that the white powder has a phosphoric appearance in the living insect, and increases 

 the liffht when the end of the trunk is illuminated. 



" One of the Fulgoraj of considerable magnitude, from the interior of India, enabled 

 us to make many observations. The trunk is of the same form as that of the Fulgora 

 Canddaria ; the colour is a dark but beautiful purple ; the apex scarlet, of a perfectly- 

 pellucid appearance, and still retains a reddish glare ; the spots of white sprinkled on 

 the pui'ple colour of the trunk exhibit also a slight appearance of phosphoric matter. 

 On the trunk of the Fulgora Candelaria these white spots are very conspicuous. 



" Though the generic name Fulgora seems to imply some effulgent property in the 

 insects that compose the genus, it is uncertain whether all possess that property. They 

 are indeed furnished with a trunk, but it is smaller in proportion in several species than 

 in F. Laternaria, Candelaria, Flammea, Phosphorea, and some others. It has not been 

 determined whether any of the European Fulgorse shine in the night-time." *

Though the observations of Sir G. Staunton on the natural productions of China 

 were necessarily very general, the study of insects appears to have engaged his par- 

 ticular attention ; and on that account we must lament that untoward events precluded 

 him from observing more minutely the peculiarities of some kinds, and the economical 



* (Notwithstanding the observations of Donovan and the various authorities cited by him, it is certainly a 

 mattei- of doubt, at the present day, whether the Fulgorse in reality possess any luminous property. No recent 

 author or traveller has noticed its existence in these insects, although it is related in every work of travels as 

 exhibited by the Elateridae and Lampyridse. Moreover, the farinaceous matter noticed by Rosel exists in many 

 other insects known to be not in the least degree luminous, and of which the woolly or waxen appendages in 

 Lysira lanata, the Dorthesiae, Cocci, &c. is but a modification or more extensive developement. M. Wesmael, 

 of Brussels, has, however, just reasserted the luminous properties of the South American Fulgora on the 

 authority of a friend who had witnessed it alive. Ann. Soc. Ent. France, 1837, App. J. O. W.)
