Mexican and Central-American specimens of this species all have the distinct yellow 

 patch at the anal angle and the neighbouring portion of the outer margin. This form 

 also extends through Venezuela, Colombia, and thence southwards to South-eastern 

 Brazil and Paraguay. In the Valley of the Upper Amazons this yellow patch becomes 

 more contracted, and in the Lower Amazons region, and no doubt Guiana, it disappears 

 altogether, the secondaries being nearly uniform throughout. 



Cramer figures both forms, of which he considers the one with yellow on the second- 

 aries to be the male. This view is not correct, for we find no difference between the 

 sexes in this respect. 



The question of the specific distinction of these forms is not raised by that found 

 in our country, which agrees with Cramer's fig. C, and may be called E. busirus. 

 Fabricius's Papilio sebaldus refers to the same form. 



Fantis busirus is a very common species in Central America, and occurs more 

 sparingly in Southern Mexico on both sides of the mountain-range. It is a species of 

 the hot country, with a range in altitude probably not exceeding 3000 or 4000 feet. 



The male genitalia have a tegumen ending in a strong central truncate rod, slightly 

 hooked ; at its base are two erect rods, one on either side, slightly curved forwards. The 

 scaphium is well developed, and the harpes end in a rounded lobe, the dorsal edge of 

 which is strongly serrate; near the middle of the dorsal edge, where there is a fissure, is 

 a small subsidiary lobe, serrate and dependent on the right harpe, smooth and erect 

 on the left. (See Tab. LXXXVII. fig. 6.)

Alis brunneo-nigricantibus, fusco irregulariter plagiatis, fascia submarginali squamis caerulescentibus composita,
