150 MEMOIRS OF THE QUEENSLAND MUSEUM. 
Face between the cephalic ocellus and the great facial impression nearly smooth but with some 
sparse and very faint punctures. Mesonotum finely punctured and somewhat shining, the 
scutelium excessively densely sculptured except at apex, the axilla’ meeting inwardly. Wings. 
with a very short marginal fringe, the marginal vein very short (twice longer than wide) ,* the 
stigmal longish and clavate (subequal to the marginal), the postmarginal indistinct and little 
developed; the oblique, hairless line present. Abdomen short, triangular, about as long as the 
thorax, concave above, the ovipositor very slightly extruded, the hypopygium not prominent. 
With the habitus of Parencyrtus Ashmead. Antenne 11-jointed, the club 3-jointed. 
Male differing in the comparatively small, widely separated eyes, the ocelli in a sub- 
equilateral triangle, the very dense surface sculpture of the head and mesonotum and the more 
hairy antenne with a solid and smaller club-joint (the antenne 9-jointed). 
1. ECHTHRODRYINUS DESTRUCTOR Perkins. Female; male. Genotype. 
Length, 1 mm. 
Head black, the mesonotum blue, metallic, in some aspects shining, very finely punctured 
and clothed with short black hairs; scutellum dull at base and with very dense, microscopic 
sculpture, its apex in some aspects shining and brilliantly green or blue and with some longish 
dark hairs; thorax beneath and the pleura, black, not or hardly metallic; abdomen bright 
metallic green on the basal portion. Wings hyaline, uniformly hairy except at base, the venation 
obseure brownish yellow. Antenne sordid yellowish, clothed with short hairs. The whole of 
all the legs pale yellowish. 
Habitat: Queensland. Parasitic on larve of Neodryinus, Paradryinus and so forth. 
Type: Query. 
2. ECHTHRODRYINUS XANTHOGASTER new species. 
Female :—Length, 1.20 mm. With the habitus somewhat of Hadronotus. 
Dark metallic blue, the abdomen honey yellow and margined nearly to tip from base 
with brownish. Wings subhyaline, the venation as figured for the genotype; oblique hairless 
line present. Legs and antenna pale yellow, the scape concolorous at proximal half, the pedicel 
above at base. Funicle hispid, the joints all shorter than the pedicel, 1-3 narrower and shorter 
than the others, quadrate; 4 a little longer than wide, 5 and 6 subquadrate. Pedicel not long. 
Club naked, subequal in length to the three preceding joints combined. Scape slightly com- 
pressed. Mandibles as figured for the genotype. Axille connate at meson. Fore wings with 
short marginal fringes, slightly stained about the marginal and stigmai veins. Body finely 
densely scaly, the mesonotum with scattered pin-punctures. Pubescence sparse. Seulpture of 
the axille finer. A spiracle on margin of abdomen just proximad of middle and which bears 
a few very long hairs. Apparently agreeing in other characters with the genotype. Hind tibial 
spur single, small. Frons narrow. Club very little wider than funicle. 
Described from one female captured by sweeping in the jungle, July 24, 1913. 
Habitat: Gordonvale (Cairns), Queensland. 
Type: No. Hy 3101, Queensland Museum, Brisbane, the specimen on a tag; the head, 
a fore wing and the anterior legs on a slide. 
The species resembles Coccidoxenus tricolor Girault but the marginal and stigmal veins 
are longer and the color of the abdomen is different. 
GENUS LEPTOMASTIX Foerster. 
Synonym: Calocerinella Girault. 
In the Australian species the head is lenticular, the costal cell extraordinarily narrow 
so that the marginal vein appears to be very elongate. Frons broad. Wings long, rather 
slender. Cheeks short, the eyes long. Scape long, slender, the bulla long. Stigmal and post-
