Thorax blackish grey, hardly at all shining and not at all striped, 

 the anterior extremity and humeri being more ashy grey ; pubescence 

 composed of rather abundant but not dense short depressed pale grey 

 hairs which become longer and conspicuous above the wing-bases and 

 on the postalar calli down to the scutellum, and which grow more 

 longer and shaggier on the humeri and praea'ar calli ; there are rather 

 abundant suberect longer stiffer black hairs intermixed all over the 

 thorax, these black hairs inconspicuous on the disc unless viewed side- 

 ways, but stand out long and conspicuous between the humeri and 

 wing-bases. Scutellum similar to the thorax in colour and clothing, but 

 the pale grey pubescence fairly long and conspicuous round the margin. 



Wings clearly hyaline, very slightly pale yellowish about the 

 base and fore part, with pale yellowish veins which are slightly tinged 

 with brownish towards the ends ; upper branch of the cubital fork with 

 a very short reccurrent veinlet ; anal cell closed a long distance before 

 the margin ; first posterior cell widely open but slightly narrower at the 

 wing than at the middle part. Squamae pale greyish white somewhat 

 hyaline, with a yellow margin to the alar pair and a whitish margin 

 to the thoracal pair, and with the usual tuft near the angle whitish 

 yellow in accord with the tuft on the upper part of the metapleurae, 

 and with somewhat conspicuous very short and sparse pale yellowish 

 white marginal fringe on the thoracal pair ; halteres pale yellow, with 

 dull coloured knob. 



Legs dull blackish brown and pale orange yellow, but the femora 

 and coxae rendered grey by abundant dust ; trochanters brownish 

 orange ; about- the apical one-third (or more than that in the front femora) 

 of all the femora, the basal half or fourth of the front tibiae, all the 

 posterior tibiae (except the faintly darkened tip in the hind one), and 

 the base and underside of the posterior tarsi, pale reddish yellow ; 

 front tarsi deep black ; bare space beneath the front femora shining 

 orange yellow and the row of minute black bristles on its inner margin 

 inconspicuous. Pubescence mostly greyish white, short and rather
