to their boots, for the purpose of giving them light in their 

 nocturnal journeys. Brown will have it, that all the inter- 

 nal parts of this insect are luminous, and that it can suspend 

 at will its phosphoric property. But M. de la Cordaire, who 

 has observed this insect in its living state, has informed me 

 that the principal reservoir of the phosphoric matter is 

 situated underneath, at the junction of the abdomen with 

 the thorax. Our colonists term it " tnouche lumineuse^'' 

 (fire-fly,) and the savages Cacui/os, Coyouyov, from which 

 comes the Spanish name Cucujo. An individual of this 

 species, brought to Paris in some wood, in the larva or 

 nymph state, there underwent its metamorphosis, and by 

 the light which it threw out excited the surprise of many of 

 the inhabitants of the Faubourg St. Antoine, to whom such 

 a phenomenon had hitherto been unknown.
