220 MEMOIRS OF THE QUEENSLAND MUSEUM. 
NEOEURYS BREVIVALVIS sp. nov. 
? Colour metallic black with a slightly greenish tinge on head and thorax 
yellow are mandibles, front of labrum, all the sterna including hypopygium of 
abdomen as w r ell as the lateral portions of the terga, and the apices of the 
femora ; rest of legs yellowish white infuscated on apices of tarsal segments, 
ings hyaline; stigma pale brown with basal half white; venation brown. 
Length 4*8 mm. ; forewing 4*5 mm. ; antenna 1*2 mm. 
Puncturation. — Head and thorax shining unpunctured except for small 
hair follicles ; abdomen transversely rugulose. 
Head. Clypeus with front margin entire ; malar space about as long as 
apical breadth of jDedicel ; antenna 9-segmented, subclavate ; pedicel longer 
than broad (in proportion of about 5:3); median fovea deep in front, 
continuing back as a groove as far as front ocellus. Legs with hind basitarsus 
about equal to three following tarsal segments in length. 
Abdomen laterally compressed and kom the side appears truncate at the 
apex because the sawsheath is set up erect (fig. 6a) ; saw of normal type but 
simplified (fig. 6b). 
Queensland, Brisbane, 1$ (Holotype), 17-ix-1914, and 1$ (paratype), 
8-ix-1915, H. Hacker (holotype in Queensland Museum, paratype in British 
Museum). 
This species would run dowm in my key to N . ventralis Forsius (Tasmania), 
which is a larger species in which the sawsheath is normal in position and the 
saw is more complex (see Benson 1934 (2) p. 476, fig. 6f for sawsheath and 
fig. 9b for saw). 
NEOEURYS AURORA sp. nov. 
$ Colour : metallic black with green reflections on head and thorax ; 
yellow' are mandibles and labrum, flagellum of antenna on underside from 
apical half of segment 4, apex of femora, tibiae and on front and middle legs 
bases of, all tarsal segments on hind legs, only basal half of basitarsus, and 
apex of abdomen from segment 7, except the medial dorsal portion of segment 
7 and 8. Wings hyaline, stigma light brown at the apex with the basal half 
white, venation browm. 
Length 3-5 to 4 mm. ; forewing 3-5 to 4 mm. ; antenna 1-3 mm. 
Puncturation. — Head and thorax dull with a rough coriaceous surface, 
actual punctures being for the most part ill-defined and irregular. 
Head. — Clypeus entire in front ; malar space about as long as apical 
breadth of pedicel ; antenna 10-segmented, subclavate ; pedicel longer than 
broad (in proportion of about 5:3); median fovea deeply impressed and
