black mark on which are the eyelets, and another dusky sj^ot at base on the 

 sides (Fig. 22, a). It webs the leaves together, generallj^ folding a single 

 leaf in two, and living wnthin the fold. Like all true leaf-folders it is very 

 nimble, and wriggles away and drops to the ground Avhen disturbed, while 

 the Skeletonizer makes no especial effort to escape. In feeding, the Leaf- 

 tyer is not confined to the parenchjmia. 



This worm changes to a chrysalis within a fold of the leaf, lined with 

 silk, and when about to give forth the moth, works its way partially out at 

 one end (Fig. 22, d.) The chrysalis (Fig. 22, h) is peculiar from having a 

 rounded projection in front of the head. The moth (Fig. 22, c) is amost 

 unassuming little body Avith the front wings of a dark ash-gray without a 

 shade of an}^ other color, the hind Avings paler. 



In the earl}^ part of the year this species may often be found more 

 numerous than the Skeletonizer, but the latter predominates, so far as my 

 experience goes, in the fall. There is much more to observe yet of its hab- 

 its, and I now merely introduce it and give it a name because of its associ- 

 ation with the preceding species. The same remedies which apply to that 

 will answer for this. 



ToKTRix CixDEKELLA, N. S^i .—Imago (Fig. "22, c) .—Alar expanse exactlj' 1-2 inch. Front wings 

 deey'glossy ash-gray, immaculate. Under a lens they have an irrorate appearance, while in cer 

 tain lights some of the scales appear to form a series of darker transverse sinuous lines. Also scat- 

 tered over the wing may be noticed a dozen or more reddish scales, which are not sufficient, how- 

 ever, to destroy the uniform immaculate appearance. Head, mouth-parts, antennaj, legs, and 

 abdomen of same color. Hind wings paler and semi-ti-ansparent. Fringes of all wings concoloi-ous. 

 Under surface of wings pale nacreous, inclining to pale fulvous around the margins. 



Described from two bred specimens. 



L:n-va (Fig. 22, a) .—Length OSM inch. Form of that of Acrobasis nebula, wrinkled very much in 

 the same manner. Color yellowish-green, the piliferous spots of the same color, but readily dis- 

 tinguished by their polished surface; they are placed in a transverse row on thoracic joints, and on 

 joints 4—12 thei-e are four rhomboidally on dorsum, two laterally on the first fold and one subventral. 

 stigmata between the two lateral spots, and yellowish. Head and cervical shield gamboge-yellow; 

 only a shade darker than body; labrum and two basal joints of antenna3 paler or white, the terminal 

 joint brown; ocelli on a somewhat crescent "shaped black spot (the most conspicuous character) 

 ,a second dusky spot at base of head laterally. Legs immaculate. 



Described from many specimens. 



Pi' pa (Fig. 22, 6).— Length 0.2.5 — 0.30 inch. Brown, characterized by a peculiar rounded projection 

 from front of head; by a little pointed prominence at base of each antennas, and each side of penul- 

 timate abdominal joint ; and by terminating in a broad suppressed piece which produces two decurved 

 hooks. Posterior rim of abdominal joints rasped dorsally, and a slight rasped dorsal ridge near the 

 anterior edge of larger joints. Legs reaching only to end of wing-sheaths. The head-prominence 

 varies in size and slightly in form. 



THE LESSER APPLE LEAF-FOLDER.— Torfr^r wn?«;oranr/, LeBaron. 



(Lepidoptera, TortricidiB.) 



This is the name given to a small pale green worm, by Dr. LeBaron,* 

 who found it doing much damage to the young apple trees in the nursery 

 of Mr. D. B. Wier, of Lacon, 111., in the summer of 1870, but which almost 

 disappeared in 1871. In habit and in size, form and color, it is the exact
