Austrostigmus duhius, sp. n. 



$. Nigra; mandibulis, antcmiis, tcgulis pedibusqiio bruaoo- 



testaccis ; alls hyaliuis, venis testaceis j inesonoto rugoso. 

 Long. 4 mm. 



? . Head longer than broad, with a carina from tlie 

 anterior ocellus to the base o£ the clypcus, the carinre round 

 the eyes stronj^ly developed, the front between the carinse 

 punctured-rugulose. Eyes divergent toward tiie clypeus; 

 posterior ocelli as near to the eyes as to each other. 

 Antennas inserted on each side of the clypeus, nearer to the 

 base than to the apex, farther from each other than from the 

 eyes, as long as the head, the flagellum more than twice as 

 long as the scape. Pronotum transverse, pointed at tiie 

 angles; mesonotum rugulose ; scutellum smooth, opaque; 

 niesopleurse opaque, with a few scattered punctures. En- 

 closed area o£ the median segment well detined, almost 

 triangular, the marginal carinre not quite meeting at the 

 apex, witli two longitudinal carinse near the middle, the 

 space between the carinte transversely striated ; the surface 

 of the posterior truncation indistinctly transversely striated, 

 with a fovea at the base. Abdomen smooth and shining, the 

 sixth segment without a ))ygidial area. Second cubital cell 

 very small, the second abscissa of the radius less than half 

 as long as the first, second cubital cell less than half as long 

 on the radius as on the cubitus, the length on the cubitus 

 equal to about half the length of the first transverse cubital 

 nervure; the recurrent nervare received at a distance before 

 the apex of the first cubital cell slightly exceeding the length 

 of the cubital margin of the second cubital cell.

This is very near A. queenslandensis. Turn., but differs in 

 the much coarser sculpture of the mesonotum, being inter- 

 mediate in this respect between queen slandensis and redculatus. 

 The second cubital cell in queenslandensis is triangular. 



Austrostigmus approximatus, sp. n. 



$ . Nigra ; anteunis, tegulia pedibusque bruueo-testaceis ; mandi- 

 bulis basi flavis, apice ferrugineis ; alis pallide flavo-hyaliuis, 

 venis pallide testaceis. 



Long. 4 mm. 



? . Head longer than the greatest breadth, finely shag- 

 reened, with a carina reaching from the anterior ocellus to 

 the base of the clypeus, and continued to the apex of the 

 clypeus in a gradually broadening form. Mandibles acutely
