SCATOPSE. 179 



A female in the same collection from Yunnan, South China, 

 almost certainly represents the same species, and I have seen a 

 pale-legged variety taken bv" Mr. Imms at Bhowali, 5700 ft., 

 20. vi. 20, running over Iris leaves. 



Types in the Indian Museum. 



Subfamily SCATOPSIN^. 



The distinctive characters of this subfamily have already been 

 given, on page 159. 



There is only one genus that occurs in the Orient, Scatopse, 

 Geoff. These are small or minute flies of slender delicate 

 structure, generally black or with a dull reddish tinge about 

 the abdomen ; the wings very transparent. The very distinctive 

 venation renders them easily recognisable. 



Genus SCATOPSE, Oeoff.

 Scathopse, Geoffroy, Hist, abreg-ee Ins. ii, p. 544 (1762), (two 

 species mentioned without names). 



Genotype, Tipula notata, L. ; by designation of Latreille 

 (1814), as T. alhipennis, Y. 



Head exceedingly small, rounded, enlarged behind. Proboscis 

 not prominent. Palpi unobtrusive, indistinctly jointed, the last 

 joint rather large. Eyes kidney-shaped bare, approximate in 

 male, the frons being therefore very narrow. Ocelli distinct. 

 Anteunje porrect, as long as, or shorter than, the thorax, ten- 

 jointed ; 2nd scapal joint cup-shaped, the last flagellar joint oval, 

 the remainder short ; bare of pubescence, the whole antenna more 

 or less club-shaped. Thorax arched, transverse suture absent, but 

 the front third of the dorsum puffed up and protuberant. Scutellum 

 short and broad. Abdomen approximately linear, rather wider 

 behind, of seven or eight segments, pointed in the female. 

 Genitalia generally distinctly visible. Legs very short and 

 comparatively robust. Pore femora obviously thickened, fore 

 tibiae unarmed, posterior tibiae often clubbed; hind metatarsus 

 shorter than the four remaining joints taken together. Pulvilli 

 sometimes very small. Winr/s distinctly broad, longer than the 

 abdomen, folded upon each otlier in repose, very thin and 

 transparent, sometimes almost invisible. Venation somewhat 

 ditticult of determination with exactitude, and a new interpretation 

 of the veins is ventured upon. The two strong veins near the 

 anterior border are recognised by all as the 1st and 3rd longi- 

 tudinals, the latter often originating from the 1st in such a way 

 that its basal section appears as a "cross-vein" (much as is 

 apparently the case in Sciara). I am disposed to consider that 

 the anterior cross-vein is absent and that the strong vein
