S . Head with vertex much elevated, light brown, the ocelli well 

 separated and very distinct, semi-transparent, with black centres ; 

 eyes light chestnut-brown, upper facets rather large, lower ones 

 very small and much darker brown ; eyes contiguous almost down 

 to the antennae, the Irons receding so much as to be invisible; 

 the inner sides of the eyes (seen from in front), also the face 

 below the antennae, blackish grey ; antennae, proboscis, and palpi 

 brownish yellow. Thorax moderately dark brown, with sparse 

 golden-yellow hairs on dorsum ; slightly paler at sides, and with

 of which the clearest is an oval one just beyond the stigma, 

 reaching from the costa to the fork of the 3rd longitudinal vein; 

 below this follows a spot in each of the 1st, 2nd, and 3rd pos- 

 terior cells ; there is a small one in the centre of the discal cell, 

 which, with a small one in the 4th posterior cell and a large one 

 in the 5th posterior cell, form, a row ; a small spot is at the tip 

 of the marginal cell, and a larger one at the tip of the submar- 

 ginal ; whilst the whole posterior border of the wing is pale grey, 

 spreading out somewhat in the cells and in the axillary cell. 

 The veinlets forming the upper fork of the 4th longitudinal vein 

 emerge practically together from the upper corner of the discal 

 cell, the outer side of which is practically quite straight. Halteres 

 light brown, with large blackish-brown knobs.
