yellow, the pur})lish markings conjointly forming an X, usually quite 

 distinct. 



From the records of about twenty-seven rearings and a large number 

 of dates for the adult, the species seems to be imperfectly three-brooded 

 in Illinois. In the District of Columbia it is three-brooded, according 

 to Comstock, in Michigan two-brooded (Cook), and in Maine probably 

 single-brooded (Fernald), as also in Minnesota, judging from Lugger's 

 statements. Davis's supposition that it winters as a pupa is apparently 

 wrong, as its first records for the season are all of the larval stage. Very 

 probably it winters as a larva, as Comstock suggests. The first brood 

 of moths in the District of Columbia and New Jersey appears in the 

 latter part of May and early June; in Illinois, from June 10 to the begin- 

 ning of July; still later in Michigan (Cook); and in Minnesota in July 

 (Lugger). The second brood comes about a month and a half later; 

 in Illinois, from late July to the beginning of September. In Michigan, 

 larvae of this brood probably hibernate, but in Illinois a part, at least, 

 reach the imago stage in late September and early October, as is indi- 

 cated by a slight increase at that time in the number of imagos present 

 at lights. In the District of Columbia there seems to be a full third 

 brood of adults in September. The larvae with us are found from the 

 middle of May until after the middle of June; the second brood, in July 

 and the first part of August. A single larva taken early in September, 

 which became an adult September 17, probably belonged to the third 

 brood. 



The Red-banded Leaf-roller. 



Eulia triferana Walk. 

 (Lophoderus triferanus.) 



This is another wide-spread leaf-roller which includes the corn plant 

 among its diversified food resources. It has lately caused a very unusual 

 and severe injury to green pop-corn in New York by infesting the ear and 

 destroying the kernels. Over a fourth of the crop was involved, and 

 about three eighths of the corn on the infested ears was destroyed. 



This species is found from Maine to New Jersey and west to Missouri, 

 and also in Texas. It has a large and varied list of food plants, including 

 among trees, the apple, oak, elm, soft maple, and 

 Osage orange; among garden crops, beans, asparagus, 

 salsify, and tomato; among field crops, corn, pop- 

 corn, and clover; also raspberry, cranberry, Gnapha- 

 lium pohicevhahirn, rose, chrysanthemum, lobelia, Fk;. itis. TheRe.i-
