 width of front at vertex just over 0-5 mm. ; length of portion of 

 palpi projecting beyond margin of buccal cavity 3-6 mm. ; length 

 of wing 10'4 mm. 



Diishy species, allied to and resembling G. fusca, Walk.,* but 

 distinguished by the pleurae being dark grey instead of drab-grey or 

 isabella-coloured , by the hind coxae being mouse-grey instead of buff 

 or greylsh-bu[f', and by the black hair fringing the posterior margin

 conspicuous fringe of fine hair, arista buff, dark brown beneath, 

 branched hairs nineteen in number in typical specimen ; palpi 

 dark mouse-grey on outer side, darker at tips, extreme base 

 buff; proboscis-bulb yellowish, with a dark brown blotch on its 

 upper lateral margin on each side. 



Thorax. — General coloration of dorsum clove-brown, owing to 

 usual longitudinal markings being well developed but not sharply 

 defined ; humeral calli and space on front margin on each side of 

 admedian stripes olive-grey, interspaces between clove-brown 

 longitudinal markings elsewhere light mouse-grey ; pectus of 

 same colour as pleurae ; scutellum as in G. fusca.
