1 EUSTOCHOMORPHA HAECKELI new species. Female. Genotype. 

 Length, 1.25 mm. excluding the ovipositor. Uniformly brownish black, the wings 

 hyaline, the legs, scape and pedicel yellowish, the coxa? and hind tibiae and femora more or 

 less eoncolorous; fnniele joints all distinctly shorter than the pedicel, the first two subequal, 



barely longer than wide, the third plainly longer than them but only slightly longer than any 

 of the following joints of the funicle; club short, wider than the filiform funicle, its distal 

 joint plainly longer than the other, somewhat longer than any of the funicle joints. 



Habitat: Gordonvale (Cairns), Queensland. Forest, December 31, 1912.

1. GONATOCERUS TOLSTOII Girault. Female. 



Length, 0.80 mm. 



Jet black and thus in the group of species including nox and lomonosoifi, with which 

 it is more closely allied. It differs from the latter in the inequality of the funicle joints, the 

 first four joints all short but unequal, 1 and 2 equal (1 sometimes longer), globular, small, 

 3 and 4 equal (4 a little larger) globular but about twice larger, 4 less than half the length of 5 

 which is longest; joint 6 distinctly shortest of the distal four funicle joints, while 7 and 8 are 

 subequal or nearly to 5. Pedicel as long as distal funicle joint. In lomonosoffi, joint 6 

 subequal to 5. Fore wings slightly broader in this species but otherwise the two cannot be 

 distinguished. 



Habitat: Gordonvale (Cairns), Queensland. Forest, 1,500 feet, May 29. 



Type: No. HyS449, Queensland Museum, Brisbane. On a slide. 



2. GONATOCERUS LOMONOSOFFI Girault. Female. 



Length, 0.70 mm. Small for the genus. 



Jet black and thus distinguished from all species of the genus in Australia excepting 

 vox from which it differs as follows: Smaller, fore wings distinctly not so slender but 

 rather of the broader type (yet not wide, only about fifteen lines of discal cilia), the first 

 three funicle joints short and subequal, fourth only a little longer than third, the latter uot 

 longer than second as in nox, 5 plainly twice the length of 3, not so in vox; discal ciliation of 

 fore wings absent under marginal vein and the body somewhat darker. Wings hyaline. 



Habitat: Kuranda, Queensland. Jungle, May 18. 



Type: No. Hy345%, Queensland Museum, Brisbane, the female on a slide. 



3. GONATOCERUS BICOLOR Girault. 

 Only the female is known. There is now no reason for thinking that a mesopigescutum 

 is present. 



4. GONATOCERUS AUSTRALIENSIS Perkins. Male, female. 

 ' ' Ooctonus Haliday. 

 " Male antennae with 13 joints, the scape flattened and short, the second joint very 

 .small and roundish, the following ones subequally elongate, flattened and wide, but not so 

 wide as long. Antenna? of female 11-jointed; scape very long, set on an elongate pedicel, so 

 as to appear obsoletely 2-jointed, and as long as the three following joints together; club as long 

 as the three preceding joints together. Posterior ocelli wide apart, perhaps placed close to the 

 eye margins, the collapse of the head in dried specimens making it impossible to ascertain this 

 point. S .Helium large and elongate, lunger than the mesonotum; the axilhe encroaching a little
