submarginal vein. In this second species there is a silvery crescent on thoracic pleurum just 
cephalad of the mesopleurum, the latter very finely polygonally reticulated. 
From one female caught September 28, 1913 (H. Hacker). 
Habitat: Caloundra (Brisbane), Queensland. 
Type: No. Hy 2983, Queensland Museum, Brisbane, the specimen on a tag; head and fore 
wing on a slide. 
3. CERCHYSIUS ROBUSTUS new species. 
Female :—Length, 2.50 mm., excluding ovipositor which is extruded for a length equal to. 
two thirds that of the abdomen. 
Differs from the genotype of Coccidoxenus in that the frons is moderate, not prominent, 
the scrobes deep, forming a semicircle or nearly; the postmarginal vein is somewhat shorter than 
the stigmal and the axille are a little separated. 
Metallic blue-green, the abdomen except across the base, very deep blue nearly black. 
Valves of ovipositor and antenne black; knees, tips of tibizee (more broadly in intermediate 
legs being nearly distal half) and the tarsi reddish yellow. Head and thorax very finely scaly 
and with many scattered, small setigerous punctures; scaliness of scutellum distad with a 
longitudinal direction or flow. Wings hyaline, the venation dark. Postmarginal vein only 
about half the length of the stigmal, somewhat longer than the marginal. Mandibles with 
the two outer acute teeth longer than the inner. Oblique hairless line of fore wing with about 
four short lines of discal cilia proximad of it. Hind tibial spurs double. Head with short, 
stiff white hairs scattered over the surface and which contrast. Pedicel subequal to funicle 2, 
funicle 1 longest, somewhat over twice longer than wide; other funicle joints each shortening 
a little, 6 being subquadrate; club short, not more than somewhat over a third the length of 
the funicle. Funicle densely clothed. Valves of ovipositor a little compressed. Scutum a 
little longer than scutellum. Propodeum and abdomen scaly, the former with an intermediate 
glabrous portion on each side of meson. Pubescence of scutum similar to that of the head but 
not as conspicuous. 
From one female caught in forest, November 5, 1913. 
Habitat: Gordonvale (Cairns), Queensland. 
Type: No. Hy 2984, Queensland Museum, Brisbane, the female on a tag; head, fore 
wing and hind tibie on a slide. 
4. CERCHYSIUS BELLULUS new species. 
Female :—Length, 1.65 mm. Ovipositor extruded a very short distance. 
Dark metallic purple, the wings uniformly lightly stained and with a small darker stain 
along the stigmal vein. Legs concolorous but the tarsi and tips of tibie pale. Stigmal and 
postmarginal veins subequal, the latter a little longer; hind tibie with one spur. Antenna 
12-jointed, the ring-joint exceedingly short, hidden, the whole blackish; club 3-jointed. Eyes 
convergent above. Thorax very finely shagreened and the scutum and scutellum with numerous 
setigerous thimble punctures which are conspicuous but not confluent by far. Axille barely 
separated. Abdomen scaly. Pedicel longer than all the funicle joints (separately) of which 
1-3 are subequal each slightly longer than wide. Frons rather narrow. Cheeks somewhat shorter 
than the eyes. Mandibles usual. Venation fuscous. :

5. CERCHYSIUS AUSTRALIS new species. 
Female :—Length, 2.10 mm., excluding the ovipositor which is three fourths the length 
of the abdomen; their valves compressed a little, a little broader than usual. 
Dark metallic green, the abdomen blackish, the legs black; valves of the ovipositor black. 
Fore wings with a distinct brownish band across them from the marginal and stigmal veins,
