SATURNIA MAI A. 155 
referred to is yellow, with a broad dark-coloured 
stripe along each side, and two reddish tubercular 
spots on the back of each segment ; head, anal seg- 
ment, and legs purjjlish-red ; each segment with a 
series of setose spines. We are informed by Abbot 
that this moth is called in America the Buck-fly, 
from an erroneous vulgar notion that bucks breed 
its caterpillar in their heads and blow them out of 
their nostrils. This opinion originated from the fly 
coming out in the rutting season, while the bucks 
are pursuing the does. The hunters therefore take 
notice of the insect, in order to know the proper 
season for their sport, which is later in Georgia 
than in Virginia, as is the appearance of these flies. 
They are much the most plentiful in the last men- 
tioned country. One of the caterpillars in Virginia 
went into the ground the 1st July, and came out 
20th October. In Georgia the same species buried 
itself June 14th, and the fly did not appear till 
December 8th, after which other individuals kept 
coming out from time to time till February 16th. 
The male appears by day, and flies very swiftly, 
mounting and descending. The caterpillar stings 
very sharply : when small, the whole brood feed 
together, but they disperse as they grow large.
