ANNUAL REPORT OF NEW YORK 
MIDGE. PARASITES. IT IS I'ODND TO BE THE EGG PARASITE OP A BUG. 
parasite pertains to the midge. There are more -indications of 
its belonging to the aphis, though it may be the Chlorops or some 
other common insect of our wheat which attracts it into the fields 
of this grain. It is scarcely worth while to speculate upon this 
subject when the exact truth can be ascertained by careful inves¬ 
tigation. Of one fact, however, we are sulliciently assured, if 
this insect is parasitic upon the midge it has not power to sub¬ 
due it, or to make any sensible impressidn upon it, else the midge 
would not have been pursuing its career all along, so unchecked 
as it evidently has been. 
[When on the point of dispatching these pages to the printer, 
I happen to notice some figures which were sent for my inspec¬ 
tion in August, 1859, from J. M. Klippart, Secretary of the Ohio 
Board of Agriculture. Mr. Klippart found adhering upon a chaff 
of wheat several small black globules. On magnifying them they 
were seen to be flattened or sunk in at their summits, with a row 
of about fifteen little thread-like spines radiating from the edge 
of this flattened portion. On opening one of these globules he 
found it hollow and containing a little sac within, in which were 
wings and legs which in his view were “ certainly portions of 
Platygaster punctiger," accompanid by “ genuine antennas of 
Cecidomyia Tritici.” I assured Mr. Klippart the figure of the 
antennas showed they were not what he supposed, but were 
unmistakably parts of the same insect to which the wings and 
legs belonged. And on noticing this antennas figure now, I see 
it corresponds with my fig. 4 a of Plate i, in such particulars as 
assures me it pertains to the same insect. And this insect Mr. 
Klippart found in the little black globules. I now perceive what 
the facts are in this case. I think I informed Mr. Klippart that 
these globules looked to me like the eggs of a Hemipterous insect. 
Now that my mind is refreshed upon the different insects which 
occur on our wheat, I can state with a considerable degree of 
confidence that these globules, according to the figures given of 
them, are the eggs of the JYabis fera of Linnaeus, a long narrow 
ash-gray bug slightly over a quarter of an inch in length, which 
is common on wheat and very common on grass, both in this 
country and in Europe. I hope to have the dissimilar habits of 
this and the other bugs which occur on our wheat sufficiently 
investigated, to present an account of them in my next Report. 
This Mistaken parasite, thus found in those eggs, sufficiently sot-
