infra basin, duobus prope medium duobnsque ante apicera, 

 fulvis ornatis.

Head granulose, distinctly punctured ; labrum rufo- 

 piceous. Thorax more than twice as broad as long; sides 

 straight, converging from the base towards the apex, 

 abruptly rounded at the latter, the anterior angles strongly 

 mucronate, the hinder ones acute ; disk faintly excavated on 

 either side, granulose, subopaque, impressed with round 

 shining punctures, rather larger and more crowded at the 

 sides than on the middle disk. Elytra broader than the 

 thorax ; sides subparallel from the shoulder to below the 

 middle, thence obliquely converging and conjointly form- 

 ing at the apex a distinct angle ; above convex, gibbous 

 just before tlie middle, thence obliquely deflexed to the 

 apex ; surface subopaque, rather strongly punctured, the 

 punctures arranged in irregular longitudinal strise, inter- 

 spaces granulose ; each elytron with six slightly-raised, 

 shining, impunctate fulvous spots, two at the base, the 

 first on the humeral callus, extending upwards to the 

 basal margin, the second rather lower, placed near the 

 suture ; two placed obliquely about the middle, one on 

 the outer, the other on the inner disk ; and lastly, two 

 others, also obliquely placed halfway between the middle 

 and the apex ; these spots standing exactly under each 

 other, form two longitudinal rows on each elytron. 



Very nearly allied in form and coloration .to D. hrun- 

 neipennis, Jacoby, but scarcely more than half the size, 

 more strongly punctured, and easily to be separated by the 

 fulvous spots in the elytra, which, being slightly thick- 

 ened, shining and impunctate, stand up in strong contrast 

 to the opacity of the general surface. In one of my speci- 

 mens of D. hrunneij)ennis I find very faint indications of 

 spots arranged in a similar manner, but they are not 

 thickened, and are subopaque and sculptured in a similar 

 manner to the rest of the disk.
