GRAIN MIDGE. ITS SPOTTED WINGS. 
indieating its ovipositor to bo similar to that of tho wheat midge. The logs are blackish, 
paler yellowish brown on their insides and at base. Tho wings are smoky, iridescent-blue, 
with blackish veins, tho inner vein abruptly bent, with the end straight and nearly transverse; 
no transverse veinlet.

Associated with the wheat midge and supposed to have the same habits with it; a fly of 
the same size and color, but having six smoky spots on each of its wings, and tho joints of 
the male antonnro alternately longer. 
The flies of this spotted winged midge I met with sixteen years 
ago quite common in our wheat fields, in company with the flies 
of the wheat midge. I continued to find them the following year, 
after which they wholly disappeared, and I have not seen an indi¬ 
vidual of this kind since. 
An insect in Germany, the larva of which nestles in the 
straw of barley in the same situation which the Hessian fly 
larva occupies, and which was very injurious to the barley crop 
in the grand duchy of Baden in the years 1813 and 1816, was in 
1817 described by Dr. J. N. Sauter, in an octavo pamphlet of 47 
pages, as we learn from a brief notice of it and its contents in 
Germar’s Magazine, vol. iii, page 366. Dr. Sauter names this 
barley midge the Tipula cerealis , but, as Mr. Curtis observes in 
his notice of it (Jour. Royal Agric. Soc. vi. 151), there is every 
reason to believe it is a species of Cecidomyia. In that case 
another name for this spotted winged "wheat fly of ours will be 
required, and as the present appears to be the most suitable 
opportunity to effect a change, whereby future confusion may be 
avoided, I deem myself justified in withdrawing the name which 
I had heretofore proposed. 
This grain midge was met with quite common from the middle 
of June till the end of August, in tho wheat fields and also among 
the grass in yards and on the windows of dwellings. There also 
occurred on grass and on windows, in the last half of July and 
through August, what I regarded as another species, extremely 
like this, but having the body of a deeper red color, and the 
wings with seven spots, there being three spots instead of 
two along the inner side of the wing. The difference between 
the two species in this respect is very distinctly shown in the 
magnified wings, figs. 3 and 18 of plate ii, the wing of the grain 
midge, fig. 3, having no spot on the apex of the inner vein, where 
one is situated in this species. I named this species Cecidomyia
