off and burn them, the "Wood Nymphs may be more 

 easily subdued by scattering a few corn-cobs under the 

 vines in the summer — to be raked up and burned in the 

 winter. It has been suggested that many of these moths 

 might be destroyed by exposing poisoned molasses or 

 syrup at the time of their appearance in spring. White 

 HoUebore as described under Currant and Gooseberry 

 would no doubt be efficacious, and good results may be 

 expected to follow the use of Pyrethrum, or Persian In- 

 sect Powder. 



THE GRAPE LEAF-FOLDER. 



{Desmia maculalis, West.) 



This has long been known to depredate on the leaves 

 of the Grape-vine in many widely separated parts of 

 Xorth America. It is not uncommon in Canada West, 

 and is found in the extreme southern parts of Georgia. 

 It appears to be far more injurious, however, in the in- 

 termediate country, or between latitude thirty-five and 

 forty degrees, than in any other sections, and in South- 

 ern Illinois and Central Missouri proves more or less in- 

 jurious every year. It belongs to the same family as 

 our notorious Clover-worm, which attacks our clover 

 stacks and mows. 



This genus is characterized by the elbowed or knotted 

 appearance of the male antennae, in contrast with the 

 smooth, thread-like female antennee; the maxillary palpi 

 are not visible, while the compressed and feathery labial 

 palpi are recurved against the eyes, and reach almost to 

 their summit; the body extends beyond the hind wings. 

 The moth of the Grape Leaf-folder is a very pretty little 

 thing, expanding on an average almost an inch, with a 

 length of body of about one-third of an inch. It is con- 

 spicuously marked, and the sexes differ sufficiently to 

 have given rise to two names, the female having been
