Type in U. S. Nat. Mus. Coll. (No. 15,075). 



The specific name is derived from an ancient tribe of Indians 

 dwelling in Yucatan and the adjoining parts of Guatemala, 

 famous for their high degree of culture and the wonderful 

 structures that they built. 



In the size and wing-coloration, this species suggests certain 

 members of the oblique-fasciata group, {oblique-fasciata Mcqt.; 

 craven Bell.), but differs notably in venational- and leg-charac- 

 ters. In general color it resembles the next species, fumipennis, 

 of Peru. 



The venation is very like Ilolorusia Loew, and it is quite 

 possible that maya may prove to belong to this genus. It is 

 much smaller than rubiginosa Loew, which has the wings more 

 uniform, dorsal thoracic stripes not clear, petiole of cell M, 

 short, etc.

 of the mesopleurae dark brown, except a very broad, conspicuous, yel- 

 low band running across the dorsal portions of the pleuraj from the
