PAPILIO I. 



four anterior segments and dorsally throughout, crossed by a jmle yellow and four 

 grey stripes. This phase continues to maturity, about four days. Among 66 larvse 

 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 larvse of Telamonides and 3Iarcelhis. 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 ujiper segments of 

 the abdomen, on the outer sides of which last, in those chrysalids which are brown, 

 is a fine dentated 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.
