surface of the abdomen : the legs are long and stout ; the base of 

 the fore-thighs is brown ; the shanks and the first joints of the 

 feelers are very slightly curved : the wings are brown, and of mo- 

 derate size ; the rib-vein is black, and gradually widens into the 

 brand which is long and nearly spindle-shaped, but rather broader 

 at its tip than where it begins ; the hind-border near the tip is 

 curved, and does not form an angle ; the branch-veins are tawny ; 

 the fourth vein is curved and clouded at its base but afterwards 

 straight ; the third is obsolete at its source, and forked just be- 

 fore one-third and again a little after two-thirds of its length ; 

 the forks are more diverging from each other than in most species 

 of this group ; the first and the second veins are nearly straight, 

 and approach each other at their origin, but are far apart at their 

 tips ; in each upper wing there is a large brown spot proceeding 

 from the beginning of the brand into the disc of the wing, and 

 ending at the first fork of the third vein. 



Length of the body 1^ line ; of the wings 4 lines.

 the chest, and form a continuous transverse band : the body be- 

 neath is dull pale brown with a row of black dots on the sides of 

 the abdominal segments : the feelers are black, filiform, hairy,
