THE HERA. 



appendage at the extremity of the body, from which a pair of long and delicate fila- 

 ments can be thrust or withdrawn at pleasure. This caterpillar constructs a cocoon of 

 wonderful strength, composed of bits of wood cemented together, and of such hard- 

 ness that a penknife cannot penetrate it without risk of being snapped in the attempt. 

 The GIPSY-MOTH differs much in its coloring, according to the sex, the male being 

 blackish brown and the female grayish white. The upper wings of both sexes are 

 marked with four waved transverse bands of moderately light brown, and a dark brown 

 mark near the middle of the front edge like the letter V, inside of which is a blackish 

 spot. On the Continent this moth is very abundant, and the caterpillar is often ex- 

 tremely injurious to the trees.

At the upper left-hand corner of the engraving may be seen another moderately 

 winged moth, called the PALE TUSSOCK-MOTH, the name being derived from its color 

 and the tufts of hair that decorate the body of the caterpillar like tussocks of grass 

 upon a field. The caterpillar goes by the popular name of the Hop-dog. The color 

 of the Pale Tussock-moth is light brownish gray, the fore wings being diversified with 

 several marks of blackish brown, the shape and dimensions of which may be seen by re- 

 ference to the engraving. The hinder wings are much paler, and the band is dark brown. 



The last specimen in the illustration is the HERA, a moth belonging to a genus which 

 is known in England by the beautiful DOMINULA or SCARLET TIGER-MOTH, with its rich 

 green and scarlet wings. In the present instance, the fore wings are cream-colored with 

 broad markings that look at first sight as if they were black, but when viewed in a good
