d $ . Head : frons yellowish grey or yellowish, from one-third 

 to one-fourth the width of the head. Proboscis brownish yellow ; 

 palpi blackish. Antennae brownish yellow, normal in length, 

 shape and pubescence, sometimes the apical half of the flagellum 

 a little darker. Thorax wholly yellowish, the dorsum almost 

 imperceptibly darker, with two irregular rows of dorso-central 

 bristly hairs. Scutellum and sides of thorax yellowish, metanotum 

 sometimes a little brownish. Abdomen brownish yellow, with 

 rather numerous pale yellow hairs at the sides. In some specimens 

 there is a blackish streak towards the sides ; in others the narrow 

 internal organs can be readily seen showing black and twisted 

 through the transparent integument. Belly similar. Genitalia 

 of male brownish yellow, pubescent ; 1st joint large, subcylin- 

 drical ; 2nd joint short, with a long bifid claAV. Ovipositor 

 brownish yellow, normal, only moderately enlarged at the base ; 

 terminal blades long, slightly curved. Legs pale yellow, tarsi 

 generally no darker, but in some specimens almost imperceptibly 

 so towards the tips. Wings yellow, pubescence of veins distinct, 

 venation nearly normal ; the posterior branch of the 4th longitu- 

 dinal vein forks early, the veinlets both gently bisinuate (which is a 

 slight deviation from their usual course in this genus) and approxi- 

 mately in the same direction; the 7th vein, after quitting its 

 proximity to the 6th, runs practically parallel, though gently 

 bisinuate, with the hind margin of the wing. Halteres yellow, 

 the clubs quite black.
