The Spotted Willow Aphis.—Found on branches of Gray Willow\ De- 
ribed as Lachnus dentatus, n. sp., as follows: 
Length, two twelfths of an inch: expanse of the wings, six tenths, 
lack; abdomen, dark ash-colored, with six transverse rows of black dots, 
ntennae, Aliform, as long as the head and thorax; two basal joints, short 
id stout, the third as long as the three terminal ones united; these three 
pial. Proboscis, greenish yellow at base. Fore wings, with the usual 
out subcostal vein, and a very elongate stigma; three discoidal veins, 
xclusive of the stigmatic vein,) much wider apart at their tips than at 
leir bases; third vein, two-forked; hind wings with a sub-costal and two 
Lscoidal veins, the latter very closely approximate at base and divergent 
L tip. Thighs, dark honey-yellow, broadly tipped with black; tibiae, 
risky; reddish at the base. The honey tubes are sub-obsolete. The dots 
i the abdomen are very distinct, especially on the fully-grown wingless 
idividuals. In the intermediate rows, the dots are six in number, the 
vo middle ones being smaller than the others. Just behind the middle 
I: the abdomen, and occupying the place of the two middle dots in the 
>urth row, is a somewhat conspicuous black, conical protuberance, vary- 
ig in size in different individuals, and sometimes considerably more prom- 
lent than is represented in the Agure.” 
Similar species mentioned. 
The Willow Bark Louse (Mytilaspis solids , n. sp.).—Received from Stark 
o. on twigs of gray willow. BrieAy described as “a pure white bark- 
■use scale, of about the same size as the oyster-shell bark-louse of the 
3 ple tree, being about one tenth of an inch in length, but of a more 
igularly oblong, oval shape, and exhibiting but little of the curved or 
tussel-shell form, which gives the scientiAc name to this genus of Coc- 
dse, and resembling more nearly, both in form and color, the scales of 
le bark-louse of the pine. They also resemble this last species in having 
lood-red eggs.” 
Eggs about seventy-Ave under each scale. Attempt to transfer young 
ce from twigs to growing willow unsuccessful.

The Grasshopper Parasite.— Atoma gryllaria, n. sp., described as follows : 
“They are of an oblong, oval form, moderately convex and having an 
neven surface, produced by four shallow depressions on the upper side, 
ie two larger near the middle, and the others behind them. The body 
as also two slight constrictions, giving it the appearance of being divided 
ito three segments: but the impressions arc superAcial and only visible
