Genus Papilio 



(2) Parnassius smintheus, Doubleday and Hewitson, Plate 

 XXXIX, Fig. 3, $ ; Fig. 4, ? ; var. behri, Edwards, Fig. 1, 8 ; 

 Fig. 2, 9 ; var. hermodur, Henry Edwards, Fig. 6, $ ; mate of 

 hermodur, Fig. 5, 6 (Smintheus). 



Butterfly. — This very beautiful insect is greatly subject to va- 

 riation, and the plate shows a few of the more striking forms, 

 of which the dark female, named hermodur by the late Henry 

 Edwards, is one of the most beautiful. Expanse, $, 2.00-2.50 

 inches; ?, 2.25-3.00 inches. 



Smintheus is found at proper elevations upon the mountains 

 from Colorado to California, and from New Mexico to Montana. 

 The life-history is most exquisitely delineated by Edwards in 

 "The Butterflies of North America," vol. iii. 



The caterpillar feeds on Sedum and Saxifraga. 



Genus PAPILIO, Linnaeus 

 (The Swallowtails) 



" The butterfly the ancient Grecians made 

 The soul's fair emblem, and its only name — 

 But of the soul, escaped the slavish trade 

 Of mortal life! For in this earthly frame 

 Ours is the reptile's lot — ■ much toil, much blame, — 

 Manifold motions making little speed, 

 And to deform and kill the things whereon we feed." 



Coleridge. 



Butterfly. — Generally large, frequently with the hind wings 

 tailed. A figure of the neuration characteristic of this genus is 

 given on p. 20, Fig. 38. From this it will be seen that the in- 

 ternal vein of the hind wing is lacking, the submedian vein oc- 

 cupying the space which is commonly occupied by the internal 

 vein. The median vein of the fore wing is connected with the 

 submedian by a short vein, from the point of union of which with 

 the submedian there proceeds a short internal vein in this wing. 

 There is great diversity of form in the wings of this genus, some 

 species even mimicking the species of the Euploeince and Heliconi- 

 idce very closely, and being entirely without tails. In all cases, 

 however, in spite of obvious diversities in color and in form, 

 there is substantial anatomical agreement in the structure 01 the 

 wings; and the caterpillars and chrysalids reveal very strongly
