both sexes a little dusky outwardly. Beneath whitish, with the usual 

 outer line and discal spot. 



Expanse, 1.25 to 1.46 inches (33 to 37 mm.). 



Hahitat. — Canada to Florida, west to the Pacific coast; Mississippi; 

 Colorado; Portland, Oregon, in May; Central Kew York in May; 

 Georgia in April; Massachusetts in June. 



This species is easily recognized by its very dark colors, the almost 

 total absence of the transverse markings, and the narrowly strigate 

 character of the ornamentati(m as a whole. The wings seem to be 

 almost subequal and are only a little oblique on the outer margin, so 

 that the creature seems narrower winged than its immediate allies. 

 The front is convex and a little protuberant. The palpi are well 

 developed, are free from the front and reach to fully its middle. The 

 harpes of the male are slender, rounded at tip. The clasper is dis- 

 tinct, stout. The upper process is heavy, only a little curved, and of 

 moderate length. The finger-like process from the upper margin is 

 slender and almost straight. Twenty specimens of both sexes have 

 been under examination. 



LARVA. 

 Edwards and Elliot, Papilio, 1883, III, p. 132. 



Egg. — Flattened, like two-thirds of a sphere, with about forty-eight 

 ribs, diminishing in number above, not confluent; smooth, a wavy line 

 on the apex and in the hollows. Micropyle finely reticulate. 



Stage I. — Whitish, translucent; the food green. Purplish dorsal 

 patches on joints 5, 8, 9, and faint on 12. Dorsal setae, I-III, black, 

 lateral, IV-V, white, all single, no subprimaries, skin smooth. Head, 

 0.3 mm. wide. 



Stage II. — Head whitish; width, 0.45 mm.; slight brown streaks in 

 the angle of the lobe. Body nearly colorless, green from the food, a 

 purplish-brown patch covering warts I and II on joints 5, 8, 9,- and 12 

 and trace of a white subdorsal line in dashes over warts I and II on 

 the pale segments. Dorsal hairs blackish, lateral pale. Warts with 

 long setae, two from wart I, and clusters of short secondary hairs with 

 slightly bulbous tips, concolorous with the marks. Later a white sub- 

 dorsal line is more distinct, shajjed in outline of the markings of the 

 mature larva. 



Stage III. — Head, 0.8 mm. wide, bilobed,the lobes pointed; whitish, 

 with a brown shade below the apex of each ; shining. Body green from 

 the food, otherwise nearly colorless ; a white subdorsal line touching 

 each segment, most distinct on joints 7-10, where it borders a faint 

 brown patch dorsally on joints 8 and 9. A slight tint of brown also 

 on joints 5 and 12. .Hairs long and dark, sparse, with many slender, 

 short, finely bulbous-tipped pale ones spreading slightly on the skin 

 as secondary hairs, only a few dark even in the dark marks. 



Stage IV. — Much as in the next stage, the marks fainter; dorsal
