I contend it must be admitted that the I st vein normally and actually 

 ends in the 2nd, because whenever the costal cross vein is absent it most 

 obviously does so end. 



STIBADOCERELLA, gen. nov. 



Near Stibadocera, Enderl. Antennae with similar very long and 

 conspicuous verticils the whole length of the flagellum, w^hich consists 

 of 13 joints, the last three not so distinctly demarcated as the others ; 

 scape as in Stibadocera. Thorax absolutely without trace of punctula- 

 tion. All tibiae with very small spurs. Palpi comparatively short, 

 all the joints apparently subequal. Auxihary vein turning up very dis- 

 tinctly into costa ; subcostal cross vein distinctly present ; 1st vein 

 turning down into 2nd as usual in this section ; no trace whatever of 

 costal cross vein ; 2nd and 3rd veins diverging very late, half way be- 

 tween anterior cross vein and wing tip. As the wing is absolutely colour- 

 less (in the type and only species) all the veins stand out with striking 

 clearness. 



Genotype : S. fristina, sp. nov. ^ $ from Assam. 



Stibadocerella pristina, sp. nov. 

 (^ 9- Assam. Long. 10 mm. 



Head pale yellowish, face with a greenish tinge ; palpi brownish, 

 paler at tip ; antenna^ scape yellowish, flagellum brown. 



Thorax pale brownish-yellow, very smooth and shining, traces of 

 three shining, rather dark brown median, subcontiguous stripes, less 

 distinct in $• 



Abdomen dirty brown, hind margins of segments narrowly whitish, 

 more distinct in (^, and broader on the long 2nd and 3rd segments. 

 (There seems no clear demarcation between what are apparently the first 

 three segments.) Tip of abdomen blackish ; genitaha in ^ small but 

 distinct ; in $ comparatively large, bulbous at base, the valves black, 

 shining. 



Legs. — Coxae greenish (hght verdigris colour) ; rest of legs brown. 

 Femora a httle pale at extreme base, and slightly thickened towards 

 tips ; tibiae with a very narrow white ring at extreme base (in one ^ 

 the ring is greenish) ; front tibiae with broad white ring at tip, where 

 the pubescence is longer and thicker. Tarsi snow-white, anterior 

 metatarsi brown except extreme tips, hind metatarsi brown to just 

 beyond middle. 



Wings absolutely colourless, veins extremely distinct, in accordance 

 with the generic diagnosis ; halteres black, stem comparatively long. 



Described from four (^ <^ and one $ in Indian Museum from Tura, 

 Garo Hills, Assam, 3,500—3,900 ft., vii-17 {Kemj)).
