apices rounded, ventral edge produced into a small angular point 

 about third from apex, a little below this a small process with round 

 apex arises from inner surface.

Wings half as long as tegmina, anal area forming stridulating organ. 

 $ Stramineous, eyes brown, fuscous on antennae, apices of tibiae 

 and sides of abdomen; tegmina white, opaque with waxy secretion, 

 veins yellowish, a black mark across tegmina, widest over base of 

 second and middle of first median sectors, eight small red dots on 

 costa, at second and third red dot a black mark through costal cell, 

 two small black spots near base, another in clavus, another at end 

 of clavus, from apex of costa to base of third median sectors a larger 

 black mark, black marks on hind margin near apex of median sectors; 

 wings white, opaque with waxy secretions, a black mark in middle of 

 hind margin. 



No medio-ventral process on pygophor, lateral edges roundly pro- 

 duced on sides of anal segment; anal segment longer than broad, apex 

 round, dorsal surface convex, ventral concave, anus near apex on ven- 

 tral side, anal style large, subcordate, concavo-convex, looking as if 

 apical portion of segment; styles shorter than anal segment, broad 

 at base narrowing to apex which is turned in and ends in a minute 

 fine spine with another slightly before apex, dorsal edge nearly entire, 

 ventral edge roundly produced on basal half. 



9 Anal segment very short, anal style large, subcordate.

In the description of the genitalia of this species the apex 

 of anal segment is described as ''angularly emarginate". This 

 would be more correctly described as being cleft nearly down to 

 anus, so that the apex is formed of two long ensate processes. 

 The lateral angular projection of the pygophor has a suture
