1911] Ilypcra and Phytoiwinus in America 421 



Oregon: Am. Mus. Nat. Hist. 1. 



Washington: "W. T." two in Horn coll. (Am. Ent. Soc). 



The specimens reported by Dejean and Schonherr were 

 given as from "America boreal." Probably the Say specimen 

 of com plus was from the Mississippi valley region, though his 

 statement "United States" would lead one to believe that he 

 had specimens from a number of places. 



Food Plants and Life History: Riley (1881) reports breeding 

 this species from "Polygonum nodosum." Dr. Smith bred it 

 from a species of Polygonum in New Jersey. I have seen 

 specimens from Columbus, Ohio, (Osborn), with the cocoon 

 still attached to a leaf that appeared to be Polygonum. Through 

 the kindness of Dr. S. A. Forbes I have permission to use some 

 notes made by me while connected with the State Entomologist's 

 office several years ago. 



In October, 1902, I found several species of larvae feeding 

 on leaves and flowers of a Polygonum (identified for me by 

 Dr. Gleason as probably P. hartwrightii) on the Hartwell 

 ranch near Pegrim, 111. At that time the country was flooded 

 with water, only the top of the plants being above the water. 

 The larvae were almost full grown and some were already in the 

 cocoons, others had changed to pupae. The cocoons were made 

 on the upper side of the leaves, the edge being bent over to aid 

 in concealment. I bred a number of adults and some parasitic 

 Hymenoptera. Dr. Forbes very kindly loaned me this material 

 and from it Mr. J. C. Crawford of the U. S. Nat. Museum has 

 described - — . The parasitic pupae of this species 



were naked, jet black and formed in the cocoon of the host. 



In Biol. Cent. Am. Coleop. v. 4, pt. 4, p. 2, this species is 

 incorrectly referred to as probably a synonym of P. rumicis.
