ANNUAL REPORT OF NEW-YORK 
GRAPE. LEAVES. 
127 . Gartered plu.mk, Pleropharusperiscelidactylus, Fitch. (Lepidoptera. 
Alucitidae. j 
Consuming the young leaves, in June, and hiding itself in a 
hollow ball made of one or more leaves drawn together by silken 
threads; a cylindrical pale green worm, nearly half an inch long, 
with rows of white elevated dots sending out radiating white 
hairs, the pupa suspended by its tail and hanging with its head 
downwards, and in about a week giving out the moth, early in 
July. The moth tawny yellow, its wings split into long narrow 
lobes, the fore pair with three white spots and beyond these two 
white bands, the fringe white with a blackish spot on the middle 
and another on the apex of the inner margin. See Transactions, 
1854 p. 843. 
4. Insects eating the leaves. 
128 . Grape-vine flea-beetle, Ilaltica chalybea, Illigcr. (Cotcoptora. 
Chrysomelidae.) 
Early in spring, eating holes in the buds and leaves, a small 
oblong oval flea-beetle, 0.16 long, polished and sparkling, of a 
deep greenish blue color, some of the individuals often deep 
green, purple or violet, their under side dark green and their 
antennae and legs dull black. This sometimes invades the plum 
also, as mentioned p. 362, and it also infests the elm and the alder. 
Its winter retreat is in crevices of the bark and in the earth 
immediately around the root of the tree on which it feeds, and its 
colors are then much less bright and sparkling than in summer. 
See Harris’s Treatise, p. 114. 
Chevrolat in Dejean’s Catalogue has cut up the Chrysomelidae into a multi¬ 
tude of genera. Whether the divisions which he has instituted should be 
received as anything more than subgenera appears doubtful. But however 
this may be, Linnaeus originally gave the name Attica to a section or subgenus 
of Chrysomela, which has since been currently admitted to the rank of a genus, 
with a slight rectification by some authors in tho orthography of its name. 
The species oleracea being originally placed at the head of this genus, must be 
regarded as its type. Therefore, whatever may be tho destiny of M. Chcvro 
lat’s other proposed genera, that which he names Graptodera, under which 
eleracea and our American chalybea are arranged, can in our view be regarded 
only as a synonym. Nothing stable and permanent can ever be reached in this 
part of the science, if old generic names are to be cast overboard in this sum¬ 
mary manner.
