base ; under-side of thighs beset with black bristles ; tips of shanks 

 armed with black spines ; claws black : wings colourless, dark brown 

 for one-fourth of the space from the base ; from this brown a broad 

 band of the same hue incloses a large triangular spot, and proceeds 

 obliquely to the fore border, which it accompanies to the tip of the 

 wing ; above the latter it includes three or four very small colourless 

 spots ; after an interval below this band two narrow pale brown bands 

 form an angle, which is nearly parallel to it ; wing-ribs and veins 

 tawny, the latter pitchy in the brown parts of the wing ; lower cross- 

 vein rather oblique, very slightly curved inward, separated by very 

 much more than its length from the middle cross-vein, which is 

 straight and slightly oblique ; poisers dark tawny. Length of the 

 body 2 lines ; of the wings 4i lines.
