THE CANADIAN ENTOMOLOGIST. 101 



ON SEVERAL NEW GENERA AND SPECIES OF 

 AUSTRALIAN HYMENOPTERA CHALCIDOIDEA. 



BY A. A. GIRAULT, BRISBANE, AUSTRALIA. 



The following genera and species were included within three 

 small collections of this super-family, loaned to me for study, but 

 do not include all of the material from them. Two of these col- 

 lections were from Queensland, the third partly from Victoria 

 and partly from New South Wales. 



Family Chalcididse. 

 Subfamily Chalcidinae. 

 Tribe Chalcidini. 

 Genus Tumidicoxa Girault. 



1. Tumidicoxa rufiventris new species. 



Female: Length, 5 mm. 



Opaque black, the abdomen rufous or orange red, as are also 

 the antennal flagellum, the posterior coxae, tibiae (except at tip) 

 and femora (except at apex, lateral), the cephalic tibiae, except 

 at base, and all the tarsi (somewhat diluted with yellowish) ; ce- 

 phalic and intermediate coxae black or very dark, the proximal 

 half or more of the cephalic and intermediate femora black, their 

 distal half or less honey yellow. Scape dark fuscous, the pedicel 

 somewhat lighter. Tegulae, a rounded spot at apex of posterior 

 femur laterad, a distinct oval spot near tip of posterior tibiae and 

 the knees more or less lemon yellow. Wings very slightly stained 

 throughout, the venation smoky. Pubescence not conspicuous, 

 with a reddish tinge. 



Scrobicular cavity nearly smooth, shining; head and thorax 

 rugoso-punctate, the propodeum mesad (dorsal aspect) foveate, 

 the abdomen glabrous, but the distal segments finely, polygonally 

 sculptured. Lateral ocelli distinctly more than their own dia- 

 meter from the eye margin. Plate at apex of scutellum distinctly 

 bilobed. Propodeum in the dorso-lateral aspect, with at least 

 one tooth-like projection, its lateral aspect moderately hairy, but 

 not conspicuously so. Posterior femora with one moderately 

 large tooth, followed by about ten others, which are smaller distad, 

 all the ten much smaller than the first. Antennae 12-jointed, 

 the single ring-joint large, the pedicel as long as the first funicle
