Winged viviparous female - Body castaneous browo, abdomen ful- 

 vous, pronotum with 2 short yellowish stripes; antennae pale fulvous, 

 ths 3rd anb 4th each with 3 and the 5th with 4 broad incomplete rings, 

 anterhinarial nearly as broad as long, its rhinarium being round and 

 small, at the apex with a few short hairs; wings hyaline, stigma grayish, 

 veins fulvous, except the media, each on the sides more or less clouded, 

 at the basal half media being obsolete, stigma sword-like, ending not 

 distinct by at the apex, stigmatic nervure at the base very broad and 

 conspicuous; hind-wings with 2 :: narrow pale fuscou veins, which are 

 nearly broad as the media of the fore-wings, the inner one of which 

 being longer, nearly in the same level, each other with 2 booklets on 

 the costa; legs pale fulvous.

 After studying the venation of it concisely I have found that some induviduals of this 

 species have exceptionally only one oblique to the hind wing.
