4. Parnassius Smintheus Doubl., var, Hermodur, H. Edw. 



Mr. Edwards describes this form in Papilio, i, 4, from a female in 

 collection of the late Dr. James Bailey, and taken in southern 

 Colorado. This expanded 2.3 inches. He compares it with 

 P. Corybas, Fisch., from the Altai, an example of which in his collec- 

 tion measures 2.65 inches. These Montana examples, of both sexes, 

 are very large, considerably beyond the average of Smintheus from 

 Colorado, some males and females reaching 2.7 inches. Several of the 

 females are very black, there being but little of the yellow-white 

 ground left, and that principally in cells of primaries and on disks of 

 secondaries. Others have the yellow-white over most of secondaries, 

 and in cell and next base of primaries, but the outer half of primaries 

 is melanic and transparent, with only a submarginal row of yellow 

 spots on that area. The red spots are of extraordinary size. I should 

 have taken the female for a distirtct species had not the male been so 

 like, and often undistinguishable from, the Colorado males of Smin- 

 theus, though, as before said, larger. Some of them have the spots 

 orange, as in var. Behrii. Several of both sexes I cannot distinguish 

 from a pair of P. Intennedius, sent me by Dr. Staudinger, as Menetries' 

 species, from Siberia. These are the examples in which there is an 

 absence of melanism, and the marginal borders of both wings are 

 transparent. I have a 5 of this same form, taken on Mt. Bradley, Cali- 

 fornia, by Mr. James Behrens. 



Mr. Courtis, at my suggestion, shut up some of the females with 

 Sedum, on which Smintheus has been known to lay, and ob- 

 tained 140 eggs, all which I have now in an ice-box, hoping to carry 

 them through the winter, and to hatch them at the time I can get 

 plants of Sedum here. Mr. Courtis says : " Most of these eggs came 

 from females that mated after I caught them. The others would not 

 lay, although I kept them shut up with several males until they nearly 

 starved." (The first instance I remember to have heard of, in which 

 butterflies have mated in captivity.) "The virgin females seemed to 

 have the end of abdomen of a light greeti horn, instead of black, 

 but after mating I noticed they turned black. I think they lay 

 on the roots of plants,' as the females always drop to the ground, 

 climb up a stalk and fly away. Those in confinement climbed sticks 

 and window frames, laying eggs as they went. They curved their 

 bodies round and put an &gg on whatever they touched ^.rr^/ ///,? 

 Sedum. I made one lay on it by keeping her moving from one piece 

 to another, but she seemed much excited, and as soon as I put her on 

 grass and sticks she laid every few minutes." In a later letter, 5th 

 Aug., Mr. Courtis writes : " I noticed a female Parnassius alight on a 

 piece of Sedum, drop to the ground, climb up and lay an Qgg either 

 in the kaves or the roots or on the ground. I could not find the &gg, 

 and yet I saw her go through the motion of laying. The only ones
