That the number of broods produced on Cornus in spring (which 
must now be inferred) and the time of return migration to grass are yet 
to be determined. 
That in addition to the migratory winged autumn brood there appears 
to exist under certain conditions an apterous form which produces a 
brood of sexual individuals on grass roots the females of which deposit 
eggs the fate of which is unknown. 
HETEROPTERA INFESTING GRASS. 
THE CHINCH BuG. 
(Blissus leucopterus Say.) 
The Chinch Bug is too well known as a grass and grain pest to need 
any special mention in this connection. It may be noted, however, that 
it prefers the annual grasses rather than perennials, and were it con- 
fined to the noxious Foxtails (Setaria) we might have no reason to 
complain, but its fondness for Hungarian grass is too conspicuous to 
pass over. It does not appear to multiply as rapidly in sod land, though 
I have found it in Blue-grass where this alone could furnish it food. 
THE LONG Bue. 
(Ischnodemus falicus Say.) 
Were it not for its elongated form this species could be most easily 
mistaken for the Chinch Bug, for, excepting this peculiarity, it comes 
nearer in appearance to the Chinch Bug than any of the numerous 
species which have been confused with that noted pest. 
Hitherto I believe it has not been classed among insects of economic 
importance. It is, however, quite evidently increasing in numbers in 
this region and should, I think, be mentioned, at least, in this connec- 
tion. That itis a grass-feeding insect is evidenced by its abundance in 
all stages in grass land where other plants are scarce or wanting, and 
would be expected of an insect so closely related to the Chinch Bug. I 
have found it more common in rather low ground, and especially in the 
wild grasses between upland and bottom-land, or along the borders of 
‘sloughs or small streams. 
Whiie only a fall brood of larve, developing in July and August and 
maturing in September, have as yet been observed, it is probable that, 
as with the Chinch-Bug, there are two broods each year, adults of che 
second hibernating and depositing eggs in the spring. 
If multiplying, so as to become a serious pest, I know of no remedies 
to suggest further than those applicabie to Chinch Bugs, and probably 
the most efficient one would be that of burning dead grass and rubbish 
in the fall. 
There are several other species of the Heteropterous Hemiptera, nota- 
bly certain Capsid@ such as Miris affinis and related species, and several 
species of Lygus, which I suspect will be added to our list of grass pests, 
bnt I have as yet made no eareful study of their habits.
