AUSTRALIAN HYMENOPTEBA CHALCIDOIDEA, IV.—GIRAVLT. 181 



Genus PLEUEOTEOPOMYIA Girault. 

 1. PLEUROTROPOMYIA LACTEICOXA new species. 



Female: — Length, 0.S5 mm. 



Like the genotype but much less robust and the petiole and the cox* are white also. The 

 median groove of scutum is shorter, along distal third (along distal half in the genotype). 

 The antennas in both species are much alike. Mandibles 4-dentate. Hind tibial spur a little 

 long and stout, as long as the first tarsal joint of hind legs which, however, is not especially 

 long. Compared with type of grotiusi. 



Male: — Not known. 



Described from one female captured by sweeping along edge of jungle, June 3, 1913. 



Habitat: Gordonvale (Cairns), Queensland. 



Type : No. Hy 2475, Queensland Museum, Brisbane, the above specimen on a tag, the 

 head and hind tibiae on a slide. 



2. PLEUROTROPOMYIA ffiNEOSCUTELLUM new species. 



Female: — Length, 1.75 mm. 



Almost exactly similar to the genotype but more brassy especially the scutellum and 

 the segments of the abdomen after the second are longer, 3 and 4 for instance when combined 

 as long as 2 (somewhat shorter in grotiusi) ; also in these abdominal segments, the single 

 transverse row of pubescence is along the cephalic margin in grotiusi but here it is central or 

 across the middle. Both species bear a distinct spiracular sulcus which originates just cephalo- 

 laterad of the minute spiracle; the axilla? in both and the triangular caudo-mesal corner of 

 each parapside are glabrous, also the postscutellum. The sulcus along meson of scutum in each 

 is about half the leugth of the scutum from caudad. Segment 7 of abdomen in both next 

 longest after 2 which occupies about a fourth of the surface. Hind tibial spur rather long 

 and stout. Compared with type of genotype. 



Male: — Not known. 



Described from two females captured by sweeping in forest, November 5, 1913. 



Habitat: Gordonvale (Cairns), Queensland. 



Type : No. Hy 2476, Queensland Museum, Brisbane, one of the above specimens on a 

 tag (minus head). 



Genus PLEUROTROPPOPSIS Girault. 



In antea, p. 154, table of genera, line 13, maculipennis should read maculatipennis. 



In the genotype the pronotum appears double owing to an obtuse cross-ridge a little 

 beyond middle; it is glabrous but with a row of long setae from small setigerous punctures, 

 the setae reclined and directed caudad over the scutum; this row of setigerous punctures is 

 cephalad of the cross-ridge. The wedge-shaped caudal part of each parapsidal furrow is 

 glabrous. Scutum with a few of the very long setae and one from about the middle of the 

 wedge of the parapsidal furrow. Axillae barely advanced, glabrous. Lateral margin of 

 scutellum earinated, forming a narrow groove just inside of the carina. From the type. 



Genus HORISMENOIDES Girault, 



Female: — With the form of the proctotrypoid genus Hadronotus but the abdomen still 

 broader. Venation, antennae and mandibles as in Amestocliaris Girault; ring- joints distinct. 

 Parapsidal furrows short but distinct, cephalad only; scutum with a complete, conspicuous 

 median sulcus. Scutellum simple, its cephalic margin triangularly advanced, the axillae obtuse- 

 conically advanced into the scutum, wholly cephalad of the scutellum. Propodeum very short, 

 with a median carina which is paired, apparently; lateral carinae apparently present, curved.
