In The Naturalist for November, 1911, page 380, I gave a 
figure and description of this mite from an old mounted speci- 
men made by me many years ago. Recently I have had a 
specimen preserved in 
spirit sent to me, and 
31 r. Soar has kindly 
made a drawing of it 
before it was mounted, 
avoiding the distortion 
produced by pressure. 
It will be seen that in 
general shape it greatly 
resembles Trombidium 
holosericeum, * being 
rather square, and pos- 
teriorly slightly emar- 
ginate, not rounded. 
The eyes are petiolated, 
each having two ocelli. 
It is, however, a much 
smaller mite, and has 
none of the long silky 
hairs on the fore part 
of the dorsum seen on 
holosericeum. The back 
of this mite is covered 
with trumpet shaped 
hairs or papilla, the 
distal end of each en- 
larged, circular, and 
crenated (see enlarged 
figure) and not being 
very closely pressed to- 
gether, they give the 
mite a very rough ap- Trombidium buccinator. 
pearance, when seen 
under a rather low 
power. They also retain much of their beautiful colour, 
even after mounting in Canada balsam. The crista cannot be 
well seen, so that I have not been able to obtain a figure of 
that organ.
