Antennffl 8-jomted, the club apparently 2jointed; funiele joints 1 and 2 very short, 

 3 and 4 each longer than 1 and 2 together. The following species is, more or less, doubtfully 

 included. 



1. ARCHENOMUS BIGUTTATUS new species. 



Female: — ^Length, 0.77 nun. 



Black, the scutum and scutelluni silvery white, the former with a large, wider than 

 lono- black area from cephalic margin across meson of more than cephalic third; axilla; black, 

 forming a lateral pair of roundish spots on middle of thorax. SeutellUm (apparently) with a 

 narrow lateral groove. Cephalic femora, cephalic and intermediate tibi® and the tarsi whitish; 

 tips of caudal tibia; wliitish; antennas pale yellow, the scape and pedicel black. Fore wings 

 with a distinct dusky stripe across from the marginal vein, the stripe accented just caudad of 

 ai)ex of that vein, the latter rather thick, distinctly shorter than the submarginal and prac- 

 tically truncate at apex, the stigmal vein obsolete. A naked area on fore wing just disto- 

 caudad of apex of venation. Marginal fringes of fore wing tolerably short, not more than 

 a fifth the greatest wing width, shorter than the caudal fringes of the hind wing; the latter 

 with a pair of lines of discal cilia which fade distad. the base of the blade infuseated. Vertex 

 yellowish. Eyes bulging, coarse, round. Flagellum filiform, no distinct club, the second 

 funiele joint like a thick ring-joint, not half the length of the small pedicel, the other flagellar 

 joints long, subequal, each somewhat over twice longer than wide and longitudinally striate. 

 Mandibles liroadly truncate but with a median sinus. Scape only slightly longer than funiele 

 1. Antennas 9-jointed. with the ring-joint. 



From one female caught in forest. May lo, 1914 (A. P. Dodd). 



Habitat: Chindera (Tweed River). New South Wales. 



Type: No. Hy SyGS, Queensland JIuseum, Brisbane, the female on a slide. 



NEOCASCA new genus. 



Female: — Differs from BanlyJif: Howard in bearing a ring-joint in the antenna and 

 in having the fore wings normal, that is. not long and curved and without long marginal cilia. 

 Marginal vein distinctly much siiorter than the submarginal. No hairless line. Middle tibial 

 spur small. Ovipositor inserted a little proximad of middle of abdomen. Scutelluni distinctly 

 wider than long. Marginal vein nearly thrice the length of the short stigmal. A short phragma 

 J I resent. 



1. NEOCASCA MULTIGUTTATA new species. 



Female: — Length. tl.OS nun. 



Golden yellow, the abdomen ]iale yellow, the wings hyaline, the legs eoncolorous, the 

 antenna; a little dusky. Hind femur at proximal half and the coxiE washed with dusky. A 

 flat triangle on pronotum at meson, the axillse (or at least a large elliptical spot apparently 

 upon them or covering them) and most of mesojileurum, jet black. Abdomen broadly dusky 

 down the meson and with five marginal spots from base to apex, dusky black. Legs 

 pallid, also the venation. Fore wings with about 22 lines of minute, rather dense discal cilia. 

 Proximal joint of middle tarsi distinctly longer than the others. Antenna; inserted not far 

 from the mouth, 8-jointed, the funiele 2-jointed, tlie club distinct, longer than the funiele 

 whose joints are a little longer than wide (joint 1) and somewhat wider than long (2); 

 pedicel a little longer than funiele joint 1. Scape moderate. Mandibles bidentate, the second 

 tooth obliquely truncate, broad.
