POLYGYSTOilYIA new genus o±‘ A. P. Dodd. 
Female: — In Girault’s table of genera (see Memoirs of Queensland Museum, vol. II) 
running close to Polycysteloides Girault and Eurydinotomorpha Girault but differing from 
both these genera in bearing a nonearinate propodeum. Antenna3 13-jointed with three 
ring and three elub joints. Parapsidal furrows one third complete. Scutollum simple. Pro- 
Ijodeum punctate^ rather long, without carinse or sulci. Abdominal petiole very short; abdomen 
conic-ovate, depressed above, gently convex beneath, no longer than the head and thorax united;, 
second segment occupying barely one fourth of surface, 3-o subequal, each barely half as long 
5‘S 2, 7 somewhat lengthened. Marginal vein somewhat longer than the postmarginal, the latter 
almost twice as long as the stigmal. Mandibles not seen. 
1. POLYCYSTOMYIA PUNCTATA new species of A. P. Dodd. Genotype. 
Female: — Length, 2.60 mm. 
Dark metallic green, the posterior coxa3 and base of other coxa3 concolorous, rest of legs 
and antennal scape and pedicel golden yellow; rest of antennae black. Thorax, including pro- 
podeum, densely punctate. Wings hyaline. Pedicel subequal to last fnnicle joint, which is 
distinctly longer than wide, fnnicle 1 distinctly longer than the pedicel, the others gradually 
shortening; elub no wider than fnnicle, as long as two preceding joints united; first tw^o club- 
joints subequal; ring-joints increasing in size, the first small. 
Described from one female caught by sweeping in jungle, December, 1913 (A. P. Dodd). 
Habitat: Gordonvale (Cairns), Queensland. 
Type: No. Ey28W, Queensland Mnseimi, Brisbane, the specimen on a tag, the head 
on a slide. 
PTEBOSEMELLA new genus. 
For diagnosis, see antea, p. 317. The genotype is a new species. It measures 1.85 mm. 
and its types are six males on a card, the head and hind legs on a slide. The tegulae are pallid.. 
Genus MERISMOMORPHA Girault. 
1. MERISMOMORPHA ACUTIVENTRIS Girault. 
The type measures 1.50 mm., is a female on a tag and was captured May 18, 1913. 
PTEROSEMIGASTRA new genus of Girault and A. P. Dodd. 
Female: — Head no wider than the thorax. Antennse 13-jointed, with two ring and 
throe club joints. Pronotum not long; scutum with complete parapsidal furrows; scutellum 
wdth a delicate cross-suture. Propodeura scaly, -with a distinct median Carina, also a cross- 
Carina, the lateral ends of which curve abruptly cephnhul, joining the cej)hf]]ic margin mesad 
of the spiracles and thus forming short lateral carina}; spiracle smnll and rounded, w’itliout 
distinct spiracnlar sulci. Petiole of abdomen short and stout. Abdomen conic-ovate, longer 
than the thorax, straight above, convex beneath; second segment occupying one third of the 
surface; third and fourth segments subequal, each one half shorter than the second; fifth half 
as long as the third; sixth and seventh subequal, each as long or slightly longer than the fourth. 
Ovi];)ositor exserted for a length equal to one third that of the abdomen. Marginal vein one 
third longer than the postmarginal, the latter twice as long as the stigmal. Mandibles 3 and 
4-dentate.
