Primary with veins 6, T, 8 stalked, U and lu on a long stalk from just before 

 the end of the cell, 11 long bent upwards and lying directly below vein 12. 

 Secondary with two internal veins. 3, 4 and 5 from angle of cell, 7 from the cell, 

 connected with 8 by a bar, 8 bent upwards from the base in a deep curve, then 

 sharply downwards to the bar, from thence to the margin at an angle, it thus 

 forms a large secondary cell, several small veinlets are emitted from 8 to the 

 margin, a slight precostal vein.

 area, deep purplish red below the cell to the inner angle ; snbbasal line curved, 

 dark grey, evanescent a little below the cell, postmedial line dark grey, angled

c?. Palpi hairy, porrect not beyond the frons ; antennae deeply bipectinate for 

 about a third, suddenly decreasing, and gently tapering to tip ; legs hairy, one pair 

 of minute spurs on hindtibia only. 



Primary with veins 4 and .5 from lower angle of cell, 6, 7 and S stalked, 

 9 and 10 on a very long stalk, 11 inclined up and lying directly below 12. 

 Secondary with two internal veins, 3, 4 and 5 from the lower angle, 4 and 5 

 being stalked, 7 from the cell near to the base, 8 bent down to touch 7 close to 

 its origin from the cell, then angled rapidly upwards to the costa, so forming 

 a small secondary basal cell, two veinlets rising from 8 before its anastomosis, 

 precostal vein also present.
