292 RHOPALOCERA. 



From T. papias the present species differs in having fewer diaphanous subapical 

 spots and in the spot near the middle of the inner margin being quadrate rather than 

 triangular, and diaphanous instead of greenish blue. In T. papias the submarginal 

 blue band of the secondaries both above and below is less broken, and there is no 

 distinct spot lying inside it on the underside. 



A female specimen, taken by Bates at Tunantins on the Upper Amazon, belongs to 

 T. perissographus rather than to T. papias, though somewhat intermediate between 

 the two.

This genus, as now restricted, contains about sixteen species, all of them belonging to 

 the Neotropical region. P. pygmalion and its allies have a close colour-resemblance to 

 several species of Jemadia, which in some cases is so exact that the structure of the 

 antennae alone distinguishes them externally. On the other hand, P. palemon and its 

 immediate relations are more like certain species of Pyrrhopyge, but the resemblance 

 is not so close. • 



Seven species are found within our limits, and are distributed over the whole area 

 from the confines of the United States to Panama. 



The antennae have a stout club ending in a fine sharply pointed hook ; the terminal 

 joint of the palpi is very small, and the end just appears beyond the dense scales of 

 the second joint. The primaries have a costal fold ; the cell is long, exceeding two- 

 thirds of the costa ; the discocellulars are very oblique, the lower discocellular much 

 stronger and longer than the middle and strongly arched ; the third segment of the 

 median is very short, and a recurrent nervure proceeds from its extremity ; the 

 secondaries are elongated, the discocellular meets the median just beyond the origin 

 of its second branch. The tibiae of the hind legs have two pairs of spurs and a well- 

 developed dorsal crest. 



The strongly arched long lower discocellular of the primaries is characteristic of this 

 genus.
