262 CULTURE OF THE GRAPE. 



Another caterpillar of about the same size and habit, 

 producing the Sphinx-nioth Achemon, is more commonly 

 found upon the vine. It is about three inches in length, 

 and the six cream-colored spots on each side are found as 

 in the preceding species ; but they are long and narrow. 

 They have the power of withdrawing the segments of the 

 body within each other (of which there are six besides 

 the head), giving them a blunt appearance. When of full 

 size, they are very voracious, coming to their maturity in 

 August. They then enter the earth, and appear the fol- 

 lowing June as a winged moth, four or five inches from 

 tip to tip of wing, of a light olive, with patches of dark 

 olive color. 



In "The Gardener's Monthly," vol. iv. p. 151, a "new 

 enemy of the grape-vine" is figured and described by 

 Jacob Stauffer, which, he says, was found cutting off entire 

 bunches of native grapes in Lancaster County, Penn., in 

 the month of July, 1861. Mr. Stauffer says this caterpillar 

 belongs to the genus Papilio, which produces a tribe of 

 day-flying, swallow-tailed butterflies. It is styled " a dan- 

 gerous species, undescribed before. It certainly is a fear- 

 \ 

 ful- looking monster." The representation is like the 



Achemon Sphinx caterpillar, with the segments of its 

 body drawn in.
