interstice and the suture; the sutural interstice ends in a 

 minute spine; each elytron with ten regular striae of 

 punctures which are larger in the 5 th and following striae; 

 those punctures of the 4 th stria which are placed between 

 the black spot and the black apical half are very minute 

 and situated in a yellowish spot which occupies the 4 th — 6 th 

 interstices just before and touching the black apical half ') ; 

 the interstices are impunctate; the 1 st (sutural), 3 rd , 7 th 

 and 9 th interstices are distinctly raised on the apical 

 portion, the two latter faintly so from beyond the shoulder; 

 the 3 rd and 9 th interstices extend to the apical margin. 



Under surface: the triangular middle portion of the 

 head is sparingly covered with fine but distinct punctures, 

 the lateral portions are more strongly punctured ; the 

 sterna show some large punctures laterally and the elytral 

 epipleurae some fine punctures along the inner margin of 

 the basal fourth. Ventral segments with a single hair- 

 bearing puncture on both sides of the middle, the apical 

 segment broadly subtruncate posteriorly. Legs simple.

 middle of the pronotum, the lateral and basal edges of 

 the prothorax, the scutellum, the basal edge and the apical 

 half of the elytra, as well as a stripe between the 3 rd

2) I am informed by Prof. Kolbe that the indication «Zanzibar" as the

 specimens to the Berlin Museum, having made his collections in Usainbara, 

 f. i. at Bondéi.
