The ultimate tergite of the male before us is large, produced 

 caudad, forming a large, blunt cone, the ventral margin beneath 

 transverse, above that of the subgenital plate. 



In the present material of this large and handsome species the 

 tegmina are translucent ochraceous-buff, in the male with proximal 

 veins of marginal field whitish as originally described; in the female 

 these organs are uniform warm buff. The wings are striking^ 

 bicolored, as is normal for the species.
