tibia) bispinose; togmina about as broad as tlio \vin<;s, apically 

 auipliated, tbc costal margin a little rounded, the apical margin 

 truncate willi tbc posterior angle subacutely produced, costal 

 membrane sliglitly wider tban radial area, tbe former somewhat 

 closely transversely' veined, tbe latter obliquely subreticulate, 

 two longitudinal veins emitted beneath radial vein, the lower one 

 forked at a short distance from base, tbe ujiper one bifurcate at 

 about one-third from base, nuist of tbe tegmen is obscurely trans- 

 versely reticulate, a distinct line formed of transverse veins near 

 apical margin defining a marginal series of narrow longitudinal 

 cellular areas : w ings with two transverse veins on apical area, 

 many of the longitudinal veins bifurcating outwardly.

Body and legs dull ochraceous : tegmina creamy-white, pale or 

 dark virescent and sometimes fawn-coloured (the last probably due 

 to discoloration), in the darker-coloured tegmina there is usually a 

 discal cretaceous spot beyond middle, and the anterior and apical

The produced posterior augles of the tegmina vary in length and 

 development, the specimen figured above showing the minimum in 

 that direction. 



Melichar has included in the synonymy of the above the species 

 described by Walker as Pcecilopiera culdita = P. plana, AV^alk., 

 which is not congeneric, an error the more strange as Walker has 

 referred to a figure given by Stoll as representing his P. addita.
