ANNUAL REPORT OF NEW YORK 
LOCUST. LEAVES AND TWIGS. 
pale orange midge with the sides of its thorax and often three oval stripes 
on the back and the wings dusky, its antennae blackish and of fourteen 
joints in the females, twenty-four in the males, its length 0.12. 
In midsummer the margins of many of the leafets of the locust may be 
noticed rolled inwards upon their under sides for a length varying from 
over a quarter to a half inch, the upper side showing a concavity or rounded 
hollow at this point. This rolled portion is changed in its color to a paler 
yellowish green, and its texture is thickened and succulent. The same 
leaf sometimes has two or more of these folds along different parts of its 
margin. The worm concealed therein is colorless-watery when young, 
becoming, as it approaches maturity, opake and milk-white varied more or 
less with bright yellow. It is long oval, broadest in the middle and taper¬ 
ing thence to a sharp point anteriorly, the opposito end being bluntly 
rounded, and is divided into thirteen segments by transverse impressed 
lines. 
Prof. Haldeman, who described this species in Emmons’s Journal of 
Agriculture and Science, October, 1847, says it, in conjunction with the 
following species, had been so numerous in south-eastern Pennsylvania, the 
two preceding summers, as to kill the leaves upon the locusts, the trees in 
August appearing as though they had been destroyed by dry weather. 
333. Locust IIispa, Aiioplitis scutcllaris y Olivier. (Colooptera. Ilispidao.) 
In July, blister-like spots appearing upon the leaves, within which is a 
small flattened whitish worm, attaining a quarter of an inch in length, 
tapering from before backwards, with projections along each side like the 
teeth of a saw, and with only three pairs of feet, which are placed on its 
breast; eating the parenchyma and leaving the skin of the leaf entire ; 
remaining only a week in its pupa state, in the leaf, and towards the mid¬ 
dle of August, coming out therefrom a small oblong flattish beetle of a 
black color with the thorax and wing covers, except along] their suture, 
tawny yellow, its length 0.25. 
This is the Hispa suturalis of Dr. Harris, (Boston Journal of Natural 
History, i, 147, and Treatise on Injurious Insects, p. 107,) but cannot be 
the species thus named by Fabricius and Olivier, which is stated to have 
the head, under side and legs, yellow or testaceous. It is very plainly de¬ 
scribed by Olivier under the name scutellaris. Though the species is com¬ 
mon in the southern part of New York, I have never met with it in the 
eastern section of the State, where the following which much resembles it 
in its habits and larva, is common. 
334. Flattened locust leaf-mineii, Anacampsis liobiniella, now species. (Lcpldop- 
tera. Yponomeutida).) 
In July, white blister-like spots on the under side of the leaves, occupy¬ 
ing about a fourth of the surface or half the space on one side of the mid- 
vein, containing within a flattened pale green or whitish worm, tapering
