harvest, but a late one if they abound between the hind feet. The 
appearance of the death’s head hawk-moth (Acherontia Alropos) has in 
some countries produced the most violent alarm and trepidation amongst, 
the people, who, because it emits a plaintive sound, and is marked with 
what looks like a death’s head upon its back, regarded it as the messenger 
of pestilence and death.? We learn from Linné that a similar super- 
stition, built upon the black hue and strange aspect of that beetle, prevails 
in Sweden with respect to Blaps mortisaga® ; and in Barbadoes, according 
to Hughes, the ignorant deem the appearance of a certain grasshopper in 
their houses as a sure presage of illness to some of the family.* 
One would not think that the excrements of insects could be objects of 
terror; yet so it has been. Many species of Lepidoptera, when they 
emerge from the pupa state, discharge from their anus a reddish fluid, 
which, in some instances, where their numbers have been considerable, has 
produced the appearance of a shower of blood ; and by this natural fact, 
all those bloody showers, recorded by historians as preternatural, and 
regarded where they happened as fearful prognostics of impending evils, 
are stripped of their terrors, and reduced to the class of events that happen 
in the common course of nature. That insects are the cause of these 
showers is no recent discovery ; for Sleidan relates that in the year 1553 
a vast multitude of butterflies swarmed through a great part of Germany, 
and sprinkled plants, leaves, buildings, clothes, and men, with bloody 
drops, as if it had rained blood.’ But the most interesting account of an 
event of this kind is given by Reaumur, from whom we learn that in the 
beginning of July, 1608, the suburbs of Aix, and a considerable extent of 
country round it, were covered with what appeared to be a shower of 
blood. We may conceive the amazement and stupor of the populace upon 
such a discovery, the alarm of the citizens, the grave reasonings of the 
learned. All agreed however in attributing this appearance to the powers 
of darkness, and in regarding it as the prognostic and precursor of some 
direful misfortune about to befall them. Fear and prejudice would have 
taken deep root upon this occasion, and might have produced fatal effects 
upon some weak minds, had not M., Peirese, a celebrated philosopher of 
that place, paid attention to insects. A chrysalis which he preserved in 
his cabinet let him into the secret of this mysterious shower. Hearing a 
fluttering, which informed him his insect was arrived at its perfect state, 
he opened the box in which he kept it. The animal flew out and left 
behind it a red spot. He compared this with the spots of the bloody 
shower, and found they were alike. At the same time he observed there 
was a prodigious quantity of butterflies flying about, and that the drops 
of the miraculous rain were not to be found upon the tiles, nor even upon 
the upper surface of the stones, but chiefly in cavities and places where 
rain could not easily come. Thus did this judicious observer dispel the 
ignorant fears and terror which a natural phenomenon had caused.°
