22. ENCHRYSA Zeller 



Similar to Aristotelia, but with the outer half of the costa distinctly concave. 

 Palpi entirely smooth, as long as head and thorax, and strongly divergent. 



1. E. dissectella Zeller. Dark bronzy brown, nearly black. Basal half of fore 

 wing brown with decided green iridescence, the brown area ending in a vertical 

 yellow line. Outer half orange, with a large blackish patch, starting just beyond 

 middle of costa over half as wide as the wing, and gradually tapering to apex. 

 Fringes blackish. Apical fourth of antenna white. 11 mm. (Aristotelia youngella 

 Kearfott). 



July. Eare. 



Ontario to Ohio, west to Vancouver Island. New York: Wells (New York State 

 Museum ) . 



23. CHRYSOPORA Clemens 



(Aristotelia, in part; Nannodia Heinemann; Nomia Clemens, not 



Latreille) 



Very close to Aristotelia. Palpus hardly longer than head, with third segment 

 much shorter than second. Fore wing as in Aristotelia; hind wing narrow (fig. 

 168) with apex strongly produced, and Mj rudimentary. 



1. C. lingulacella Clemens. Golden yellow; head and thorax blackish, iridescent; 

 palpi paler with fuscous third segment; antennae dark. A blackish, more or 

 less metallic, patch on base of costa; an elongate one on basal half of inner 

 margin, and a large trapezodial patch on middle of costa, all edged with brilliant 

 violet-silver. Costa edge brown outwardly. Fringe dark brown, with silver in its 

 base below apex. Hind wing dark. 7 mm. (hermanella Chambers, armeniella 

 Frey and Boll ) . 



May; August. Caterpillar in September, in a large blotch-mine on Chenopodium 

 and Atriplex. 



Pennsylvania and Kentucky to Michigan and Kansas. 



2. C. hermanella Fabricius. Very similar, but with the silvery antemedial band 

 extending clear across the wing, and the ground deeper orange. Caterpillar like 

 lingulacella,. 



Ontario; Minnesota; Iowa; Missouri; possibly introduced from Europe. New 

 York: Ithaca. 



24. RECURVARIA Haworth 



(Restricted, not Meyrick. Evagora Clemens; Eidothoa, Sinoe Cham- 

 bers; Aphanaula Meyrick) 



Palpi slightly roughened beneath, third segment nearly as long as second. Fore 

 wing (fig. 167) with Mj stalked with R 5 nearly to apex, CUj longer than Cu 2 and 

 much more closely approximated to M 3 ; usually with raised scale-tufts. Hind 

 wing typically nearly trapezoidal, male often with costal hair-pencil. R and MI 

 only moderately approximate at base. 



The catrpillars of one group are miners in the needles of various conifers. In 

 the needle-conifers they pass from needle to needle in a thin silken tube along the 

 stem; in the scale-type they eat out the spray as a whole. The moths emerge in 

 June. The young larvae hatch in July and form a minute mine in a single needle 

 in which they hibernate, in the spring moving to a new place and feeding up 

 rapidly. The deciduous feeders live in a silken tube on the suface of the leaf, 

 and seem to have the same seasonal history. The species are close and not fully 

 understood; many can hardly be determined without the food plant.-
