other portions of Northern South America several closely allied forms are found, and 

 P. iphidamas itself occurs in the neighbourhood of Santa Marta. 



P. iphidamas is one of the commonest species throughout our country. It has not 

 yet reached us from the forest region of the Mexican State of Vera Cruz, and we have 

 only a single female example from Teapa, and but few from Yucatan and British 

 Honduras. It abounds in the low-lying forest lands of Vera Paz, but is scarce in 

 similar country bordering on the Pacific. From Guatemala to the State of Panama it 

 is probably found in all suitable localities up to an elevation of 2000 to 3000 feet. 



Mr. Reakirt includes P. echelus of Hiibner in his list of Mr. O. Zcettling's collection 

 from Nicaragua 10 ; this must either be a wrong determination or a wrong locality, 

 perhaps the present species should have been referred to.

A single male specimen submitted to us by Dr. Staudinger agrees very well with 

 Felder's figure of P. alyattes and the specimens sent us by him under that name. It 

 is very closely allied to the forms of P. iphidamas in which the light spot on the 

 primaries is small and the olive-green spot spreads towards the inner margin. The red 

 band of the secondaries is situated just beyond the cell, and is thus farther removed 

 from the outer margin than is the case in P. iphidamas.

This species is a close ally of P. iphidamas ; the most obvious difference is the absence 

 of the whitish spot in the primaries ; the red spot, too, on the secondaries seems to be 

 usually smaller, and, so far as we can see, is seldom carried into the apical angle as in 

 many instances in the allied form. The name P. erithalion was based upon female 

 specimens stated to have come from Colombia and Jamaica 1 , but the latter locality is 

 doubtless erroneous. P. pyrochles of Doubleday came from Colombia 4 , and was
