sclerite obscure yellowish-brown with a J-shaped brown mark, the cross-bar be- 

 ing near midlength of the sclerite; lateral lobes of postnotum unmarked. Pleura 

 dark brown with a narrow and rather indistinct, pale brown, ventral, longitu- 

 dinal stripe. Halteres brown, the knobs darker brown. Legs with the fore coxae 

 dark brown^ only the base pale; mid- and hind-eoxae light yellow, the extreme 

 bases abruptly dark brown; trochanters light yellow; femora dark brown, paler 

 basally; a narrow post-medial yellow ring; immediately before the tip on outer 

 face a small, circular, yellow spot; tibiae yellow with three black rings, one sub- 

 basal, one medial and one apical, these blaek areas approximately equal in ex- 

 tent to the yellow interspaces; on one of the legs which had become detached the 

 outer yellow ring is obliterated; tarsi dark brown. Wing's light yellow, the 

 ground-colour almost obliterated by a pattern of dark brown spots and dots that 

 are confluent or nearly so over most of the surface, restricting the ground- 

 colour to abundant tiny spaces over the entire disc; a series of larger areas at 

 ends of veins Ri, K2 and R3 ; costal cell yellow with about eight brown spots 

 that are about as extensive as the interspaces ; similar large yellow blotches be- 

 tween the brown areas at ends of the radial veins; an ill-defined pale area in 

 cell R immediately before the cord; veins confonning in colour to the areas 

 traversed ; costal fringe inconspicuous. Venation : Besides the supernumerary 

 cross-vein in cell C, there are faint remnants of still other spurs in the dark 

 spots; Sc2 longer than Sci; Rs long, strongly arcuated at origin; R2_).3 short, 

 about one-half longer than r-m.; r almost obliterated by atrophy, about twice its 

 length from tip of Ri; inner ends of cells R3, Rs and 1st M2 in ali; 

 petiole of cell Mi short, about twice R2+3; cell 1st M2 long and narrow, 

 distally; basal deflection of Cui near midleng-fh; arcular crossvein distinct. 



Abdomen with^ the basal tergite light brown, dark brown laterally; second 

 tergite dark brown ; remainder of abdomen broken ; basal sternites pale brownish- 

 yellow.

This interesting fly is named in honour of the collector, Mr. G. H. Hardy. 



Gtnoplistia subimmaculata, n.sp. 



General colouration shiny black; antennae 18-segmented ; pleura and coxae 

 grey; femora yellow, the tips dark brown; wings subhyaliue, almost immaculate; 

 abdomen reddish-brown, the hypopygium and basal tergite dark. 



c?. Leng-th, 9.2 mm.; wing, 8.5 mm. 



Rostrum and palpi dark brown, the former with conspicuous yellow setae. 

 Antennae IS-segmented, the formula being 24-2-1-10-1-4, dark brownish black 

 throughout; pectinations of moderate length. Head shiny coal black. 



Mesonotum shiny black with greenish tints, the four usual stripes trans- 

 versely wrinkled; interspaces with yellow setae. Pleura almost entirely covered 

 with a microscopic appressed grey pubescence that appears like a heavy bloom, 

 the lateral selerites of the postnotum abruptly glabrous. Halteres pale brown, 

 the knobs a little darker. Legs with the coxae concolorous with the pleura; 

 trochanters dark brown; femora yellow, the tips conspicuously but rather narrow- 

 ly dark brown; tibiae brownish-yellow, passing into brown at the tips; tarsi 

 brown. Wings subhyaline, cell Sc darker; stigma small, brown, sending a small 

 seam across the fork of Rs; a tiny brown seam at origin of Rs; veins dark 

 brown; wing-base yellow. Venation: r-m very short, encroached upon by the
