 long hairs. 



Wings a little shorter than body, nearly quite clear, with pale 

 brownish veins of which the mediastinal and radial veins, and stem of 

 the cubital fork, conspicuously yellowish, and with yellowish brown 

 stigma ; posterior cells all widely open, discal cell moderately wide and 

 shorter than the second posterior cell, and anal cell closed somewhat 

 long distance from the wing-margin ; the upper branch of the cubital 

 fork without the recurrent vienlet, but sometimes with the distinct one ; 

 mediastinal vein furnished with a row of very tiny black spines, and 

 the subcostal vein covered with numerous dense similar spines. Squa-

Legs rather narrow, blackish, with the extreme apices of the 

 femora yellowish, and with the about basal half of the front tibiae and 

 with two pairs of the posterior tibiae (except for the extreme tips 

 brown) pale yellowish white ; the front coxae very stout and wholly 

 two-thirds as long as the front femora, black obscured by an ashy 

 grey tomentum and covered with numerous rather dense long white 

 pubescence which becomes shorter and sparser apically ; the front 

 femora brownish black, slightly covered with a greyish tomentum but 

 slightly shining, and bearing numerous but not much dense very long 

 blackish pubescence which becomes considerably shorter on the inner 

 side, on the underside the narrow transversely striolate shining bare 

 space not hollowed out excepting on the extreme apex, and on the 

 inner margin of this subfemoral space there is a comparatively long
