- or bronzed-green above : head rugose-punctate, with a deep 

 impression on the forehead : thorax with the disc convex, unequal, transversely 

 rugulose, with a rounded impression in the middle, and another near the base 

 before the scutellum, the sides depressed ; elytra depressed on the back, thickly 

 granulated, with a large deep fovea at the base, and towards the apex of each, 

 near the suture, a small white villose spot : abdomen shining blue-green, with 

 three or four brilliant white villose spots on each side : legs and antennae blue- 

 green, or bronzed. 



Colour above very variable, being of various tints of blue, green, bronzed or 

 slightly cupreous. 



Not common; though frequently observed at Darenth-wood, 

 where I have at different times taken eight or ten examples in 

 June : it flies with great facility, and delights in settling upon felled 

 timber in a hot day. " Cuckfield." — Rev. F. W. Hope. 



Sp. 2. viridis. Viridi-aeneus,fronte cojivexti, thorace brevissimo transverslm im- 

 presso, postice angustiori trisinuato. (Long. corp. 2f — 3^ lin.) 

 Bu. viridis. Linnc.—Don. v. pi. 174.— Ag. viridis. Steph. Catal. 120. No. 1217.
