NATURE-STUDY REVIEW . [13:6— Sept., 1917 



ornamented with nearly thirty large silvery white spots. While in 

 general it resembles the great spangled fritillary and the silver-spot, 

 the black hind wings distinguish it from these species. 



The Great Spangled Fritillary 

 Expanse about three inches. Color orange (which fades to a 

 dull brown late in the season) marked with black, the wings 

 shading to brown next to the body. Undersides of the 

 wings of the Great Spangled at the left; of the Silver Spot 

 at the right. 



The Great Spangled Fritillary and the Silver Spot Fritillary. — 

 These two are of the same size and marked very similarly. The 

 only way to distinguish the two species is to study the lower side 

 of the hind wings ; in the great banded species there is a broad, buff 

 band inside the silver spots that border the wings ; it is one-fourth as 

 broad as the wing itself. This band is very much narrower in the 

 silver spot. The caterpillars of these species are velvety black and 

 spiny, and feed on the leaves of violets.
