CYLINDRELLA GRACILIS.

ance of the inmates. The insects flock to the candle- 
shades, and spread themselves over the table, and 
especially crowd upon books, papers, or any other 
white materials. Their four wings, which are ample, 
are of a dull brown colour, possessing little trans- 
parency. Presently we are surprised to see several 
dismembered wings lying about ; and, looking at the 
insects more carefully, we perceive that they are 
casting these organs voluntarily, which seem to be 
annoying encumbrances rather than serviceable parts 
of their bodies. They are seen to throw the wings 
very far forward towards the head, and then suddenly 
jerk them back ; these motions soon dissever their 
connexion with the thorax, which appears to be very 
slight. 
RIDE TO KILMARNOCK. 
March Srd. — Rode from Content to Hampstead, 
and thence, along the summit of the Luana moun- 
tains, to Kilmarnock ; returning through the Bamboo 
walk of Grand Vale. Near Hampstead, by the side 
of the road, half-hidden among the luxuriant herbage, 
was a large mass of stone which I alighted to examine. 
Beneath the ledges, adhering to their under surface, 
were many specimens of a pretty white shell, Cylin^ 
drella gracilis. The delicate pointed spire seems less 
deciduous in this than in other species, for most of 
the individuals were perfect. 
At the summit of the mountain are two elevated 
peaks of a rounded form, about half a mile distant 
from each other ; on the very apex of each is a 
dwelling-house, the one of which is named Highgate,
