220 MEMOIRS OF THE QUEENSLAND MUSEUM. 



5. TETRASTICHODES SECUS new species. 



Female: — Length, 1.20 mm. 



Nearly exactly like Syntomosphyrella acomala G-irault and Dodd but diffeiung in 

 coloration as follows: The whole of the propodeum is black and a little distad of middle of 

 abdomen there are two cross-stripes of black. The axillae are black for somewhat over cephalic 

 half. Funicle, pedicel and mandibles as in the species named. Tegula and vicinity black. 

 There may be a minute black dot on the shoulder and the scutum centrally may be more or 

 less dusky. There may be a third and fourth stripe on the abdomen, one proximad, the other 

 distad of the two lines and both interrupted at meson and a spot at base of scutellum. 



Male: — Not known. 



Described from four females reared from miscellaneous galls on Eucalyptus, October 9, 

 1913 (E. J. Girault). 



Habitat: Gordonvale (Cairns), Queensland. 



Type : No. Hy 3462, Queensland Museum, Brisbane, one female on a tag, the head on a 

 slide. 



6. TETRASTICHODES INTENTATUS new species of Girault and A. P. Dodd. 



Female: — Length, 1 mm. Short and robust, the abdomen stout. 



Brown ; the wings hyaline ; the abdomen with three broad black stripes across it, 

 equidistant from each end, each stripe distinctly interrupted at the meson; legs and antennae 

 yellowish. Funicle joints subequal, each a little longer than wide. Mandibles tridentate. 

 Head pale yellowish brown. Propodeum very short. 



Described from one female caught by sweeping in forest, mainland, opposite Double 

 Island, December 24, 1911 (A. A. Girault). 



Habitat: Northern Queensland (near Cairns). 



Type: No. Hy 2551, Queensland Museum, Brisbane, the above specimen on a tag. 



7. TETRASTICHODES AURIFLAVUS new species. 



Female: — Length, 1.80 mm. Form short and robust, the abdomen rounded. 



Bright greenish or golden yellow, immaculate, but sometimes a subfuscous spot is 

 present on pronotum, just cephalad of each parapsidal furrow and the abdomen has very 

 faint indications of deeper yellow cross-stripes. Mandibles tridentate. Pedicel not elongate, 

 but distinctly longer than first funicle joint which is somewhat longer than wide, distinctly 

 longer than joints 2 and 3 which are subequal and somewhat wider than long. Club without 

 a distinct terminal seta. Caudal margin of propodeum narrowly black. Scape somewhat 

 compressed. First tarsal joint of hind legs shortest. Ocelli in a very flat triangle. Propodeum 

 very short. 



Male: — The same but the abdomen depressed. 



Described from many specimens of each sex reared from miscellaneous galls on 

 Eucalyptus, forest, October, 1913. 



Habitat: Northern Queensland (Gordonvale, near Cairns). 



Types : No. Hy 2552, Queensland Museum, Brisbane, one male, two females on a tag. 



Ten females taken at random were examined for presence of the median sulcus on 

 the scutum and in most cases it was found present, though absent in five females examined 

 immediately after being taken from alcohol. However, in the ten dry females, the groove 

 was never complete, was often oblique, often accompanied by lateral and unsymmetrical cracks 

 and thus was most probably due to shrivelling. An examination for variation in the absence 

 of this groove will have to be made from specimens as they are taken from alcohol. In one 

 of these females, a dusky spot was present centrally at base of scutellum. There was no 

 variation in the antennae.
