 hairs; pedicels very pale, almost white; two long hairs on side 

 of each basal swelling, opposite to the pectinations. Front with

 cross-vein r; a larger brown spot at origin of Rs; a large spot at 

 tip of 2nd A. Faint narrow seams along the cross-veins and 

 deflections of veins, especially on Cu, just above the fork of Cto. 

 Numerous pale grayish-brown dots sprinkled in most of the cells 

 (cells Sc and 1st M= excepted). (See fig. c). Venation: Sc 

 rather long, ending before the middle of Rs; cell 1st M^ small;
