Walker described specimens of this and the following species together 

 under the same name in 1873, Bergroth separated this as a distinct 

 species in 1887. The species certainly show a marked difference both 

 in size, color and sculpture. 



Palawan, Iwahig, P. I., (11733 C. M. ^Yc'bcr), 6 specimens.

This is a very easily recognized species, owing to its shining surface. 

 This is its first record for the Philippines. It is quite abundant at 

 Iwahig.
