RED-BEARDED BOT FLY, 57 
is at all desirable, considering that its maggot life is passed in the 
nostrils, mouth, or throat of the Red Deer. 
As yet, so far as I am aware, we have no record of its method of 
larval life in this country. This will be found given in excellent 
detail in Dr. Brauer’s ‘ striden’; and for practical purposes, as well 
as scientific detail in very readable form, Mr. Grimshaw’s paper, 
which he mentions he has compiled mainly from Dr. Brauer’s and 
Dr. Schiner’s works, will be found very useful,* and with Mr. 
Grimshaw’s permission I drew attention to it in my Nineteenth 
Report, p. 139. 
Now, however, as the presence of the infestation appears to be 
extending, and I have myself seen the fly, I give a few notes, with 
due acknowledgment appended, of what we only know as yet from 
continental observation. 
On June 8th in the past year (1896) Mr. Dugald Campbell, writing 
from Strathconan Forest, Muir of Ord, Ross-shire, N.B., with various 
specimens of two-winged flies forwarded accompanying, noted that 
amongst them were some resembling ‘‘ Humble Bees,” of which he 
asked the name. One of these (figured somewhat larger than life at 
p. 56) proved to be a specimen of U. rufibarbis, the Red-bearded Bot 
Fly of the Red Deer; but happily the species appears to be still very 
rare in the district, as, later in the season, Mr. Campbell wrote me 
that he had only seen one other specimen, which he nearly captured, 
but ‘‘it was too clever for him.” This agrees with Dr. Schiner’s 
description of the habits of this genus, of which he notes that, even 
where seen in great numbers, they “are difficult to take, because 
they seldom settle.” 
This Red-bearded Bot Fly is large and handsome, so clothed with 
hair as almost to appear furry; broad and rotund in shape, and nearly 
three-quarters of an inch long; the head and thorax slightly narrower 
than the abdomen, which in the specimen before me is nearly three- 
eighths of an inch in breadth. The colour chiefly black or brown, with 
various markings, and also interminglings of reddish, olive brown, and 
white hairs. The head chiefly black, but with tawny hair behind, 
and the forehead and part between the eyes variously patterned with 
black, red, and whitish hairs. Antenne (horns) and antennal bristle 
reddish. The cheeks and mouth parts thickly and noticeably clothed 
with red hair, so as to give the appearance of a red beard running 
round the under part of the face, from which the fly takes its English
