sutural margin, nigro-rcneous ; inflexed limb nigro-cyaneoiis, lon- 

 gitudinally concave, its outer margin verrucose. Mesosternal 

 spine stout, slightly longer than the metasternum. 



Separated from D. biremis by the narrow, less convex form and 

 by tlie coarser punctuation of the thorax and elytra.

Head opaque ; antennae half the length of the body, the five lower 

 joints nitidous, nigro-c?eruleous, the rest opaque black. Thorax 

 twice as broad as long ; sides straight and nearly parallel from 

 tlie base to beyond the middle, thence rounded and converging to 

 the apex, the latter submucronate ; upper surface rather finely 

 but distinctly punctured. Elytra oblong, rather strongly punc- 

 tured, the punctures arranged in double rows, confused on the 

 outer disk ; each elytron with four narrow angulose-undulate pale 

 yellow fascia3, the first at the extreme base, interrupted in the 

 middle and on the outer border, the second between the base and 

 the middle, abbreviated on the suture and at the outer margin, the 

 third across the middle itself, entire, and the fourth halfway be- 

 tween the middle and the apex, abbreviated at the suture, the last 

 very irregular and connected with several irregular concolorous 

 patches, which extend nearly to the apex of the elytron ; in addition, 

 on the middle disk of each elytron between the third and fourth 

 fasciae is a short semilunate yellow line ; on the outer margin, just 

 at the outer extremity of the apical fascia, is a small oblong red 

 spot, connected beneath with the concolorous third of the in- 

 flexed limb ; in some specimens are also several small spots of the 

 same colour, placed near the apex of the elytron. Mesosternal 

 spine strong, nearly equal in length to the metasternum.

* Since this paper was read, Mr. M. Jacoby, in the ' Proceedings of the Zoo- 

 logical Society' for the present year, p. 14G, has described this insect under the 

 name giyen above. My description being already in type, it was too late to 

 withdraw it.
