In conclusion, I trust it will not appear to be an act of pre- 
sumption on my part to attempt to criticise the work of the 
eminent naturalist whose loss we must all deplore. I am well 
aware that an amateur naturalist like myself has not the 
opportunity of making the extensive and careful researches 
which have made the writings of our prominent scientists such 
magnificent records of devotion to their work. 
The remarks I have here ventured to make are merely the 
expression of the thoughts which have occurred to me in a 
humble endeavour to arrive at sound conclusions on a most 
complicated, difficult, and deeply interesting subject. 
For some years I have been making a special study of the 
most interesting forms of mimetic resemblance, more particu- 
larly amongst the African Rhopalocera, and I have invariably 
been much touched by the ready assistance which has been 
afforded me even by those prominent workers with whom I 
am acquainted only by correspondence, and it will always 
be my desire to reciprocate in every way which lies in my 
power. It is therefore with these thoughts in my mind that 
I should wish my remarks on Professor Packard’s paper to be 
regarded in the light of a friendly discussion on a subject of 
mutual interest, and not in any way a criticism of the personal 
views of a naturalist whose work must ever command the 
respect, both of those whose attainments entitle them to 
rank with him in eminence, and also of those who, like 
myself, are of the humbler, though I trust not less faithful 
workers. 
Finally, I would gratefully acknowledge the help I have 
received from Professor Poulton, who has very kindly fur- 
nished me with references and data which have been of great 
assistance in the preparation of the foregoing remarks.

Pierines, are in the habit of congregating in large numbers on
