COSMEMA MIKANDA. 



Bronze, with a green sheen on the head and prothorax, dark blue- 

 black underneath ; labrum white narrowly marginated with black, 

 and slightly infuscated at the base; head strigose; prothorax short, a 

 little broader in front than behind, where it is nearly as broad as long, 

 deeply impressed transversely in the anterior and posterior part, each 

 side of the disk slightly raised, plicate with the folds very irregular ; 

 elytra elongato-ovate, ampliated past the middle, moderately convex, 

 but broadly depressed on each side of the suture, closely but not 

 deeply punctured, bronze, with the depression on each side of the 

 suture a brilliant green sheen, and with a supra-marginal narrow 

 white line reaching from base to apex, and emitting past the middle 

 a short slanting spur ; sutural spines short, moderately long ; legs 

 glowing red. Length 15 mm. ; width 5 mm. 



Hab. Orange Free State (Ventersburg) . 



The f acies is that of C. marginella and C. connexa ; the depression 

 on each side of the suture is well defined, as in the last-named 

 species ; the sculpture of the elytra is the same ; the spur emitted 

 inwardly is not unlike that of G. hmnata, but it is more slender and 

 also a little shorter, 



CoSMEMA ASPEEA. 



In shape, size, and sculpture this species is very closely allied to 

 G. miranda, the shape and sculpture of head and prothorax is 

 the same ; the labrum is yellowish white in both sexes, but the 

 difference between the two is found in the sculpture of the elytra of 

 the female, which are a little more roughly punctured, and thus 

 appear more rugose from the suture to the outer side, while in G. 

 miranda the space with the green sheen on each side of the suture 

 is so equally punctured as to give it the appearance of being closely 

 and transversely plicate (this is probably the cause of the dorsal 

 shining green bands) ; the dorsal juxta-sutural part is also more 

 depressed in G. miranda than in the present species, in which the 

 suture is also much more acutely raised ; it is also more convex 

 from the median part towards the apex ; the colour is the same, 

 but there is no greenish sutural band ; the supra-marginal lateral 

 yellowish-white band is slightly broader than in G. miranda, and 

 the inward spur nearly similar, but the band is not so much in 

 relief and is punctured instead of being smooth ; the male is very 

 narrow, the elytra being almost parallel from the humeral slope to 

 a short distance from the apex ; the punctures are equally rough at 

 base and apex ; the suture is carinate and ends at the apex in two 

 long, parallel spines ; the supra-marginal yellowish-white band is 

 proportionately as broad as in the female, but the inward spur is
