Reports of Consulting Entomologist. 
This attack is easily known by the barley ear being often unable 
to free itself from the swelled leaf sheaf, and the plant being more 
or less stunted ; also by the black channel showing the course of 
maggot injury down one side of the stem from the base of the ear to 
the uppermost knot. 
I have repeatedly in my reports drawn attention to the im- 
portance of finding where this winter condition was passed in this 
country, that we might make advance towards cutting off the 
nurseries of summer attack, but until Mr. Whitehead placed his 
specimen in my hands we have not had any information sent in on 
the subject. 
Mr. Whitehead on the 11th of May informed me that in the 
middle of April young wheat plants had been sent him, with 
chrysalids in situ near the base of the stem, from which on that day 
Chlorops tceniopus had emerged. A few days later he forwarded 
specimens for my examination, and I found the brown chrysalid 
of the Chlorops lying as he described in the heart of the plant, so 
near development that I could see the fly through the transparent 
chestnut brown case. 
The widened leafage of the shoot which is a characteristic of the 
attack was also noticeable, and the fly on technical examination 
proved to be the Chlorops tceniopus. At first I did not feel certain 
of it being of this species of Chlorops, and therefore submitted it to 
the skilled examination of Mr. R. H. Meade, of Bradford, who 
kindly told me that he thought at first it might be the Chlorops 
nasuta, which is a very variable species, but on close examination 
he was convinced that it was a female of Chlorops tceniopus. 
It is somewhat curious that this attack should be in wheat, 
whereas our common Chlorops in its summer stage in this country 
chiefly attacks barley. I think, therefore, that it would be very 
desirable to watch for what may happen in the neighbourhood of the 
infested land, as we may find this variety of C. tceniopus may have 
some special habits. Although it is probably too late now to search 
for injured shoots, yet when spring comes round again it will be 
well to be on the watch betimes for Chlorops-infested plants, which 
(without going into technical minutia?) may be known by the 
widened leaves of the attacked shoots. If once these were gene- 
rally known by sight, whether in wheat, barley, or very especially 
in wild grasses near corn fields, we might have a good chance of 
lessening the summer presence very effectively by reducing the 
winter nurseries. 
On some of the more advanced specimens forwarded by Dr. 
Fream there was excellent example of the uninjured stem being 
able to make good growth, whilst the infested shoots at the base 
perished, thus showing that the wheat plant being hearty will help 
to carry it over this form of attack, though it does not lessen the 
amount of infestation spread from it. 
Inquiry is constantly sent regarding insect attacks, and there is 
steadily continued application for information regarding warble 
prevention. Eleanor A. Okmerod.
