128 INSECTA. 



female generally without wings. They are nocturnal Insects, 

 lying concealed among the grass in the daytime, and only 

 issuing at night; the female then emits a bluish phosphorescent 

 glow. 



GENUS III. ANOBIUM, Fab. 



Body round; head covered by the corselet; these Insects 

 gnaw the wood of old furniture, and in the nuptial season 

 call each other by striking the head upon the surface of solid 

 bodies, after fixing themselves there firmly with their claws ; 

 the noise thus produced has procured them the vulgar appel- 

 lation of Death-watch. 



FAMILY III. CLAVICORNES. 



Antennae in form of a club. One remarkable genus. 



GENUS DERMESTES. 



Body somewhat depressed; antennae longer than the head; 

 the larvae attach themselves particularly to the skin of dead 

 animals ; the perfect Insect lives upon flowers. 



FAMILY IV. LAMELLICORNES. 



Antennae terminated by a collection of lamellae arranged 

 like a fan, or the leaves of a book; the anterior part of the 

 body generally projects in the form of a hood. Three re- 

 markable genera. 



GENUS I. SCARAB^BUS. 



Body thick and convex ; hood exceedingly short ; flight 

 heavy, and in a right line. They inhabit the hot regions of 

 both continents. 



GENUS II. MELOLONTHA, Fab. 



Hood wide and square ; elytra hard and long ; antennae 

 with ten articulations, of which five or seven in the males, 

 six or four in the females, compose the club ; larvae soft, elon- 

 gated, and known by the name of White Worms. 



GENUS III. LUCANUS. 



Body flattened ; head at least as large as the corselet in the 

 males, who often exhibit well developed mandibles.
