54 Mr. Joseph S. Baly on the 



apex in front ; disk convex, smooth and shining, rufo-testaceous. 

 Elytra broadly ovate, dilated posteriorly, convex, grooved below 

 the humeral callus, the subhumeral costa elevated and extending 

 to a short distance below the middle ; surface rather closely punc- 

 tured ; outer margin rather broadly reflexed. 



Separated from D. Westwoodi by its broader and more 

 ovate form, the subhumeral groove being also less deeply 

 impressed.

Head triangular, not longer than broad, shining black, a patch 

 on the vertex, together with the clypeus, the longitudinal ridge 

 and the anterior margin excepted, flavous ; antennae filiform, more 

 than four-fifths of the body in length, the second and third joints 

 short, nearly equal, the fourth much longer than the preceding 

 two united ; the four lower joints piceo-fulvous, the fifth piceous, 

 the following three, together with the apical one, black, the ninth 

 and tenth yellowish white. Thorax about one-third broader than 

 long ; sides rounded anteriorly, parallel and slightly sinuate behind 

 the middle; disk nitidous, convex, impunctate. Elytra oblong- 

 ovate, dilated posteriorly, convex, strongly plicate below the 

 humeral callus, the subhumeral costa strongly elevated and ex- 

 tending downwards below the middle, general surface minutely 

 but rather remotely punctured ; each elytron with a narrow sutural 

 line, abbreviated just below the middle, and a linear vitta, which 

 runs along the subhumeral costa and extends downwards a little 

 beyond the medial line, black. 



The yellow colour of the face in some cases extends 

 upwards on the front ; the subhumeral ridge is more 

 strongly developed than in any of the allied species.
