PAPILIO I. 
four anterior segments and dorsally throughout, crossed by a pale yellow and four 
grey stripes. This phase continues to maturity, about four days. Among 66 larvae 
of Walshii there was remarkable uniformity, and especially none were green, nor 
was there a trace of the blue band on fourth segment which replaces the white one 
in many larvae of Telamonides and Marcellus. Duration of larval state from 22 to 
29 days. 
Chrysalis .8 to .9 in length, greatest diameter .3; cylindrical, tapering pos- 
teriorly from middle of abdomen ; head triangular, terminated by two short, lateral 
sub-conic points; another on thorax, triangular, the upper edge slightly curved, 
beak-like; from this two small ridges pass along the wing cases and down the ab- 
domen to extremity, and between them two others starting from upper segments of 
the abdomen, on the outer sides of which last, in those chrysalids which are brown, 
is a fine dentaied light colored line; surface reticulated and on the abdomen 
marked more or less distinctly by transverse abbreviated dark bars; color either 
dead leaf brown or bright green. Duration of chrysalis state 14 days, but with fre- 
quent cases of irregularity. Some of the chrysalids retain the imago till the follow- 
ing spring.
