conditions, I have noted a difference of between three and four 

 months in the time of the emergence of the moths — in one instance 

 104 days. But not infrequently, as occasionally in Macrosila quinque- 

 viaculata and other one-

 the earliest larvse complete 

 their transformations dur- 

 ing the same summer, and 

 appear abroad on the wing, 

 but at too late a season 

 for a second brood of larvae 

 to mature and attain pupa- 

 tion. Thus Dr. Harris Fig- 7.— The green grapevine moth, Darapsa Mykon. 

 reports {Entomological Correapondence, page 283), that two matured 

 larvae taken by him on July thirty-first, entered the earth on August 

 third, pupated on August sixth and seventh, and gave out the imago 

 on August twenty-ninth. 



The moth is so well pictured in the figure that it need only be 

 added that the head and thorax are olive-green; the abdomen of a 

 dull green, shaded with reddish; the front-wings greenish-gray, 

 banded and shaded with olive-green; the hind- wings rust-colored, 

 with some green at the internal angle. 



Remedy. 

 The caterpillars of this species have never proved so abundant but 

 that their depredations could be controlled by picking them from the 

 leaves upon which they are feeding and crushing them under foot. 

 In addition to the grapevine, it feeds also on the Virginia creeper, 

 Ampelopsis quinquefolia.
