Type in the Indian Museum. 



Osten Sackeu (Monog. Dipt. N. Amer. iv, p. 104) notes the 

 varying position of the 8rd vein in some Euro])ean and North 

 American species, on account of which the anterior cross-vein is 

 at times obhterated. Such a species {E.favipes, Macq.) is figured 

 by Needham. 



304. Rhamphidia unicolor, sp. nov. 



S . Head with the eyes approximate, leaving a distinct yellowish- 

 grey, moderately narrow frons. Proboscis light brownish yellow, 

 with golden yellow pubescence ; palpi concolorous, with similar 

 pubescence. Antennal scape brownish yellow, nearly bare, joints 

 elongate; flagellum blackish, with grey pubescence, the joints 

 gradually becoming attenuated. Xeck long, pale whitish yellow. 

 Thorax pale shining yellow, with a slight trace of a narrow median 

 darker line ; sides concolorous, less shining. Abdomen pale yellow 

 with whitish pubescence ; belly of similar colour, as are also the 

 inconspicuous and apparently normal genitalia. Legs wholly pale 

 yellow, barely darker to^vards the tips of the tarsi. Winf/s pale 

 yellow, veins deeper yellow. Venation differing from that" of the 

 previous species by the greater length of the basal portion of the 

 ;^rd longitudinal vein, the anterior cross-vein being about as long 

 as in E. ferrugiiiosa ; the discal cell shorter, and more nearly 

 square. Halteres yellowish white. 



Length 4 millim. 



Described from a single specimen from Darjiling, 8. viii. 09 

 (Paiva). 



Type in the Indian Museum. 



In the slightly different length of the basal portion of the 3rd 

 longitudinal veil], we see in this species an approach towards the 

 extinction of the anterior cross-vein referred to bv Osten Sacken as 

 characteristic of certain European and North American species. 



305. Rhamphidia inconspicua, sp. nov. 



6 . Head blackish grey ; frons apparently about one-fifth the 

 width of the head (the eyes being crushed inwards). Proboscis 

 _ about as long as the head, dark brownish yellow, the black palpi, 

 which are rather small, situated at its tip. Basal joint of 

 flagellum ovate, the remainder long and slender, very in- 

 distinctly separated. Thorax: upper surface wholly 'moderately 

 light yellowish brown, the sides dirtv yellowish. Abdomen 

 dirty yellowish, pubescent. Genitalia' dirty brownish yellow, 

 large, apparently normal. Legs dark brownish yellow, lighter 

 on the coxa? and at the base of the femora. Wings nearly 

 clear. The auxiliary vein ending in the 1st longitudinal at two- 

 thirds the length of the wing, the subcostal cross-vein being
