BULLA IMMACULATA, TllUllb. 



Vet. Ale. Handl. xxxi, 1875, p. 256, pi. 7, fig. 1. 



$ . Uniform pale green with the edge of the pronotal crest slightly 

 flavesceut or entirely pink (body, wings and legs). Closely resembling 

 B. unicolor but the crest of the hind lobe is a little more retuse in 

 front ; the head, prostenmm and legs are also pubescent, but the 

 face and vertex are weakly punctate, the anterior lobe is much less 

 rugosely plicate and non-granulate, the posterior is finely aciculate 

 punctate, the crest is smooth and less denticulate in the anterior 

 lobe ; abdomen with or without the lateral series of ocellate patches. 



Length 42-44 mm. 



$ . Also closely allied to the same sex of B. unicolor ; the anterior 

 lobe of the pronotum is slightly less rugose, and the posterior is less 

 closely and roughly punctate and there are no scattered tubercles ; the 

 body is green, the concolorous abdomen has a somewhat indistinct, 

 lateral white patch ; in the pronotum the white border of the lateral 

 sinuation is as in B. unicolor. 



Length 40-41 mm. 



Longer than B. unicolor. This species occurs in the Cape 

 Peninsula and in the neighbouring districts of Stellenbosch and the 

 Paarl. 



BULLA DISCOLOR, Tliunb. 

 cJ Vet, Akad. Handl. xxxvi, 1810, p. 57, pi. 2, fig. 2. 



cJ pupillata, Thuub., loc. cit. p. 60, pi. 2, fig. 4. 



$ . Pale green turning occasionally to pink. Differs from B. 

 it n i color and immaculata by the more elongate body, the glabrous head, 

 and the longer pronotum which, as much tectiform as in the other two 

 species, has the carina of the anterior lobe divided by four incisions 

 continued laterally as grooves ; the antennae ai - e of about the same 

 length, the face is closely coriaceous with a few granules, the sides of 

 the anterior lobe of the pronotum bear numerous granules, and those 

 of the posterior are roughlv coriaceous ; the impressions on the femora 

 are evident ; the abdominal segments have faint traces of two super- 

 posed ocellate spots ; the pectus is very slightly pubescent. 

 Length 4'J-44 mm. 



? . Green with the antennae, legs and crest and humeral ridge of 

 pronotum pinkish red in fresh examples. Face, genae, and especially 

 the labrum closely granular, vertex non-granulate ; pronotum tectiform, 

 the disk well defined by a raised ridge reaching from the anterior part 

 to two-fifths of the whole length ; anterior lobe with four incisions
