tapering on the apical half, bluntly pointed, not stronf^ly curved, ilistaiil from one 

 another hy fully twice the tllametor of one of Ihcm. 



Chrysalis. Very little more tlian twice as long as broail ; the sides of the body 

 from line extremity of the wings to the other straight, or with a Imrely perceptible 

 hollowing next tlic division line between thorax and al)domen, very sliglitly divergent 

 posteriorly, so tliat the body is broadest at the fourth abdominal segment ; here it is 

 somewhat angulated, tlie posterior end tapering at once and forming an elliptical 

 curve, the tip well rounded. In front of tlie wings the body tapers rapidly and has a 

 rounded, scarcely appressed front, the basal wing prominence being marked only by 

 the angle the front part of the body makes with the wings. Viewed from the side 

 the flat bottom is uniform throughout; the posterior third of the thorax is very nearly 

 equal, bnt .slopes forwards a very little, its hindmost extremity a very little the most 

 elevated, roundly angulated in tlie middle of tlie posterior two-thirds and sloping in 

 front of it downward anil forward about equally, scarcely curved. Abilomon very 

 broadly arched above, highest and a very little higher tlian tlie thorax at the third 

 segment, beyond the fourth segment with a pretty strong, downward curve, the lower 

 edge of the eighth segment being tlie most posterior point, tlie whole of the ninth 

 segment directed forwards; the downward curve at the posterior is much more rapid 

 than at tlie anterior extremity of the body. Transversely the middle of the thorax is 

 well arched, the sides sloping away from each other at an angle of about 70°, with a 

 scarcely perceptible hollowing, the summit ratiier broadly rounded ; abdomen regu- 

 larly rounded, forming an almost exact semicircle. More than threo-dfths of the 

 tongue exposed. Body covered equally witli a very delicate tracery of sliglitly raised 

 lines crossing each other irregularly, and ou the wings forming elong.ated, irregular, 

 oval cells; at other places there is a little wart at the intersection of the lines; the 

 surface within these cells is not infrequently occupied in part l)y an independent wart 

 of similar size giving rise to a fungiform papilla (86 : 33), tlie basal two-tliirds of the 

 pedicel slender and equal, the apical third rapidly expanding to a wine glass-shaped 

 disk, hollowed above, the horizontal edges of wliich are fringed with fleshy pointed 

 ciliae. Hooklets pretty long and exceedingly slender, the stem equal, straight on 

 basal, slightly curved on apical half, the expanded portion fully four times as broad 

 as the stem, bent strongly over but not at all appressed to the stem, as the upper por- 

 tion of this is curved, transverse, the sides turned backward considerably. 



This genus of Chiysoplianidi belongs to the northern hemisphere and 

 encircles the globe ; one (or perhaps more) species extends across the 

 whole width of the Old World and reaches from its northernmost coasts to 

 at least Lat. 30', and even as far .south as Abyssinia in Africa and northern 

 India in Asia. In Switzerland it is said by Meyer-Diir to be most abun- 

 dant between 1800-2500 feet above the sea ; another — the species with 

 which we are specially concerned — inhabits the New World, spreading also 

 from ocean to ocean, but confined to a much narrower belt, for it has 

 rarely been found north of Lat. 47° and except in mountainous regions 

 seldom far south of Lat. 40°. It is common throughout New England. 



The butterflies of this genus arc of rather a small size ; the fore wings 

 arc somewhat pointed at the apex and the hind wings, having the outer 

 border straighter than usual, present rather a quadrate appearance ; the 

 tip of the lower median nervule is very slightly produced. The upper 

 surface of the fore wings is of a fiery red, the outer border blackish l)rown ; 

 this is reversed on the hind wings, although on these the red border is in-
