AUSTBALIAN HYMEN OFTEBA CHALCIVOIDEA, IV.—GIEAULT. 231 



2. TETRASTICHOMORPHA ^NEICORPUS new species of Girault and A. P. Dodd. 



Female: — Length, 1.65 mm. 



Dark aeneous green, the wings hyaline, the legs white except hind coxaa, the scape white' 

 except at tip; rest of antennae black. A small triangle of lemon yellow just in front of 

 cephalic ocellus. Propodeum with a distinct median carina and no others, the sculpture roughly 

 pclygonally scaly. Abdomen metallic blue. Median sulcus of scutum incomplete cephalad. 

 Abdomen sculptured like the thorax, conic-ovate, a little longer than the rest of the body. 

 Second ring-joint short, the pedicel long, a little shorter than the distal club joint which is 

 about one and three fourths times longer than broad; first funicle joint subequal to the club, a 

 fourth longer than the second, which is a little over twice longer than wide. Mandibles 

 tridentate, but the third tooth emarginate and oblique at apex. Marginal vein longer than 

 the submarginal, long, the stigmal short, with a short neck. 



Described from one female caught by sweeping in the bed of a forest streamlet, 

 December 4, 1913 (A. A. Girault). 



Habitat: Northern Queensland (Gordonvale, near Cairns). 



Type: No. Hy 3481, a female on a tag, the head on a slide. 



Genus SELITEICHODELLA Girault. 



1. SELITRICHODELLA MIRA Girault. 



The species measures about 1.15 mm. and is associated with a gall on the midrib of 

 leaves of cockatoo apple. Posterior wings acutely pointed. The type specimens were reared 

 December 15, 1912 and are together on a slide. 



A female at Cairns, Queensland, by sweeping in forest, October 25, 1911. The proximal 

 funicle joint is somewhat shorter than each of the other two. The scape is distinctly 

 compressed, more so than with meteora, described next. It is more robust than meteor a. 



2. SELITRICHODELLA METEORA new species. 



Female: — Length, 0.63 mm. 



Like mira but distad the abdomen bears one complete cross-stripe of purple between 

 the ends of the cut-off marginal stripe, a spot of purple dorsad centrally at tip and the 

 indications from each side of a second cross-stripe a little proximad of the first. Both 

 mandibles bidentate, the inner tooth broadly truncate, the mandibles weak. The two distal 

 funicle joints subequal, each a little longer than the first, a little shorter than the pedicel. 

 Coxae concolorous. 



Described from a single female captured from a window, September, 1913 (A. P. Dodd). 



Habitat: Gordonvale (Cairns), Queensland. 



Type : No. Hy 2577 , Queensland Museum, Brisbane, the specimen on a tag, the head on 

 a slide. 



3. SELITRICHODELLA PURPUREITHORAX new species. 



Female: — Length, 1.10 mm. 



Like meteora Girault but the abdomen more slender, longer than the rest of the body, 

 its tip distinctly rather broadly purple and the stripes on the abdomen are reversed and 

 more pronounced — thus at the termination of the marginal stripe on each side not far from 

 the purple of tip there is an indication from each side of a cross-stripe and a complete, 

 distinct cross-stripe farther proximad (farther proximad than the indicated cross-stripe in 

 meteora and farther from ends of the marginal stripes), at about somewhat more than distal
