was opake or milky, with hardly any redness about them, though 
the last segment was somewhat faintly tinged with red. But 
there appears in the spines or bristles a peculiarly distinctive cha¬ 
racter, for they are in a single row only, and regularly placed in 
a line, and the microscope could hardly discover that their points 
were black, being minutely so, and hardly visible to the naked 
eye, while the other species were distinctly so to some distance, 
in make and other circumstances they resembled the Equi, but 
were not above half their size. Having stated these circum¬ 
stances, I leave the further investigation of them to the curious. 
The real Chrysalis of Veterinus I once found in the neighbour¬ 
hood of Worcester, in a meadow below Perry Wood, between it 
and the city, under some horse dung ; and the figure of it was, 
as near as I can remember, for I threw it away after the Fly came 
out, much like figure 26, which is done from memory, for at 
that time I had no prospect of ever having to write on these 
subjects. 
This Fly, after it left the Chrysalis, being confined under a 
glass in my window, became, if I remember right, singularly 
active and impatient, and destroyed in its rage one of its wings, 
drawing it towards its mouth with its legs, and devouring it, as 
it appeared, and whirling round with considerable velocity and 
noise upon its back. Whether other flies so confined would do 
the same I know not. 
I think Reaumur’s figures I have referred to are certainly meant 
for this species, but the figures 1 and 2 are evidently two differ¬ 
ent Chrysalides, though given for the same. The one is of Hae- 
morrhoidalis or Equi, the other smoother, and probably of this 
species. Tom. IV. pi. 35. The Larva of this species is not given 
by him at all, but in the preceding plate there is a good figure of 
the Larva of the Haemorrhoidalis, which he considered the same, 
and the Flies 9 and 10 are the Haemorrhoidalis, though badly 
executed. As far as I remember, the Fly of Veterinus, in making
