188 MEMOIBS OF THE QUEENSLAND MUSEUM. 



OMPHALENTEDON new genus. 

 Female: — Like Mestocharis Foerster but the antenna: with three ring-joints. 

 1. OMPHALENTEDON LONGUS new species. Genotype. 



Female: — Length, 1.50 mm. Abdomen conical, somewhat longer than the thorax. 



Dark metallic asenous green, the broad fore wings hyaline, the legs (except cephalic 

 coxae) and the scape white. Petiole of abdomen brownish, wider than long. Thorax very 

 coarsely polygonally reticulate, the lines raised, finer on cephalic scutum, the pronotum scaly. 

 Propodeum glabrous, strongly tricarinate. Abdomen glabrous, hairy distad of segment 2 

 which occupies somewhat less than a fourth of the surface. Postmarginal and stigmal veins 

 short, subequal. Hind tibial spur normal. Parapsidal furrows along caudal half, obtuse. 

 Axillae much advanced but only about half projects cephaiad of scutellum. Pronotum trans- 

 verse-linear. Marginal vein twice the length of the submarginal. Pedicel subequal to funicle 1 

 which is one and a half times longer than wide, slightly longer than 2, 3 still shorter; terminal 

 ?pine of elub distinct, long. Club 1 subquadrate. Mandibles acutely bidentate. 



Male: — Not known. 



Described from one female captured in jungle, May 29, 1914. 



Habitat: Gordonvale (Cairns), Queensland. 



Type: No. Hy 2488, Queensland Museum, Brisbane, the specimen on a tag; head and 

 hind leg on a slide. 



MESTOCHAEOMYIA new genus. 



Genotype, Mestocharis lividus Girault. Includes Mestocharis veternosus and silvensis. 

 Each species bears a paired median carina on the propodeum; lividus has a middle short one 

 at base, also silvensis but the short carina is longer and split. In veternosus, the short third 

 middle carina is absent, the propodeum at meson with two separated carinas. Types re-examined. 



ENTEDONOPSEUS new genus. 



Female: — Agreeing in every particular with Entedonomyia Girault except that the 

 antennas bear three ring-joints and the two median carinas of propodeum are close together, 

 diverging only at apex. 



1. ENTEDONOPSEUS TRICOLORIPES new species. Genotype. 



Female: — Length, 1.65 mm. 



Agrees with the description of the genotype of Entedonomyia except that it is more 

 robust, the abdomen distad of segment 2 is coppery, the tibiae are metallic blue, orange at 

 tip, the tarsi white, their distal joint black. Also the hairs on scutum are black, funicles 2-4 

 are quadrate and subequal, each much larger than the pedicel, 1 only slightly longer than wide. 

 Club distinctly longer than any of the funicle joints. Type "antennae of Entedonomyia 

 compared. 



From one female taken from foliage of jungle plants, May 13, 1914 (A. P. Dodd). 



Habitat: Chindera (Tweed Eiver), New South Wales. 



Type: No. Hy2489, Queensland Museum, Brisbane, the specimen on a tag; head and 

 a caudal tibia on a slide. 



PARAHORISMENUS new genus. 



Female: — Like Horismenus "Walker but the antenna? with two ring-joints, the first large, 

 distinct, the second moderately short yet longer than usual. Propodeum with a median carina 

 bounded by sulci whose lateral margin is not distinctly carinated. Also in the mesal area a 

 curved carina on each side of the meson but some distance from the median carina yet meeting
