Subfamily PONERIDES. 



1. Myrmecia vindex, F. Smith, var. desertorum, n. var. 



Worker. — Length, 15-17 mm. 



Resembling the var. nigriceps, Mayr., in colonration, but 

 with the red of the thorax and pedicel a shade more yellowish, 

 and more like the typical vindex in size and pilosity, the latter 

 being conspicuously more abundant than in nigrice/ps, especially 

 on the thoracic dorsum. The sculpture of the thorax is also 

 distinctly feebler and the surface more opaque than in this 

 variety and the typical form. 



Four workers from Todmorden. 



'2. Rhytidoponera cornuta, Emery, subsp. taurus, Forel. 

 A single worker from Moorilyanna, agreeing very closely 

 with a co-type in my collection. 



3. Rhytidoponera (Chalcoponera) metallica, F. Smith, var. 

 PURPURASCENS, u. var. 



Worker. — Length, 7 mm. 



Differing from the typical metallica from Eastern Aus- 

 tralia in colour, the head, thorax, petiole, and gaster being 

 deep metallic-violet, with the legs, mandibles, and a large 

 spot on the vertex purplish-brown, and the antennae black. 

 The sculpture is very much like that of the typical form, 

 except that the rugosity on the pronotum is somewhat more 

 irregular and the fine rugae are more nearly of the same 

 •character on the first and second gastric segments. 



A single worker from Moorilyanna. 



4. BOTHROPONERA PILIVENTRIS, F. Smith. 



A single worker, taken between the Musgrave Ranges 

 and Moorilyanna. 



5. Leptogenys (Lobopelta) conigera, Mayr., var. centralis, 



n. var. 



Worker. — Length, 6*o-7 mm. 



Differing from the typical form and the var. adlerzi, 

 Porel, of Queensland in the following characters : — The head
