sides, a striated transverse groove at the base and a median 

 groove from the base to the apex. Abdomen shining, 

 petiolate ; the basal three-fifths of the first segment linear, 

 the apical two-fifths gradnally broadened and slightly swollen, 

 the whole basal segment about twice as long as the posterior 

 femur. Third abscissa of the radius nearly twice as long as 

 the second, but a little shorter than the first; the first 

 recurrent nervure received by the second cubital cell at 

 about one-seventh from the base ; the second received by 

 the third cubital cell close to the base, almost interstitial 

 with the second transverse cubital nervure. Cubitus of 

 the hind wing originating beyond the transverse median 

 nervure.

lielated to P. interstitialis, Cam., which occurs in the 

 same locality, but the colour is very different, and the 

 position of the recurrent nervures is also different. Neither 

 species is very nearly related to true Psenulus. 



AUSTROSTIGMUS, gcu. n. 



Somewhat intermediate between Stigmus and Harpacto- 

 philus ; from the former of which it difl^ers in having the 

 abdomen subsessile, not petiolate, in the smaller stigma, the 

 longer and narrower first cubital cell ; from the latter in the 

 slenderer build, in the distinct transverse, angulated pro- 

 notum, the longer front with distinct carinse along the inner 

 margins of the eyes, and the recurrent nervure which is 

 received considerably before the apex of the first cubital 

 cell.

Stiymus qiieenslamlensis, Turn. Proc. Zool. Soc. Lcndou, p. 457 (1908). 



Austrostigmus reticulatus, sp. n. 



J . T^iger ; antennie ochraceis ; mandibulis, scapo subtus pedi- 

 busque fiavis ; tegulis testaceis ; alls hyaliuis, iridesceutibus, 

 venis testaceis ; mesonoto reticulato. 



Long. 4 mm. 



^ . Eyes distinctly divergent towards the clypeus, se- 

 parated at the base of the autenuce by a distance equal to 

 about twice the length of the scape ; clypeus narrowly 

 produced in the middle and subemarginate on the apical 

 maririn, with a median carina from the base. Flagcllum
