brighter ochreous, veins less distinct. Thorax and legs bright ochreoua. 

 Expanse 2 inches. 



This insect is allied to the genus Dalcera. It also has much the appear- 

 ance of Ammallo nervosa, Felder, but differs considerably from the latter 

 in both the form of wiugs and in their venation. — F. Moobe. 



Larva, a, Full-fed. San Paulo, April, 1880. 



This remarkable caterpillar was found on the Ameixa 

 {Eriobotrya Japonica) at the end of March, 1880. It is quite 

 white and translucent, looking just as if made of Venetian 

 glass. The abdominal legs are wanting, their place being 

 indicated merely by slight swelling of the skin. The motion 

 of the caterpillar when walking is exactly that of a slug, a 

 series of waves passing along the surface of the abdomen, 

 from the rear to the front.

P^^^- I 24 days. 



Pupation takes place within a cocoon, spun on the surface 

 of a leaf or other suitable place. The cocoon is remarkable 

 for the hexagonal hole left in the outer layer of silk in the 

 centre of the cocoon.

 Imago, j , 



Specimens full-fed at the beginning of April, produced the 

 perfect insect at the beginning of May. When the moth 

 emerges, it protrudes the pupa as far as the abdomen from the 

 cocoon, the empty shell remaining in that position.
