800 DIPTERA OF AUSTRALIA, 



Rather more than a dozen genera, chiefly American and 

 European, are referred to this section ; a few of them doubtfully. 

 Some of them, as remarked by Baron Osten-Sacken, seem to 

 exhibit the aspect of the Limnophilina. Conosia is one of these 

 puzzling genera. Outside of America and Europe very little has 

 been done amongst the Eriopterina. Dr. E. Bergroth has recently 

 described about half a dozen species from South Africa, for one 

 species of which he erects the new genus Podoneura ; only three 

 species have hitherto been recorded from Australia, two belonging 

 to the genus Trimicra, and one to Gno2)homyia. 



Genus 11. Rhypholophus, Kolenati.

" Two sub-marginal cells ; four posterior cells ; discal cell present 

 or absent. Wings pubescent on the ivhole surface. The second 

 longitudinal vein originates at a more or less acute angle, before 

 the middle of the anterior margin ; the sub-costal cross-vein is a 

 considerable distance (two or three lengths of the great cross-vein) 

 anterior to the tip of the auxiliary vein. Antennae 16-jointed. 

 Tibise without spurs at the tip ; ungues smooth on the underside ; 

 empodia distinct." (Osten-Sacken.) 



Sub-genus, Amphineurus, sub-gen. nov. 



No discal cell. Posterior branch of fourth longitudinal vein 

 forked ; base of the fork (third posterior cell) situated at or a 

 little before base of second posterior cell ; the second and third 

 posterior cells running almost to a point at the base. Second 

 longitudinal vein arcuated or angulated at its origin, sometimes 

 with even a short stump of a vein ; the sub-costal cross-vein 

 situated only a short distance beyond this origin. 



In the main characters these insects appear to agree with 

 Rhypholophus, but the peculiar modification of the second and 

 third posterior cells, constant in both species, is a distinctive
