420 Mr. E. E. Austen on new 



jowls yellowish ^VGy, a dark brown horizontal mark between 

 antenna and eye on each side ; clove-brown lateral frontal 

 spots conspicuous, in contact with eyes, produced downwards 

 and inwards towards frontal callus, which they often touch, 

 median frontal spot small but distinct, a narrower lighter 

 (sometimes olive-grey) median stripe extending upwards 

 from it on to vertex ; frontal callus dark mummy-brown, of 

 moderate depth, extending from eye to eye, upper and lower 

 margins nearly straight, dark brown spot in middle line 

 below callus not very distinct ; palpi dark brown or greyish 

 brown, clothed with brownish hairs, terminal joint elongate, 

 more or less cylindrical, but little expanded at base ; fir-t 

 joint of antenna light mummy-brown, shining and strongly 

 incrassate, inner margin convex when seen from above, 

 second joint russet, its upper angle moderately prominent, 

 third joint wanting. Thorax : dorsum with indications of 

 three narrow lighter stripes, pleural and pectus mouse-grey. 

 Abdomen : venter greyish brown ; extreme hind margins of 

 segments on ventral as well as dorsal surfaces usually paler ; 

 dorsal and ventral surfaces clothed with short brownish hair, 

 ■with sparse yellowish hairs, longer towards distal extremity, 

 near hind margins of segments. Wings : oblique light marks 

 across first four posterior cells usually broken up into two 

 spots in each cell ; light markings along hind margin, if 

 present, small and inconspicuous, sometimes distinguishable 

 in distal angles of first, second, third, and fifth posterior 

 cells and at tip of sixth longitudinal vein ; stlyma well- 

 marked, long, dark brown, no light mark at its proximal 

 extremity (except a minute and scarcely visible fleck at ex- 

 treme tip of second costal cell), but a clearly defined though 

 incomplete circular or oval light mark immediately beyond 

 it; discal cell with a very small light fleck in its proximal 

 angle and with two widely separated transverse light marks, 

 the proximal mark curved, with its concave side towards base 

 of wing, the distal mark broken up into a pair of spots ; 

 basal cells each with a pair of transverse light marks, wider 

 apart in case of second basal cell, near tip of which there is 

 sometimes also an ill-defined light mark ; an angulate and 

 sinuous light streak running across axillary and anal cells, 

 and a semicircular light mark in proximal angle of axillary 

 cell. Halteres seal-brown, stalk cream-buft*. Legs : femora 

 dark brown ; front tibiae and tarsi clove-brown, with a broad 

 cream-coloured band close to base of former ; middle and 

 hind tibiffi and tarsi brown, two bands on tibiae, first joints of 

 tarsi except tips, and bases of next two joints cream-buff; 

 front tibiae not incrassate.
