the former; remainder of body smooth and shining, with 

 small, scattered piligerous punctures. 



Hairs as in longiceps and pythia, except that they are 

 very long on the gula, forming a well-developed psammo- 

 phore ; on the scapes and legs they are more oblique than in 

 longiceps and more as in pythia. 



Colour variable, and like that of longiceps. 



Female. — Length, 13 mm.; wings, 13"5 mm. 



Similar to the females of the two preceding species. 

 Head subrectangular, a little broader behind than in front, 

 with rounded posterior corners. Antennal scapes extending 

 only a short distance beyond the posterior border of the head. 

 Thorax rather long; base of epinotum long, its spines acute, 

 shorter than in longiceps and directed downward and back- 

 ward. Scutellum and petiolar node without median impres- 

 sion. Venation of the wings as in the preceding species. 



Smooth and shining; mandibles subopaque, finely striate ; 

 ctypeus transversely rugulose; head finely, longitudinally 

 rugose; rugosity on the base of the epinotum above fine, 

 indistinct and transverse, more distinct and longitudinal on 

 the sides. 



Hairs similar to those of the worker but rather short, 

 except on the gula, where they form a psammophore, as in 

 the worker. 



Colour uniformly yellowish-ferruginous, with slightly 

 paler legs. Wings yellowish-hyaline, as pale as in pythia, 

 with dark-brown radial vein and aj:>terostigma ; remaining 

 veins resin-coloured. 



Hah.- — South Australia: Adelaide (type locality) (A. M. 

 Lea and Rothney) ; Meningie (L. H. Mincham) ; Gawler (A. 

 M. Lea) ; Karoonda to Peebinga (G. E. H. Wright). Western 

 Australia: Dongarra ; Gooseberry Hill; Wallaby Island: 

 Beverley (F. H. Duboulay). Victoria: Sea Lake (J. C. 

 Goudie). New South Wales: Yanco (W. W. Froggatt). 



This species, described from numerous workers from 

 many of the localities cited above and a single female taken 

 by Mr. G. E. H. Wright between Karoonda and Peebinga, 

 is readily distinguished from longiceps and pythia by the 

 conspicuous psammophore of the worker and female, by the 

 peculiar shape of the head and very short epinotal spines of 

 the worker, and by the downwardly-directed epinotal spines 

 of the female. The male seems to have been seen by Forel, 

 but was not described, as it was referred to longiceps. When 

 again taken it will probably be found to differ as much from 

 the males of longiceps and pythia as the worker and female 

 differ from the corresponding phases of these species.
