while one of onr females (M(5rida) is almost as pale as P. imh-a ; tlie last sjiot of 

 the band is uearly always mnch longer than the jiatch M- — SM-. The base of the 

 hindwing is in most individuals black as far as SC- or a little beyond, but in 

 many specimens the black basal area is much restricted, having practically 

 disappeared iu a few individuals. On the underside the basal area of the hind- 

 wing is more or less washed out distally, the black scaling being in a largo 

 percentage of the specimens restricted to the extreme base or being altogether 

 absent ; sometimes the forewing is also much shaded with cream-colour. The 

 abdomen bears often a broad yellow lateral stripe, with which the dorso-lateral 

 dots are more or less merged together. The postmedian cell-bar of the forewing 

 is often more or less distinct on the underside. 



The figures in Edwards, Butt. N. Amer., I.e., represent average specimens of 

 this form ; figs. 1 and 2 agree perfectly with typical Bogota specimens. We do 

 not believe the original of these figures came from Arizona. If the specimen had 

 been a straggler from the south, one would expect it to belong to the Central 

 American form, which it does not. Some mistake in labelling is, we think, the 

 true explanation of the record of americus from Arizona. 



b'. f. iiiclasina nov. Yellow discal baud of forewing reduced on both wings 



to a row of spots which are shading off proximally ; bar on cross-veins of forewing 

 present. The band rather broader on underside, but never entering cell of hindwing, 

 more sharply defined on both wings than above, but occasionally gradually shading 

 off jiroximally ; the basal half of the hindwing rarely washed with buft'. 



These black individuals resemble the dark Mexican form asterioides of 

 P. poltjxenes asterius ; however, the forewing is proportionally broader, the discal 

 sjiots are powdered over with black proximally, the discocellnlar bar is present, 

 the tail is shorter, etc. 



This form appears to occur more frequently in the C'anca valley (probably at 

 high altitudes) than anywhere else. Type of name from Pereira, Cauca valley. 

 Strecker, I.e., figured as P. asterioides Eeak. a female of this form, said to be from 

 Costa Rica. It is not impossible that a melanotic form occurs in that country, 

 but we cannot accept Strecker's statement without further evidence. Mistakes as 

 to locality occur easily, and we know for certain that at least in one case among 

 Papilios Strecker gave a wrong locality, his I', cleombrotus being erroneously stated 

 to have come from the Amazons. 



Hab. of P. jjobjxenes americus : North Peru to Colombia and Venezuela. 

 The type of americus came doubtless from the Cordillera of Bogota, which 

 Sulkowsky traversed on his way from the R. Magdalena to the Orinoco, going by 

 the R. Meta.
