We have described and figured a pair taken together at Zapote in Western Guatemala 

 by Mr. Champion. The male agrees closely with one of the types of T. lydia now before 

 us, differing only in having the dark band parallel to the inner border of the primaries 

 rather wider ; but narrow banded specimens occur throughout our region, so that we do 

 not attach much value to this difference. In its typical form the secondaries beneath 

 are nearly pure white ; but there is a good deal of variation, especially amongst the 

 females, in this respect, some specimens of that sex from the interior of Guatemala are 

 completely overcast with greenish-dusky scales. The typical form has the secondaries 

 nearly evenly bordered with dusky black. This character, however, varies to such an 

 extent that the border is sometimes almost confined to an apical spot ; and when this is 

 the case the individual resembles T. persistens or T. rhodia, but may then be dis- 

 tinguished by the pale and not rufescent under surface of the wings. Whether T. lydia 

 is really distinguishable from T. palmira of Poey is, we think, an open question. The 

 males are exceedingly alike ; but as the females of the latter species are rather whiter 

 at the base of the costa, and are more rufescent beneath, we are reluctant to unite 

 the island and mainland forms. 



Messrs. Butler and Druce referred a male from Van Patten's collection to T. palmira, 

 and a female to T. eugenia of Wallengren ; we have, however, just stated our reasons 

 for not considering T. palmira identical with T. lydia, and as to T. eugenia we are in 

 considerable doubt as to what it refers. Mr. Butler has usually referred it to a Central- 

 American or Antillean habitat ; but the type is said to have come from the island of 

 San Jose, which we take to be the island of that name in the Gulf of California. We 

 have nothing at all resembling T. lydia from this region, so that we hesitate to accept 

 Mr. Butler's identification of T. eugenia.
