LUMINOUS INSECTS. 4.2] 
the wind may convey the light body of an insect to the 
above-mentioned distance from land, you will not dis- 
pute when you call to mind that our friend Hooker, in 
his interesting Tour in Iceland, tells us that the ashes 
from the eruption of one of the Icelandic volcanos in 
1755 were conveyed to Ferrol, a distance of upwards 
of 300 miles?.—Lastly, to conclude my list of luminous 
insects, Professor Afzelius observed a dim phospho- 
ric light” to be emitted from the singular hollow an- 
tennze of Pausus spherocerus>, A similar appearance 
has been noticed in the eyes of Noctua Psi, Bombyx 
Cossus, and other moths, Chirgscelis bifenestrata of 
Lamarck, a beetle, has two red oval spots covered with 
a downy membrane on the second segment of the abdo- 
men, which he thinks indicate some particular organ 
perhaps luminous*: and M. Latreille informs me that a 
friend of his, who saw one living which was brought 
from China to the Isle of France in wood, found that 
the ocelli in the elytra of Buprestis ocellata were lu- 
minous. 
But besides the insects here enumerated, others may 
be luminous which have not hitherto been suspected of 
being so. This seems proved by the following fact, 
A learned friend4 has informed me, that when he was 
curate of Ickleton, Cambridgeshire, in 1780, a farmer 
of that place of the name of Simpringham brought to 
papers of July 2d, 1810, to have fallen in France the January pre- 
ceding, accompanied by a shower of red snow, may evidently be 
explained in the same manner.
