tropical South America; we have, however, no trustworthy record of it in our country 
to the north of Nicaragua, where both Belt and Janson met with it. Doubleday, 
however, gives it from Honduras with doubt, a statement requiring confirmation. The 
older authors received their specimens from Surinam! 2, where, according to Madam 
Merian, the caterpillar feeds on the fruit of the pine. Mr. Bates speaks of it as a 
conspicuous object in all semicultivated places near settlements on the banks of the 
Amazons 4.

Colenis, Section I., Doubleday, Gen. Diurn. Lep. p. 143. 
In Colenis, as here restricted, we continue to associate C. julia and its allies, which 
must be regarded as the typical species of the genus, and C. ph@rusa, an aberrant form 
so far as regards the characters of the secondary sexual male organs. In C. julia the 
harpagones are unilobed, the distal margin being rounded and without hooks or 
prominences. In C. pherusa they are bilobed, the upper lobes being two distinct 
decurved hooks, the lower lobes being blunt. Regarding the structure of the front 
legs of the males no material differences are to be traced: the femur, tibia, and tarsus 
are all slender; and the tarsus is about half the length of the tibia instead of one third 
as in Metamorpha dido. The subcostal branch of the primaries is thrown off beyond 
the cell in C. julia, instead of before it as in M. dido. Should it prove necessary to 
separate C. pherusa from C. julia and its allies, Hiibner’s name Pantoporia may be 
used for the former. 
Colenis is also a tropical American genus just reaching Texas, and well represented 
in the larger Antilles by races allied to C. julia. About eight species are known.
