slight depression in the center of each. The color of the egg is 

 dull yellowish pink" (Saunders). 



Young Larva. — " Length about one fifteenth of an inch, cylin- 

 drical. Head large and black, with a few black and brown hairs. 

 Body above of a dull shining yellow, with a wide dorsal band of 

 dull white. On each segment there are from eight to twelve shining 

 black dots, from each of which arises a single black or brown hair. 

 The upper portions of second and terminal segments have each a 

 large patch of black. Under surface similar to the upper, but with 

 fewer dots; feet black; prolegs pale greenish, faintly tipped with 

 brown" (Saunders). 



Full-Grozvn Larva. — '' Cylindrical, tapering slightly at each end 

 and one inch in length, when crawling elongating itself to 1.15, and 

 0.18 thick. It is clothed with fine, shortish, scattered hairs which 

 are placed symmetrically. Its ground color is pale green, of a yel- 

 lowish or apple green tint when full grown, but usually pea green 

 when it is smaller. Along the middle of its back is a stripe of a 

 deeper grass green color, and a similar one upon each side of the 

 back. These three stripes extend from the neck to the middle of 

 the penultimate segment. Each of the lateral stripes has a dull 

 cherry red spot at its anterior end, placed on each side of the middle 

 of the neck or first ring, and in rare instances the anterior ends of 

 these lateral stripes are of this color for a short distance. Before it 

 is full grown the lateral stripes are sometilnes faint or wholly want- 

 ing; and low down on each side is an elevated fold of the .skin 

 which forms a faint stripe of a paler color than the ground. The 

 head is a third narrower than the neck and is held obliquely down- 

 ward and forward. It is slightly paler than the body and is clothed 

 with fine erect hairs. 



"A variety of the larva occurs, of a dull pale brownish yellow 

 color, with the stripe olive or dull brownish green. In one instance 

 a young larva 0.60 long was observed wholly destitute of the red 

 spots upon the neck" (Fitch).
