tuse angle, parted from the second by six times its length ; second 

 very slightly curved, slanting, forming a very obtuse angle, longer 

 than the first ; third nearly straight, slanting, forming an almost 

 right angle; fourth very slightly curved, slanting, forming a right 

 angle, much longer than the third ; fifth very slightly curved, nearly 

 upright, forming a hardly acute angle. The description of C.

 a right angle, whence proceeds an additional longitudinal vein which 

 divides the second marginal areolet ; second slightly cuiTed, very 

 slightly slanting, forming an obtuse angle, a little longer than the 

 first, and parted from it by full thrice its length ; third hardly 

 curved, slanting, forming a slightly acute angle; fourth nearly 

 straight, slanting, forming an acute angle, shorter than the third ; 

 fifth curved, upright, forming a nearly right angle. In both wings 

 of the insect described an additional slanting cross-vein divides the 

 front areolet, and in the left wing there is an additional cross-vein 

 near the base of the sixth marginal areolet. Body black: head a 

 little narrower than the fore-chest ; crown adorned with an inter-
