NATURALIST. 
Here they have reached their destination ; and here, or in 
the intestines, they thrive and increase in size until full 
grown, when in spring they are voided with the faeces, as 
the one you found. They are supposed by some to produce 
a painful, and sometimes fatal disease, to which horses are 
at this season subject ; others, however, believe the presence 
of these insects to be even conducive to the health of the 
animal by their stimulating effects. 
C. — ^ I have taken several new moths within the last 
ten days, some flying in at the window at night : Noctuce 
and GeometrcE. 
F, — Yonder is the carcass of a lamb, thrown out to 
putrefy, with no regard to the olfactories of passers-by. If 
your entomological zeal is sufficient to overcome your disgust 
at the scent, you may probably find some large and hand- 
some carrion beetles under it. 
C. — Oh, I don't much mind the smell if I can obtain any 
fine specimens. If you will stay here, I will examine it. 
F. — Well, have you succeeded ? 
C. — Yes : there are multitudes of beetles of many dif- 
ferent species crawling about it. Most of them were a 
black species of Sylph, the elytra covering the abdomen, ex- 
cept when the latter is elongated, the thorax broadly mar- 
gined with pink ( Thanatophilus marginalis) : another 
species was numerous, much larger and handsomer, the 
elytra almost as long as the body, longitudinally ridged, and 
having a transverse row of red spots near the hind margin : 
the rest of the insect is black f Necrodes Surmamensis J. 
There were numbers of Staph^/linidce, the Fish-beetle of 
Newfoundland ( Siaphylinus Villosus), the beautiful Gold- 
tailed Rove-beetle ( Staphylinm Chrymriis ) , and other 
smaller kinds. I also took a small black Hister ( H, Hm^- 
risiij, and a little lamellicorn beetle, with the thorax elon- 
gated into a projecting horn, and having another horn on the 
head (Pathophagus latibrosiis J •
