2. Abispa Australis. B.M. 



Female. Length 1 inch. — This species closely resembles A. 

 splendida, but appears to be intermediate between that species 

 and .^. ephippium. From A. splendida it differs in having the 

 head entirely yellow ; the scutellura and post-scutellum yellow ; 

 the metathorax is ])roportionably longer, its lateral posterior 

 angles are acute, and on each side is a sharp serrated ridge ; the 

 basal segment of the abdomen has the sides less distinctly 

 rounded. From A. ephippium it is distinguished by the colour- 

 ing of the basal segment of the abdomen, which in this species 

 is black, with a broad yellow band on its apical margin which 

 widens at the sides ; the segment is also more campanulate than 

 in A. ephippium, which has the segment entirely yellow. 



Hab. Port Essington. 



This insect is regarded by Saussure as a variety of ^. splendida ;
