margin (like a Bucculatrix ?), and an apical ocellus. The larva is pale 

 livid reddish (unlike any known Lithocollctis larva, but not unlike some 

 Gracillarice). It feeds on leaves of Apple and Pear trees between two 

 leaves, or in a fold of a leaf. (This is very unlike a L/thocolletis.) 



8. L. curvilineatdla Packard. This larva is unknown. The pupa was 

 found in a long slender cocoon, attached to the bark of an apple tree. 

 (This is like a Bucculatrix, but not like a Lithocollctis). The imago is 

 pale whitish with yellowish scales, with an apical ocellus in the wings, and 

 a roundish spot on the middle of the dorsal margin. (Like a Bucculatrix). 



.9. L. nidificansella Pack, is said to be silvery white with an apical 

 ocellus ; three oblique golden costal streaks, and spotted with gold below 

 the costa. The pupa is suspended in a thin web. outside of the leaf 

 between its edges, which are drawn towards each other. This is very 

 different from the habit of a Lithocollctis pupa. 



The two species of Dr. Fitch, these three (?) of Dr. Packard, the seven- 

 teen species of Dr. Clemens, and the fifteen species which I have de- 

 cribed in these papers, make the total number of described American 

 species of Lithocollctis up to this time, thirty-seven. 



L. trit(?ucaudla, ante p. no, is scarcely sufficiently characterized to 

 distinguish it from the European L. trifasciclla as described and figured 

 by Stainton, Nat. His. Tin. v. 2. As compared with Stainton's figure, this 

 species is more golden, the fasciae are straighter, with much narrower dark 

 margins, and in this species the only dark dusting is a small spot at the 

 apex. Still, if there is much variation, this may be the same species. In 

 Trans. Loud. Ent. Soc, Sec. 2, 7'. 2, is a figure of trifasciclla not nearly so 

 well executed as Stainton's, but more nearly resembling this species. It, 

 however, has a dorso-apical patch of dusting, which is wanting in this 

 species. 



What do Mr. Stainton, Dr. Clemens and others, mean by " the spring 

 brood" and "the fall brood,*' &c, of Lit/iocollctis and allied genera ? 1 

 confess I do not know. I know what it means when applied to some 

 insects, because, as to such, there is "a time for all things'* — a time when 

 they are found only in the larval state, a time when they are found only in 

 the pupal state, and a time when only the imago can be found. Indeed 

 this seems to be the case with most moths, even with the Micros. For 

 instance, many (not all) species of Gracillaria are found as moths, only in 

 the fall, or in the spring and fall, and the larva only is found at midsum- 

 mer. But in the genera, Lithocollctis. Phyllocnistis, Tischeria. Cefniostoma,
