AUSTRALIAN BYMENOPTEIIA CHALCIDOIDEA.—GIEAULT. 223 



meson quadrately and along its cephalic margin ; there is a transverse, narrow 

 black line across scutellum just before its apex, but abbreviated laterad, running 

 between the two bristles ; rest of scutellum and caudad to abdomen lemon yellow. 

 On the abdomen six very distinct black stripes, the first and second often 

 combined, the distal two with cephalic convexities at meson. Tlie axillae may 

 have a more or less distinct fuscous blotch cephalad. Pronotum lemon yellow. 

 Orange yellow. Funicle 2 only somewhat longer than 1. The species runs very 

 close to novisexfasciata Girault and is very likely the same. From the types of 

 the genotype of Calocyha. 



Genus BKACHYSCELIDIPHAGA Ashmead. 



Removed from the Pteromalida;. The original description of the genotype 

 is correct. The spot on the scutum is subovate or longer than wide and a little 

 caudad of centre at the meson ; the spot on the inner angle of the parapside is 

 over the caudal end of that sclerite and the cephalic end of the axilla. The 

 scutellum is brown-black except lateral and apical margins broadly; the abdomen 

 is "dusl<y or brownish" dorsad only, except at base where there is a yellow 

 triangle on each side of the meson, the apex mesad. The marginal vein is about 

 a half longer than the stigmal. Caudal tibial spur single. Postmarginal vein 

 slightly longer than the stigmal, the marginal longest. 



Differs from Coeloc}ihella Girault in bearing but a single caudal tibial 

 spur, the stigmal vein is longer in proportion to the marginal and the three ring- 

 joints gradually enlarge. It comes closest to TricJiilogaster but that genus should 

 bear two caudal tibial spurs (e.g., ater does) and the marginal vein is thickened. 

 Differs notably from Coelociihclloides in lacking one caudal tibial spur. 



From the types. 



PARACCELOCYBA new genus. 



Genotype: Ccelocyha acincta Girault. Transferred from the Pteromalidae. 

 Includes C. varifasciaia Girault and the following species. 



Differs from CoeJocubomyia in lacking a sclerite between scutellum and 

 postscutellum and one caudal tibial spur and in bearing a solid club. 



PARACOELOCYBA MINUTA new species. Female. 



Smaller than usual. Length, about 1.00 mm. Bright orange yellow, the 

 following parts black: Distal half of abdomen ventrad and dorsad, three 

 narrow cross-stripes on proximal dorsal abdomen (or distal fourth is black above 

 and below, proximad dorsad with four stripes), the first just out from base and 

 interrupted on each side of the meson ; a line across upper face of pronotum and 

 lateral margin of propodeum. Scutum, scutellum and parapsides studded with 

 short, black hairs as in the other species. Caudal aspect of head, postscutellum 

 and propodeum lemon yellow. Second tibial spur very small, distinct. Mandibles 

 tridentate. Three ring-joints; funicles 1-2 subequal, the others gradually 

 enlarging, 5 largest, much wider than long, 3 and 4 subequal. Wings hyaline, 

 the venation pale yellow. Antenna! club apparently solid. Antennse inserted 

 at the clypeus. 



Described from four females captured by sweeping "fir bushes" in 

 blossom, forest lowlands, Brooklyn, New South Wales, November 1-9, 1914. 

 A common species.
