beetles fed. They readily broke away the wood to 
obtain the saccharine matter ; and after his stock of 
canes was consumed, they ate brown sugar ; and 
were kept alive the whole of their voyage from June 
to the middle of September. (Zool. Journal, vol. 
iii.) Of the two kinds of luminous beetles which we 
possess, the Elater noctilucus^ with the large phospho- 
rescent tubercle on either side of the thorax, produces 
the wire-worm of the corn-fields, — the Lampyris, 
which we call the Blinker^ has not been traced 
through its transformations. It is usually found on 
the trunks of trees, and in a state of inactivity ; ^ — 
during the day it clings to their bark or is concealed 
in their fissures.” 
CYDIMON. 
Two species of the genus Cydimon, the one C, 
lunus of Cramer, the other considered by my late 
lamented friend, Edward Doubleday, Esq., as new, 
though closely resembling the former, I have occa- 
sionally found in the summer months around Content, 
but very sparingly. The genus is interesting, as 
being, like Urania^ one of those dubious forms which 
connect the Butterflies with the Sphinges. In habit, 
as well as in form and coloration, Cydimon is more 
allied to the Moths than Urania is ; for, as far as my 
observation goes, I believe it to be exclusively cre- 
puscular, if not nocturnal, in its activity. The few 
specimens that I have taken, have all been found 
resting on the walls and in the angles of houses, in 
the morning, just in the manner of the GeometradcB^
