 (Champion), Veraguas, Calobre (Arce). — Easteen Peeu ; Cuba ; Haiti. 



Though Mr. Bates described this Terias as distinct from T. gundlachia, from 

 specimens obtained by us in the interior of Guatemala, there can be little doubt 

 that the Cuban and Central-American insects belong to one and the same species. 

 We have only one Antillean specimen before us, a female from San Domingo, and this 

 agrees accurately with examples from the mainland. 



We have now a large series of specimens from many parts of Mexico and Central 

 America, showing that the species has a wide range within our borders, and that it 

 is found in the mountains at elevations varying from near the sea-level to a height 

 of 6000 feet. 



Some variation exists in the angular projection of the secondaries, which is always 

 more prominent in the females, and in the males it is more produced in some specimens 

 than in others. 



b'. Subcostal branch of secondaries emitted beyond the cell. (Sphcenogona, Butler.)

We apply this name to the Terias figured by Boisduval and Geyer, both of which 

 represent the male, though Boisduval's description is based upon two species, his 

 so-called male being Terias boisduvaliana, Felder, his supposed female the male of 

 the present insect. This initial error has given rise to great confusion, Dr. Felder 

 renamed the male T. boisduvaliana, and left the so-called female to stand as T. mexi- 

 cana, as it had previously been called by Geyer. Unfortunately he further confused 

 matters by describing the true female of T. mexicana as T. damaris. In his Lepi-
