Eye-plants, the leaves were yellow at the tips, and gnawed and decayed 
at the root so that the heart-leaves could be drawn out. By the 
25th of April some maggots were going into the earth to change to 
chrysalids, and by the 9th of May both chrysalids, and maggots nearly 
ready to change to chrysalids, were observable. From the 20th of 
May onwards the flies appeared in the early morning, at first only 
males, afterwards females ; they appeared up to the 8th of June, and 
still some chrysalids remained.”* 
Dr. Taschenberg further observes “ that this widely-distributed and 
common fly develops at least one more brood is evident, but how and 
where I have not yet made out; whether it may resemble the winter 
attack, only be in grasses allied to Wheat, or may come from manure, 
or where?” 
This is what we still need to make out. It is plain, as previously 
remarked, that the fly that lays its eggs on the young .Wheat sown 
after summer fallow cannot be the same fly that came out in June; 
but where the intermediate generation has fed in maggot condition, 
and changed to chrysalis and fly, is what we need to know before we 
can deal with this attack.

The following observations are merely given to record the great 
amount of Hop Aphis which appeared late in the season,' as it may 
prove of use to notice whether this is followed by absence or presence 
of Hop Lice and Fly next spring.
