AUSTIIALIAX HTMEXOFTEEA CllAU'lDOIDEA. IV.—GIEAULT. \s» 



the latter at caudal eud, the pair formiug au ol'late splicre i^hose axis is tlie median eariiia; 

 this carina originates cejilialad some distance from the median carina and is thin there and 

 more or less broken. True lateral carina present but running oppositely, thus caudodaterad ; 

 the latter carina is narrowly connected with the curved carina of the mesa! area by a cross- 

 carina at about cephalic third. Spiracle minute, round. Seutellum with a foveate median 

 groove, terminating at apex as a carina. Parapsidal furrows complete. Pronotum transverse 

 linear. Caudal tibial spur single, normal. Postmarginal vein twice the length of the very 

 small stigmal. Axillas only very slightly advanced. Abdomen (in death) with its dorsal 

 surface applied to the dorsal surface of the thorax. Scutum shorter than the seutellum, 

 wider than long. 



1. PARAHORISMENUS SPISSIPUNCTATUS new species. Genotj-pe. 



Female: — Length, 1.70 mm. 



Dark metallic blue, the thorax with a trace of coppery; proximal three tarsal joints 

 white; fore wings deeply smoky from base distad nearly to apex of marginal vein, distad 

 the infumation suttused, not clearly delimited; hind wings smoky for nearly proximal two 

 thirds. Marginal vein about twice the length of the submarginal. Scajie slender, longest; 

 pedicel rather long, subequal to funicle .3; funicle 1 longest of the fiagellum, nearly twice 

 longer than wide, rather stout, slightly longer than 2; club 1 longer than 2, the latter with a 

 distinct terminal spine. Caudal and intermediate tibia with stiff bristles dorsad. Abdomen 

 flat, dorsal aspect rounded oval, segment 2 longest, occupying somewhat less than half the 

 surface. Abdomen and propodeum glabrous, the liead and thorax umbilicately punctate, the 

 parapsides finely shagreened except along all margins. Parapsidal furrows foveate. Petiole 

 very short, wider than long, glabrous. Hind coxa glabrous. Mandibles with at least two 

 outer acute teeth. Thorax covered with rather thick black-brown pilosity. Punctures on head 

 smaller and less dense.

HabUat: Tweed Heads (Tweed Eiver), New South Wales (.<ft! below). 



Type: No. Hy 3490. Queensland Museum, Brisliane. the specimen on a tag; head and a 

 caudal leg on a slide. 



Also one female. Grafton (Clarence River). New South Wales, .Tune 3, 1914 (A. P. Dodd). 



nOKISJIEXELL.V new genus. 



Female: — In my table of genera runs to Phurotroiiopsens Girault but differs in having 

 the postmarginal vein elongate; the lateral carina of jiropodeum is not V-shaped but entire 

 and a short curved carina just nresad of spiraide originates laterad of the cephalic end of the 

 lateral carina. The median groove of scutum is along distal two thirds or somewhat more. 

 Caudal tibial spur long, stout and curved, longer than the first tarsal joint of caudal legs. 

 Postmarginal vein over thrice the length of the stigmal, the latter subsessile; marginal vein 

 over twice the length of the submarginal. Otherwise the same as originally described for the 

 named genus. Segment 2 of abdomen occupying a little less than a fourth of the surface, 

 over twice the length of 3; strigils absent. Three ring-joints; really runs to Fleurolropomyia. 



1. HORISMENELLA CLARIVIRIDIS new species. Genotype. 



Female: — Length, 1.90 mm. 



Bright metallic green, the abdomen dark blue except segments 2 and 3; legs, scape and 

 abdominal petiole silvery white, the coxa) and petiole suffused with orange. Fore wings with 

 an obscure dusky spot in the center of the blade opposite the stigmal vein. Funicle 1 longest, 

 2 and 3 each shortening a little, 3 longer than the pedicel, over twice longer than wide, longer 

 than club 1 ; club 2 somewhat shorter than tlie pedicel, with a distinct but not very long
