SPHINX CHERSIS 157 



edge and soon eat as well as any of the brood. Usually 

 they eat small holes through the middle of the upper 

 part of the leaf first, then attack the margin. Holes 

 near the tips of leaves have guided us to many small 

 chersis larvae. 



The moths are large and strong. They are gray, 

 with marks of white and black, especially the black 

 dashes on the fore wings, which give the name of the 

 " pen-marked sphinx " by which the moths are known. 

 The coloring is very clear, and the moths have a clean- 

 cut, elegant appearance. With one exception, ours 

 have not emerged until the following summer. In the 

 very hot summer of 1901 one female moth emerged in 

 August. They fly after dark, and have long tongues, 

 feeding at deep flowers. Their range is wide, covering 

 the country from ocean to ocean, and from Canada to 

 Georgia, according to Mr. Beutenmiiller, who finds 

 them double-brooded near New York.
