HAULM FLY.

The following note is by Mr. T. H. Hart, late of Park Farm, Kings- 
north, Kent :— 
“ Gout or Poddle. — Almost every piece of spring-sown Oats or 
Barley that I walked through was suffering more or less from attack 
of Chlorops tceniopus. In some cases it was of serious importance, in 
CHLOROPS TiENIOPUS. 
2—6,11, maggot, chrysalis, and fly of Chlorops tceniopus , nat. size and magnified ; 
7 and 8, Ccelinius niger; 9 and 10, Pteromalus micans (parasite flies), nat. size and 
magnified ; 1 and 12, furrowed corn-stem. 
others but trifling; still there it was, and the field that looked so level 
and nice from the outside betrayed its weakness on walking though it. 
The Wireworm-struck Oats mentioned were severely attacked by this 
fly after the worm ceased to trouble it, and at harvest-time it was a 
wretchedly untidy piece of Corn, single straws, 4 ft. long, crippled 
down, and surrounded by numbers of weakly backward heads varying 
from a few inches to some 2 ft. in height. 
The Chlorops is a small, very thick-made, two-winged fly of the 
size figured above (fig. 2), yellow, with three black stripes along the 
back between the wings, and having the abdomen greenish black with 
black cross-bands (see fig. 3, magnified). 
The attack affects various kinds of Corn, and in this country 
appears to be most hurtful to Barley. With regard to the method of 
attack, it has not yet been fully recorded in this country, but by 
comparing English and German observations it appears to be as 
follows :—*
