NOTES ON RHOPALOCERA, WITH DESCRIPTIONS OF NEW 



SPECIES AND VARIETIES. 



BY HENRY SKINNER, M. D., PHILADELPHIA, PA. 



I have received beautifully fresh specimens of Argyrmis atossa taken 

 in the mountains near Tehachapi, Southern California, July 7th, 1895. 

 The inner half of the superiors below is bright red, almost a blood red. 

 The species was described by Mr. Edwards from a specimen taken by Mr. 

 H. K. Burrison. It is quite distinct and ranks with diatia, idalia and 

 nokomis as one of our handsomest Argynnids. 



Argynnis Snyderi, n. sp. — (^ . Expands three inches. Upper side : 

 Superiors tawny as in other species, but dark and with considerable red. 

 The black markings are distinct and sharply defined against the tawny 

 background. The margin is distinctly but not heavily marked. The in- 

 feriors have the usual black markings, but they are unusually well defined 

 and there are almost no black scales at base as in most species in the genus. 

 Under side : Superiors have silver spots on outer margin, extending more 

 than half way toward inner margin. There are two quite large subapical 

 silver spots. On inferiors the silver spots are large and well defined, with 

 wing-ground very light grayish-green with a distinct light buff interme- 

 diate border about one-eighth inch in width. Silver lunules on margin are 

 large, well defined, and seven in number, the inner one extending up along 

 inner margin as a line. The ground colour of wings on inferiors below 

 is brownish in the female. This large species comes nearest coronis, and 

 has been mistaken for it. I have specimens from Salt Lake City, Utah, 

 taken June 23rd, 1895, and a female from Ogden, July 6th, 1895. All 

 were taken by Prof. A. J. Snyder, after whom the species has been named. 



Argynnis platina, n. sp. — ^. Expands two and a half inches. 

 Upper side : Rather light tawny or even light buff. Black markings dense 

 and wide, with outer halves of wings looking rather clear or open, with 

 row of round spots not very large ; marginal border light ; bases of wings 

 not much obscured. Under side : Superiors have the two subapical silver 

 spots and silver spots on margin well defined j colour of inner half of wing 

 rosy. Silver spots on inferiors are large and well defined and placed on 

 a very light greenish-gray ground. The intermediate buff band is well 

 defined, comparatively wide and very light in colour. Groundcolour on in- 

 feriors below is reddish brown in the female. Described from specimens 

 taken at Ogden, Utah, between July iSth and 24th, and Beaver Canon, 

 Idaho, at nearly same dates. From Prof. A. J. Snyder,
