mer these larva? extend their burrows through the root-stock?, 

 throwing up new turrets from time to time as they follow the 

 winding course of the interlaced roots. Pupation takes place 

 in a wide part of the burrow, not far from the surface, pro- 

 vision having previously been made for the escape of the moth 

 (middle figure, Plate VIII). The first pupa was noted Sep- 

 tember twenty-second, though some not observed were evi- 

 dently a few clays earlier: the moths commenced to emerge 

 October sixteenth, the last emergence of eighteen beinsr Xo-

vember third. 



The unusually long larval period is presumably the effect 

 of the long season in this southern locality, the insect being 

 single-brooded here as in the north. 



Mr. Henry Bird has described this larva from specimens 

 found in Sarraccnia purpurca in Xew Jersey (see Can. Ent. 

 xxxv, 91-94), in which plant they did not pupate in the bur- 

 rows, nor was the turret-building habit observed. Mr. Bird 

 has kindly compared the South Carolina specimens from flava 

 with his Xew Jersey specimens from pnrpurca, and finds them 

 identical, the examples bred from flava, as would be expected, 

 being slightly larger.

The larva of E.ryra rolandiana has been noted as feeding 

 V in the flowers and unripe ovaries of Sarraccnia purpurea. 

 At Summerville no E.vyra larvae were found in the flowers 

 of either Sarraccnia flava or Sarraccnia minor. The flowers 

 of minor, however, which begin to appear toward the end of 

 April, are frequently destroyed by a small Tortrix caterpillar, 

 which feeds among the petals and stamens and also burrows 

 into and hollows out the green ovary, fastening the debris 

 of the flower together with silk. In these larva-infested flow- 

 ers the umbrella-shaped style withers and the shrivelled petals 

 cling to the wreck of the flower instead of falling at the usual 

 time. The lower figures on Plate VIII illustrate a healthy 

 flower after the fall of the petals and an infested one. 



These larva? were noted about May first, when a few of
