Pig. 15, Parnassius clodius. 



Prof. R. A. Cooley, of the College of Agriculture and Mechanic Arts 

 at Bozeman, has sent us two specimens, male and female, of this species, 

 taken in Gallatin county, where he reports them rather abundant. The 

 pink and yellow spots are lacking on the primaries in both sexes. 



The male has more smoky brown on the outer edge and base of 

 primaries, with more translucent outer margin. The differences are more 

 clearly shown by comparison of Figs. 13 to 15. 



Distribution — Clodius is found upon the mountains of California. It 

 is reported from the state by Prof. Cooley as stated. Carrington and 

 Logan collected it on the expedition in 1871. 



Food — The capterpillar feeds on Sedum and Saxifraga.
