Costa Rican Clothilda would, a priori, very probably 

 differ from the more northern species. We find that it 

 does,, and that the specimen does not represent the 

 normal female of 0. euryale. As shown before, the 

 species of this genus have no apparent tendency to vary; 

 I have, therefore, though at present only a single speci- 

 men has reached us, no further hesitation in considering 

 that it belongs to a representative of the Mexican species, 

 and is distinguishable by well-marked characters. 



These differences consist in the presence of a well- 

 marked band on the hind wings, and in the absence of 

 the red spots seen in G. euryale on the same wings; 

 beneath, the ochi-aceous colouring is bright, and instead 

 of being brownish and the light markings forming a 

 band beyond the cell, are very much larger, and more 

 clearly defined; the margin of the hind wing is not so 

 deeply sinuate, and the curvature of the outer margin of 

 the anterior wing not so deeply concave.

This species is quite distinct from the preceding. It 

 differs in being smaller in size, in having the costa of 

 the anterior wings less abruptly arched, and in being 

 destitute of the brilliant red spots on the upper surface 

 of the same wings, which have only a reddish tinge at 

 the base ; beneath, the markings are very indistinct com- 

 pared with those of G. euryale. 



This species seems to be very rare. Our specimen 

 formed part of Mr. Tweedie^s collection.
