916 General Notes. [ November, 
uals work upwards into the first section of the stalk, but only, it 
would seem, after having consumed all available pith below 
ground. 
At full growth the larva will have consumed the pith of the 
stalk for from four to five inches, dwarfing the stalk, preventing 
the make of the ear, and causing the lower leaves to turn brown 
and wither. The larva has the general characters of other de- 
scribed -larve of the genus. The pupz are found in cavities op- 
posite the first suckers, surrounded by excrement compactly 
pressed so as to form a sort of cell, E 
The beetles make their appearance in the fall (one specimen 
issued as early as August 30), and hibernate as adults mainly in 
the stalks. The remedy then of cutting the stalks in fall or early 
winter and of plowing up and burning the stubble is obvious.—

ture seems essential to the well-being of the larva. The preju: 
dicial effect of drought has not hitherto been observed, that we are 
aware of, but was very noticeable the present year in parts of Ohio, 
where the puparia literally dried up. Our attention was 
called to the fact of the general death of the insect in the pase

intense heat had not only desiccated the Cecidomyia, but, 
‘still more remarkable, in most cases the parasites also. 
like to hear from Prof. Cook, of Michigan, and others, whether 4 
like result followed the severe heat and drought in other parts al 
the West. The presumption is that the mortality was gener’ 
and that farmers may expect immunity from injury for some years 
to come. 
SIMULIUM FROM Lake Superior.—lIn regard to t 
from Lake Superior, which we mentioned on p. 313, CU" fae 
ume of this magazine, Dr. Hagen remarks in the Canadian re a 3 
mologist (Vol. Xt, pp. 150-151), that upon examination “7 ack ie 
and pup, sent to him by Mr. H. G. Hubbard, they di the S 
appear to differ materially from those of S. pictipes, but jer ae 
imagines from Lake Superior (which were not raised green oe 
pupz coliected by Mr. Hubbard) differ from S. pectipes 9 
much smaller size and in the color of the legs.
