EURYBIA. 377 
b'. Secondaries suffused with blue. 
3. Eurybia unxia, sp. n. 
E. salome et E. upis affinis, sed posticis ceruleo lavatis forsan distinguenda. 
© ceruleo inornata. 
Hab. Nicaragua, Chontales (Belt); Costa Rica, Cache (Rogers); Panama, Chiriqui, 
Calobre (Arcé). 
This form of Eurybia is certainly very closely allied to #. upis, Hubner, but seems 
separable by reason of the blue shade which overspreads the secondary wings when 
held in a certain light. It is also distinguished from H. salome by the absence of the 
brick-red colouring of the outer portion of the secondaries. 
Our specimens are chiefly from Costa Rica; those from the State of Panama have the 
blue of a rather more purple hue.

This Eurybia differs from E. lamia in having the blue colour restricted to the 
secondaries, and in general, but not always, in the absence of two white subcostal 
spots on the primaries, always present, so far as we know, in Ei. lamia. 
As will be seen above, E. lycisca has a wide range, and is fairly constant in its 
markings at least in Central America; our Venezuelan and Guiana examples are much 
smaller than usual, though one of our Nicaraguan specimens is about equal to them in 
size. In Nicaragua too there seems to be more variation in colour than elsewhere, for 
in a male specimen in our series, which in other respects seems to be E. lyeisca, the 
characteristic blue of the secondaries is wholly absent, and in a female it is only faintly 
seen. These can hardly belong to another species; for the present, at least, we treat 
them as aberrations from the normal type. 
Our specimen from Quirigua was captured in the forest where the wonderful Indian 
ruins stand, not far from the bank of the Motagua river. Mr. Champion’s specimens 
were taken in dense undergrowth.
