482 LEPIDOPTERA. 



resemble the European PentJdna comitana,* and perhaps 

 may be merely a variety of it. The head and thorax are 

 dark ash-colored. The fore wintrs 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 marks 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 crca- 

 tures 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 withered 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 dis- 

 covered. 



Apricot, peach, and plum trees, when trained against 

 walls in the open air, are said to suffer very much some- 

 times 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, I cannot say whether they 

 are of the same species as the bud-moth above named.
