AUSTRALIAN HTMENOPTERA CHALC1D0IDEA, IV.—GIFAULT. 217 



Genus TETRASTICHUS Haliday. 



Several of the species have been removed to Neomphaloidella and Epitetrastichus 

 ■which see. 



1. TETRASTICHUS QUEENSLANDENSIS Girault. 



There is no lateral carina on propodeum, the latter short at meson. A row of punctures 

 along lateral margin of scutum. Type re-examined. 



2. TETRASTICHUS ACUTIVENTRIS (Girault). 

 Asyntomospliyrum acutiventris in antea. 

 Very similar to poincarei but the abdomen distinctly less stylate, the valves of the 

 ovipositor extruded for a third of the length of that region. Also, the funicle joints are all 

 globular and subequal, slightly longer than wide, subequal to the pedicel. Club with a short 

 terminal spine, the third joint not distinctly separated. Antennae pallid. Mandibles tridentate. 

 A female at Gordonvale. Types re-examined. 



3. TETRASTICHUS SAINTPIERREI Girault. 

 " One female, forest, Magnetic Island (Townsville), Queensland, January 27, 1913 

 (A.A.G.). The specimen agreed with the description of the species but funicle 1 was not 

 longer than 2. Compared with type (except antenna of latter). Propodeum extremely short 

 at meson. In this second female the antennae are yellow-brown, the funicle joints subequal, 

 each about a half longer than wide, the club almost as long as the two preceding joints united." 

 (A. P. Dodd). 



4. TETRASTICHUS UNICOLOR new species of Girault and A. P. Dodd. 



Female: — Length, 1.65 mm. 



Bright metallic green ; tibia3 and tarsi pale straw yellow ; femora suffused with metallic ; 

 antennae black, the scape brown. Wings hyaline. Abdomen conic-ovate, a little longer than 

 the head and thorax united. Funicle joints about subequal, each no longer than the pedicel 

 and not twice as long as wide. Propodeum short; spiracle small, circular; lateral carinae 

 absent: median carina broad, flat and short. 



Described from one female caught by sweeping in forest, June 25, 1912 (A. A. Girault). 



Habitat: Xorth Queensland (Gordonvale, near Cairns). 



Type: No. FLy2546, Queensland Museum, Brisbane, the above specimen on a tag, an 

 antenna on a slide. 



5. TETRASTICHUS LONGIPENNIS new species of A. P. Dodd. 



Female: — Length, 1.15 mm. 



Yellow-brown, the sides of thorax, parapsidal furrows and postscutellum a little darker,

 third funicle joint; funicle joints very long, 1 distinctly the longest; club not much shorter 

 than the funicle, the club joints of equal length; ring-joints not small.
