BRAZILIAN LEPIDOPTERA. 37 



Jrt,Feb., 1881. 

 Pupa. |^^ Full-fed, Jan. 17 ; Imago, Jan. 31, 1881 = 14 days. 



The caterpillar hangs itself up by the tail to change to the 

 pupa state. 



Imago, a, $ h, ? . 



The butterfly appears fourteen days after the larva is full 

 fed. 



[Note. — This variety differs from a typically marked specimen in the 

 British Museum Collection, in the forewing of both sexes having a broader 

 medial transverse blackish area, owing to the absence of the red spot be- 

 tween the base of the upper and middle median veins, and the small size of 

 the spot between the middle and lower median veins. The hindwing differs 

 also, in having a broader medial angular transverse black area, and a broader 

 black outer marginal band. — F. Moore.'] 



Subfam. TIelieoniince. 



LXIX. — EUEIDES DiANASA. 



Nereis Dianasa, Hiibner, Samml. Exot. Schmett. (1806-16). 

 Larva, a, Full-fed. San Paulo, April 25, 1880. 



The caterpillar feeds on a species of Passion-flower, and 

 was found full-fed at the end of April, 1880. 



Pupa 1^' Full-fed, April 24; Imago, May 14, 1880 = 20 

 I days. 



The caterpillar suspends itself by the tail to undergo 

 pupation. The chrysalis is a very remarkable one, being 

 covered with long excrescences, four of which on the back of 

 the thorax are arranged in the form of a cross. It is also 

 remarkable for the faculty of making a squeaking noise when 

 annoyed. This is done by violent jerks of the abdominal 

 rings, the sliding of one ring over the other causing the 

 noise. The sound is very like that made by the Longicorn 

 beetles.
