Larva nearly an inch long ; stout and cylindrical ; bead 

 small and horny, shining chestnut-brown, with the mouth 

 blackish ; second segment, which is rather long, tapering 

 rapidly forward, yellowish-brown ; skin most delicately 

 shagreened, bone-white with the undersurface whiter ; there 

 is, however, a blackish tinge over the anterior and posterior 

 segments; dorsal vessel distinguishable by its darker tint; 

 raised dots small and indistinct, surrounded by small 

 depressions, and furnished each with a short brown hair ; 

 spiracles small, round, and margined with black ; anal plate 

 yellowish-brown ; legs tipped with chestnut-brown ; prolegs 

 whitish with the circlet of hooks dark brown. (Rev.

August or September till May, on flour, corn, maize, bran, 

 and meal, and among refuse of these substances, living in 

 long tubes of silk placed along boarding, or any wall or 

 other solid substance in contact with the food : apparently 

 attacking only stored food indoors — not corn when growing, 

 nor even in the ricks. 



Pupa very cylindrical and plump, the wing-cases reaching 

 only one-half its length ; the tail ending in a blunt knob, 

 without a spike, but furnished with a group of six curled- 

 topped spines, arranged in three pairs of different lengths, 

 the largest pair being straight and the other two curved ; 

 skin glossy as though varnished ; wing-cases j-ellowish- 

 brown ; the abdomen more red, and the segmental divisions 

 still darker ; in a closely fitting cocoon of tough white silk, 

 well covered on the outside with rubbish. (Rev. J. 

 Hellins.
