tinued proximad along i?2+3i uniting with the proximal arm at the fork 

 of Rs and thence continued caudad as a broad seam along the cord; the 

 distal arm is united along Ri with a mark that surrounds r and continues 

 caudad to vein R^\ a band at the level of the supernumerary cro^s- 

 vein in cell Ro, extends from costa to the caudal margin of the wing at 

 the end of vein i/3, paler and less distinct in the posterior cells; pale 

 brown clouds at the ends of all the longitudinal veins; a brown seam 

 along the outer end of cell Isl M^; a distinct grayish tinge in cells M 

 and Cu beyond the base; two or three small brown dots in cell 2nd A at 

 the wing-margin. 



Abdomen obscure yellow, the tergites margined laterally and 

 posteriorly with dark brown. Hypo]3ygium light brown.

 Sci alone longer than 7?2+.3; r far from the tip of R\ and at about one-third 

 the length of Ri\ R2+3 a little longer than the deflection of i?4+5, the 

 latter in alignment with the distal section of this vein ; petiole of cell M\ 

 but little shorter than the fork; cell 1st M-i about as long as the petiole of 

 cell M\\ basal deflection of Cu\ near mid-length of cell 1st Mo.
