83. XEONYMPHA GEMMA, Hub. 



Expanse of wings 1.25 inches. 



Upper surface gray, with a little wood-brown tint, no 

 marks except two darker shades near the middle of the 

 outer edge of the hind wing. 



Under side about the same color, sprinkled with buff 

 scales, the outer edge with a slight golden reflection. On 

 the fore wings are three not very distinct, wavy, brown, 

 transverse lines. On the middle of the outer surface of 

 the hind wings is a large oval patch composed of white 

 and reddish-brown scales, giving the patch a slight violet 

 tint when seen without a glas>. In the outer edge of 

 this patch, standing on the iutervenular spaces, are four 

 roundish, vandyke-brown spots, on each an anchor-shaped 

 spot of pale, metallic, bluish scales. The margin of the 

 wing towards the apex and anal angle has a border of 

 metallic, bluish scales, with dentations up the sides of the 

 veins. There are two brown lines on the hind wings, 

 besides a brown bordering to the terminal patch. 



The eggs are globular, seemingly smooth, but under 

 a high magnifying power are seen to be reticulated in 

 irregular hexagons, the ridges flat and broad, having at 

 the bottom of each depression a white point. Color yellow- 

 ish green. These are deposited on grass, and hatch in 

 from three to six days. 



The young larvae are .12 of an inch long, cylindrical, 

 a little thickest in the middle, ending in two divergent 

 tails, the point blunt and tipped with a white bristle. 

 Color white, with white scattering hairs, after a few days 

 changing to alternate stripes of white and green. Head 

 subpyriforni, one-half broader than the second segment,
