344 EMPIDiE. 



black at tips of femora and tarsi; soft yellow pubescence on legs, 

 no conspicuous bristly hairs. Wings pale grey ; stigma in- 

 distinct, brown ; halteres black. 



Length, 3 mm. 



Described from a single <$ in the Indian Museum from Sukna, 

 base of Darjiling Hills, l.vii. 1908 (Annandale). 



An immature specimen, probably a 2 5 from near Bhowali, 

 Kumaon, Western Himalayas, taken by Dr. A. D. Irams, 

 13. vi. lyiO, is apparently this species. 



Subfamily EMPI1M. 



Eyes normally contiguous or subcontiguous in male, well separated 

 in female ; in some species narrowly but distinctly separated in 

 both sexes ; the frons in the male in such cases sometimes, but not 

 always narrower than in the female. Proboscis varying from a 

 little shorter than height of head to longer than whole body; palpi 

 1-joiuted. Antenna? 3-jointed, with two-jointed style. 



Thorax of moderate height ; metapleura with bristles, except in 

 Hilara* 



Axillary lobe of wing well developed, except occasionally ; 3rd 

 longitudinal vein simple or forked, 4th vein forked ; lower branch 

 of 5th longitudinal vein recurrent, approximately parallel with 

 bind margin of wing, meeting anal vein at an obtuse angle, making 

 anterior margin of anal cell the longer ; anal vein of varying 

 length. Pour posterior cells ; a discal cell; basal cells subequal ; 

 anal cell shorter than 2nd basal ; squamae small or absent. 



Members of this subfamily may be recognised by the elongated, 

 downwardly directed proboscis in conjunction with the lower 

 branch of the 5th longitudinal vein being parallel to the hiud 

 margin of the wing. It includes the largest species of the family 

 (Empis and MJtamphomyia, but both genera include also very small 

 species).

Third longitudinal vein forked. [p. 345. 

 Auxiliary vein not reaching wing-border; 

 upper branch of 3rd vein forming a wider 

 angle with lower branch, often nearly at 

 right angles to it ; fore tarsi in male not 

 dilated (or at most only very slightly 

 swollen) ; metapleura with bristles .... Empis, L., p. 347. 

 Auxiliary vein reaching wing-margin ; upper 

 branch of 3rd vein forming a smaller angle 

 with lower branch, sometimes almost 

 parallel with it; fore tarsi in male dis- 

 tinctly dilated ; f metapleura bare Hilaea, Mg., p. 357. 



Howlettia, Brun., is not included in the table of genera, being 

 anomalous, but is retained temporarily in this subfamily.
