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 LampyriSf 

 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." 



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 Geometradce,
