LEPIDOPTERA OF NEW YORK AND NEIGHBORING STATES 97 



(5) N. anguinella Clemens, Proc. Ent. Soc. Phila., vol. 1, p. 85, 18(51; Tin. 

 No. Am., 17"). 1872. " May be found in the leaves of oaks early in 

 October and in the latter part of June. The mine is a very narrow 

 serpentine tract, irhieh is filled or discolored throughout its length 

 by blackish excrement. The larva fits the mine closely, in color lemon- 

 yellow, with ten square dark brown or blackish spots on the ventral 

 surface." 



It should be possible to recognize this species, when found, from Clemens' 

 description of the larva. 



(G) N. platea Clemens, Proc. Ent. Soc. Pliua., vol. 1, p. 85, 1861; Tin. No. Am., 

 175, 1872. "Mines oaks early in October. The mine is a. moderately 

 broad, winding tract, with a broad line of dispersed grains of excre- 

 ment. The larva is purplish, with a pale green vascular line and a 

 row of reddish-brown dorsal dashes, ihe mine is much broader than 

 that of the preceding miner." 



The statement that the larva is purple cannot be regarded as conclusive, 

 since such color is often produced in larvae feeding on leaves with 

 autumnal coloration. 

 Quercus alba, white oak: 



(7) 2V. quercipulchella; long, narrow, winding and gradually widening track; 



larva bright green. 

 Quercus palustris, pin oak: 



(8) N. similella; linear mine, expanding into an underside blotch, followed 



by a large, conspicuous, nearly transparent blotch; larva pale green. 



(9) 2V 7 . altella; lower-side, very long, serpentine mine, not distinctly "visible; 



larva yellow with row of dark brown dashes. 



(10) E. heinrichi; flattened-oval, spiral mine in bark of young branches. 

 Ulmus spp., elms: 



(1) N. apicialbella ; narrow, serpentine mine. 



(2) N. ulmella; narrow, linear track, enlarging into an irregular blotch. 

 Platanus occidentals, sycamore : 



(1) N. platanella; narrow, linear mine, abruptly enlarging into a large blotch. 



(2) N. clemensella ; linear mine, gradually broadening with terminal portion 



expanded into a small blotch. 

 Physocarpus opulifolius, Opulaster : 



(1) N. opulifoliella ; brownish, contorted, serpentine mine. 

 Pyrus communis, pear : 



(1) A T . chalybeia; serpentine mine. 

 Pyrus mains, apple: 



(1) ft. pomivorella; serpentine mine, usually broadening to 2 or 2.5 mm. 

 Amelanchier canadensis, service berry: 



(i) N. amelanchierella Clemens, Proc. Ent. Sec. Phila., vol. 1, p. 84, 1861; 

 Tin. No. Am., 174, 1872. " In the leaves of service-berry or June- 

 berry, Amelanchier canadensis, in June and July. The mine rather a 

 broad tract, sometimes much contorted, with rather irregular edges, 

 placed most often towards the base of the leaf and having a rather 

 broad " frass " line of a dark brown color." 

 This species seems to be distributed wherever its food plant occurs; 



mines observed in Ohio, Kentucky, North Carolina. 

 Crattegus spp., hawapple : 



(1) N. cratcegifoliella; serpentine mine, with a breadth of about 2 mm. at 



the end. 



(2) IV. scintillans : contorted, serpentine mine, scarcely exceeding 1 mm. in 



breadth.
