 THE FULL-GROWN LARVA. 



When full grown the larva of this species bears some resemblance 

 to that of the Indian-meal moth (Plodia inter punctella) . It is, how- 

 ever, considerably smaller and more slender, and is 

 somewhat flattened by comparison. It may be de-

"V\Tien fully extended it is about eight times as long as wide. 

 Head quite narrow, in contour nearly identical with that of 

 Plodia; of the same pale brown color, with sutures well marked, 

 and appendages and mouth-parts still darker. Thoracic plate 

 nearly one-third wider than head, well divided at middle-; light 

 brown dorsally and dark brown at sides. Thorax and dorsum 

 sparsely covered with concolorous piliferous tubercles with incon- 

 spicuous hairs. Body entirely pale carneous or pinkish; lower 

 surface showing slight carneous tint in first two thoracic joints and 

 Anal plate quite small, about the same color as the head. Legs
