PAPILIO XII., XIII. 



After First Moult (twelve hours). — Color After first Moult (twelve liours). — Color 

 yellow-brown, mottled darker, with black patch on black-browu ; a black medic-dorsal Hue, slightly 

 top of 3 and a black cross on 4 ; patch ou 7 and 8 expanded on 3 and 4 ; the patch not triangular 



triangular, stopping on mid-sides on 7 (rf'*). 



Tlie stripe below sub-dorsals distinct (as in first 

 stage). 



No lilac spots on dorsum in the early part of 

 this stage ; but at three days from moult appear a 

 pair on 9, 10, 11 each. 



After Second Moult (twelve hours). — 

 Color either bright green (no brown) ; or green, 

 mottled and specked over dorsum with olive- 

 brown ; or olive-brown, mottled in darker shades 

 and no green. 



The patch salmon-red, triangular. 



A salmon stripe along edge of dorsum and an- 

 other low on side, both the length of body. 



The sides specked with light green, in the brown 

 larv;B with brown, disposed in obscure oblique 

 stripes pointing forward and downward. 



After Third Moult (twelve hours). — Color 

 blue-green. 



The patch mostly suppressed (g, ff'^). 



The two lateral salmon bauds more or less dis- 

 tinct. 



Ou 4 is a long ochre-yellow spot, with a deep 

 sinus on its posterior side, the sinus purple. (Figs. 



The distance between the inner extremities of 

 the two spots across dorsum is .04 inch, none over 

 .05 inch. 



Color green from the moult. 



After Fourth Moult (twelve hours). — Tlie 

 spot on 4 variable in shape, but always elongated ; 

 the inner extremities .06 incii apart. (Figs, i" ^.) 



Rutulus inhabits the country we.st of the Rocky Mountains to the Pacific ; is 

 seen more or less in those mountains in Colorado and Arizona. How far to the 

 north, in British Columbia, it flies, I am unable to say. In Ent. M. Mag., Lond. 

 XIX. p. 276, is a mention of Turnus, on Vancouver's Island, and it is stated that 

 its eggs are laid on willows. This was a mistake for Rutulus, of course ; Turnus 

 certainly not flying west of the main divide, and its larvae not feeding on willow. 

 Throughout California, Rutulus is common, and Mr. W. G. Wright, of San Ber- 



but saddle-shaped, broad ou each side and reach- 

 ing nearly to the feet (e"). 

 No stripe. 



Many lilac spots from the beginning, two on 4 

 inside the sub-dorsal tubercles, two on 5, 10, 11. 

 (Fig. e.) 



After Second Moult (twelve hours). — 

 Color black-brown, mottled with lighter. 



Patch yellow-white, saddle-shaped as before. 



No stripes. 



No such markings. 



After Third Moult (twelve hours). — Color 

 usually olive-brown ; sometimes dull green on an- 

 terior segments ; brown after S. 



The patch distinct. 



No bands. 



On 4 is a sub-oval green-yellow spot, correspond- 

 ing with so much of the spot on Hulnlus as lies be- 

 low the sinus; no purple. (Figs. /;, //^.) 



The distance between the inner extremities is 

 .12 to .15 inch. 



At two days from the moult gradually loses the 

 brown, but in many cases never wholly. 



After Fourth Moult (twelve hours). — The 

 spot on 4 sub-oval or pyriform ; the inner extrem- 

 ities .16 to .18 inch apart. {^^S^-j\j^-)
