them were almost full fed ; they became more abundant by 

 the middle of the month. A slight cocoon is formed in the 

 flower from the debris loosely held together with silk, and 

 from this the brown pupa pushes its way out some hours be- 

 fore the emergence of the moth. Of those under observation, 

 the first appeared May twenty-third, though at that date many 

 of the later larvae had not pupated. The latest emergence 

 noted was June thirteenth. 



From unripe ovaries of Sarracenia pur pur ca gathered near 

 Katahdin Iron Works, Maine, later in the season (August), 

 the same insect was bred, and Mr. Kearfott identifies it as 

 Olethreutes dacckeana, a species which he described in 1907 

 from a New Jersey locality where its food-plant was also 

 Sarracenia purpurca, so it is evidently widely distributed and 

 will probably be found wherever Sarracenia is abundant. 



Archips parallela Rob. 



Toward the end of May still another insect may be found 

 attacking Sarracenia minor; this is the larva of a Tortricid, 

 a smooth, cylindrical caterpillar about seven-eighths of an 

 inch in length, dull dark sage-green in color, studded with 

 small white tubercles bearing short fine white hairs ; the head 

 and thoracic shield are yellowish-brown with black markings, 



and the feet black. 



This caterpillar seems to prefer the smaller open leaves of 

 Sarracenia minor. It fills the upper portion of the tube with 

 a white opaque web, through which it retreats in a tortuous 

 passage when alarmed. In feeding it takes no care not to 

 eat entirely through the leaf-wall, and the upper portion of 

 the hood usually shows a ragged hole where the caterpillar 

 has fed. A number of these larvre of different ages were 

 found in localities widely separated, so their occurrence in 

 this food-plant was evidently not accidental. Of these, one 

 fell a victim to the new leaf to which it was transferred, 

 evidence that this insect has not yet perfectly adapted itself 

 to this dangerous food-plant. One larva on June third left 

 the leaf in which it had been feeding, ensconced itself on the
