Labial palpi and bead reddish fuscous; thorax dark fuscous, with a reddish 

 shading; abdomen ocbreous; fore wings yellow ochreous with a few scattered 

 black scales, to basal line ; this line is well out from the base, black, broad, with 

 uneven edges, but with generally even, rounded course from costa to inner mar- 

 gin ; narrowly edged with ocbreous outwardly, then wing reddish brown to outer 

 margin ; middle field costally heavily sprinkled with blackish, which is broken 

 by the somewhat large, oval, yellow ocher discal spot ; outer line black, mixed 

 with gray scalfes, not very distinct, parallel with, and near the outer margin. 

 Hind wings shining, light fuscous. 



Fitch says of the larva : " They form cylindrical burrows through 

 the substance on which they feed, lining the sides of the passages 

 with silk ; they grow to be about one-half an inch in length, and are 

 of a cylindrical form, slightly broadest in the middle. They are 

 dull white, the sutures between the segments slightly marked, and 

 not con.stricted. Their heads are hard, hornlike, shining yellow. 

 Thoracic shield is also shining, yellowish white, as is also the anal 

 shield. The surface shows a few scattering hairs, which, on the sides, 

 arise from very faint, smooth, wartlike dots. 



" The pupa is pale yellow, or yellowish white, its sutures marked 

 by fine, slender, chestnut-brown lines, and the eyes prominent, rather 

 large and black. It lies in a slight cocoon formed of snow-white 

 silken threads, through which the pupa is visible." 



The larva live upon meal, flour, and especially upon preserved 

 fruits and jellies of all kinds. It is found everywhere, and may be 

 found almost any time during the Summer.
