nous character of the whole tribe. Again, M. 
Richard reared a species of Fulgora, but never 
saw it shine; whilst a friend of M. Westmael as- 
sured him he had seen F’. laternaria luminous when 
alive. 
Mr. Smith, of the British Museum, has related 
to me an anecdote which confirms the opimion 
that the Fulgora are certainly luminous. Whilst 
curator of the Entomological Society, he was one 
day showing some insects to Lady Seymour, her 
son, a young midshipman, and one of his com- 
panions. ‘The two latter had wandered to a case 
of Hulgora, when one of the boys exclaimed, 
“ Why, look here! these are the Candle-flies that 
we used to knock down with our caps in, China.” 
Besides this, Dr. Donovan has carefully figured 
these ulgora, and his figures show them in the 
act of’emitting light from the points of their pe- 
culiar proboscis. 
The group of Lulgora 1s, however, very little 
known; we know scarcely anything of their 
habits, except that they appear to be mght-msects : 
they merit assuredly a more complete history. 
In the family of Lepidoptera, which includes 
Butterflies, Moths, etc., a phosphoric hght has 
been observed in the eyes of Noctua psi,—a little 
erey nocturnal moth, which has upon its upper 
wings a few black spots resembling the Greek 
letter psi.
