nate above on the inner side. Palpi prominent, incurved, 

 four-jointed ; first and second joints somewhat robust, first 

 joint small, second twice the length of the first, third rather 

 longer than the first and second taken together and consider- 

 ably more slender, fourth joint very slender, about equal in 

 length to all the others taken together. Antennae arcuated, 

 projecting forward, longer than the head and thorax combined, 

 very slender, 2 -f 14 jointed ; joints of the scapus of about 

 equal size, cupuliform, both setiferous at the apex ; flagellar 

 joints cylindrical, with a short dense pubescence. Thorax 

 oval, highly arched. Scutellum small, almost semicircular. 

 Metathorax high, acclivous. Abdomen slender, cylindrical, 

 six-segmented, with an anal joint almost as large as the sixth 

 abdominal segment, and small forceps. Legs long, slender ; 

 femora not so robust as the coxae, compressed ; tibiae spurred, 

 and the intermediate and hind pairs each with two rows of 

 lateral spines. Wings oblong-ovate, longer than the abdomen, 

 rounded off at the base, microscopically pubescent. Costal 

 vein extending far beyond the tip of the second longitudinal 

 vein, stopping a little before the apex of the wing ; auxiliary 

 vein joining the costa a little before the marginal cross-vein ; 

 the humeral cross-vein very oblique ; no subcostal cross-vein ; 

 first longitudinal vein joining the costa at a point three-fourths 

 of the distance from the root of the wing to the tip of the 

 costa ; the marginal cross-vein situated very much before the 

 middle of the first longitudinal vein, at a point about one-third 

 the length of the latter ; third longitudinal vein detached from 

 the second longitudinal vein, starting in the wing-disc con- 

 siderably beyond the marginal cross-vein, reaching the margin 

 much below the apex of the wing, without any trace of an 

 anterior branch ; fourth longitudinal vein joining the margin 

 before the tip of the first longitudinal vein joins the costa, the 

 only trace of an anterior branch being an indistinct short piece 

 of a vein quite detached from the fourth longitudinal vein, 

 and joining the posterior margin a short distance in front of 

 it ; fifth longitudinal vein only rudimentary. 



The only species of this genus hitherto described is from 

 Sydney, so the genus would appear to be confined to Austral- 

 asia.

Length of antennae, 0-055 ; size of body, 0-073 x 0-013 ; 

 expanse of wing, 0066 x 0030. 



Joints of scapus orange, with a few black hairs ; flagellum 

 black, joints froni three to five times longer than broad, 

 covered all over with a fine pubescence. Palpi light- 

 brown, darker at the tip. Thorax dark-brown or black, 

 covered with short yellowish hairs and longer black hairs,
