This sub-genus is in the greatest confusion and a 

 recent paper by Fruhstorfer (Berl. Ent. Zeitschr. XLIY. 

 pp. 121 — 155 1899) has not cleared matters up very 

 much ; in fact until the opposite sexes of several of the 

 species have been taken in coitu, the numerous types 

 compared and the genital armature of the males dissected 

 out no satisfactory revision of the sub-genus can be 

 made. 

 From Borneo seven species have been recorded : —

3. ,, diardi, Voll.
