AGRICULTURAL REPORT. 
THE DARK-SHADED CETONIA. 
Cetonia Melancholica. 
The beetle shown on PI. VIII. fig. 9 is found on those bolls 
which have been bored into by the boll-worm, extracting the flowing 
sap from the lacerated sides of the wound. As many as five have 
been taken from the interior of a single boll, which had been pre- 
viously hollowed out by the worm, and where the sap was flowing 
very freely Some planters accuse them of making the holes in 
wfiicli they are found ; but most of the bolls examined by me had 
evidently previously been hollowed out, and the beetles had only en- 
tered for the sake of th$ extravasated sap. Sometimes, however 
they may so abrade the skin of a boll as to cause a flow of juice, of. 
which they will avail themselves, as I have occasionally observed 
solitary individuals sucking the sap under very suspicious circum- 
stances, where no previous wound had been made by the worm. 
They can do but little harm, however, to the crop. 
This bettle is rather more than half an inch in length ; ot an 
ovoid form ; greenish, with somewhat oi a metallic lustie , across 
the win°*-cases, are several whitish spots and 6liort lines , the tail is 
obtuse, hairy, and protrudes beyond the wing-cases ; the legs are 
rather spiny, of a dark color and metallic lustre. 
THE INDIAN CETONIA. 
(Cetonia inda.) 
I observed another beetle, (PI. VIII. fig- 10,) but very abundant, 
in the blooms, and sometimes in the open bolls of the cotton, m hlori- 
da, in October, which apparently did no injury. This beetle is 
three-fifths of an inch in length, and of a brown color, spotted and 
marbled with a darker brown and black. It flies with a loud-hum- 
ming sound, and is apparently sluggish in its habits when not on 
the wing. 
INSECTS FOUND ON ROTTED BOLLS. 
Much has been said about the rotted bolls of cotton, the cause of 
which has been attributed to insects ; and it has been alleged that, 
if these bolls Were well examined, several of the insects causing the 
disease would always bo found inside. It is true, jnany small 
insects are found in such rotted bolls, but they have invariably been 
previously cracked or split open by disease, or bored into by the 
boll-worm The fact is, the insects found in such places frequent 
them merely for the sake of the sap which exudes from the wounds, 
or for the fu-ngoid growth that generally flourishes in such situations.
