 Cockerell, Ann. & Mag. Nat. Hist. (1914), VIII, 13, 430. 



Luzon, Laguna, Los Baiios {Baker 1790) ; Mount Maquiling 

 {Baker 7453) . Only males have been received. Smith described 

 the species from a male from the Philippine Islands. According 

 to Meade-Waldo, the insect described by Cameron (1905) from 

 Borneo as M. varidens is identical with M. laticeps.
