AUSTRALIAN HYMEN OPTEBA CHALCIDOIDEA, IV.—GIBAULT. 229 



Genus TKICHAPOBOIDELLA Girault. 

 Synonym: Aprostoceroloides Girault. 



1. TRICHAPOROIDELLA DECORA Girault. 

 This species belongs to N eotrichaporoides Girault which see. 



2. TRICHAPOROIDELLA DUBIA Girault. 

 The type specimen was taken November 3, ]912. 



3. TRICHAPOROIDELLA SPECIOSUS (Girault). Genotype of Aprostoceroloides. 

 The median groove of scutum is absent. Type re-examined. 



4. TRICHAPOROIDELLA MARGIVENTRIS (Girault). 



From Aprostoceroloides. Type re-examined. The marginal stripe of abdomen is dark 

 metallic green. A second female taken in the type locality, November 7, 1913 bore two dots 

 in a longitudinal line on meson of abdomen, distinctly distad of the apex of the marginal 

 stripes. Median carina of propodeum long and thin. 



5. TRICHAPOROIDELLA PARTICOLOR new species. 



Female: — Length, 1.20 mm. Slender. 



Dark metallic green, the wings hyaline, the legs white, the hind coxa washed with 

 metallic above; ventral half of head, propleura, prepectus, tegula, cephalic margin of meso- 

 pleurum, an ovate spot filling center of abdomen at base, meson of abdominal venter and 

 sides of abdomen at proximal third, honey yellow. Propodeum coarsely scaly, with a distinct 

 median carina, the sculpture nearly punctate, rougher than the rest of the thorax; caudal 

 and lateral margins carinated. Funicle joints each shortening; 1 elongate, nearly as long 

 as the club (three fourths its length), much longer than the pedicel which is somewhat shorter 

 than joint 3 which is much longer than wide. 



From one female caught November 3, 1912 on banks of the river. Jungle. 



Habitat: Proserpine, Queensland. 



Type: No. Hy2573, Queensland Museum, Brisbane, the specimen on a tag, the antenna 

 on a slide. 



6. TRICHAPOROIDELLA RADIUS new species. 



Female: — The same as eleganta in stature and so forth but differing in the following 

 particulars: The stripe down meson of pronotum is somewhat narrower, the scutum the same 

 but the large green marking is obtusely conical there leaving distinctly more than the lateral 

 margins yellow (the space between lateral margin of scutum and lateral margin of the green 

 marking at cephalic margin is twice broader) ; the stripe down meson of scutellum is somewhat 

 narrower, the spot on axillae oval and thus smaller while the abdomen though similarly margined 

 bears only three complete cross-stripes, one distad of ends of marginal stripes with a 

 cephalic projection at meson (and slight ones at each margin), one joining the ends of the 

 marginal stripes and one preceding this farther proximad; between this first stripe and base, 

 two cross-stripes are slightly indicated by short projections mesad from each margin. Lateral 

 margin of propodeum margined, the lateral carina? absent, the median distinct. 



In eleganta, the cephalic half (or nearly) of each parapside, except along lateral 

 margin, is metallic green. In radius, the cephalic third of that sclerite is metallic green; the 

 scape except at tip is yellowish; rest of antenna dusky black.
