from the fact that the history of many of them is still unknown, and those species that may 
abound in one particular locality nay be wholly unknown in another. The next most com- 
mon species of these insects belongs to the genus Otiocerus, of which, perhaps, the O. coque- 
bertit is the most common example. These insects belong also to the family Tettigoniide, 
and are nearly of the same size as those of the former .genus I mentioned, but more slender 
in their forms. But as they are more common to the wild grape than the cultivated varie- 
ties, it will be unnecessary to do anything more than to make this passing allusion to them, 
and also to say that there are some 9 or 10 species of them, comprised under the genera 
Otiocerus, Anotia, Brachymorpha, and Naso, and that some of them are of a shining black 
color, and have the anterior portion of the head extended into a cone shape; with very short 
wing covers. In addition to these ‘‘vine-leaf hoppers,”’ there are several species of Thelia, 
commonly called ‘‘ tree hoppers,”’ which are much larger in size than the former, but which do 
not occurin such formidable numbers. These belong to the family Membracide, and in shape 
approach the form of a beech nut; often with a perpendicular protuberance arising from the 
thorax of the males; being of a chestnut brown in color, and about one-third of an inch in 
length, and one-fourth of an inch in height; and one species, Thelia univittata, havinga 
whitish or yellowish stripe along each side, extending from_one end to the other. Another 
species, Acutalis dorsalis, of a greenish white color, with a large black spot on the back, is 
also found on the grape leaves. There are three species of insects belonging to the order 
Hemiptera, or ‘‘ half-wings,” nearly allied to those before named, that are injurious to the vine 
when they happen to occur in great numbers, which, however, fortunately is not often the 
case. The insects are from three-eighths to five-eighths of an inch in length, and very nearly 
the same across the widest part of the body, and are of a green color; and although suffici- 
ently large, one would suppose, to be easily detected, yet so near are some of them to the 
color of the leaves, that they are often entirely overlooked. ‘They belong to different genera, 
namely, Pentutoma, a grass-green in color; Raphigaster, the same color, edged all around 
with a yellow marginal line; and Arma, of a greenish or yellowish gray, with brown punc- 
tures on the wing covers, which, in some species, are red towards the ends These 
insects, like all of the foregoing, are haustellated or suctorial in their habits, stinging 
the leaves and feeding on the sap. But these do not include all the ‘‘sap-suckers” 
that infest the grape vines, for, in addition to these insects are also various species belonging 
to the great family Aphide or ‘‘ plant lice,”’ especially the Aphis vitis and the Pemphigus 
vitifolia, small in size, and generally too well known to need a specific description here. 
But there are other orders of insects found on grape vines that eat up the buds or the entire 
foliage, either in their larva or mature states, or in both; and perhaps the most numerous 
and destructive of these is the ‘‘blue grape-leaf beetle.” This insect belongs to the order 
Coleuptera, and is the Haltica chalybea of authors, and in some localities is known as the 
‘‘ orape-vine flea-beetle.’’ In early spring the adult insects cut off the buds of the vine, and 
later in the season their larvee destroy the leaves, and if left alone, they multiply rapidly, 
and eventually strip the vine of its foliage and destroy the crop. They undergo their trans- 
formations in the ground, and the adults hybernate during the winter season, so that their 
extermination ought to be effected in their larva state; they are thena small brownish bristled 
worm. ‘Then, in addition to these, and belonging to the same erder, we have various species 
of Anomala, about one-third of an inch in length, that feed upon the grape leaves. These 
insects bear a close resemblance to the famous ‘‘rose bug,” only more robust in form, and 
as they ure gregarious, and often occur in great numbers, they become very injurious to the 
vines. The rose-bug itself, Macrodactylus, is very often found on the grape vines when they 
are in bloom, and I have often known them to cause the entire destruction of the crop, by 
devouring the flowers and buds. Last, not least, of the destructive coleopteras the Pelidnota 
punctate, or six-spotted ‘‘ grape beetie.”” This is a large brownish yellow beetle, of various 
shades, found on the vines in the month of July, and is too well known to need a special 
description at this time. 
Of the lepidupterous order there are various species that belong to the Sphinz family, that 
in the larva state feed on the foliage of the grape vine. These belong to the genera Chero- 
campa and Philampelis, and in their larva state are large cylindrical, fleshy worms, approxi- 
mating in form to the ‘‘ tobacco worm,”’ and are of various shades of color, from a pale green 
to a light velvety brown, with oblorg cream-white spots along the sides, and a projecting horn 
from the upper side of the last segment, pointing backward. The matured insects are large 
parti-colored ‘‘hawkmoths,” and they undergo their final transformations under ground. 
They are found on the grape-vines, eating the leaves and sometimes cutting off tue fruit, in 
August and September. Then we have the larvee of Procris americana and Alypia 8-maculata, 
that infest the grape leaves in colonies; usually found on the under side of the leaf, lying side 
by side, and moving along ina body, destroying all except the coarser veins as they go. The 
former is yellow, dotted with black. and the latter is light blue, banded with black. These spin 
a flat cocoon, side by side on the leaf. ‘The former comes forth in the month of July, a small 
black moth, with a bright yellow band around the neck; and the latter in May or June, of the 
same color, but more robust than the former, having yellow shanks, and with two yellow spots 
on each of the fore wings, and two white ones on each of the hind wings. The latter insect is, 
however, not so common as the former. The larvee of the beautiful ‘‘ wood nymphs’’—very 
much resembling the above named, only larger—are also found on the grape vines. These
