ANNUAL REPORT OF NEW YORK 
HAIRY FLEA-BEETLE. BEETLE DESCRIBED. 
year occurs upon this plant in great abundance, every leaf often 
showing from one to five or six of these beetles upon it. And the 
pota f o leaves are sometimes noticed so profusely pierced and 
riddled with holes that little more than their ribs and veins are 
remaining untouched. Destroying the leaves to such an extent as 
it does in seasons when it is particularly numerous, it must cer¬ 
tainly be quite detrimental to this important vegetable. 
Having given a full account of the larvae and transformations of 
this genus in connection with the Striped flea-beetle, it is unneces¬ 
sary to repeat the same details here. 
The Hairy flea-beetle is eight-tenths of an inch in longth, oval, convex, black, and 
opako or destitute of any glossinoss. It is clothed with thin, short, whitish pubcscenoo. 
Its head is black, with the eyes prominont, and the horns or antennas of a clay yellow 
color, clavate, and ton-jointed, the two basal joints elongated, the third joint a little 
shorter, the tips tinged with dusky. The fore body is covered with fine punctures, and 
shows a transverso groove near tho baso; it is more wido than long, slightly narrowed 
before, with tho sides convex. The scutel is minute. The wing covers have eight rows of 
coarse punctures placed in slightly impressed furrows, with a shorter similarly punctured 
furrow on each side of tho scutel. The wings are largo, transparent, folded and withdrawn 
under the wing covers when not in use. Tho legs aro clay-yellow with the thighs, at least 
tho hind pair, blackish brown and very thiok; tho shanks aro rather short, tho internal 
angle forming a curved Iobo at tho apex, whioh is out off obliquely; tho foot are four- 
jointed, the third joint two-lobed, the apex furnished with two claws; tho hind pair very 
long and inserted on tho inside of the shank, with the basal joint as long as all the others 
united. 
The same remedies which are employed for the striped flea- 
beetle will be equally efficacious for this species. 
This is named the cucumber flea-beetle, Haltica Cucumeris , by 
Dr. Harris. I am not certain that I have ever met with it upon 
the cucumber, all the flea-beetles which have occurred to my obser¬ 
vation upon that plant proving, upon close examination, to be not 
this species, but the very similar one named Psylliodes punclulata 
by Dr. F. E. Melsheimcr. In one instance where potatoes and 
cucumbers were growing side by side, and the potato leaves 
abounded with this species, I made a careful search for it upon 
the cucumber leaves, but without being able to find a single indi¬ 
vidual, all the flea-beetles thereon proving, when carefully in¬ 
spected, to be the punctulata.
