colored spot near the bind angle, and a larger spot of the same 

 color inclosing a black dot just before the tails. It expands one

 Boisd. et Lee. pi. 31. 



Form and size of T. falacer. Upper side clear brown ; on the 

 disk of the primaries a fulvous, oblong spot, transversely disposed 

 and mingling more or less with the ground color. In the female? 

 this fulvous space is preceded by a small black spot. 



Secondaries terminated by two tails, of which the internal is the 

 longer. Between these tails, usually a fulvous spot in the female. 

 In both sexes, there is a small black spot at the base of each tail, 

 separated from the fringe by a whitish or bluish ray. The anal 



spatule is also marked by a blackish spot surmounted with a little 

 . - 



white. .' 



Under side pale ash-gray- primaries traversed by four white 

 lines, more or less distinct, M&lflpnitmg towards the lower edge. 

 Between these lines and the outer edge there is another sinuous 

 white line. Secondaries traversed by two double rays, of which 

 the anterior form a sharp angle below. Behind these rays, there 

 is a fulvous macular band, formed of from three to six spots, bor- 

 dered slightly with black. Anal spatule is marked with a little 

 black, and between it and the long tail there is a bluish space. 



Under side of the body like the wings. Breast, abdomen below, 

 and feet grayish-white. Antenna black, with white rings ; club 

 tipped with fulvous. 



Larva yellowish-green, with a dorsal line and eight oblique 

 streaks of dark green. Marginal ray green, yellow below. 



1 There is an almost inextricable confusion in the determination of these 

 species. T. humulus Harr. has been mistaken for T. favonius Sm. Abb., 

 but is different. Boisd. has figured this species as F. favonius in Boisd. et 

 Lee. pi. 30, but he is doubtful himself of its correctness. He says, " I am 

 by no means certain that Abbot's Favonius is the same as the one I give. 



After having carefully examined my specimens and attentively 



compared them with the original drawings and notes of Abbot, I have 

 come to the conclusion that my Ifyperici is the same as my Favonius .... 

 and that T. liparops is the true Favonius."
