Genus Papilio 



sis, is represented in Plate XLIV, Fig. 2, by a male specimen. It 

 is characterized by the great breadth and intensity of the black 

 bands on the upper side of the wings, which are quite as broad 

 as in the summer form marcellus. 1 find this form prevalent in 

 the spring of the year on the St. Johns River, in Florida. Ex- 

 panse, 2.50-2.7=5 inches. 



{b) Winter form telamonides, Felder, Plate XLIV, Fig. i, 3. 

 In this form the tails of the hind wings are somewhat longer 

 than in walshi, and are not simply tipped, but bordered on either 

 side for half their length with white, and the red spots near the 

 anal angle do not coalesce to' form a crimson bar, but are sepa- 

 rate. The black transverse bands on the upper side are wider 

 than in walsht. Expanse, 2.75-3.00 inches. 



(c) Summer form marcellus, Boisduval, Plate XLIV, Fig. 

 3, 3 . In this form, which represents the second generation emerg- 

 ing in the summer and fall from chrysalids produced from eggs 

 of walsbi, flon'densis, and telamonides, the tails of the hind wings 

 are greatly lengthened, being fully twice as long as in ivalsbi, the 

 black bands are greatly widened, and there is but a single small 

 spot of crimson (sometimes none) above the anal angle of the 

 secondaries. Expanse, 3.00-3.25 inches. 



Early Stages. — These are well known. The caterpillar feeds 

 on the leaves of the papaw {Asimina triloba), and wherever 

 this plant is found the butterfly is generally common. 



Ajax ranges from southern New England, where it is very 

 rare, west and south over the entire country to the foot-hills of 

 the Rocky Mountains. It is very common in the lower Appa- 

 lachian region, and in southern Ohio, Indiana, Kentucky, and 

 Tennessee is especially abundant. 



(2) Papilio eurymedon, Boisduval, Plate XLIV, Fig. 5, 5 

 (Eurymedon). 



Butterfly. — This beautiful insect belongs to the same group 

 as the four succeeding species. In the style of the markings it 

 recalls P. titrmts, but the ground-color is always pale whitish- 

 yellow or white, the tails of the hind wings are more slender, 

 and the white marginal spots on the under side of the fore wings 

 are fused together, forming a continuous band. There are other 

 differences, but these, with the help of the plate, will suffice for 

 the ready identification of the species. Expanse, 3.50-4.00 

 inches.
