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

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

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

 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 forepart 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 raetasternum. 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 wiugs 36 lines. 



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

 length of the hind femora and fore wings; the latter are hardly longer 

 than the hind wings.
