Genus ARCHENOMUS Howard. 
Antennz 8-jointed, the club apparently 2-jointed; funicle 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 mm. 
Black, the seutum and seutellum silvery white, the former with a large, wider than 
long black area from cephalic margin across meson of more than cephalic third; axille black, 
forming a lateral pair of roundish spots on middle of thorax. Scutellum (apparently) with a 
narrow lateral groove. Cephalic femora, cephalic and intermediate tibie and the tarsi whitish; 
tips of caudal tibiae whitish; antenne 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 
apex 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 
funicle joint like a thick ring-joint, not half the length of the small pedicél, the other flagellar 
joints long, subequal, each somewhat over twice longer than wide and longitudinally striate. 
Mandibles broadly truncate but with a median sinus. Scape only slightly longer than funicle 
1. Antenne 9-jointed, with the ring-joint. 
From one female caught in forest, May 15, 1914 (A. P. Dodd). 
Habitat: Chindera (Tweed River), New South Wales. 
Type: No. Hy 2963, Queensland Museum, Brisbane, the female on a slide. 
NEOCASCA new genus. 
Female :—Differs from Bardylis 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 shorter than the submarginal. No hairless line. Middle tibial 
spur small. Ovipositor inserted a little proximad of middle of abdomen. Sceutellum distinctly 
wider than long. Marginal vein nearly thrice the length of the short stigmal. A short phragma 
present. 
1. NEOCASCA MULTIGUTTATA new species. 
Female :—Length, 0.68 mm. 
Golden yellow, the abdomen pale yellow, the wings hyaline, the legs concolorous, the 
antenne a little dusky. Hind femur at proximal half and the cox washed with dusky. A 
flat triangle on pronotum at meson, the axilla (or at least a large elliptical spot apparently 
upon them or covering them) and most of mesopleurum, 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 funicle *2-jointed, the club distinct, longer than the funicle 
whose joints are a little longer than wide (joint 1) and somewhat wider than long (2); 
pedicel a little longer than funicle joint 1. Scape moderate. Mandibles bidentate, the second 
_tooth obliquely truncate, broad. 
From one female caught in forest, April 16, 1914 (A. P. Dodd). 
Habitat: Cloncurry, Queensland. 
Type: No. Hy 2964, Queensland Museum, Brisbane, the specimen on a slide.
