AUSTRALIAN HYMEN OPTEEA CHALCIDOIDEA, IV.—GIRAULT. 26T 



2. ENTEDONOMORPHA SUBFUSCIVENTRIS new species. 



Female: — Length, 1.60 mm. Compared with types of tennysoni and renani. 



Differing from tennysoni Girault in being stouter, in having the abdomen but obscurely 

 yellowish centrally (dorsal aspect), in having the first two femora fuscous and submetallie 

 and in being nearly black, not evidently metallic green. Also, the scutum is distinctly longer 

 than wide (cephalic end), the parapsidal furrows cephalad curving off before attaining the 

 pronotum (in tennysoni, the scutum is wider than long cephalad, the gouge-like parapsidal 

 furrows attaining the pronotum at the latter 's extreme latero-caudal angle). The hind wings 

 are about twice broader (about ten lines of discal cilia). Abdomen with some yellowish just 

 before apex ventro-laterad. Grooves of scutellum curving toward each other slightly, at apex 

 (somewhat closer in tennysoni) . Spiracle of propodeum situate centrally, between the arms of" 

 a V-shaped carina just laterad of the lateral carina, the mouth of the V opening laterad. 

 Petiole of abdomen longer and stouter, with a median and dorso-lateral sulcus. Otherwise as 

 in tennysoni. Scutum subglabrous cephalad. Pronotum uniformly sculptured. Cephalic femur 

 nearly black, much darker than middle. 



From one female taken in jungle, August 7, 1913 (A. P. Dodd). 



Habitat: Gordonvale (Cairns), Queensland. 



Type : No. Hy 2658, Queensland Museum, Brisbane, the specimen on a tag, head and' 

 hind legs on a slide. 



In this genus the axilla? are not advanced and the ' ' true lateral carina ' ' of propodeum. 

 is a curved sulcus. 



3. ENTEDONOMORPHA UNICA new species. 



Female: — Length. 1.60 mm. Differs from the genotype in having two spurs on the- 

 caudal tibiae. 



Dark metallic blue, the abdomen wholly dark metallic green, the wings hyaline; scape 

 and legs very pale yellow except cephalic femora and coxa? and sides of middle coxa?. Differs 

 from subfusciventris in having the hind coxa? not brown, the abdomen not suffused with red 

 yellowish, the pronotum is a little more coarsely sculptured, densely punctate, the grooves of 

 scutellum are separated at apex only by a narrow space, the abdomen is shorter, nearly 

 round from dorsal aspect, the petiole shorter, segment 2 occupying two thirds of the surface ; 

 the mandibles are 5-dentate. On the propodeum there is a short (abbreviated) carina from 

 caudal margin between the median carina and the curved sulcus which represents the lateral 

 carina (present in subfusciventris) . Otherwise the same. 



From one female caught in jungle, June 25, 1914. 



Habitat: Gordonvale (Cairns), Queensland. 



Type: No. Hy2659, Queensland Museum, Brisbane, the specimen on a tag, head audi 

 hind legs on a slide. 



A second female, same place, July 11, 1914. 



4. ENTEDONOMORPHA VARICORNIS new species. 



Female: — Length, 2.40 mm. 



Very dark metallic green, the abdomen reddish yellow broadly margined dorsad and 

 ventrad with black, the mesal reddish area broadening distad. Scape and legs white, the 

 hind coxa dark metallic. Pedicel and funicle 1 reddish yellow, funicle 2 suffused with reddish. 

 Scutellum purplish, its grooves widely separated at apex as in subfusciventris, the foveaa of 

 each groove united so that the sulcus is nearly continuous (distinctly broken somewhat distad' 

 of middle). Abdomen conic-ovate. Hind tibial spur single, distinct. Mandibles 4-dentate, the- 

 mesal two teeth small. Fourth club joint very short, obtuse, the lateral spur minute, present,-
