A. A. Girault: 



as in species of Tetrastichus but the scutum densely scaly except 

 at cephalic third. Venation yellow. Sides of abdomen margined 

 with brown. Antennae 10-jointed, one ring-joint and a 3-jointed 

 club, the third joint of the latter very minute like a nipple yet 

 apparently articulated. Funicle joints subequal, each slightly 

 longer than the pedicel. Propodeum with a long median carina, 

 nearly smooth. 



Male: Unknown. 



Described from one female captured by sweeping in the forest, 

 April 15, 1912. 



Habitat: Australia — Nelson (Cairns), Queensland. 



Type: In the Queensland Museum, Brisbane, the above 

 specimen on a tag, the head on a slide. 



The axillae in this genus are not advanced and the habitus 

 resembles that of certain miscogasterids, the distinctly petiolated 

 abdomen adding to the effect. The submarginal vein is distinctly 

 broken. 



2. Euplectrus cairnsensis new species. 

 Female: Length, 2.15 mm. 



The same as the preceding but the head is black, the wings 

 perfectly clear and its details different, the spurs of the posterior 

 tibiae decidedly longer, the longest over half the lentgh of the 

 tarsus, not quite half the length in the preceding species; the first 

 and fourth joints of the funicle are a little longer than either of 

 the two middle joints. Differs from australiensis by the different 

 sculpture and the yellow posterior coxa. 



Male: About the same in coloration and sculpture. 



Described from one female captured by sweeping foliage and 

 grass in a bog, October 25, 1911. A Male was captured in a jungle 

 pocket at Nelson, May 11, 1913. 



Habitat: Australia — Cairns and Nelson, Queensland. 



Type: In the Queensland Museum, Brisbane, the above 

 specimens on a tag. 



3. Euplectrus melanocephalus new species. 

 Female: Length, 2.20 mm. 



Differing from the preceding in having the posterior coxa 

 black; like australiensis but the sides of the abdomen (from above) 

 margined with purplish black while the whole distal third of that 

 region is the same color; pronotum not punctate, only feebly alu- 

 taceous, the Vertex nearly smooth; sculpture otherwise as in 

 xanthocephalus; antennae blackish toward tip. 



Male: Not known. 



From one female captured by sweeping in the pocket of jungle, 

 8 May, 1913 (A. P. Dodd). 



Habitat: Australia — Nelson (Cairns), North Queensland. 



Type: In the Queensland Museum, Brisbane, the above 

 specimen on a tag.
