with only feeble indefinite punctuation. Pronotum as long as 

 the mesonotum and with microscopic coriaceous sculpture; the 

 niesonotum and scutellum smooth, shining, impunctate or nearly 

 so; propodeum, seen from in front, reticulately rugose and 

 bounded by the usual raised line; posteriorly dull, very finely, 

 microscopically granulate, and with the median area perceptibly 

 marked out, but only feebly defined. Abdomen smooth, shining. 

 \Vings with pale nervures, stigma and radius brown or fuscous. 

 Length hardly 2 mm. 



Bab. Bundaberg, Queensland; bred. 



PROSANTEON, gen. nov. 



Head in front with coarse shallow puncturation, the vertex 

 convex, the antennae with the joints becoming wider towards 

 the apex of the flagellum, the widest hardly longer than wide; 

 scape fully as long as the two following joints together. Mandi- 

 bles quadridentate. Maxillary palpi six-jointed, labial three- 

 jointed. Pronotum very short in dorsal aspect, being strongly 

 deflected from behind forwards; mesonotum with the parapsidaf 

 furrows very widely separated and failing about the middle; pro- 

 podeum with very well marked posterior median area. Front 

 tarsi quite different from those of any of the preceding genera, 

 rnd resembling Paranteon; fourth joint vei^y small and short, 

 not differing greatly from the third, fifth a nearly normal claw- 

 joint, but with a very short, free, basal production beneath, which 

 underlies the short fourth joint. 



Prosanteon chelogynoides, sp. nov. 



Black, the mandibles for the most part, the scape of the anten- 

 nae, and all the legs nearly wholly, pale, yellow or testaceous, 

 second joint of the antennae obscurely pale, the third very slight- 

 ly so; posterior coxae black. 



Head somewhat shining and with very shallow, coarse, close 

 punctures, so that it appears feebly reticulately rugose; fifth joint 

 of antennae a little wider than the fourth, the widening of the 

 joints of the flagellum being very gradual. Mesonotum very 

 smooth, shining, finely and sparsely punctured, propodeum with 

 its dorsal surface at least as long as the scutellum, reticulately 

 rugose and bounded by the usual raised line; its posterior face 

 v.-ith the median area somewhat shining and very distinctly mark- 

 ed by raised lines, outside which it is dull and densely and finely
