A New Species of Argynnis from Utah 

 (Lepid., Rhop.). 



By Henry Skinner. 



Argynnis utahensis, n. sp. 



Upperside. Primaries dull fulvous with the extra discal rounded 

 spots as in Argynnis chitone except that the spots near the apex are 

 somewhat smaller than in that species and they are not so black and 

 well pronounced. The basal area of the wing is not nearly so dark as 

 in chitone. 



Secondaries are the same color as the primaries with the usual black 

 markings. The base of the wing is not obscured by dark scales as is 

 the case in some of the allied species. 



Underside. Primaries relatively light in color with two spots near 

 the apex and three of the submarginal lunules faintly silvered. 



Secondaries much as in chitone, but lighter in color with less black 

 around the silver spots. Some specimens are devoid of silver spots. 



The female is like the male, but slightly larger, and the base of the 

 primaries is much redder than in the male. 



This is the species that has always been confused with chitone Edw. 

 It can be readily differentiated by less black on the basal areas above 

 and below and by the generally lighter colors. 



The male expands 53 mm. and the female 55 mm. 



The type was taken by the writer in City Creek Canyon, 

 Salt Lake City, Utah, July 6th, and the allotype at Silver Lake, 

 Brightons, Utah, July I2th. There are nine paratypes from 

 City Creek Canyon, taken on the 4th to the 6th of July. Four- 

 teen specimens from Ogden, Utah, and four from Park City, 

 Utah, taken by A. J. Snyder in the first half of July. Three 

 specimens from Provo, Utah, taken by T. Spalding in July, 

 and four specimens from David Bruce labelled ''Utah." 



The types and other specimens are in the collection of The 

 Academy of Natural Sciences of Philadelphia. 



Costa Rican Butterflies (Lepid., Rhop.). 



On December 30th (1918) I took on the Cairo branch a female of 

 Hypolimnas viisippus, which may be a first record for Costa Rica. 



We have found larvae and reared them, on Hygrophila confnta 

 (Acanthaceae), of Amphircnc epaphus, though as this is so common 

 a species, it is unlikely to confine itself to that plant and probably 

 affects other species of the same family. The larva is very handsome, 

 velvety black with pale yellow bars at the segments, the chrysalis grass 

 green. — C. H. Lankester, Cartago, Costa Rica.
