the humeri to the postalar calli, passing on the praealar calli and the 

 upper bases of the wings, and their posterior halves with rather con- 

 spicuous brownish inner margins which extend from the upper corners 

 of the praealar calli to just after the anterior ends of the postalar calli ; 

 scutellum somewhat semicircular with the basal margin nearly straight, 

 covered with similar tomentum and hairs to the posterior border of the 

 thorax ; just above the wing-bases and on the lower margins of the 

 posterior calli there are the conspicuous long (but still short) whitish 

 grey tufts. Pleurae blackish but obscured by as .y grey tomentum, 

 and covered with short but longer than that on the disc of the thorax, 

 and erect whitish pubescence which grows slightly longer up to the 

 upper part and is intermixed with long erect stout black hairs on the 

 upper half of the mesopleurae ; on the prothorax and ptero-pleurae, 

 and on the postero-upper margins of the meso- and meta-pleurae 

 there are long dense shaggy whitish grey tuft. 



Wings about as long as the thorax and abdomen together, clear 

 with the costal cell and stigma yellowish brown, with the veins brown, 

 of which the radial and postical veins, and the stem of the cubital fork 

 more or less yellowish ; all the posterior cells widely open but the first 

 one more or less contracting towards the wing-margin ; discal cell 

 large and slightly longer than the second posterior cell, and anal cell 

 closed a long before the wing-margin ; the upper branch of the cubital 

 fork without recurrent veinlet. Squamae glassy grey in the alar pair 

 with a dark brown -margin and short and dense blackish fringe of 

 rather stout and erect hairs, and in the thoracal pair with a brown 

 margin and a short and sparse greyish fringe ; the tuft about the angle 

 yellow and long. 



Legs blackish, with the extreme apices of the femora, the basal 

 half of the front tibiae, and two pairs of the posterior tibiae, reddish 

 yellow ; front coxae moderately dilated and wholly two-thirds as long 

 as the front femora, covered with dense ashy grey tomentum and with 

 numerous long silvery white pubescence which becomes shorter apical-
