markings, fringe with nine dark bars. Dark markings contrasting and clean-cut 

 on a nearly evenly colored ground, tending to be transverse. 13-15 mm. 



I have not seen this form, and nothing has been published as to its structure. 

 It was taken at Hazelton, Pennsylvania. It is darker than any of a large group 

 of related southern species. 



Pennsylvania; Maryland. 



20. 3ET0M0RPHA Zeller 



(Semiota, Apotomia Dietz) ■ 



Head smoothly scaled, palpi moderate, ascending, flattened, second joint thickened 

 with, scales, and with lateral setae; tongue and maxillary palpi obsolete. Wings 

 ir.ther narrow, ovate-lanceolate. Fore wing (fig. 70) with a more or less hyaline 

 fovea in the accessory cell, which is not wholly separated from the discal cell, the 

 fovea distorting the venation in both sexes; R 3 to R 5 stalked, CUj and Cu 2 united in 

 male, stalked in female. Hind wing with costa sinuate, Sc short. Mj and M 2 stalked, 

 M 3 and CUj united in male, separate in female. iu. 3 and CUi of fore wing stalked 

 in some specimens, in others, free. Fovea with fine spinules on the wing-membrane, 

 which may represent aculese. 



1. S. insectella Fabricius. Dull luteous, dotted with light gray-brown. 8-20 mm. 

 (operosella, inamaenella, ruderella Zeller; multimaculella Chambers, majorella, 

 sigmoidella, transversestrigella, fractilineella Dietz). 



If the species occurs at all in the northeastern States, it is a stray. It is an 

 important pest of stored food in the tropics. 



Family 10. PSYCHID^ 

 (With Tineidffi, in part) 



Mouth parts typically all rudimentary, the palpi usually reduced to 

 hairy tubercles, and the rest lost; a little more developed in Kearfottia. 

 Head with loose, hairy vestiture, that on body variable ; ocelli absent, 

 with rare exceptions. Ej^es small and retracted, often nearly buried 

 in vestiture ; antenna? moderate to very short, in higher forms broadly 

 pectinated, with scaling irregular and confined to the upper side ; in the 

 lower forms with the normal two whorls and some bristles. 



Abdomen of female ending in a bushy tuft, whose hairs are mixed 

 with the eggs. Legs short, and in higher forms, hairy, the spurs tend- 

 irg to disappear. Typically with more or less translucent or transparent 

 wings. Fore wing with base of M quite distinctly preserved and often 

 forked; Cu apparently 2- or 3-branched; accessory cell separated from 

 coll by a fine vein, or fused with it as in other Tineoids, R- 

 always running to outer margin, near apex. At least the middle por- 

 tion of 1st A preserved, often connected to 2d A by a crossvein or 

 running into 2d A; 3d A free at base and quite strong; usually with 

 the tip very distinctly forked, and the upper fork joining 2d A. 

 Hind wing typically with R x full developed, running across to Sc. 

 often with tip of Sc free, and often with an anastomosis between R 

 and Mi farther out; two or three anals, none distinctly forked at
