This species varies considerably in coloration, especially in the tint of the underside 
of the wings, some specimens being dull brown, others of a rich rusty red. The 
secondaries; too, of many specimens have a very distinct ferruginous margin; but in 
others this passes into the general colour of the rest of the wings, a series showing a 
complete transition from one to the other. The rufous margin, however, is more 
commonly seen in specimens from northern localities. 
We are not quite sure that the insect called 7. chrysogone in Messrs. Butler and 
Druce’s list of Costa-Rica butterflies? is rightly referred to this species ; but as we cannot 
trace any specimen of the true 7. chrysogone in Dr. Van Patten’s collection, and as we 
find a single specimen of 7’. virgilia having the rufous margin to the secondaries already 
spoken of, which, to a much greater extent, is present in 7. chrysogone, we think it 
probable that this name was inadvertently applied to the Costa-Rica butterfly. 
It is not always very easy to distinguish this species from 7. andromeda. In Central 
America the presence in the secondaries of a well-defined subanal spot in the latter is 
one distinguishing character; and the greater straightness and better definition of the 
inner of the two transverse lines also helps in their differentiation. In South America 
these points of difference are not so apparent.

As Mr. Butler remarks, this species is somewhat intermediate between 7. chelys of 
Brazil and T. virgilia. On the upperside it strongly resembles the former; but the
