 brown median stripe, this latter sometimes indistinct. Pleura reddish brown 

 with a sparse grayish bloom on the dorsal sclerites. Halteres pale, the knobs 

 dark brown. Legs with the coxae and trochanters dull yellowish, the margins 

 of the trochanters and the bases of the femora black; femora pale yellowish 

 brown, the tip broadly yellowish and including a rather broad subapical dark 

 brown annulus; tibiae and tarsi dark brown. Wings with a pale grayish tinge, 

 the costal cell more yellowish; large rounded brown markings or clouds as 

 follows: mid-length of Sc, at the origin of Rs, at the tip of Sc, at the stigma, at 

 the tip of R2+3; brown seams to the cord and outer end of cell 1st Mn; veins 

 brown excepting R between the dark markings where it is golden-yellow. 

 Venation: (see plate II, fig. 6) Sc long, extending about two-thirds the length 

 of Rs; Sco at the tip of Sci] Rs long, about four times the length of the basal 

 deflection of RaW, cell 1st M2 long and narrow, as long as the veins issuing from 

 it. 



Al)dominal tergites dark brown; sternites, especially the basal ones, paler, 

 more yellowish. 



Habitat.— Peru. Holotype, 9 , Matucana, Peru, altitude
