* The specimen figured seems to be intermediate between the type (as de- 

 scribed by Smith, and figured by Westwood) and the variety from Mindanao 

 described by Westwood {I. c. p. 120). The fore wings are brown, hyaline at the 

 base as well as the tip, and a slightly oblique central fascia of uniform breadth 

 runs from below the costal nervure to the inner margin. Hind wings hyaline, 

 with the apical third brown. This species is remarkably similar to 0. amazo- 

 nicus, Westw.
