outside of another leaf of minor in the angle formed by the 

 flat wing of the leaf and the outside of the tube, and here 

 spun a tubular shelter by bridging this corner with a web of 

 opaque white silk; here, a few days later, it changed to a 

 brown pupa, which on June twenty-second forced its way out 

 of the cocoon by means of the double row of spines with which 

 its segments are armed, and the moth emerged. Mr. W. D. 

 Kearfott pronounces the moth to be a typical specimen of 

 Archips parallela Rob., a widely distributed species with a long 

 list of recorded food-plants. On some of its other food-plants 

 this caterpillar spins several leaves together to form a more 

 or less tubular shelter. It would be interesting to determine 

 to what extent it is adapting itself to the other species of 

 Sarraccnia found within its range. 



POLLINATION. 



That Sarracenia must depend upon insect agency to effect 

 pollination of the blossom was recognized long ago by the 

 botanists, and the structure of the flower indicates something 

 of the method by which this must be accomplished. Careful 

 observation of the insect visitors of Sarracenia ftava through- 

 out its blooming season make it seem probable that in this spe- 

 cies the method of pollination differs in some respects from 

 the published accounts of this process in the genus Sarracenia 

 in general. In flava, as in the other species of the genus, the 

 style is a curious umbrella-shaped structure, each of its five 

 points being cleft, and the stigmatic surfaces are situated on 

 little projecting points at the base of these clefts on the con- 

 cave side of the open umbrella. The petals at the base form 

 a close bell-shaped cover, spreading out and filling the space 

 between the points of the inverted umbrella ; and access to 

 the nectar and pollen is possible only at one of five openings, 

 situated just below the curled-up tips of the umbrella with 

 their projecting stigmatic .points. 



An insect alighting on a petal enters the flower, turns at 

 right angles in either direction to one of these openings, and 

 in forcing its way through, if of suitable size, scrapes its back
