9 Head (figs. 2, a. & e.) with small flat grey scales forming a broad 

 border around the eyes and with similar flat scales at the sides, in the 

 middle small dull golden narrow curved scales and fine black upright 

 forked scales behind. Palpi (fig. 2, g.) short, brown, testaceous beneath ; 

 proboscis brown, the testaceous hue present as in the palpi ; clypeus 

 (fig. 2, h.) pale yellowish brown ; antennte ( fig. 2, d.) brown, basal 

 segment pale yellowish-brown, very pilose between the verticels. 

 Thorax bright ferruginous clothed with narrow-curved mouse-colored 

 and dull golden scales and with numerous bristles of a more or less dull 

 hue ; scutellum (fig. 2, c.) bright testaceous with small narrow-curved 

 scales as on the thorax ; seven border-bristles to the mid lobe, meta-

 than the second posterior, its stem more than half the length of the cell, 

 its base a little nearer the apex of the wing ; stem of the second posterior 

 as long as the cell ; scales on the upper branch of the fourth vein rather 

 broader than elsewhere. Posterior cross-vein nearly twice its own 

 length distant from the mid ; mid and supernumerary meet at an angle. 

 Halteres pale, with faintly fuscous knob.
