Obscure lutea, margine antica thoracis albida ; antennis maris et feminse capite fere 

 duplo longioribus ; alis f'usco-luteis, venula transversa marginali ante medium pedunculi

Length of body 5 — 6 ram. 



,, wing 5 "5 — 6 "5 mm. 



Loc. Seychelles. Mahd : forest between Trois Freres and Morne Seychellois, 1500 

 —2000 ft., XII. 1908, 1 $; Mare aux Cochons district, 1500 ft., I. 1909, 2 $, 1 ?. Two

25. Anisomera ferruginea, sp. n. (Plate 10, fig. 16, wing.) 



Tota ferruginea, alis cum pedibus infuscatis ; antennis maris capite subduplo longiori- 

 bus ; venula transversa marginali in apicem cellulse submarginalis primge inserta. 



$. Head ferruginous ; eyes, palpi and flagellum of antennae black ; antennae short, 

 barely twice as long as the head, 6-jointed. Thorax ferruginous ; legs black, coxae ferru- 

 ginous, base of femora lighter. Wings smoky, somewhat narrower than in the precedmg 

 species, veins all dark and clearly marked ; first submarginal cell as long as its petiole, 

 marginal cross-vein inserted at its base. Halteres dark fuscous. Abdomen entirely

This and the preceding species are the first of the genus recorded outside of Europe 

 and America. 



Loc. Seychelles. Mahe : Mare aux Cochons, 1 ^ ; Cascade Estate, 1 $. 



There is in the British Museum a single specimen of an insect from Selangor, which 

 to the naked eye would easily pass as A. ferruginea, but looked at closely it is seen to 

 have 14-jointed antennae and only one submarginal cell. It has, however, spurred tibiae, 

 and only three posterior cells, as has Anisomera, and hence seems to be a species of 

 Cladolipes. 



Genus Eriocera Macquart, Dipt. Exot., i. 74 (1838). 



26. Eriocera obscimpennis, sp. n. (Plate 10, fig. 17, wing.)
