232 TAWNY-STRIPED AND BLACK HEADED PALMER WORMS. 



the winged moth it crowds itself partly out from between them, 

 in which situation the empty shell remains after the moth has 

 evacuated it. At the upper left-hand corner of the figure the 

 relics of the pupa are represented, protruding in this manner 

 from between the leaves. 



The larva when full grown is half an inch long and about 0.0G in diameter, 

 composed of thirteen segments, distinctly marked by strong wide contractions 

 at each of the sutures. The last segment is divided into two parts by a su- 

 ture across its middle. The body is slightly flattened and of a pale tawny 

 yellow color above, with two stripes upon the back and one along each side 

 of a white or yellowish white color. Below the lateral white stripe the body 

 on the sides and beneath is pale watery yellowish. Upon the back the edges 

 of the segments are j^ellowish white, and on the hind part of each, outside of 

 the white dorsal stripes is a polished black dot, from which arises a fine hair. 

 A few other hairs are scattered symmetrically over the surface, arising from 

 small faint dots. The head is flattened, slightly shining and of a paler yellow 

 color than the body, with the antennae and the tips of the feelers dusky. The 

 neck has five or six dark brown dots each side, irregularly placed and some of 

 them slightly confluent. 



The moth is very similar to that of the common species, from which it may 

 be distinguished, however, by its fore wings being destitute of any black or 

 darker colored atoms. They are ash-gray and glossy, often with a purplish 

 red reflection, with a row of equidistant black dots on the apical edge at the 

 base of the fringe. Forward of the tips is a dull tawny yellow band margined 

 on its anterior side with dull white. Two dots behind and two forward of the 

 middle, placed as they are in the common species, are also of a dull tawny 

 yellow color margined anteriorly with dull white, sometimes these dots are 

 confluent, forming two short oblique stripes. The expanded wings measure 

 0.65. 



The common Palmer worm is so variable both in the larva and 

 the perfect stages of its life, that I am not without suspicions 

 this may be merely a variety of that species. But as it is later 

 in the season in making its appearance in each instance where I 

 have met with it, and is differently marked in its larva as well 

 as its perfect state, I am induced to regard it as a distinct spe- 

 cies. 



Associated with the Palmer worms on apple and also on forest 



trees are found worms which are in all respects like them, ex- 

 cept that the head and the upper side of the neck or second seg- 

 ment is black and highly polished, the neck having a slender 

 whitish line on the middle. Though I have not succeeded in 

 breeding any of these it is quite probable they are the progeny 

 of a moth which may occasionall > be met with in company with 

 that of the Palmer worm, and which I named C. contubemalellus
