AUSTRALIAN HTMENOPTEMA CHALCIDOIDEA, T.—GIEAULT. 303 



Gents KPIPKRILAMPUS Girault. 

 1. EPIPERILAMPUS ATER new species. -^ ^^ 



Fcmiilc: — Length, 2.10 mm. Rolnist, abilumeu stout, rounded. 



Wholly shining black, the Avings hyaline but ivith a slight brownish stain, rounded, just 

 Tinder the bend of the submarginal vein. Tarsi paler. Fuuicle 1 subquadrate. longest, 5 and 6 

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

 hidentate. Pedicel longer than any of the funiele joints. Stigmal and postmargiual veins 

 subecinal, 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 Ncoperilampn.i vigcr Girault and Dodd, besides 

 the generic character, in bearing the punctures on the scutum, in luiving the jjostmarginal vein 

 shorter, the tibiaj concolorous, the obscure spot on the fore wing, the first funiele joint shorter, 

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



In NeoiH'rilampus niger, with which I have compared this species (types), funiele 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 antenniB. Sides of pronotum more or less orange, also sides of scutiun. 



Male: — Not known. 



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

 edge of jungle, January 1.5, 1914 (\. P. Dodd). The species inhabits large cells in each gall. 



Habitat: Gordonvale (Cairns), Queensland. 



Types: No. Ht)S75J, Queensland Museum, Brisbane, three females on a tag; fragments

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

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

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

 funiele abrupt Ij' enlarged, a little longer than wide, somewhat larger than the pedicel, over twice 

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

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

 scaly. 



Male: — Not known. 



Described from about fifty females reared fmni |iointod galls on gum in November.

2. PERILAMPOIDES PARTICOLOR new species. 



Female: — Length, 3 mm. 



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

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