After First Moult (twelve hours). — Color 
yellow-brown, mottled darker, with black patch on 
top of 3 and a black cross on 4; patch on 7 and 8 
triangular, stopping on mid-sides on 7 {dr*). 
The 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 
larvm with brown, disposed in obscure oblique 
stripes pointing forward and downward. 
After Third Moult (twelve hours). —Color 
blue-green. 
The patch mostly suppressed ( g , g 2 ). 
The two lateral salmon bands more or less dis¬ 
tinct. 
On 4 is a long ochre-yellow spot, with a deep 
sinus on its posterior side, the sinus purple. (Figs. 
f 3 0 
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). —The 
After first Moult (twelve hours). — Color 
black-brown ; a black medio-dorsal line, slightly 
expanded on 3 and 4 ; the patch not triangular 
but saddle-shaped, broad on each side and reach¬ 
ing nearly to the feet (e 2 ).

On 4 is a sub-oval green-yellow spot, correspond¬ 
ing with so much of the spot on Rutulus as lies be¬ 
low the sinus; no purple. (Figs, h, h 2 .) 
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. (Figs.j,y 2 .) 
spot on 4 variable in shape, but always elongated; 
the inner extremities .06 inch apart. (Figs, i 2 3 .) 
Rutulus inhabits the country west 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., Bond. 
XIX. p. 276, is a mention of Turnus, on Vancouver’s Island, and it is stated that

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-
