It is very well represented in the accompany-ing illustration in its different stages of growth, hence will notbe described in detail. Like others of the web-worms, thisspecies conceals itself in a web when not feeding, and in whichit retreats during daytime. This web is well illustrated in at b. Dr. J. A. Lintuer, in his first report as entomologist ofthe state of New York, in speakiug of the family characteristicsof this insect says (p. 139): To those who are not familiarwith that division of the pyralid moths to which this species be-longs—the Cramhidce—it may be of interest to state that they.
