its lateral end at the caudal coxa; propodeal spiracle minute. Abdomen with 

 the petiole wider than long, subequal in length to the neck of the propodeum, 

 its second segment occupying about a fourth of the surface. Postmarginal vein 

 moderately long, distinctly longer than the subsessile stigmal. Mandibles triden- 

 tate. Parapsidal furrows complete, narrow. Pronotum not visible from above. 

 Scutellum with a single long bristle laterad a little distad of middle; scutum 

 with two long bristles, one on each side caudad. 



1, EPICHRYSOATOMUS UNFASCIATIPENNIS new species. Female. Genotype. 



Length, 1.50 mm. Dark aineous green, the antennae and coxce concolorous, 

 the legs reddish brown except the cephalic femur at about proximal two thirds 

 and less of the caudal femora, these parts of the legs washed with metallic 

 distinctly ; tibiae distad and the tarsi except at extreme apex, white. Scape long, 

 stout, curved; pedicel elongate, thrice longer than wide at apex, distinctly 

 longer than any following joint ; funiele 1 ovate, somewhat longer than wide, a 

 third shorter than 2 which is next longest of the flagellum. Club 1 next longest, 

 then 2 which is somewhat longer than funiele 1, club 3 slightly smaller than 

 funiele 1, bearing a distinct terminal spine as long as itself. Head and thorax 

 reticulated scaly, the lines raised; axill^B more finely so. Propodeum glabrous, 

 also segments 2 and 3 of the abdomen, the rest of the abdomen dorsad finely 

 scaly. Segment 3 of abdomen shortest, transverse-linear, 4, 5 and 6 subequal, 

 each about twice the length of 3. Fore wings with a distinct sooty cross-stripe 

 from the apex (moderately broadly) of the very long marginal vein and whole 

 of the stigmal, this stripe broadest at the middle, darker cephalad, narrowing 

 from the middle to each wing margin, hence more or less diamond-shaped. 



Described from one female captured November 5, 1914 by sweeping in 

 forest (low uplands, scanty grass), Brooklyn, New South "Wales. 



Type : No. Hy 3553, Queensland Museum, the specimen on a tag, the head 

 on a slide. 



Genus HORISMENOPSIS Girault. 



Genotype : HORISMENUS ANTIOPA Girault. 

 RHICNOPELTELLA PURPUREIVENTRIS new species. 



Female: — Length, about 1.80 mm. Robust, the ovipositor shortly 

 extruded. 



Differs from most of the species in being rather brilliant metallic green, 

 the abdomen, legs and face black-purple ; tarsi, except distal joint and the cephalic 

 knees, white. Wings hyaline, the venation fuscous. Body densely scaly. Middle 

 tibial spur long and slender, nearly as long as the basal joint of the caudal tarsus. 

 Tegute brown. Three distinct ring- joints which, however, increase in size, the 

 third a little less than half the length of funiele 1. Funiele joints increasing in 

 width distad but of about the same length, the middle one a little the longest, 

 the third somewhat less than half the length of the elongate pedicel. Abdomen 

 compressed. Club ovate, not longer than the funiele, obliquely truncate from 

 one side. Caudal tibial spur single. Club nippleless. 



Described from five females on tags in the United States National Museum 

 from Perth, "W. Australia. 



Types : No. Hy 3554, Queensland Museum, two females on tags plus a 

 slide with antenna? and hind legs. Paratypes: Catalogue No. 19145, U.S.N.M.
