KEY TO THE FORMS INCLUDED IN THE GENUS ENODL\ 



o\ Male with the fore wings more pointed than those of the female, 

 above with a broad furry band interrupted at the veins and 

 by long triangles in the interstices ; under side of fore wings 

 with post-raedial line irregular, interrupted above vein 6, out- 

 wardly oblique between veins 6 and 4, and usually slightly in- 

 dented on vein 5 ; on hind wings below the fourth ocellus is 



smaller than the fifth creoia (pi. 22, figs. 5, 6) 



a^ Sexes practically alike; under side of fore wings with post- 

 medial line more or less oblique from costa to vein 4, or just 

 above it ; on hind wings below the fourth ocellus is larger 



than tlie fifth portlandia 



6\ Wings beneath with the rows of ocelli edged with white inte- 

 riorly and more or less completely exteriorly ; on the fore 

 wings a white band runs from the costa to the region of 

 the second ocellus, and beyond this a narrower white band 

 runs from the costa to the upper part of the first ocellus ; 

 row of ocelli on imder side of fore wings curved ; second and 

 third ocelli on under side of hind wings with elongate pupils, 

 and fourth usually without a pupil. 



portlandia portlandia (pi. 22, figs. 3, 4) 

 V. No white on wings beneath ; row of ocelli on under side of 

 fore wings below straight; all the ocelli on hind wings 

 below have similar circular pupils. 

 <f. Dark border on hind wings above narrow and tapering 

 anteriorly ; on the hind wings below the dark band be- 

 tween the light line bordering the fourth and fifth spots 

 and the submarginal light line is little, if at all, broader 

 than the distance between the submarginal light line 



and the margin of the wing portlandia anthedon (pi. 22, figs. 1, 2) 



(f. Dark border on hind wings above broader and more uni- 

 form, not narrowing appreciably anteriorly ; on the 

 hind wings below the dark band between the light line 

 bordering the fourth and fifth spots and the submarginal 

 light line is broader, usually much broader, than the 

 distance between the submarginal light line and the edge 

 of the wing; ground color below browner and usually 

 more unifoi-m portlandia borealis 



Although when typically developed the four forms included in the 

 genus Enodia are quite different, three of them are very closely 

 related. On the basis of the available material it appears that typical 

 portlandia intergrades more or less with anthedon, and the latter 

 intergrades with horealis, the relations between the three suggesting 

 the relations between Cereyonis alope pegala, C. a. alope, and G. a, 

 nephele occurring in the same general regions. 



Richards said that creoia intergrades with portlandia. It agrees, 

 however, more closely with anthedon, as is evident from the straight- 

 ness of the row of ocelli on the under side of the fore wings, the 

 absence of clear "white beneath, and the fact that all the ocelli on
