D. Natalica. new species. 



Colouring and size of the preceding species, the female, however, of 

 a more light-bronze sheen, head and prothorax similar ; elytra of the 

 male elongated, plane on the back, with the apical spines moderately 

 long:, sharp, and straight, those of the female very convex, the apical 

 part hardly divaricating and without any spines, set with broad, some- 

 what reticulated, deep punctures, and having on each side five raised 

 smooth lines ; the first one near the suture does not reach the base, 

 and disappears after the median part of the disk, the two discoidal 

 ones unite at a short distance from the base, run parallel to one 

 another and reach about to three-fourths of the length, and the fourth 

 and fifth stop short of the apex ; on each side is an elongated white 

 patch, sometimes missing. 



Length, 19-22 ; width, 4-8"'-'"- 



Although the male, or at least what I conjecture to be the male, is 

 hardly discernible from sculpturata, the only difference being in the 

 first dorsal carina very short in the anterior part, and the two dorsal 

 ones which are longer than in sculpturata, the female is very distinct 

 owing to the convex form of the elytra, the first dorsal carina is also 

 not so well defined, nor does it reach so far towards the apex.

Brassy with a golden tinge ; head strigose, labrum black with a 

 median yellowish band ; prothorax irregularly plicated, quadrate, with 

 the discoidal protuberances much raised ; elytra oblongo-ovate, con- 

 vex, covered with broad punctures, and the apical, sutural parts pro- 

 duced in very sharp spines ; they have on each side four acute 

 raised lines placed at the same distance from one another, and disap- 

 pearing before reaching the apex, on the outer margin there is a sub- 

 humeral white spot, a post median one, rounder than the sub-humeral
