cate as the prosternum, sparsely punctured at the middle: first ventral segment broadly 
sulcate, sparsely punctured at the middle: last ventral segment with two narrow coste,

The following species belonging to the genus is unknown to me: 
24. D. Lecontei, ‘cinereo-argentata, thorace inzequali, elytris punctatis, maculis nigro-velutinis.’ Long. -33. 
Buprestis Leconte’ Gory, Mon. Buprest. 4, 107, tab. 18, fig. 104. 
D’un cendré argenté. Antennes cuivreuses. Téte finement ponctuée, avec de petites 
élévations irreguliéres, et recouverte d’une pubescence argentée. Corselet presque carre, 
avec ses angles postérieurs trés aigus, couvert d’élévations irréguliéres, dont la plus forte 
est sur son milieu, avec une profonde impression dessus. Llytres granuleuses, avec des 
rangées de points disposés en lignes longitudinales, qui les font paraitre striees, surtout 
pres de la suture: elles sont rebordés prés de leur base, et ont en outre quelques taches 
dun noir velouté. Cette charmante espéce . . . . doit étre placée aprés la Punctulata.’
