Australian Braconidae in the British Museum. 113 



O. Face shining, minutely punctured, with sparse and very deli- 

 cate pubescence; median segment rather coarsely rugose. First 



tergite nearly twice as long as the apical breadth; second tergite 

 as broad at the apex as long, the impressed transverse line distinct. 

 The male has the first tergite shorter, less than half as long again 

 as the apical breadth.

This differs from A. tricolor in the sculpture of the median 

 segment. The second cubital cell is very small, the petiole 

 long. The West Australian Microdus rufithorax closely 

 resembles this species, but has the parapsidal furrows 

 well developed and the head black. 



Agathiella minima, sp. n. 



$. Nigra; prothorace, mesothorace scutelloque rufis ; palpis pedi- 

 busque anticis intermediisque testaceis; segmentis abdominalibus 

 duobus basalibus albo-flavidis, dorsali primo macula magna basali 

 nigra; tibiis posticis macula parva, obscura, basali, albida; alis 

 subhyalinis, costa nigra, stigmate venisque pallide brunneis. 



Long. 3 mm.; terebrae long. 2 mm. 



§. Smooth and shining; the median segment finely punctured- 

 rugose. First tergite scarcely half as long again as the apical 

 breadth; second tergite as broad at the apex as long, the impressed 

 transverse line very distinct. Calcaria of hind tibiae pale testaceous. 

 Second cubital cell triangular, the petiole short. 



Hub. N. Queensland, Kuranda (Turner). July 1913. 



It is possible that Ashmead's genus Orgiloneura may be 

 founded on a species of this genus with somewhat reduced 

 neuration, but his description is too short for any con- 

 clusions to be drawn. 



Platyagathis, gen. no v. 



Nearly allied to Disophrys, with which it agrees in the 

 short broad face, in the distinct marginal carinae of the 

 frontal depression and in the very short terebra. It differs 

 from Disophrys in the very broad and somewhat flattened 

 abdomen, which is sessile, with the first tergite as broad 

 at the base, as long and somewhat broader at the apex; 

 the intermediate and hind-tarsal ungues are simple, the 

 ungues of the fore tarsi bifid. The median segment is
