250 WHEELER. 



on the sides. Petiole from above subrectangular, a little longer than 

 broad, as broad in front as behind, with straight anterior and posterior 

 borders and evenly rounded sides; in profile the dorsal surface is 

 strongly convex, the anterior and posterior surfaces short and slightly 

 concave, the former strongly marginate above and on the sides, the 

 ventral surface with a small, sharp tooth at the anterior end. Post- 

 petiole decidedly broader than the petiole, as long as broad, broader 

 behind than in front, with convex sides and dorsum, with a small 

 acute tooth at its anterior border on the ventral side. Gaster rather 

 slender. Pygidium evenly and broadly rounded at the tip. Cerci 

 absent. Genital appendages blunt, retracted. Hypopygium with 

 broad posterior border, feebly and narrowly emarginate in the middle. 

 Legs slender, hind coxge without lamellate tips. Wings short, with 

 large, thick pterostigma. There is a well-developed discal cell 

 but the veins distal to it are so nearly obsolete that those outlining a 

 closed marginal and single cubital cell are scarcely visible as very 

 delicate folds in the wing membrane. 



Mandibles and space between the frontal carinje shining; mandibles 

 coarsely and sparsely punctate; remainder of head opaque, finely 

 and densely punctate, with very uneven surface. Sides of pronotum, 

 the mesonotum and mesopleurpe smooth and shining, the mesonotum 

 with scattered, piligerous foveolte; middle of pronotum, the whole 

 epinotum, petiole and postpetiole subopaque, finely punctate and 

 rugulose, the rugfe on the base and sides of the epinotum coarse, 

 somewhat longitudinal on the base near the margination separating 

 it from the declivity ; the latter finely and densely punctate. Gaster 

 shagreened, coarsely on the base of the first segment, finely elsewhere 

 so that the surface is shining. 



Hairs yellow, bristly, suberect, pointed, scattered, covering the body 

 and legs rather uniformly, present only on the anterior surfaces of 

 the scapes. Pubescence yellowish, distinct only on the scapes. 



Red; ©cellar region, middle portions of tibire and femora, middle of 

 pronotum and anterodorsal portions of petiole and first gastric seg- 

 ment brown. Wings whitish hyaline, with yellow veins and very 

 conspicuous dark brown pterostigma. 



Described from a single specimen from Murat Bay, South Australia 

 (Museum of South Australia). There is another defective specimen 

 in the same collection from Ardrossan, South Australia (J. G. O. 

 Tepper) . 



This may be the male of one of the smaller red species of Phyracaces 

 described in the preceding pages.
