scaling 15. Glaphyria. 



1. Fore wing with R, free from Rj (fig. 316), rarely short-stalked with R 3+4 . 

 2. With metallic scaling on margin of hind wing; maxillary palpi as long 



as third segment of labials \1 . Dicymolomia!

16. Lipocosma. 



15. GLAPHYRIA Hiibner 

 (Homopkysa Guenee) 



Characters of the subfamily. Palpi with slight projecting angles formed by the 

 vestiture of the first two joints, third joint obliquely upturned. Hind wing with 

 M 2 and M 3 approximate. Fore wing with apex rounded or marked. Maxillary 

 palpi always moderate in size, rough-scaled, and porrect. Fore wings with a 

 yellow or yellowish ground color, with two white transverse lines; the antemedial 

 line usually waved, the postmedial one denticulate, and both normally finely 

 dark-edged. 



Key to the species 



1. Antemedial space below costa, at least, and sometimes whole disc brown or

2. Basal sixth concolorous with antemedial space, or slightly paler at extreme 



base 6. peremptalis. 



1. Ground color ranging from straw to ochre yellow; without a darker ante- 

 medial area. 



2. -Outer half of fringe pure white 4. lentiflualis. 



2. Outer half of fringe only slightly paler. 



3. Fringe mixed fuscous and white, appearing striate in perfectly fresh 



specimens 3. psychicalis. 



3. Fringe evenly, or nearly evenly, ochre yellow, concolorous with win? or 



somewhat darker 2. sesquistrialis. 



3. Fringe cream-white 1. glaphyralis. 



1. G. glaphyralis Guenee. Lemon yellow, more or leas marked with cream-white: 

 sometimes cream-white with the yellow only defining the markings. Antemedial

 somewhat paler. Sometimes lightly shaded with pale brown. Hind wing similar

July and Augrust. Florida specimens are usually bright yellow; northern ones 

 mostly cream-white. 

 New York to Illinois and southward. New York: Otto. Ithaca. 



2. G. sesquistrialis Hiibner. Ochre-yellow; duller than G. glaphyralis. the lines 

 similar, distinctly defined with light brown, and the ground somewhat shaded with 

 light brown, but without whitish shades. A distinct broken black terminal line, 

 preceded by white dots; fringe ochre to light brown. 15-18 mm.

3. G. psvchicalis Hulst. Bright ochre yellow; lines very fine, normal, sometimes 

 partly defined with brown, and more or less broken; more wavy than in the last
