October 27, 28. and 31. 1919. Miss Marion T. Van Horn collected 

 this leaf-roller in war gardens at Potomac Park in the District of 

 Columbia on sweet potato and on lima and other beans. The leaf- 

 rollers were found in particular abundance where sweet potato and 

 bean vines grew together. Half a dozen or more larva? were fre- 

 quently found in a hill, while many rolled and webbed leaves proved 

 that the larvae had been quite plentiful earlier in the season. 



It was noted that toward the end of October and the early days of 

 Xovember the larva? rolled the leaves from the sides and from the 

 ends, making a more substantial shelter than when they were imma- 

 ture, and lined it with white silk preparatory to pupation. 



The fact is noteworthy that this species was more numerous on 

 sweet potato and beans in 1919 than in previous years, the first being 

 an unrecorded food plant. In former years this species has some- 

 times occurred in raspberry quite as abundantly as the strawberry 

 leaf-roller (Anci/Jis comptana Froehl.). 



DESCRIPTIVE. 



THE MOTH. 



The moth which produces the red-banded leaf-roller is a small, 

 mottled brown form with the fore-wings having an expanse of be- 

 tween a little more than half to nearly three-fourths of an inch 

 (13 to 19 mm.). The pattern of the fore-wings varies to a consider- 

 able extent. In the female there is a large, median, dark reddish- 

 brown band running obliquely from the middle of the costa to the 

 tornus. a subapical. irregular, smaller one. and a third postero-basai 

 patch of the same color. The lighter parts of the wings are pale 

 reddish brown, arranged in irregular bands with borders of pale 

 yellow and silver white. The hind-wings are infuscated. with wide 

 wnite borders and an inner ciliary line. The abdomen is dark gray 

 and the tufts of the head and thorax are reddish brown. 



The females are usually considerably larger than the males, with 

 rather more distinct and larger patterns. 



The female moth is shown in figure 1 with expanded wings at a, 

 and in natural position, when at rest with the wings folded, at l>.
