114 Bulletin American Museum of Natural History [Vol. XLIII 



In preparing the following list I have acted upon the suggestion of 

 Mr. Lang to give a reference to the most easily accessible illustration of 

 each species. In a few cases no illustration has as yet been published, 

 in other cases the onh' illustration is in a recondite corner of the litera- 

 ture, antl I have not in some such instances taken the pains to cite the 

 figure, as the specialist interested in the subject will know as well as I 

 how to find such illustrations. I have constantly referred, in the case 

 of the butterflies, to the illustrations given by Aurivillius in Vol. XIII 

 of Seitz's 'Die Gross-Schmetterlinge der Erde.' This volume gives, for 

 the most part, very good figures of the Rhopalocera of the Ethiopian 

 region. The copy in my possession unfortunately is incomplete, its 

 publication apparently having been interrupted at the outbreak of the 

 war. At all events, since the fall of 1914 no parts of the book which was 

 being issued at Leipzig have come to hand.^ 



In no instance have I endeavored to give a complete synonymy 

 where a species has been frequently mentioned in the literature of the 

 subject. I have, however, endeavored in all cases to cite the original 

 description or figure of the species and have followed this by citation 

 of one of the latest references to that species, or of the subspecies, in 

 case a subspecific reference is called for. The student who desires to 

 explore the sjmonymy may consult among other works the 'Rhopalo- 

 cera yEthiopica ' of Dr. Aurivillius and the revisions published by Roth- 

 schild and Jordan in the 'Novitates Zoologicae' of the genera Charaxes, 

 Papilio, and the family Sphingidae. The synonymy of the Hesperiidse 

 published up to the year 1895 is given quite completely in my 'Synony- 

 mic Catalogue of the Hesperiidse of Africa,' and so forth (cf. Proc. 

 Zool. Soc. London, 1896) In studying the moths, reference should be 

 made to Sir George F. Hampson's 'Catalogue of the Phalsense' so far as 

 published. Assistance may be derived from Kirby's 'Catalogue of the 

 Lepidoptera-Heterocera,' but this work must be used with caution for, 

 although references to the literature are correct, many species have in 

 recent years been assigned to other genera than those under which Kirbj^ 

 listed them. In studying the Pyraustids and allied groups the writings 

 of Sir George F. Hampson must be consulted, and in studying the 

 Geometridae it is necessary to consult various papers published in recent 

 years by Warren, a number of which appeared in the 'Novitates Zoologi- 

 cae.' 



'The edition I have is that published in the German language between which and that published 

 in the English language there may be a few slight discrepancies in the pagination.
