POLYGYSTOMYIA new genus of 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. Antennas 13-jointed with three 

 ring and three club joints. Parapsidal furrows one third complete. Scutellum simple. Pro- 

 podeum punctate, rather long, without carinas 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, 3-5 subequal, each barely half as long 

 ps 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 coxas and base of other coxas 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 funicle joint, which is 

 distinctly longer than wide, funicle 1 distinctly longer than the pedicel, the others gradually 

 shortening; club no wider than funicle, as long as two preceding joints united; first two 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. Ey28l2, Queensland Museum, Brisbane, the specimen on a tag, the head, 

 on a slide. 



PTEEOSEMELLA 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 MEEISMOMOEPHA Girault. 

 1. MERISMOMORPHA ACUTIVENTRIS Girault. 



The type measures 1.50 mm., is a female on a tag and was captured May 18, 1913. 



PTEEOSEMIGASTEA new genus of Girault and A. P. Dodd. 



Female: — Head no wider than the thorax. Antennas 13-jointed, with two ring and 

 three club joints. Pronotum not long; scutum with complete parapsidal furrows; scutellum 

 with a delicate cross-suture. Propodeum scaly, with a distinct median carina, also a cross- 

 earina, the lateral ends of which curve abruptly cephalad, joining the cephalic margin mesad 

 of the spiracles and thus forming short lateral carinas; spiracle small and rounded, without 

 distinct spiracular 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. 

 Ovipositor 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.
