CAPTURE OF ATTACKING FLY.

one field where there was a thick open grove of oaks with a shed 
beneath it, within and around which the herd sheltered themselves 
and picked the hay which might be strewn about.—E d. 
The following note refers to the above point, and likewise to 
housing at night, which may prove important relatively to some of the 
(E strides being exceedingly lively in the bright moonlight:—“I seldom 
get any warbles in my own young cattle, and I think from this cause, 
—that they have sheds to run under during the summer, and are housed at 
night, and have a good feed of cake," &c.-—E. R. Berry Torr, West- 
leigh House, Bideford. 
It would be useful if we could have more notes on the above heads, 
for if water and tree protection are to be depended on as preventive of 
attack something might often be done to give this to the cattle simply 
by leaving gates open. It is not a question of making ponds, or 
building sheds, or going into expenses, but in many cases of letting 
the cattle have the benefit of what exists. 
The following communication gives an example of an animal who, 
by special circumstances was feeding on tether where most of the herd 
were house-fed in hot weather, broke his tether and came straight home 
for protection on attack. The Warble Fly itself is seldom captured, 
but I was fortunate enough in the summer of 1887 to have two speci¬ 
mens sent to me by Mr. W. S. Richards, of Ratliturret, Warrenpoint, 
Co. Down, Ireland. The first was forwarded 
on the 80th of June, with the observation :— 
“It seems that when the cattle hear it in the 
air they are off. It does not seem to do more 
than rest on the cattle for less than a second. 
My cows are docile; I can stand near them 
and watch. Bees of different kinds they took no 
notice of, but knew the hum of this insect.” On 
the 17th of August Mr. Richards sent me the 
second very beautiful specimen, which was quite soft and uninjured 
when I received it. From the downy appearance the insect looked 
exceedingly like a good-sized bee (only with one instead of two pairs 
of wings), and the black baud across the body between the wings, with 
a yellowish band before it, also the blackish band across the abdomen, 
and orange colour at the tip showed well (see figure, p. 1). Mr. 
Richards wrote accompanying, after alluding to my previous letter on 
Ox Warble Fly. “ We have been since trying to catch some more, 
and, though we had several chases, only were able to get one this 
morning.This one flew at the legs and flanks of a young 
Guernsey bull; he broke tether and came home, the fly still at him ; 
we got them both.All my cattle are on tethers, and liouse- 
fed by day in hob weather, excepting six before mentioned” (referred
