willow-trees. They conceal themselves' during the day; in the 

 evening they open the immense cases with which the upper part 

 of their body is covered and defended, and then unfold their 

 beautiful wings of the finest texture, and fly abroad, and feed on 

 those leaves which afford both enjoyment and support. 



The Musk-Beetle — The beautiful beetles, of which the 

 common Musk-Beetle is an excellent example, vary considerably 

 in size ; some being several inches in length, while soaie are hardly 

 one-guarter of an inch long. The extreme length of their antennae 

 is the most conspicuous property, and from that peculiarity they 

 are at once recognized. 



The Musk-beetle is a large insect, common in most parts of 

 England. Its peculiar scent, something resembling that of roses, 

 often betrays its presence, when its green color would have kept 

 it concealed. When touched, it emits a curious sound, not unlike 

 that of a bat, but more resembling the faint scratching of a per- 

 pendicularly-held slate-pencil. Its larva bores deep holes in the 

 trees, which are often quite honeycombed by them.
