odours, at the end of the abdomen of various other male 

 moths, of which I do not know the names. 



Pencils or tufts of hairs appear to be of rather frequent 

 occurrence on the legs of male moths, e.g., among the 

 JErebidce and Geometridce, and in two or three cases odours 

 were observed to issue from them. 



In one of our largest Erehidce the tibiae of the hind legs 

 are much dilated in the male, and densely covered with 

 peculiar hairs, capable of being voluntarily erected ; they 

 emit a faint but distinct odour. 



As I know as yet but a very insignificant part of our 

 moths, a vast number of other odoriferous contrivances 

 may be expected to be found among the extremely 

 numerous species of these insects. 



Sou7ids made hy Butterflies.* 



I know here four species of Ageronia{Feronia, Fornax, 

 Amjjhinome waA. Aret]iusa\ nR of ^\\{lch. are rather com- 

 mon in certain localities where their food-plants {Dales- 

 ham-pia) abound. I have frequently heard the noise made 

 by them and can fully confirm Mr. Darwin's statement, 

 that this noise is produced, almost exclusively, when two 

 are chasing each other. Sometimes a short, clicking 

 noise is made, when an Ageronia is caught in the net. 

 On October 30th, 1876, at the mouth of the Rio Trom- 

 budo, a tributary of the Itajahy, I saw two butterflies 

 chasing each other, which produced a loud clicking noise, 

 and settled from time to time in the manner of Ageronia, 

 with the wings expanded horizontally, on dry stems of 

 Tagnara (bamboo). I, of course, imagined them to be 

 some species of Ageronia, but after having succeeded in 

 catching one of them, found that it Avas Eunica Margarita. 

 I may observe that the neuration of the wings of that 

 butterfly bears a rather close resemblance to that of 

 Ageronia, so that, indeed, it may be more nearly allied to 

 that genus than is generally assumed. 



On February 21st, 1877, at the foot of the Serra de 

 Itajahy, I heard a noise resembling that of Ageronia, but
