narrow clypeus and the eye, and are squarely truncate at level of antennse, except 

 that there is a short projection on the outer side, along the orbit ; clypeus with shallow 

 punctures : niesothorax densely punctured, but shining on disc ; mesopleura rather 

 sparsely punctured ; orange area on scutellum broadly triangular, the corners obtuse ; 

 postscutellum orange except at extreme sides ; tegulse black ; wings greyish hyaUne ; 

 b.n. meeting t.m. ; second s.m. receiving the recurrent nervures very near base and 

 apex ;. legs black ; abdomen moderately shining, finely and regularly punctured, 

 the punctures rather sparse on first segment, denser on second, very close on third ; 

 black hair at sides of apex. Base of metathorax rugose. 



" Bright V." {H. W. Davey). Very close to P. simillima Sm., but the face-marks 

 differ, and the face is broad, while the scutellum is only partly yellow. 



Palaeorhiza viridiirons n. sp. 

 Female. About 9 mm. long or rather over, robust ; black, with the front, 

 mesothorax, metathorax, and mesopleura green and purple, the metallic colour only 

 conspicuous under a lens ; first abdominal segment bluish green, especially the 

 depressed shining hind margin ; head without light markings ; flagellum dusky ferru- 

 ginous beneath ; scutellum (but not axillae), postscutellum, tubercles, and a very 

 large patch behind them, all bright orange ; clypeus elongate, longitudinally striate, 

 and sparsely irregularly punctured ; a shining area on each side between antennae 

 and eyes ; front densely punctured ; ocelli in a triangle ; mesothorax densely and 

 distinctly punctured ; area of metathorax beautifully green and purple, without 

 evident sculpture ; tegulse black ; wings brownish, stigma ferruginous, nervures 

 fuscous ; b.n. nearly meeting t.m. ; second s.m. receiving both recurrent nervures, 

 the first a considerable distance from base, the second bent strongly backward ; 

 legs black ; abdomen shining, the first segment finely punctured, densely at sides, 

 the third very much more closely punctured than the second, the latter also with 

 a small dull punctureless area in basal middle ; venter with coarse punctures. Hind 

 spur simple. 



Brisbane, 25-5-16 {Hacker). Although I have only the female, I am confident 

 that this is a Palceorhiza. It runs in my key to P. j^arallela Ckll., from which it is 

 easily known by the general colouration and the dark face. 



The above new species, and others with yellow or orange on scutellum and 

 postscutellum, may be separtaed by the following table. I include Euri/glossa auranti- 

 fera Ckll., which was taken by Mr. Hacker at Brisbane, 8-10-18, as it superficially 

 resembles the others. The specimen of P. aureomaculata subnubilosa taken by Mr. 

 Hacker has the first recurrent nervure joining the apical corner of first submarginal 

 cell, but the venation in this species is variable. Mr. Meade- Waldo (in lift.) expressed 

 the opinion that Prosopis nubilosa Smith should be referred to Palceorhiza, with 

 subnubilosa as a subspecies. The rediscovery of Prosopis quadrata Smith, described 

 from " New Holland," is of interest. The specimen was taken by Mr. Hacker at 

 Oxley, Brisbane, 17-9-14, at Leptm. [Leptospermum ?] flowers. It has the minutely
