CORN. 
a reddish chrysalis, from which the Fly appears about harvest-time, 
or a little after. In common infestation the shortened upper joint of 
the straw with the blackened channel down one side (as figured), and 
the ear often partly or entirely still wrapped in the leaves, are the 
characteristics of the attack ; but in the past season the whole plant 
was often so exceedingly stunted that the ear itself in some cases was 
hardly observable. 
2—0, Maggot, chrysalis, and fly of Chlorops tceniopus , nat. size and magnified. 
7 and 8, Codiums niger; 9 and 10, Pteromalus micans (parasite-flies), nat. size and 
magnified; 1 and 12, furrowed and infested Corn-stem. 
The first specimens were sent me on July 6tli, from Stebbing 
Vicarage, near Chelmsford, by the Rev. A. R. Bingham Wright; 
these plants were only about 4^ to 6 ins. high, and the forming ear 
quite enfolded in the sheathing leaves, so as (in some instances) to 
give the plant the shape of a long, narrow Maize, or Indian Corn, cob 
on a short stem. The larva was present, but was not full grown, and 
the damage was characteristic in one or two cases, as far as the 
gnawing of one side of the ear was concerned, but not in all, from the 
plant or ear being still so little developed. 
On July 8tli, infested Barley-stems were forwarded to me by Mr. 
T. H. Tliursfield, from Barrow, Broseley, in very similar condition to 
the above. There were very young plants in which the ear was hardly 
developed, or destroyed, so that there was only one ear in which the 
furrow characteristic of Gout Fly attack was noticeable; the stem 
below was quite short and stunted. The Fly was in early pupal state. 
At the same date, specimens very similarly affected were sent 
me from Akenliam, near Ipswich, by Mr. J. A. Smith, with the \
