168 EHOPALOCEEA. 



The dusky basal half of the costa of the primaries renders this species easy of 

 recognition. The sexes as determined by Mr. Bates are almost exactly alike. 



This species appears to be rather scarce in our region ; we have as yet seen only a 

 single specimen from Nicaragua and three from the State of Panama. 



Mr. Kirby has placed T. mana as a simple synonym of T. agave of Cramer, thereby 

 following Boisduval himself, who cites Cramer's plate as applicable to his T. mana ; but 

 the description shows discrepancies which are hardly reconcilable. In the first place 

 the black border of the secondaries in the figure of T. agave extends round the anal 

 angle instead of stopping short of it, and there is a much wider dark border to the 

 secondaries . than in any specimen before us. Under these circumstances we think it 

 best to use the name T. mana for this species. 



We figure a male from the Isthmus of Panama.

 (F. D. 6r.),Valladolid in Yucatan (Gaumer); British Honduras, Corosal (Boe). 



We have described and figured specimens taken at Orizaba in March 1888. They 

 do not quite correspond with typical T. jucunda from Florida, being of rather a paler 

 yellow, and the outer border of the secondaries is not quite so definite. Beneath they 

 almost exactly correspond, the males having a yellow wash over the discal area of the 

 primaries, and the secondaries are silky white, with a few dark scattered scales. 

 Compared with T. sidonia, which has also yellow secondaries, T. jucunda differs in 

 its less definite border to those wings, and by the absence of yellow on the primaries 

 beneath ; moreover, the female of T. sidonia is hardly tinged with yellow, and has all 

 the lighter margins of the wings obscured by numerous dark scales. 



T. jucunda appears to be wholly an eastern insect, and in Mexico is confined to the 

 shores of the gulf, extending southward to British Honduras.
