AUSTRALIAN HTMENOPTEEA CHALCIDOIDEA, IV.—GIBAULT. 223 



imicarinate (median), the caudal margin strongly carinate and a neck indicated, from each 

 lateral end of which is a short piece of a lateral carina, thus this carina indicated from apex 

 (caudad). Stigmal vein long. Allied with tenuis. Scape slender. 



' ' First three tarsal joints very short, the fourth much enlarged, as long as the others, 

 with a large swollen empodium, the claws large." (A. P. Dodd.) 



From one female captured by sweeping in jungle, May 5, 1914. 



Habitat: Gordonvale (Cairns), Queensland. 



Type: No. Hy2556, Queensland Museum, Brisbane, the specimen on a tag; head and 

 legs on a slide. 



Another female was taken, January 29, 1911 in same place (A. P. Dodd). 



8. APROSTOCETUS PURPURE1VARIUS new species. 



Female: — Length, 1 mm. 



Similar to riridiflavus Girault but not only the pedicel at base and the distal club joint 

 is purple black but the entire club is so and each funicle joint is distinctly blotched with purple 

 at proximal half. Moreover, the terminal spine of club is longer and funicle 2 is distinctly 

 the longest ; funicle 1 subequal to the pedicel and somewhat shorter than 3. Propodeum with 

 a weak median carina and no others. 



One female captured by sweeping in jungle, March 6, 1914 (A. P. Dodd). 



Habitat: Cooktown, Queensland. 



Type: No. Hy2557, Queensland Museum, Brisbane, the female on a tag, head on a slide. 



9. APROSTOCETUS TENUIS new species. 



Female: — Length, 0.90 mm. 



Colored somewhat like margivcniris Girault but the legs and antenna? wholly pale lemon 

 yellow, the coxa? blackish at base, the body is shining black, the distal sixth (tip) of abdomen 

 and margins all around narrowly, black, the cross-stripes of black commencing just within the 

 proximal half and three in number, not especially thin. The funicle is the same but either 

 of the distal two joints is longer than the pedicel. Mandibles tridentate. Distal club joint 

 dusky. Propodeum tricarinate, the median short but complete. 



Described from female captured by sweeping in a jungle pocket, June 3, 1913 

 (A. P. Dodd). 



Habitat: Gordonvale (Cairns), Queensland. 



Type: No. Hy2558, Queensland Museum, Brisbane, the above specimen on a tag, the 

 head on a slide. 



10. APROSTOCETUS FLAVOBASALIS new species.

Coloured much like impcrialis but dark asneous green, the venter of abdomen yellow only 

 proximad and the yellow spot above near (not just at) base is of moderate size only; also

 the first short, obtusely pointed, the second broadly truncate) ; the distal funicle joint is longer, 

 the pedicel somewhat shorter; funicle and club darker, blackish, the distal club joint whitish. 

 Propodeum with a long, distinct median carina. Scape, pedicel and ring-joint lemon yellow 

 like the legs. Sculpture of propodeum rougher than rest of thorax, the lateral carina? not very 

 distinct.
