APPENDIX. 



THE following list of Lepidoptera may be of use to collectors, 

 and is chiefly compiled from " Notes on Lepidoptera from the 

 Region of the Straits of Gibraltar," by James J. Walker, R.N., 

 F.L.S., published in the * Transactions of the Entomological 

 Society of London,' 1890,'pp. 361-391. 



Most of the Butterflies have been obtained by my son, L. P. 

 Irby, 60th Rifles, and myself; possibly a few more species may 

 be found. 



The list of Moths is incomplete, and is almost entirely from 

 Mr. Walker's paper, to whom I am much indebted for permission 

 to make use of his notes and for his kind assistance in looking 

 over this list. 



Those species marked with an asterisk occur on the Rock of 

 Gibraltar. All the Moorish specimens were found by Mr. Walker.
