LEPIDOPTERA OF NEW YORK AND NEIGHBORING STATES 229 



SUPERFAMILY GELECHIOIDEA 



Vestiture usually scaly even on the head (figs. 147, 148) which never 

 shows the high bristling vestiture of the normal Tineidae; ocelli small 

 or absent ; antennae normally with dorsal surface scaled, with two rows 

 to a segment; the outer row much longer than the other and often 

 encircling the antenna. Ventral surface bristled, the bristles very long 

 in some Blastobasida; and CEcophoridfe. Antennas pectinate in some 

 exotic forms (see Ptochoryctis). Palpi almost always upturned beyond 

 middle of front, the third segment long and pointed, regularly tapering 

 for most of its length (unlike the fusiform segment of most Tineoidea 

 and Tortricoidea) ; second joint frequently with a tuft, which is usu- 

 ally less ragged than in the Tortricidae; never bristled; third seg- 

 ment rarely tufted. Palpi rarely reduced (Pigritia group; fig. 179). 

 Tongue usually moderate, scaled at base ; maxillary palpi, when present, 

 characteristic, minute, but of folded type, and curving over base of 

 tongue; absent in forms with much reduced mouth parts. Epiphysis 

 large. Palpi and tarsi never bristled or spined; hind tibiae rarely 

 bristled, but almost always hairy. 



The legs are not displayed as in the Heliodinidae, and habits of dis- 

 play are less common than in that family and the Glyphipterygidae, 

 but are shown, for instance, by Stomopteryx agrimoniella. 



Wings highly variable in form and venation; but the fore wing 

 always with an ample cell, frequently w r ith a well-marked accessory 

 cell imperfectly set off from it. R 5 often running to the outer margin, 

 but only in primitive forms with broad wings, R 4 also terminating 

 in the outer margin in a few exotic Xylorictidw; 1st A commonly 

 lost (in the whole large family Gelechiidae) ; 2d A more or less forked 

 at base. Hind wing variable, normally oval, but also trapezoidal, or 

 even bifurcated in the Gelechiidae, narrowing in other forms till it is 

 linear in some Cosmopterygidas ; 1st A varying as in the fore wing, 

 and 3d A also often vanishing with it ; 2d A forked as usual. Costa 

 often sinuate and often bearing a tuft of bristles two-fifths way out. 

 R t frequently distinct, becoming free in a couple of the most reduced 

 genera. Base of M obsolete in both wings. Female frenulum of 

 few (normally two or three) bristles. 



The egg is of the flat type and is laid externally: so, far as I know, 

 always singly. The larva (fig. 150) always has three setae on the 

 prespiracular wart, and a single subventral on the meso- and meta- 

 thorax, and the prothoracic spiracle normal. On the abdomen, setae 

 iv and v are closely approximated, i and ii separated and usually 

 at nearly the same level; on the ninth abdominal segment, ii is not
