Synopsis of Species. 



Elytra with the intervals equal, and three series of brassy shining 

 spots on each side rugosimi. 



The brassy spots on the dorsal series close to one another . . . . hottentotiim.

 brassy spots on each side scnccjalense. 



Elytra with the alternate intervals much raised and without any 

 brassy punctures pla^iicolle. 



Calosoma kugosum, De Geer, 

 Mem. Hist. Ins., vii., p. 627, pi. 47, fig. 2. 

 C. chlorosticum, Klug, Symb. Phys., iii., pi. 23, fig. 10. 



Greenish bronze, more or less shining on the upper part, shining ; 

 palpi piceous ; antennae with the four basal joints piceous, the 

 others rufescent ; head closely but not deeply punctured ; prothorax 

 one-third broader than long, with the outer sides rounded and 

 carinate, and the median part inflated, finely shagreened, de- 

 pressed on each side near the base, and with a short median 

 longitudinal very narrow groove ; scutellum smooth, triangular ; 

 elytra twice as broad at the base as the hind part of the prothorax, 

 gradually ampliate from the shoulder to three-fourths of the length, 

 but with the outer sides linear, diagonally rounded behind, not 

 very convex ; narrowly punctato-striate, with the intervals convex 

 and regularly and deeply creased transversely, and with three regular 

 series of equidistant shining brassy round dots on each side ; legs 

 and under side piceous. Length 18-26 mm. ; width 9-1 1-J- mm. 



Varies much in size, is generally smaller in such localities where 

 droughts are of common occurrence, such as the north-western part 

 of the Cape Colony. I own a male example from the neighbourhood 

 of Kimberley only 15 mm. long and 7 mm. in width.

Calosoma hottentotum, Chaud., 

 Bull. Mosc, 1852, i., p. 99. 



Size, shape, and colouring of C. rugosum. 



The description given by De Chaudoir is most obscure, but having 

 been enabled to examine the type, I find that, according to my notes, 

 the only difference between rugosum and hottentotum is that the 

 brassy spots on the elytra are much more closely set in the second 

 than in the first-named species. Chaudoir says that that species 

 was labelled in Dupont's collection as coming from the Cape of Good 

 Hope. I have good reason to believe that Dupont's collection 

 included Delegorgue's captures, was made not in the present colony 

 of the Cape of Good Hope, but in what is now the Transvaal,
