keel on the base of the metathorax as the male, but the 

 mesothorax is more coarsely punctured, and they are of 

 course larger and more robust. There is no supraclypeal 

 mark. I should have referred both sexes of 1047 to rotundi- 

 ceps, had I not seen both sexes of rotundiceps, with a quite 

 different male, from New South Wales. The type locality 

 of rotundiceps is Melbourne, and it was to be expected that 

 the Mackay insect would differ. The Mackay females were 

 not taken with the male, and may not belong to it ; their 

 status must for the present remain somewhat doubtful. 



Prosopi's chrysognatha, Ckll. 



?. — Sydney, New South Wales, Nov. 1905 {Turner). 

 British Museum. 



This agrees with Smith's description of P. simillima, 

 except that the first r. n. practically meets the first t.-c. The 

 male of chrysognatha is readily separated from simillima. 



Prosopis cyaneom icans, sp. n. 



? . — Length about 6 mm. 



Slender, head and thorax black, abdomen brilliant shining 

 blue; head ordinary, but wholly without pale markings; 

 clypeus striatulate and punctured; front shining, well punc- 

 tured ; flagellum light ferruginous beneath, dusky ferruginous 

 above ; mesothorax and scutellum shining, with strong well- 

 separated punctures; metathorax large and prominent, the 

 basal area transversely striate ; tubercles with a white spot, 

 but thorax with no other light markings ; tegulaj shining 

 piceous. Wings clear ; nervures and stigma dark reddish 

 brown, first r. n. meeting first t.-c. Legs black, hind tibite 

 white at extreme base. Abdomen little sculptured, the basal 

 segment especially smooth and shining, apical part with 

 black hair. In the table this runs to 12, and falls nearest to 

 P. cyanophUa, differing greatly by the shining and brilliantly 

 coloured abdomen. It is not unlikely that when the male is 

 discovered it will be seen to be a Meroglossa.

Prosopis cenibera, sp. n. (lateralis, subsp. ?). 



? . — Appearance of P. lateralis, Smith, for which I had 

 taken it, but it differs in the form of the metathorax, the area 

 being well defined and boat-shaped, its surface dull with a
