1G2 Mr. T. D. A. Cockerell — Descriptions and 



not evidently punctured ; flagcllum reddish brown beneath ; 

 mesothorax very finely punctured ; tubercles, scutellum, 

 axillre, and postscutellum bright chrome-yellow ; area of 

 metathorax roughened basally ; legs black, anterior tibiae 

 reddish basally in front, and with a small cream-coloured 

 streak, hind tibiae with a subbasal cream-coloured spot. 

 Wings hyaline, scarcely dusky, recurrent nervures meeting 

 transverso-cubitals. Except for the faint bluish tint of 

 abdomen, this runs in the table to P. frederici*. According 

 to Smith, fredtrici has the abdomen (i obscurely tinged with 

 blue," but it is so faint that I overlooked it when examining 

 the type. P. fredtrici is, however, larger, and has the 

 abdomen "covered with a changeable white pile, observable 

 in certain lights." Bun among the metallic species, P. bi- 

 cuneata goes to 19, and runs out because of the very line 

 sculpture, combined with cuneate face-marks. 



Ilab. Mackay, Queensland, March 1900 {Turner). 



Superficially the insect is like P. xanthaspis. 



Prosopis rollei, Ckll. 



In the Turner collection are two females and three mal.s 

 from Victoria [C. F.). The females are P. elegans, Sm., 

 agreeing with ia specimen from Adelaide, the type locality, 

 though the abdomen is much more clouded with black than 

 Smith describes. The males are P. rollei, Ckll., described 

 from Ararat, Victoria. Smith describes the male of P. elegans 

 as having the postscutellum black, and the abdomen " having 

 only the two basal segments and a line down their centre 

 black" ; but this statement about the abdomen is erroneous, 

 and was evidently meant to read " only the two basal seg- 

 ments red, a line" &c. P. sydneyana, Ckll., which I 

 determined as elegans by comparison of types, represents a 

 variety with the postscutellum yellow. 



P. rolJei is readily separable from elegans in the male, but 

 it may be that females at present ascribed to elegans belong- 

 in part to rollei. 



Prosoins coronata, Ckll. 



This was described from the male. Turner's 871 (Mackay, 

 Nov. 1893) appears to be its female. It is about G turn, long, 

 more robust than the male, but with the same finely punc- 

 tured mesothorax, red abdomen, &c. The clypeus, labrum, 

 and mandibles are red, and there are narrow, almost linear,
