AUSTRALIAN HYMEN OPTEBA CHALC1D0IDEA, V.—GIBAULT. 305 



3. CCELOCYBOMYIA PERSIMILIS new species 

 Female: — Length, 1.75 mm. 



Like the preceding species but the stripes on the abdomen differ in that they are 

 distinctly narrower (much over their width apart, not as in the allied species) and the sixth is 

 represented by a mesal dot only ; also the black line across apex of scutellum is absent, that 

 across cephalic margin of the propodeum also absent. The antenna? differ in the length of the 

 j3edicel. The face is indexed in both species. 



Unfortunately before noticing the specific identity of this species its head was mounted 

 with the only head of novisexfasciatus and the antenna? became mixed. One species has a 

 longer pedicel than the other. 



Described from one female mounted with the above and from the same source. 



Habitat: Melbourne. Victoria. 



Type: In the National Museum, Melbourne, the above specimen and a slide bearing a 

 head as stated. 



4. C(ELOCYBOMYIA NIGRIVENTRIS new species. 

 Female: — Length. 2.65 mm. 



Orange yellow, the head, pronotum, the transverse sclerite following the scutellum, the 

 postscutellum, caudal third or more of each parapside, distal margin of abdomen dorsad, legs, 

 venter of abdomen, scape and propodeum transversely meso-cephalad greenish-yellow. Wings 

 hyaline. Upper half of occiput, venter of thorax, dorsum of abdomen except distal margin, all 

 dorsal thoracic sutures except that between pronotum and mesonotum and between axilla? and 

 parapsides and the propodeum jet black. A black' spot at cephalic margin of axilla centrally. 

 Flagellum brownish, closely resembling that of the type species. Mandibles distinctly tridentate.. 



Described from many females reared from galls on young gum, March 11. 



Habitat: Melbourne, Victoria. 



Types: In the National Museum, Melbourne, two females on a tag. 



The genus resembles Ccciocyba Ashmead but the scutellum is more flat and there is a 

 transverse sclerite between it and the transverse postscutellum. Also, the marginal, postmarginal 

 and stigmal veins are longer. 



XEOPERILAMPUS new genus, Girault and Dodd. 



Female: — Differs from Epiperilampus Girault in that the axilla? are widely separated. 

 1. NEOPERILAMPUS NIGER new species of Girault and Dodd. Genotype. 



Female: — Length, 2.60 mm. 



Jet; scape lemon yellow; tibiae and tarsi white. Scutum and scutellum with line polygonal 

 s<:-a]y sculpture. Parapsidal furrows deep, very widely separated; axilla? with their mesal angles 

 just mesad of the meso-caudal angles of the parapsides. Scutellum long, distinctly convex. 

 Propodeum glabrous, with a faint median carina and distinct lateral sulci. Abdomen almost 

 smooth but with a few scattered setigerous pin-punctures, the second segment occupying nearly 

 a half of the surface. Venation yellowish, the wings hyaline, the marginal vein thickened, the 

 stigmal not short, nearly as long as the marginal, the postmarginal somewhat longer than the 

 stigmal. Mandibles bidentate, the inner margin of the second tooth obliquely truncate. 

 Antenna? 13-jointed, inserted near the middle of the face, with two distinct ring-joints, the club 

 3- jointed. Eing-joints very transverse. Funicle 1 slightly shorter than the pedicel, subquadrate, 

 joints 2-6 all much wider than long. Club joints wider than long. 



Described from one female taken in jungle, July 21, 1913 (A. P. Dodd). 



Habitat: Gordonvale (Cairns), Queensland. 



Type: No. Hy2754, Queensland Museum, Brisbane, the specimen on a tag, the head on a 

 sli de.
