In its habits it closely resembles the allied species noticed

When full-fed the larva attaches the upper end of the case 

 to a twig, and pupation takes place.

Larva, a. Full-fed. San Paulo, April 20, 1878. 



I found specimens in the penultimate stage at the begin-

 April 12th, and the caterpillars were full-fed on the 20th.

Pupa, a, Full-fed, April 20 ; Imago, Aug., 1878. 



The caterpillar enters the ground to pupate, and forms a 

 tough cocoon, into which are woven small particles of earth. 



a, Full-fed, April 20 ; Imago, Aug. 10, 1878

The specimens full-fed on April 20th, produced the per- 

 fect insect at the beginning of August.
