484 THE CAPRICORN TRIBE GLOW-WORM TRIBE. 



farinncions parts of th» grain on which thej feed. Corn-h)fts are 

 often laid waste by these grubs, whose numbers are sometimes so 

 prt'.nt, as to devour nearly the v/liole of their contents. When the 

 ^i ab has attained its full size, it still remains within the grain, hidden 

 under the empty husk. There, being transformed, it becomes a chry- 

 salis; and, when it has attained its perfect state, it forces its way out. 



It is no easy matter to discover by the eye the grains that are thus 

 aUacked, for, in external appearance, they are still large and full. If, 

 however, they be thrown into water, their lightness soon detects 

 them. 



To rid a granary of these destructive insects, it has been recom- 

 mended to farmers to spread their corn in the sun, when the Weevils 

 will creep out of their holes; and by often stirring the corn while in 

 this situation, it is supposed they may be completely expelled. It is 

 also said that they may be destroyed by strewing boughs of elder, or 

 branches of henbane, among the corn. In a late Paris paper, a gentle- 

 man says, tliat about the month of June, when his granaries and 

 barns, that had been much infested by Weevils, were all empty, 

 he caused a number of the hills of the large ants to be collected in 

 bags, and placed in dift'ereut parts about them. The ants immediately 

 attacked the Weevils that were on the walls and other parts, and 

 destroyed them so completely, that in a very short time not a single 

 AVeevil was to be seen; and since that period, he says, they never 

 appeared on his premises. 



OF THE CEKAMBIX, OR CAPRICORN TRIBE. 



The insects of the present tribe are among the most beautiful that 

 are known. Their antennae are frequently longer than the body. 

 Many of the species diffuse a strong smell, perceptible at a great 

 distance ; and some of them, when seized, emit a sort of cry, produced 

 by the friction of the thorax on the upper part of the abdomen and 

 wing-cases. 



Their larvce are found in the inner parts of trees, through which 

 they bore, feeding on and pulverizing the substance of the wood. 

 They are transformed into perfect insects in the cavities they thus 

 make, and never issue from their retreats till they have attained their 

 perfect state. 



OF THE LAMPYRIS, OR GLOW-WORM TRIBE. 



The name of this insect is derived from the luminous appearance 

 of the posterior part of its abdomen. The males are all winged, but 

 most of the females are destitute of wings. In some of the species the 

 males are not luminous. The larvae, which feed chiefly on plants and 

 leaves, nearly resemble the females in appearance. 



There are about sixty known species, inhabitants of diflferent parta 

 of the world.
