Tibiae short and stout, two-thirds the length of the stout and 

 short femur; tarsus long and slender, longer than tibia. Basal 

 joint of tarsus the longest, longer than second, third, and fourth 

 united, which, together, are of the same length as fifth Spurs 

 as long as first joint. In forewing, Cuo and lA run parallel to 

 Cui for some distance. Crossveins in the costal area of forewing 

 simple. Branches of radial sector not forming any straight line. 

 In hindwing, two rows of cells between Cu^ and hind margin.

Front part of vertex much raised. Wings hyaline, with 

 brownish-black or golden shining spots or bands. Hind margin 

 of wing with two excavations, the apical one the deeper. Costal 

 area rather narrow, with simple crossveins, from the pterostigma 

 broader, and with forked crossveins. Five or six crossveins 

 before origin of radial sector in the forewing, one in the hind- 

 wing. The somewhat bent branches of radial sector tend to form 

 a straight line through the middle of the apical part of the wings. 

 Legs slender; first tarsal joint about twice the length of second,
