AUSTEALIAN HYMENOPTEllA CHALCIDOIDEA.—GIEAULT. 22Q 



Genus TOMOCERA Howard. 

 Belongs to the Cleonymidte which see. 



EURYDINOTELLA AUSTRALIA new species. 



Female: — Length, 1.65 mm. 



Differs from the genotype in that segment 2 of the abdomen is somewhat 

 longer than 3, the two occupying half of the surface, the postniarginal vein is 

 distinctly longer than the stigmal and there is only an abbreviated (very short) 

 lateral carina on propodeum from base to the mesal side of the minute spiracle. 

 Also the club bears a " fourth" minute joint ending in a short terminal spine. 

 Pedicel concolorous with the rest of the flagellum, the tip of the scape also but 

 rest of scape yellowish brown. Proximal half of caudal eoxns above metallic 

 green. Postniarginal vein not as long as the marginal. A round fovea just mesad 

 of the short lateral carina at base of propodeum. Segment 4 of abdomen as 

 long as 5 and 6 combined, shorter than 3, Whole of thorax scaly punctate, the 

 abdominal petiole scaly. Otherwise agreeing with the description of prima. 

 Occiput immargined. 



Described from one female caught on a window, Brooklyn, N.S.W., Nov., 

 1914. 



Type: No. Hy3r)67, Queensland Museum, Brisbane, the specimen on a 

 tag; fore wing, hind tibia? and the head on a slide. 



Genus NEOPTROCERUS Girault. 



In antea, original description, line 1, for lioptrGcerus Ashmead read 

 Tropidogastra Ashmead. 



Genus PACHYNEURON, Walker. 



Female: — In Ashmead 's (1904) table the following species run to Pachy- 

 neuron Walker but segment 2 of the abdomen occupies only somewhat over a 

 fourth of the surface. The parapsidal furrows are two thirds complete from 

 cephalad. Both mandibles 4-dentate. Antennae 13-jointed with two ring-joints. 

 Petiole of abdomen somewhat longer than wide. Propodeum with a distinct 

 neck, without a median carina, the lateral Y-shaped, the tail of the Y caudad 

 and not reaching the apex of the neck, one branch going to the meson at base 

 (really a loop — the opposite sides joined across the meson), the other to a point 

 on cephalic margin a short distance mesad of the spiracle. Marginal vein slightly 

 widening distad, two and a half times longer than wide at apex, the stigmal and 

 postmarginal very narrow and elongate, the first subequal to the thickened 

 marginal, the postmarginal distinctly longer than the marginal. A delicate, 

 narrow spiracular sulcus. Maxillary palpus 4-jointed, the last joint longest. 

 Genal suture absent. Antennae inserted a little above ventral ends of the eyes, 

 below middle of face. Axillae nearly joined. Head wider than the thorax. 



PACHYNEURON EMERSONI new species. 

 Female: — Length, 1.35 mm. 



Very dark metallic green-black, the wings hyaline, the venation blackish, 

 the body scaly except the much less so propodeum and body of the abdomen, the 

 latter glabrous. Abdomen and propodeum brown, washed slightly with metallic
