third longitudinal vein and inner end of discal cell; great cross- 

 vein situated a little before inner end of discal cell. 



Hah. — Barron River, Northern Queensland (Froggatt). A 

 single damaged specimen. 



Genus 21. Conosia, v.d. Wulp. 



Conosia, v.d. Wulp, Tijds. v. Entom. XXIII., p. 159, pi. x.,

Two sub-marginal cells ; five posterior cells ; a discal cell ; 

 auxiliary vein very long ; sub-costal cross-vein situated before its 

 tip a distance about equal to length of great cross-vein ; marginal 

 cross-vein joining the first sub-marginal cell near its inner end ; 

 small C7'0ss-vein sititated at or beyond the distal end of the discal 

 cell. Palpi short, one-jointed. Antennae 12-jointed. Tibiae 

 without spurs ; empodia distinct; ungues long, smooth. 



The palpi clearly consist of only one joint (PI. xxiv., fig. 60, 

 mouth parts) though Van der Wulp states that there are four, and 

 figures them. Rostrum extremely short. Antennae short, about 

 one-third longer than the head ; first joint thick, cylindrical, 

 about one-third the length of entire antennae ; second globose, as 

 wide as the first ; third somewhat narrower, ovate ; fourth and 

 following joints small; the fourth globose, the rest gradually 

 becoming more elongate until the terminal one is almost linear and 

 about twice the length of the next preceding joint ; verticillate- 

 pilose (PI. XXIV., fig. 61). Van der Wulp says "antennae 14-arti- 

 culatse," but I think that the slender terminal joints have deceived 

 him. The head is flattened, somewhat longer than broad ; front 

 broad, with an impressed line on each side ; eyes round. Thorax 

 gibbose, rather long, strongly projecting over the hinder portion of 

 the head ; a distinct small pit on each side behind the humeri ; scu- 

 tellum rather large, almost the width of the thorax ; metathorax 

 somewhat steep. Abdomen long, slender, cylindrical ; male forceps
