CORN. 
The chrysalis-case (8) is reddish brown. The fly (4) is of various shades 
of grey and black, the females having the abdomen, as well as the fore 
body, of a pale ash-grey, and the four hinder thighs, as well as the 
shanks, pale (there is some variation in depth of colour of the legs). 
At (5) a young Wheat-plant is figured slightly torn open, to show the 
injured centre. 
The first specimens of this attack in the past season were sent me 
on April 5tli by Mr. Wm. Parlour, of Middle Farm, Dalton-on-Tees, 
Darlington. The larvae were still white and tender, but in the most 
developed specimens the two squarish central teeth with one on each 
side were clearly to be seen, and in one instance at least other small 
Hylemia coarctata.

teeth outside the two pointed ones were slightly noticeable, as some¬ 
times occurs with this kind of maggot. The centre of the young 
Wheat-plant was quite cut through within. Of these Mr. Parlour 
noted :—“ I enclose some specimens of Wheat containing a maggot. 
The maggot is not so large as those of H. coarctata I sent last year, 
but it is earlier, and may not yet have attained its full size; the appear¬ 
ance of the field is identical with ours which was attacked last year. 
I took them from a neighbour’s field last night. The greater part of 
the Wheat is already dead, and there cannot possibly be more than 
half a crop on it.It was in fallow last year.” Somewhat 
later, that is, on May 2nd, Mr. Parlour furnished me with more 
specimens, the plants in this case being small and almost eaten out, 
and favoured me with the following notes, which I give almost in 
extenso, as they convey various points of useful information, some of 
them confirming previous observations on such points as to special
