AUSTRALIAN HYMENOPTEBA CHALCIDOIDEA, VI.— GIRAULT. 329 



Genus POLYCYSTOIDES Girault. 



1. POLYCYSTOIDES TENNYSONI Girault. 



A female May 14, 1914 by sweeping in forest, Gordonvale. General color black. The 

 fore wings are a little stained proximad. The suture across scutellum is really a ridge and 

 has the appearance of being the apical margin. Type re-examined. The latter is a female 

 on a tag, the head and hind legs on a slide. It measures 2.50 mm. and was taken April 13, 

 1913. 



Genus HYPOPTEEOMALUS Ashmead. 



1. HYPOPTEROMALUS VIRIDESCENS (Walsh). 



In the detailed description of this North American species given in the Bulletin of the 

 Wisconsin (U.S.A.) Natural History Society, x (1912), on page 25, second line from bottom, 

 Cephalic aspect should read Dorsal aspect. 



2. HYPOPTEROMALUS DUBIUS new species of Girault and A. P. Dodd. 



Female: — Length, 1.25 mm. 



Differing from the detailed generic description (see . Bulletin of Wisconsin (U.S.A.) 

 Natural History Society, vol. x, 1-2, June, 1912) in lacking the median carina of the propodeum 

 and the obscure cross-suture on the scutellum; the first funicle joint is small, like a ring- joint 

 and much smaller than the second; and the abdomen, viewed from lateral aspect, is not almost 

 triangular, its ventral margin being but gently convex. 



Very dark metallic green, almost black; the propodeum (except at meson) and the 

 abdomen much brighter green, the latter suffused with brown; coxaa and femora brown; 

 tibisa, tarsi and antennal scape golden yellow; rest of antenna? fuscous. Wings hyaline, 

 venation as in Hypopteromalus viridescens (Walsh). Mandibles 3 and 4-dentate, the teeth 

 acute. Head somewhat wider than thorax; thorax rather short and broad, not much longer 

 than wide; scutum fully twice as wide as long, the parapsidal furrows only indicated 

 anteriorly; scutellum, viewed from lateral aspect, distinctly convex. Propodeum rather short 

 and broad; lateral carina? inconspicuous; spiracles not large, with rather delicate spiracular 

 sulci. Thorax rather finely reticulated, the reticulation in raised lines. Abdomen somewhat 

 shorter and narrower than thorax; petiole short; second segment occupying one third of the 

 surface; remaining segments about subequal. Pedicel distinctly longer than any of the 

 funicle joints; first funicle joint small; second distinctly larger; 2-6 subquadrate, wider than 

 long; club barely twice as long as wide, the three club joints about subequal. 



Described from one female caught by sweeping in forest, August 13, 1913 (A. A. Girault). 



Habitat: Gordonvale (Cairns), Queensland. 



Type : No. Hy S79S, Queensland Museum, Brisbane, the specimen on a tag, the head 

 and a hind leg on a slide. 



SPHEGIPTEKOSEMA new genus. 



For diagnosis, see antea (these Memoirs, II), p. 323. The genotype is a new species. 

 It measures 1.90 mm. and was taken in May, 1913. Its type is on a tag, the head and hind 

 legs on a slide. ^ 



1.5 SPHEGIPTEROSEMA AUSTRALIENSIS new species of Girault and A. P. Dodd. 



Female: — Length, 2.50 mm. 



Head and thorax very dark metallic green, almost black, the coxse concolorous; rest of 

 legs bright golden yellow; abdomen metallic purplish, its petiole yellow; antennal scape and 

 pedicel yellow, rest of antenna? black. Antennas 13-jointed, with two ring and three club
