PAPILIO DAUNUS Boisd. (Fig. 2, reduced.) 

 A male of this fine species, collected in Kansas near the Rocky Mount- 

 ains, is now in the Collection of the Entomological Society, presented by 

 Dr. T. B. Wilson. 



This species is described by Boisduval in his Spec. gen. p. 342, from 

 Mexico, and as I have never heard before of its occurrence north of the 

 Kio Clraude. it will not perhaps be uninteresting to point out here the dif- 

 ferences that exist between it and F. tvmns, with which it has a striking 

 resemblance. 



It differs from hirnus as follows: — The body is half again as large, and 

 the antennae are two lines longer than of any male specimen of turmts 

 Fig. 2. that I have examined. The primaries are long- 



er, more curved and narrower at the apex and 

 shaped more like P. tltoas; the posterior margin 

 of the secondaries is very deeply and acutely 

 dentated, and has three unequal tails of the fol- 

 lowing dimensions : the outer one is 9 lines long, 

 linear and curved inwards; the middle tail is 4: 

 lines long, straight; the innermost tail is 2 lines 

 long, broad and obtuse. The markings differ as 

 follows: the black dorsal line of the thorax is 

 narrower and does not widen posteriorly. There 

 is not so much black on the wings, the yellow of the upper side is deeper 

 and the yellowish crenulations of the posterior margin are almost obsolete; 

 the yellowish spots on the black marginal band are much larger, elon- 

 gate and merely separated by the nervures, those nearest the apex be- 

 ing broader; inside of this row of yellowish spots the black band is sur- 

 mounted with a distinct row of yellowish atoms; the four unequal black 

 bands proceeding from the costal margin, are situated as in tnrnus, but 

 the first or innermost one is narrow and tapers to the anal angle of the 

 secondaries, the second and third bands do not extend beyond the median 

 nervure, and the fourth is short and obsolete. The under side of the pri- 

 maries is the same as the upper side, except that the color is much light- 

 er, and the row of yellow spots on the posterior margin is broader and be- 

 comes a regular band. The upper side of the secondaries is marked as 

 in furnna, except that the fulvnus spot on the anterior angle is wanting in 

 this species. The under side has no fulvous spots except on the last 

 marginal lunule and the anal eye, the bluish atoms are very brilliant, and 

 the row of yellowish atoms very distinct. Expands nearly five inches.
