male. The specimen named duplex is a little narrower than the 

 other female examples, but is clearly the same species ; the alter- 

 nate interstices of the elytra are a little more distinct than the 

 others.

This species is closely allied to D. pubicomis, but has the thorax 

 black and rather shining, deeply impressed on each side. The alter- 

 nate interstices of the elytra are slightly costiform, the others are 

 extremely narrow and somewhat obscured, and interrupted by the 

 rather strong punctuation of the striae. 



( '» letes scabripennis, Motsch. (Bull. Mosc, 1861, i. p. 137), belongs 

 to this genus, and should come here. It is much smaller than any 

 of the preceding (lf-2| lines long), and has the elytra pale yellow, 

 with the apex black. The thorax has a fovea in the middle at the 

 base, and is impressed on each side. The elytra hare the striae 

 rather more finely punctured than any of the preceding species; the 

 alternate interstices are slightly elevated, the others are very narrow 

 and somewhat interrupted by the punctures of the striae. 



The male has the branches of the antennal joints slender, a little 

 longer than the joints themselves. The female has the antennae 

 rather strongly serrate. 



The specimens in the Museum are from Ceylon.

Very close to D. scabripennis, Mots., but the antennae, compared 



with the female, appear rather more dentate, the thorax is si raighter 

 at the sides, and the punctuation of the stria? of the elytra is rather 

 stronger and the interstices are all equal.
