LEPIDOPTERA. 3l9 



> skin on the top of the eighth ring. They generally come to 

 their growth by the middle of June, and are changed to shining 

 brown chrysalids within the curled leaves, in a little web of silk, 

 wherewith their retreats are lined. The chrysalis has only one 

 row of prickles across the rings of the back. The moths come 

 out early in July. They very closely resemble the European 

 Penthina comitana*, and perhaps may be merely a variety of it. 

 The head and thorax are dark ash-colored. The fore-wings are 

 of the same color at each end, and grayish white in the middle, 

 mottled with dark gray ; there are two small eye-like spots on 

 each of them ; one near the tip, consisting of four little black 

 marks, placed close together in a row, on a light brown ground, 

 the inner ma#ks being longer than the others ; the second eye- 

 spot is near the inner hind angle, and is formed by three minute 

 black spots, arranged in a triangle, in the middle of which there 

 is sometimes a black dot. The hind-wings are dusky brown. 

 This moth expands from one half to six tenths of an inch. It 

 may be called Penthina oculana, the eye-spotted Penthina. My 

 attention was called to the depredations of this bud-moth, and of 

 the preceding species, by John Owen, Esq., of Cambridge, by 

 whom the moths were raised from the caterpillars, and presented 

 to me. It is difficult at first to conceive how such insignificant 

 creatures can occasion so much mischief as they are found to do. 

 This seems to arise from the number of the insects, and their 

 mode of attack, whereby the opening foliage is checked in its 

 growth, or nipped in the bud. To pull off and crush the wither- 

 ed clusters of leaves containing the caterpillars or the chrysalids, 

 is the only remedy that occurs to me. It were to be wished 

 that some better way of putting a stop to the ravages of the leaf- 

 rollers and bud-moths, that infest many of our fruit-trees and 

 flowering shrubs, could be discovered. 



Apricot, peach, and plum trees, when trained against walls in 

 the open air, are said to suffer very much sometimes from the 

 attacks of insects whose habits resemble those of the eye-spotted 

 Penthina. But, as I have not yet seen them in the moth state,
