LEPIDOPTERA OF NEW YORK AND NEIGHBORING STATES 161 



OPOSTEGA Zeller 



Eye -cap very large, covering tlie base of the wings, as well as the whole side 

 jf the head, in repose; fore wing caudate, without forked veins. Larvae bast-miners. 



1. 0. albogalleriella Clemens. Silvery white, with a minute black dot at tip 

 of membrane of fore wing; apex of costa somewhat yellowish; two fine, dark lines 

 in costal and dorsal fringes (nonstrigella Chambers, accessoriella Frey and Boll). 



Var. quadristrigella Chambers has a gray shade near middle of inner margin. 



The larva is a bast-miner on gooseberry and red and black currant. The mine 

 often starts in a two-year-old stem and usually ends in it, running up and down 

 the canes, and leaving a scar which is usually visible before the larva leaves the 

 cane, late in June. The cocoon is seed-like and brown. It is spun in the soil, like 

 that of Nepticula. 



Massachusetts to Texas. New York: Otto, Geneva. 



It is possible that quadristrigella is a distinct species; it may feed on 

 Rancunculacese. 



2. 0. cretea Meyrick. White; three lines in costal and two in dorsal fringe; 

 a minute black apical spot; an oblique gray dorsal spot at middle of wing. 8-9 mm. 



Lake Muskoka, Ontario; July and August. 



This species is unknown to me and indistinguishable from its description from 

 0. quadristrigella. 



3. 0. scioterma Meyrick. Fore wing similar to 0. quadristrigella, with an addi- 

 tional gray antemedial band nearly meeting the dorsal one, and a gray border. 

 9 mm. (Unknown to me.) 



June. 



Toronto, Ontario. 



Family 14. GRACILARIID^ 



(Tineidse, in part) 



Vertex either rough or smooth; face of the northern species smooth, 

 at least below; ocelli usually absent; tongue well-developed; labial 

 palpi moderate or long, often upturned, but usually with the third 

 joint set on at a slight angle to the second, and the individual joints 

 not noticeably curved; third joint normally blunt; no bristles. Maxil- 

 lary palpi of porrect type, never folded across the front of the tongue, 

 moderate to rudimentary, sometimes practically absent. Hind tibiae 

 normally smooth-scaled, often with a series of bristles above ; the mid- 

 tibise also bristled in some exotic species. Antennas relatively long, 

 often as long as fore wing, simple, with two full whorls of scales to a 

 segment; eye-cap absent in our species. 



Wings without aculese ; fore wing lanceolate or linear-lanceolate, with 

 lanceolate cell; the accessory cell rarely well-marked; Sc rather short, 

 R x arising before middle of cell, or absent, R 5 running to costa (when 

 recognizable) ; when stalked it is stalked farther with M-L than with 

 R 4 except in Cremastobombycia. The other veins short, and usually 

 running sharply across to margin, part of them lost in the 

 majority of forms. Apex of membrane very often drawn out in a 

 long point, which rarely projects beyond the costal and dorsal fringe 

 (caudate). 1st A a well-marked fold, 2d A simple, often strongly sin-
