Several specimens, coll. Pryer. 



In this species the width of central white or pale grey fascia, the 

 outline of dark fascia beyond, and the spot at apex are all subject to 

 modification. Some of the specimens are not separable from 

 European O. algira, others agree with O. stuposa, Fabr.

334. Ophiusa algira, var. curvata, v. n. (Plate LIII. fig. 8.) 

 Differs from the type in the outline of basal patch and central 



fascia ; the former has a deep indentation below the costa and then 

 descends straight to the inner margin, while the latter has a clear 

 curved exterior margin. The ground-colour of primaries is more 

 deeply suffused with violet. 



Three specimens, one of which is from Loochoo, coll. Pryer, and 

 the others were taken by my native collector at Gensan iu August 

 1887. 



Although showing some points of difference, I cannot at present 

 regard this insect as specifically distinct from O. algira.

I took examples iu Satsuma in May, and at Gensan in July.
