LEPIDOPTERA OF NEW YORK AND NEIGHBORING STATES 329 



10. ITHOME Chambers 

 (Eriphia Chambers, in part; not Latreille, Meigen, or Felder) 



Similar to Stagmatophora. Fore wing shorter, short-lanceolate pecten appar- 

 ently present but fugitive. Venation apparently unstable in the number of 

 medials preserved and in degree of stalking of M!. Cu 2 arising near angle of cell. 

 Hind wing with R and Mj long-stalked. 



1. I. unimaculella Chambers. Dark smoky; a small subterminal pale spot on 

 fore wing. Third segment of palpus with a series of pale dots on under side. 

 7 mm. 



This species has been confused with /. (f) concolorella and even with the usually 

 much larger Perimede erransella, but is distinguished by the palpi. 



Southern States; porthern distribution uncertain. 



11. CHRYSOPELEIA Chambers 

 (2E(K,a, Chambers) 



Palpi rather long and slender, somewhat rough, third segment shorter than 

 second. Wings with small tufts; fore wing with Mj long-stalked with R 5 ; M 2 lost; 

 Cu normal; cell central; hind wing linear-lanceolate; Sc obsolete; M t long-stalked 

 with R, which runs to apex; the other veins present, apparently arising from 

 Cu-stem. 



The larva forms a large blotch mine between two veins, starting usually with 

 a tract along the midrib. It forms a frass tube along the midrib, with two walls 

 of frass extending from it to the margin of the leaf. 



This genus is perhaps a reduced Gelechiid, and appears related to Helice. 



1. C. ostryaeella Chambers. Face, palpi, legs, and under side pale hoary gray; 

 vertex, antennae, thorax and fore wings dark powdery steel gray; base of inner 

 margin paler. A paler fascia before the middle, farther out and wider toward 

 inner margin, and a nearly parallel, doubly curved fascia beyond apical third; 

 apex pale, with minute dark tufts in dorsal fringe. Four principal tufts on wing 

 surface, arranged in a diamond, the two basal ones lying along the inner side of 

 the first fascia, and the dorsal one farther out. 6 mm. 



May to August; commoner later. Larva yellowish-white, with brown dorsal 

 spots in front, and a spot on mouth parts; on iron wood (Ostrya) in September. 

 Kentucky; southern Ohio. 



2. C. purpuriella Chambers. Very close to C. ostryceella, the two basal tufts 

 equidistant from base, the antemedial fascia weaker or absent, and the apical one 

 more solidly pale. 6 mm. 



June; end of July. Larva in July and late September; with habits like C. 

 ostryceella, but the mine less regular in form; on red oak. 

 Kentucky. 



12. BLASTODACNA Wocke 



(Mompha, in part) 



Similar to Laverna; pecten present, palpus with second segment a little rough- 

 ened. Fore wing unlike all the preceding genera and like Batrachedra in having 

 the cell squarely truncate ; CUj and Cu, connate from its lower angle. Two large 

 dorsal tufta., 1st A stalked from 2d A. Hind wing with MI and M 2 stalked. 



The larvae are bud-worms and fruit borers on Crataegus and related Rosaceee, 

 and have dense secondary hair besides the usual setae. 



.1. B. curvilineella Chambers. Rather even, powdery, light gray, with two black 

 tufts; sometimes with a dark dash beyond the first, but with no yellow shading.
