BRAZILIAN LEPIDOPTERA. 59 



The moth varies a ^ood deal in colour, some specimens 

 being shaded with a pink colour, especially in the posterior 

 wings. When disturbed it has a habit of curiinc^ up the 

 abdomen and erecting the wings till they nearly touch, back 

 to back, " shamming dead." 



LXXV. — Arsenura erythrinje. 

 Bomhyx erythriiue, Fabricius, Spec. Ins. ii., p. 169. 

 Larva, a, Full-fed, April 11, 1880. Campinas. 

 I took the caterpillar on a species of Bombax, at Campinas, 

 at the end of March, 1880. In the daytime it congregates 

 in clusters on the branches of the tree, feeding at night. A 

 friend in Campinas, from whose tree I took my specimens, 

 told me he had killed hundreds of them time after time, to 

 save the tree from being stripped of its leaves. 



Pupa. 



My specimens were full-fed early in April, and entered the 

 ground to undergo pupation.

Some of the moths made their appearance in August, others 



in September, and I have still (March, 1881) one pupa alive. 



LX.— Attacus Aurota.

Larva, a, Full-fed. San Paulo, Feb. 6, 1880. 



The caterpillar of this species feeds upon a shrub that 

 grows in damp places, usually at the sides of streams or 

 swamps. It is of a pale green colour, with small orange- 

 coloured tufts of spines, which do not appear to have urti- 

 cating properties.
