the rest of the tarsus) pale yellow. Wings barely as long as 

 abdomen, rather broad, tip rounded, pale grey ; costal vein very 

 distinct, ending at tip of lower branch of 3rd vein, immediately 

 before the extreme tip of the wing; auxiliary (subcostal) and 1st 

 longitudinal veins thick, the former ending at about two-thirds 

 of the wing, the latter a little beyond it, both nearly straight, 

 distinctly separate (though approximate) from just beyond the 

 humeral cross- vein ; the 2nd and 3rd longitudinals with the 

 anterior cross-vein have the appearance of springing from a 

 common stem (or else the 3rd longitudinal and the anterior cross- 

 vein spring simultaneously from the 2nd vein at a little beyond its 

 base) ; 2nd vein nearly straight, but curved upward at its tip, to 

 the costa ; 3rd vein nearly straight, and in a straight line with 

 the prsefurca, forking widely towards its tip, and becoming 

 suddenly much thinner, both branches ending in the costa 

 distinctly before the wing-tip ; anterior cross-vein short, near 

 base of discal cell; 4th longitudinal vein forking just before 

 anterior cross-vein ; upper branch nearly straight for more than 

 half its length, thence with a slight curve, forked, the upper

prong erect, closing 1st posterior cell, lower prong running to 

 wing-margin ; lower branch of 4th vein also comparatively 

 straight, forked so widely towards its tip that the prongs are 

 nearly in the same straight line with one another, upper one 

 closing discal cell, lower one joining upper branch of 5th vein 

 towards its tip, closing 3rd posterior cell. Posterior cross-vein 

 very short, placed at about middle of discal cell ; 5th vein 

 thickened, forked near its junction with posterior cross-vein; 

 lower branch closing anal cell. First basal cell rather large and 

 broad, bounded distally by the anterior cross-vein; 2nd basal 

 cell much longer and narrower, bounded distally by the posterior 

 cross-vein; discal cell elongate, about 3 J times as long as its 

 greatest breadth. The 1st submarginal cell nearly as long as the 

 'marginal and narrowed at wing-margin ; 2nd submarginal cell 

 small, subtriangular. The 1st posterior cell embraces the wing- 

 tip, but the upper prong of the upper branch of the 4th vein 

 divides the cell at two-thirds of its length; 2nd posterior cell 

 large, of irregular shape; 3rd closed, much wider distally; 4th 

 subtriangular, formed by the branches of the 5th vein ; anal vein 

 slightly curved ; axillary vein short, axillary cell large. Alulae
