ulata, Haworth. (Lepidoptera. Sphingidse.) Plate 4, fig.l. 
Eating the leaves of potatos, tomatos, and tobacco, in July and August, a largo green 
worm the size of onojs finger, with a black horn at the end of its back and along each side a 
row of seven white or pale yellow marks resembling the letter < with its pointed end forward; 
lying underground in its pupa state during the winter and spring and producing a largo gray 
moth, four and a half inches wide across its extended wings, having a row of fivo yellow spots 
along each side of its body and two narrow black zigzag bands across the middlo of its hind 
wings. 
Hon. William Kelly, in a letter enclosing to me one of the millers 
which had been obtained from the tobacco-worm by Charles L. Roberts, 
Esq., of TariflVille, Ct., well remarks that the culture of tobacco has 
become so important an interest now at the North, that any information in 
regard to its insect enemies will be read with interest. Mr. Roberts 
alludes to this tobacco-worm as being quite prevalent in his vicinity. 
And the pains which some other correspondents and friends engaged in 
the culture of tobacco have taken to transmit specimens of the worm or 
the miller to me is an evidence of the importance they attach to this 
insect. And it may well be regarded as an important enemy; for this 
tobacco-worm makes the growing of tobacco twice as laborious a task as 
it would be if we had no such insect in our country. 
This is currently supposed to be a new insect here at the North, unlike 
anything which we previously had, and that its presence here is due to 
the extensive growing of tobacco which has recently been commenced. 
It, however, is the same worm which, from time immemorial, we have 
been accustomed to meet with in midsummer upon our potato vines, and
