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. SETOMORPHA Zcllcr 

 (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 

 rather narrow, ovate-lanceolate. Fore wing (fig. 79) 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 

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

 M 3 and Cu, united in male, separate in female. ii 3 and Cilj 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, inamosnella, 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. PSYCHIDJE 



(With TineidsE, 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. Eyes small and retracted, often nearly buried 

 in vestiture; antennae 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- 

 ing 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 

 cell by a fine vein, or fused with it as in other Tineoids, R 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 1 full developed, running across to Sc, 

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

 and 1^ farther out; two or three anals, none distinctly forked at
