AUSTRALIAN HYMENOPTERA CHALCIDOIDEA, V.— GIRAULT. 303 



Genus EPIPERILAMPUS Girault. 

 1. EPIPERILAMPUS ATER new species. 



Female: — Length, 2.10 mm. Robust, abdomen stout, rounded. 



Wholly shining black, the wings hyaline but with a slight brownish stain, rounded, just 

 under the bend of the submarginal vein. Tarsi paler. Funicle 1 subquadrate, longest, 5 and 6 

 widest, all after 1 wider than long; club wider than the funicle which widens distad. Mandibles 

 bidentate. Pedicel longer than any of the funicle joints. Stigmal and postmarginal veins 

 subequal, each somewhat shorter than the marginal. Hind tibial spurs double. Marginal fringes 

 of fore wing inconspicuous but present. Scutum with scattered thimble punctures. Venation 

 distad of submarginal vein pale. Differs from Neoperilampus niger Girault and Dodd, besides 

 the generic character, in bearing the punctures on the scutum, in having the postmarginal vein 

 shorter, the tibiae concolorous, the obscure spot on the fore wing, the first funicle joint shorter, 

 also the pedicel and in having the colorless distal part of the venation. 



In Neoperilampus niger, with which I have compared this species (types), funicle 1 is 

 longer than the pedicel, the ring- joints normal, not very transverse. 



Sometimes the cheeks and fore femora are reddish brown ; nearly always, the meson 

 of face ventrad of the antenna?. Sides of pronotum more or less orange, also sides of scutum. 



Male: — Not known. 



Described from three females reared from fleshy galls on young acacia or wattles, near 

 edge of jungle, January 15, 1914 (A. P. Dodd). The species inhabits large cells in each gall. 



Habitat: Gordonvale (Cairns), Queensland. 



Types: No. Hy2752, Queensland Museum, Brisbane, three females on a tag; fragments 

 of three heads and two hind legs on a slide. 



Genus PERILAMPOIDES Girault. 

 1. PERILAMPOIDES FLAVITHORAX new species. 



Female: — Length, 2.75 mm. 



Honey yellow, the abdomen brown except across immediate base, sometimes lighter at tip. 

 Head brown, the antennae and legs honey yellow. Pore wings hyaline but with a rather broad 

 yellowish brown stripe across it from about the distal third of the submarginal vein. Post- 

 marginal and stigmal veins subequal, slender, a little longer than the marginal. Scutellum with 

 a more or less obscure dusky spot near meson on each side at about distal third. Last joint of 

 funicle abruptly enlarged, a little longer than wide, somewhat larger than the pedicel, over twice 

 the length of funicle 4, the other funicle joints all plainly wider than long. Club joints large. 

 Axillae nearly or quite meeting at meson. Mandibles large, bidentate. Thorax finely reticulated- 

 scaly. 



Male:— Not known. 



Described from about fifty females reared from pointed galls on gum in November. 



Habitat: Melbourne, Victoria. 



Types: In the National Museum, Melbourne, three of the above specimens on a tag, a 

 head on a slide. 



2. PERILAMPOIDES PARTICOLOR new species. 



Female: — Length, 3 mm. 



Blue-black; scutum, parapsides, base of abdomen narrowly, axillae except centrally, apex 

 and cephalo-lateral angles of scutellum, orange yellow; also the legs (except coxae) and the sides 

 of thorax (more or less). Postmarginal vein as long as the somewhat thickened marginal, 

 distinctly longer than the stigmal. Axillae somewhat closer together, nearly meeting inwardly.
