In addition to the plants above mentioned, this leaf-roller has 

 been found by Packard upon the pine, and by others upon the lo- 

 cust, grape, strawberry, cotton, and orange. Mr. Coquillett bred it 

 from Verbena hastata, Dr. Kellicott from Ranunculus acris, Mr. Walsh 

 from grass and willow. We have bred it this summer from the 

 following list of plants besides corn : common burdock {Lappa 

 major), red clover. Verbena icrtlcifoUa Monarda fistulosa, and Erlgeron 

 canadeuse. Although its injuries have not been reported serious, its 

 wide distribution, its abundant food resources, and the number of 

 successive broods, bring it within the list of species capable of 

 serious mischief under favoring circumstances. 



NATURAL ENEMIES. 



Prof. Comstock says, "One of the larva; on clover was found to 

 be infested with a hymenopterous parasite, which, however, failed 

 to emerge." 



In our own breeding cages three hymenopterous parasites emerged 

 this summer, all true Ichneumonidse. 



3. The Eed-Banded Leaf Pioller. 

 {Lophoderus trifcranus, Walk.) 



Order Lepidoptera. Family 'Tortricid^. 



This species occurs somewhat rarely in Illinois, and has not been 

 reported throughout its wide range to do any injury except to the 

 cranberry in Massachusetts, where its larva is locally known as one 

 of the cranberry worms. We bred it, however, during this past 

 season, from pale green leaf rollers in young corn, and consequently 

 may regard it as worthy of brief mention, especially as its local 

 abundance in cranberry plantations in Massachusetts would indicate 

 a capacity for excessive multiplication which makes it a possible 

 source of danger in the great corn fields of the Mississippi Valley. 



The presence of this larva and of that of the sulphur leaf roller 

 just treated, is mdicated in corn fields by the folding lengthwise or 

 rolling of the leaves in May and June. If these leaves be opened, 

 a green wriggling larva will be found enclosed in a web within. 



The moth hatching from these folded leaves in June, if Lop)hoderus 

 triferanus, may be recognized as an insignificant brown species, 

 about a half inch across the spread wings. The fore wings are 

 reddish brown except on the terminal fourth which is gray speckled 

 with black, as is also the basal half of the posterior edge of the 

 same wings. 



A more detailed description is given beyond. 



The species w^as first described by Walker in 1863, as Caca'cia 

 triferana, and again by Clemens in 1865, in the proceedings of the 

 Entomological Society of Philadelphia, under the name of Tortrix 

 incertana. A better description of the moth, with figures of male
