234 EHOPALOCEEA. 



that species that we have long hesitated to separate it. It may be distinguished, 

 however, by the narrower black border to the secondaries, and by the almost entire 

 absence of the longitudinal ochraceous band which occupies the median portion of the 

 primaries. Mr. Champion's specimens were taken in dense forest near Bugaba, at an 

 altitude of about 1000 feet. He says it is usually a high-flying insect, occasionally 

 descending to the ground, through the openings in the forest, from the tops of the trees. 

 The whole P. zagreus group of Papilio have a general resemblance, both in form and 

 colour, to common species of Lycorea, Melincea, Mechanitis, Heliconius, &c, found in 

 their respective localities. P. zalates has the coloration of Lycorea atergatis, &c, and 

 one of its peculiarities is the blackness of the base of the primaries, so prevalent in 

 representatives of many genera of butterflies in this particular region.

The fold in the secondaries is indefinite in this group, the hairs along its edge being 

 less developed than in the preceding group. The margin of the secondaries is more 

 deeply dentate. The foliate appendage of the front legs is attached to the middle of 

 the joint. The harpes of P. phaeton are narrow, slightly curved rods, the upper and 

 lower edges subparallel ; the distal end is divided into branching points, with smaller 

 dentate processes (see Tab. LXXI. fig. 6). In P. Mrchalli the points are more widely 

 separated, each of them dentate ; the proximal point issues from the upper edge of 

 the harpe, dividing it into two unequal portions, the proximal being three times as 

 long as the distal. In P. Mrchalli and its ally P. xanthopleura the costal margin of 

 the primaries is smooth, whereas in P. eurotas, P. phaeton, Sec. it is distinctly serrate, 

 a character upon which Mr. Butler founded his genus Pyrrhosticta. The females in 

 some members of this group, and perhaps in all, are dimorphic and even polymorphic. 



The species of this group are not very definite, several of them presenting a consi- 

 derable amount of variation. 



The range of the group is restricted to the Tropical parts of South America, its 

 northern limit reaching Southern Mexico, where a single species occurs. In Costa 

 Eica and the adjoining portion of the State of Panama several others are found.
