wings pellucid; veins pule green; apical patch green. Length of the bod) 

 10 lines ; expansion of the fore wings 35 lines. 



It nearly agrees with O. Mexicanus in the comparative length of the 

 hind femora arid the fore wings, but is larger and has two white stripes on 

 the prothorax. The acute keels of the prothorax distinguish it flora 

 O. Huastecus.

Male. Green, smooth, shining, rather stout. Head as broad as the 

 prothorax; vertex very broad and not keeled between the antennae, where 

 there is a short white longitudinal streak ; front between the eyes as broad 

 as the fore part of the vertex, with which it is closely joined ; labrum white. 

 Eyes prominent, nearly round. Prothorax rugulose ; disk nearly flat, not 

 widening hindward; lateral keels much rounded; fore border undulating ; 

 sides with a conical outline ; hind border slightly rounded. Mesosternum 

 more deeply excavated than the metasternum. Cerci curved, very pilose, 

 nearly cylindrical. Styles short, lanceolate. Legs slender; spines minute; 

 hind femora about half the length of the fore wings. Fore wings fusiform, 

 rather broad, minutely reticulated, with numerous whitish points ; large 

 areolets not apparent, except towards the base and along the costa ; branches 

 of the externo-medial vein much curved. Hind wings pellucid ; veins 

 white; apical patch green. Length of the body 10^ lines ; expansion of 

 the fore wings 36 lines. 



It agrees with O. Otomius, salicifolia and Totonacus in the comparative
