D. dathrata^ and the typical clathrata of De Cliaucloir's, represented by- 

 one example only in his collection, is a small male specimen in which the 

 outer, or fifth costais well defined, and the postical dot is more elongated 

 than usual; this postical whitish patch is often reduced to a mere 

 dot, and even disappears altogether in specimens captured in one 

 locality and at dijBPerent times of the year. The compression and 

 dilatation of the joints of the antennae vary alsoj in some examples 

 before me from Potchefstroora (Transvaal), they are almost sub- 

 foliated, although always in a lesser degree than in the two species 

 psoudO'Clathrata and graiidis, and also sub-filifi>rm or at least not 

 much dilated, in both sexes.

D. PSEUDO-CLATHRATA. new species. 



Metallic black with a greenish, golden tinge on the upper part, 

 dark metallic blue underneath ; antennae with the seven apical 

 joints compressed and sub-foliated outwardly ; labrum black with 

 a narrow median, yellowish longitudinal band, head strigose ; 

 prothorax quadrate, grooved in the centre, deeply impressed in front 

 and behind, the disk produced in two long protuberances, plicated 

 transversely; elytra ovate, very convex, ampliated at a little past the 

 middle, suture ending in two short spines on each side, each elytron 

 with six raised lines not sinuose, and of equal length reaching 

 from the base to three-fourths of the length, (the outer one disappears 

 below the humeral angle), the intervals between these raised lines 

 are closely plicated but not foveated, the posterior part is very rugose 

 and has on each side a long, marginal, white patch which does not 

 extend as far as the apex ; legs dark -blue with a bronze tinge. 



Length, 25; width, 8"^'"^- 



Allied to clathrata^ but the joints of the antennae are much more 

 compressed, the elytra are not so suddenly ampliated past the 

 middle, and are therefore moi'e ovate, the raised lines, six in number
