interwoven ; at each end of the cocoon several small holes 

 are left in the weaving. Pupation does not take place for a 

 considerable time after the cocoon is spun. 



Imago, a, Full-fed, March ; Imago, Oct. 28, 1878. 



The moth appears in October, seven months after the larva 

 is full-fed. This moth and other allied species have a pecu- 

 liar and disagreeable odour. On emergence from the cocoon, 

 the head and thorax of the pupa are protruded, and the empty 

 shell will be found in that position in all cases where the 

 moth has come out. 



LXXXI. — Megalopyge sp- 



The specimen, a female, is too much broken for identification. It has 

 a reddish woolly body, the wings apparently grey, with indistinct blackish 

 streaks between the veins. - F. Moore. 



Larva, a, Full-fed. San Paulo, March 16, 1878. 



The caterpillar feeds on the Cedrela, and is full-fed in 

 March. It sometimes appears in such quantities as to strip 

 the trees of their leaves. The body is covered with beautiful 

 bright chestnut hairs that lie in wavy ridges down the body ; 

 round the sides the hairs are black, and two curious forked 

 black tufts of hair arise from the ends of the caterpillar.

Pupa, a, Dec, 1880. 



The cocoons are spun in great clusters on the trunk of the 

 tree, fifty or a hundred being often found in one cluster. 

 The outside covering is thick and woolly, and inside this is 

 formed the hard cocoon. This is ovoid in shape, with the 

 anterior end flattened where the trap-door is formed through 

 which the moth makes its exit.
