Melasis OLIV. Last joint of palps large, globose. . Antennae of 

 males pectinate. Tarsi slender. 



Note. We omit here several sub-genera, to be inserted between the 

 genera Slater and Buprestis. 



Buprestis L. Antennae inserted between the anterior part of 

 eyes, serrate, with short teeth. Mandibles short, triangular, with 

 apex simple. Palps filiform. Head retracted within thorax nearly 

 as far as the posterior margin of eyes. Thorax trapeziform, broader 

 posteriorly. Scutellum small or none. Tarsi with first four joints 

 dilated, bilobed.

Sp. Buprestis gigantea L., VOET Coleopt. i. Tab. 48, fig. i, SULZEB Kennz. 

 der Ins. Tab. VI. fig. 38 ; 2" 3'" long ; green copper-coloured ; the feet 

 steel-blue ; the shield-covers terminating in two points ; South America. 

 Bupr. fulminans FABR., i" 10'" long, green shining, the elytra striped 

 longitudinally with fine points, with ten fine teeth at the apex as though 

 serrated, and a red copper-coloured spot ; very common in Java. In 

 southern Africa many species are found, which are beset with little bundles 

 of hairs on the shield-covers, as Buprestis fascicularis L. In Europe, 

 of this numerous genus 1 there are met with comparatively only few and 

 smaller species. The larvae live in bark and wood of trees ; they have no 

 feet, are elongate, flat and distinguished by the breadth and size of the 

 first ring of the body next the head. 



Sub-genera : Trachys FABR., Aphenisticus LATH., Buprestis LATE. 

 (Agrilus MEGERLE and many sub-genera proposed by ESCHSCHOLTZ, 

 SOLIER, DE LA PORTE, and GORY, &c.)

 more than 1500 species of this genus, Diet. univ. d'Hist. not. n. p. 779.
