the first of which is to the genus we are considering. His first 

 species is "Hemiargus bubastus Hiibn. Zutr. 99-100." These 

 figures are on plate 509, and the legend at the bottom of the 

 plate is "99-100 Hemiargus antibubastus." 



In Hiibner's and Geyer's text belonging to this volume, the 

 species and plate are referred to as "Hemiargus antibubastus, 

 Zutr. I, figs. 99-100,'' and the preface to this part I of the 

 Zutrage is dated 22-XII-i8i8, so that it is evident that if it did 

 not appear before the end of 1818 it must have appeared 

 early in 1819; in addition to other references there is on 

 p. 74 of the V 'erseichniss No. "73 Lycus niphon, Zutrage 203- 

 204," which plate was issued in Part II of that work, the 

 preface to that part being dated 23-XII-i822, whilst the 

 Title is dated 1823. These references prove that the Ver- 

 seichniss could not have been issued before the end of the 

 year 1822, therefore Hemiargus bubastus (1822) falls as a 

 synonym to Hcmiargus antibubastus (1818) if it should happen 

 to be the same species. The genus Hemiargus was at its institu- 

 tion a monotypical genus, containing only antibubastus. This 

 species, therefore, is its type, and as a consequence Scudder 

 was acting ultra vires in selecting Jianno as type. We get, 

 therefore : 



Hemiargus Hitbner, monotypical genus, type antibubastus. 



Returning now to Dyar's list, his first species is 



H. isola Reakirt. 



The genitalia of this species are extraordinary in that there 

 is a large toothed hood above the furca, occupying an interme- 

 diate space between the tegumen and cingulum and the har- 

 pagines ; it has its origin just above the very short furca; the 

 aedoeagus is also different somewhat to the others of the 

 genus, but in other characters the species would appear to be 

 rightly placed in this genus.

This species has nothing to do with isola; it has two dis- 

 tinct anal spots with metallic edging in the hind wings and 

 therefore belongs to the catilina group ; it will be referred to
