 pectore tarsisque piceo-tinctis, scutello antennisqne extrorsum

Long. 3^ lin. 



Hah. Colombia. A single specimen in my own 

 collection. 



Head not longer than broad ; clypeal ridge ill-defined ; antennte 

 filiform, scarcely three-fourths the length of the body, the second 

 joint short, the third scarcely longer than the second, the fourth 

 longer than the preceding two united; the three lower joints con- 

 coloroiis with the head, the following four stained with piceous, the 

 remaining four black. Thorax scarcely one-third broader than 

 long; sides parallel and distinctly sinuate behind the middle, 

 obliquely converging towards the apex anteriorly, the anterior 

 angle slightly produced laterally into an obtuse tubercle ; above 

 convex, nitidous, faintly excavated and obsoletely trifoveolate on 

 the hinder disk. Elytra ovate, slightly dilated posteriorly, convex, 

 subnitidous, closely and rather deeply punctured, not plicate l)elow 

 the humeral callus, the outer limb very narrowly edged with pale 

 green. 



Very similar in colour to D. Lehasii : separated by 

 the less deeply foveolate disk of the thorax, by the 

 absence of any plication on the outer side of the elytron, 

 and by the different coloration of the antennae.
