the abdomen differenl not rich purple, but a sort of dark 

 indigo. The scutellum is yellow, with no black central 

 vitta, but bisected longitudinally by a sharply defined 

 sulcation buyssoni, Konow ( ?)* 



Victoria. 



(For localities of spp., so far as I know them, see the 

 Table of ?$ above.) 



1. Third cubital nerve bent as in PL XV, Fig. 14 ... . 2. 



— Third cubital nerve approximately straight 15. 



2. Hind tibiae considerably longer than hind tarsi (claw-joint 



included) 3. 



- Hind tibiae about as long as hind tarsi 14. 



3. Antennae of normal length, capitate, 3rd and following joints 



before the club distinctly separated, and never broader than 

 long 4. 



— Antennae paradoxically short, more or less clavate from the 



3rd joint onwards, the joints usually indistinctly separated 

 and broader (at their apices) than long 12. 



4. Intermediate segments of abdomen above clothed with dense 



rows of pale decumbent hairs, the hairs in each row of equal 

 length and lying parallel to one another (longitudinally). 

 (A character not unlike this occurs in o o of the non-Australian 

 genus Abia !) Large forms (about 20 mm. long in average 

 specimens) 5. 



- Intermediate segments of abdomen above glabrous ...(>. 



5. Head above and mesonotum (except its yellow scutellum) 



unicolorous (metallic greenish). (Abdomen usually coloured 

 similarly, but one specimen in B.M. from Melbourne has 

 it entirely i eddish !) Mesopleura with or without yellow 

 markings, but never perhaps entirely yellow (Type in B.M.). 



dorsalis, Leach. 



- Head and mesonotum coloured as in dorsalis, but mesopleura 



entirely yellow, and abdomen with its sides and apex rather 

 brightly rufescent. (Whether the unique B.M. 'Type'* 

 from Tasmania really belongs to its supposed $ and differs 

 specifically from dorsalis seems very doubtful) 



affinis, W. P. Kirby. 



* 1 have not seen the Type of buyssoni, which is presumably at 

 Berlin : but a single unnamed specimen in B.M. answers fairly 

 will to his description. The locality cited for it by Konow is 

 Tasmania.
