INTRODUCTORY NOTE. 



The following paper, read before the Literary and 

 Philosophical Society of Liverpool, April 30th, 1883,* is a 

 continuation of the one communicated to that Society in 

 November, 1881, and is a description of the metamorphoses 

 of twenty-eight species of Brazilian Lepidoptera, illustrated 

 by specimens, which specimens I have had very great 

 pleasure in presenting to the Liverpool Free Public Museum. 



I regret that this series is not so complete as the former 

 one ; in many eases the larva or pupa is wanting, either 

 from the fact that I only found one specimen of the larva, 

 and so was not able to preserve the insect in the three 

 stages, or from my having mislaid some of the pupae on 

 leaving San Paulo. For, unfortunately, I find several pupae 

 that I thought I had with me are missing. However, on 

 consulting Mr. T. J. Moore, the Curator of the Museum, as 

 to whether I should describe only those species that I have 

 in all three stages, and leave the others until completed at 

 some future date, he replied, " A bird in the hand is worth 

 two in the bush ; " and on that principle I have given the 

 descriptions of some species whose life-history I have really 

 worked out, but which are not yet represented in the collec- 

 tion by examples of each state, hoping to have at some future 

 time the good fortune of obtaining specimens to make each 

 species complete. 



The critical determination of the species contained in 

 this second collection, as in the first, has, at the recom- 

 mendation of the Rev. H. H. Higgins, been intrusted by the 

 Library and Museum Committee to Mr. Frederic Moore.
