and it takes more than a superficial examination to detect a differ- 

 ence in the larvae. These are known as blue caterpillars. They have 

 four to six transverse black stripes on each segment, resemble some- 

 what the larvae of the Sphingida?, in fact they were included in this 

 group by the older entomologists. Now they are placed in the small 

 group Zyganida?. Grape leaf crumpler, Desmia maculata, is a 

 great pest in the vinery. With me it has been more numerous in 

 the cold grapery. They sew together grape leaves and have the 

 general habits of the leaf eating Tortricidte. The larva? are pale 

 green, marked with transverse wrinkles. 



Petrofora diver silineata. A rather handsome geometer that has 

 given me much trouble not only with my hardy grapes but particu- 

 larly in the cold grapery — under glass. The larva? when at rest 

 during the day, stand stretched up at about the same angle of the 

 branches and leaves; this together with the fact that in color and 

 general appearance they closely resemble the branch or leaf on 

 which they are fixed, makes an experienced as well as sharp eye 

 necessary to detect them. I fear this insect is likely to prove a 

 great pest in this state. 



The arctias is represented by Arctia Isabella. The larva? of the 

 arctia are called hedge-hog caterpillars. They are entirely covered 

 with bunches of rather stiff hairs. These hairs are black, for one- 

 fourth at each end, and bay in the middle of the body. They 

 feed mostly on herbaceous plants, but frequently ascend grape 

 vines and make themselves at home to our cost. 



The Virgin moth, SpMosoma Virginica. The larva of this moth is 

 known as the yellow bear. They are a general feeder but have a 

 partiality for the grape. They appear to like the warm sunshine of 

 the cold grapery. They deposit their eggs on the under side of the 

 leaves, and in a few days a host of little hairy caterpillars are feed- 

 ing as if their lives depended on making good time. 



Drapsia Miron. This species of sphinx, one of our worst enemies, 

 selects the grape as the food plant for their young. The larva? have 

 a well defined caudal horn. 



Thyrens Abottii is also a grape feeder. The larva has an eye-like 

 spot on the rump in place of the usual horn of most of the Sphyngida?. 



Philampelius pandorus and P. achemon usually prefer the 

 ampelopsis, but by no means despise the grape. I have known 

 them to strip a grape vine of its leaves in a few days. They can
