370 EMPJDJE. 



one on the shoulder, one towards the hind corner of the dorsum, 

 and one about equidistantly between these two, this middle pah- 

 being rather closer to each other (that is, to the middle line of the 

 thorax) than the others are, yet still a considerable distance apart; 

 there is also one on the side of the thorax, in front of the wing ; 

 scutellum with two bristles. Abdomen dark brown, almost devoid 

 of pubescence. Legs wholly pale yellow ; fore femora much 

 enlarged, fore coxae and fore tibiae each very slightly longer than 

 the fore femora, the latter being spiny and bristly below ; hind 

 tibiae very slightly enlarged, at the tip only. Wings very pale 

 grey, a little yellowish towards base and costa, unmarked. 



Length, 2 mm. 



Described from one $ in the Indian Museum taken by me at 

 Darjiling, 7000 ft., 29. v. 1910, on the hillside, in mixed herbage.

.Head with epistome produced downwards, pointed ; eyes rather 

 large, somewhat elongate, widely separated in both sexes, with 

 dense short pubescence ; proboscis short, thick ; palpi 1-jointed. 

 Antennae 3-jointed, placed just above "middle of head, all the joints 

 short and minutely pubescent ; 2nd with bristles ; 3rd rounded, 

 somewhat disciform, with long, curved, rather thickened arista, 

 which possesses a minute ring-like basal joint. Thorax rather 

 elongate, with rounded anterior angles, moderately arched. Uni- 

 serial dorso-central bristles, a humeral, post-humeral, notopleural, 

 and postalar bristle present, and two scutellar bristles ; metapleura 

 bare. Abdomen 8-segmented ; the two anal segments reduced and 

 partly concealed by the male genitalia; abdomen in female pointed. 

 Legs slender; fore coxae slightly elongated, about half as long as 

 femora. Legs minutely pubescent ; tibia? without spurs ; two 

 pulvilli and a small linear bristle-bearing empodium. Wings 

 with auxiliary and 1st longitudinal veins short, the former 

 reaching the margin ; 2nd vein long ; 3rd vein forked, the upper 

 branch united to 2nd vein towards its tip ; lower branch of 5th 

 vein strongly recurrent, almost immediately meeting anal vein 

 (which is very abbreviated, not nearly reaching wing-margin), 

 making anal cell very short and truncate. Dorsal cell very elon- 

 gate, 2nd basal cell very short, much shorter than 1st basal and 

 subequal to anal cell ; three submarginal, four posterior cells ; hind 

 angle of wing quite reduced, making it almost cuneiform. Ground- 

 colour of wing brown, with hyaline spots. 

 Range. Europe, India, North America. 



A limited genus of small delicate Empids, easily recognised by 

 the brown wings with pale spots.
