several small brown clouds ; the clear spaces in the wings almost 

 whitish ; a squarish space a little before origin of prsefurca, 

 followed by another of uncertain shape about middle of prsefurca ; 

 the fourth and fifth longitudinal veins are more or less distinctly 

 clouded at intervals with brown or brownish ; a rather prominent 

 brown spot at tip of anterior branch of second longitudinal vein ; 

 veins and stigma brown. Auxiliary vein reaching costa oppo- 

 site the middle of petiole of first sub-marginal cell ; the sub-costal 

 cross- vein opposite inner end of second sub-marginal cell ; sub- 

 costal cell a little expanded just before the tip of first longitudinal 

 vein ; prtefurca moderately long, straight except at the base ; 

 petiole of first sub-marginal cell usually about one-third the length 

 of the praefurca ; marginal cross-vein a little nearer inner end of 

 first sub-marginal cell than to tip of first longitudinal vein ; 

 branches of second longitudinal, particularly the posterior one, 

 arcuated ; second sub-marginal cell longer than the first posterior 

 cell by a distance equal to length of great cross- vein ; second 

 posterior cell about half the length of the first posterior cell; 

 great cross-vein at inner end of discal cell ; tips of fork of pos- 

 terior branch of fourth longitudinal considerably, and tips of fifth 

 and sixth longitudinal vein slightly arcuated ; seventh longitu- 

 dinal vein conspicuously sinuated.
