Discussion. — This species is much smaller and more poorly marked 

 than the other known Oriental species, with narrower wings and 

 duller and more of a grayish ground color. The genitalia are similar 

 to those of maculitibia Lane and Forattini from Panama in the struc- 

 ture of the parameres, but the dististyles of maculitibia are blunt 

 tipped.
