rown, sprinkled with minute cream-colored or straw-colored 
pots. There is a cream-colored line along the back, and a yellow 
ne along the sides, connecting the spiracles, or breathing pores, 
diich appear like black points, each one being surrounded by a 
arrow white ring. The perfect insect is a dark brown or black- 
ih moth, varied with rather obscure whitish spots and zigzag 
nes. The hind wings are dark coppery-red, with a dusky bor¬ 
er. The larva is figured in the American Entomologist, Yol. I., 
age 225, and the moth in Yol. II., p. 26. 
I received some of these Caterpillars from Mr. E. J. Ayers, of 
r illa .Ridge, early in May, with the following note : “ The green 
forms with cream-colored spots, I find on my grape vines. They 
re not numerous, but they are ravenous feeders. Should they 
ecome numerous they would be very destructive.” At the time 
t their reception the leaves of my cultivated grape vines were 
ut just opening, and I fed them on the leaves of the wild grape 
ine which was running over my garden fence and which was 
lore advanced. They are, as Mr. Ayers remarks, gross feeders, 
nd are very easily reared. Some caterpillars are very restless in 
Dnfinement, but these creatures strongly remind me of a hog, 
eing perfectly contented so long as they had enough to eat. 
ometimes, after eating their fill, they would roll over upon their 
ides and take a rest, very much like the gluttonous animal just 
Bt'erred to. 
They began to transform on the 16th of May, folding a piece 
f grape leaf pretty close around their bodies, and lining the 
avity very slightly with silk. Different individuals remained in 
ae chrysalis state from forty-two to forty-eight days. The char- 
cter of the moth is strongly contrasted with that of the larva with 
aspect to its activity. The caterpillar, as we have just stated, 
i gluttonous and sluggish in its habits. The moth, on the con- 
•ary, is extremely alert, and rapid in its motions, lying in an ab- 
apt, zigzag manner. I came very near losing some of my 
oecimens, though they were within the walls of my office. One 
f them flew precipitately across the room, dove in amongst the 
ooks in one of my cases, and concealed itself so artfully and per- 
naciously, that though I saw where it flew, I had to take down 
pwards of an hundred volumes before,! could discover it. 
This insect has also been bred by Mr. Riley, of St. Louis, and
