I possess the chrysalis of P. ttirnus, ruttihis, dmuius, but there 

 is no possibiUty to ascertain differences of value after the com- 

 parison of one or two specimens. 



A gap is also for those species that the appendages of the 

 genitals are unknown. This gap can only be filled in a manner 

 to allow scientific conclusions when the appendages of P. turnus 

 are studied in many specimens, to begin with fresh or living ones. 

 Only after the extreme limits of variation for one species are 

 known, a scientific comparison with those of the other species will 

 be possible and will give reliable results. 



PARNASSIUS. 



Mr. Stretch collected one female July 23, in Colville Valley, 

 W. T,, between Little Spokane and Loon Lake where granite first 

 appears. A second specimen was seen. Exp. 65 mm. The 

 whole body below, the front and the thorax above and the ex- 

 treme base of the primaries were thickly covered with intensely 

 yellow hairs. The veins of the wings on the under side were 

 yellow, and also the membrane when the insect was fresh had a 

 decidedly yellow tinge. Species known with yellow hairs are 

 P. Eversvianni and its female {^P. tJior, as I am informed by Mr. 

 H. Edwards) and P. Nomion, Fischer. A detailed comparison 

 of the figures and descriptions of P. Eversmanni do not allow to 

 bring the female to this species. P. Nomion is much larger, but, 

 indeed, the marks and the pattern of the wings are very similar. 

 I have no female van Suiinthciis before me agreeing with the 

 female from Washington Territory. The excellent figures of Mr. 

 W. H. Edwards do not contain one exactly alike, pi. 2, f. 2, seems 

 to be the nearest to it. Mr. W. H. Edwards speaks of partial 

 covering of the body with dirty yellow hairs by P. smintheus, and 

 as the pouch differs not notably from this species, it will be con- 

 sidered better as an exaggerated variety of P. smintheus. 



Later, in W. Montana, August 7, I saw not far from the stage- 

 coach, before New Chicago, some specimens flying, with the ap- 

 pearance of larger males of P. smintJieus. 



NOTES ON ORGYIA LEUCOSTIGMA. 



By N. Coleman, Berlin, Conn. 



A few notes on the various changes observed during the 

 growth of the larvae of Orgyvia leucostigma, Smith, may not be 

 uninteresting to the readers of " Papilio." 



My attention was first directed to these changes in the sum- 

 mer of 1877, by finding some larva; differing in color from Harris' 

 description of this species. Harris describes the larvae as "of a 

 bright yellow color, sparingly clothed with fine yellow hairs on 

 ^he sides of the body, and having four short and thick brush-like
