PAPILIO X. 



these 8pot,s fading out gradually on the Ijasal yide instead of Ijeing clear cut, and 

 on the outer side, nearly all on the primaries are concave. On the under side 

 there is an absence of the fulvous color which characterizes Astcrias, there being 

 at most a slight ochreous discoloration on the outer edges of the discal spots on 

 secondaries, and sometimes this is wholly wanting, or is restricted to the two or 

 three spots against cells. In fresh examples there is a belt of yellow scales inside 

 the sub-marginal spots. 



The female shows only traces of the band, sometimes limited to three or four 

 obsolescent spots on the upper part of primaries, or perhaps entirely across. In 

 one example these traces continue across secondaries, but in all others examined 

 they are absent. In all, however, there is a large spot of yellow, more or less 

 dense, on costal margin of secondaries. The spots of the sub-marginal rows of 

 same wings seem never to be distinct in the female, and often are represented by 

 a few scales only. In both sexes there is much variation in the extent of the 

 blue clusters on secondaries. On the under side in the female the band is always 

 distinct on secondaries. 



Aster las is also found in Arizona, and I have received several examples of 

 both sexes. They do not differ more from the northern form of the species 

 than individuals from one laying of eggs are found to differ in West Virginia. 

 Invariably they are characterized by deeji fulvous spots on inider side.
