fuo Mari in coitu deprehendi, &c. The fame which hap- 
pened to me, for I once:Caught the Male, and Female 
coupled, and could obferve no Difference between them^ 
except in Size, the Female being a little the larger, for 
they both fliined alike. Its Light was very vivid fo as to 
be feen plainly when a Candle was in the Room ^ but the 
vibrations thereof were unequal, and the Colour gree- 
nifli like that of the creeping Glow- worm. The lumi- 
nous part was two fmall fpecks on the under fide of the 
Tail at its End. The fhineing continued for a little while 
after the Tail was cut off, tho' it fenfibly decayed, till 
at laft it went quite out. Whether it fhined longer-then 
the Life remained in that part (^which will live for a 
confiderable time in all Infedls after it has been fevered 
from the body,)'! much doubt ; and Moufet fays Cla- 
riflimum iftuin fplend.orem juaa cum fpiritu vitali 
prorfu^ evanefcere. PofEbly the ufe of this light is to be a 
Lantern to the Infed: in catching its prey, and to dired

Pofition of it on the under part of the Tail, fo that by 
bending the fame downward |as I always obfer ved it to 
do,> it. gives a light forward upon the Prey, or objed:.
