Tincina of the Central United States. 119 



I think that if one .could ever get rid of its prismatic resplendence, its true 

 color would be best described as bright silver, tinged with gold, except 

 the basal half of the costal margin, and the large spot at the base of the 

 cilia, before mentioned, the true color of which are a rich purple black. 

 Al. ex., one fourth inch. Two specimens captured May 23d, under 

 hackberry trees (^C'tltis occidentalis). 



N. uni/ascicUa (n. sp.) 



Palpi, legs, under surface of the thorax and abdomen, upper surface 

 of thorax and basal two thirds of the upper surface of the wings 

 shining black, with a brilliant metallic luster, like polished steel or silver, 

 so that a silvery white, rather wide, fascia, placed, at the apical third of 

 the wings, is scarcely distinguishable in some lights from the remainder 

 of the wing ; this fascia is nearly straight, and the wing behind it and 

 the fringes are deep purple black, and the costal nmrgin, from the base 

 to the fascia, also shows the purple gloss. Under surface of the wings 

 deep black ; antennjB black ; head and face rufous ; eye-caps silvery 

 white. The scales ai'e fine and smooth, and it is no mean competitor 

 of the preceding species as to beauty. Al. ex., three sixteenths inch, 

 Kentucky. 



BuccuLATRix — B. anibrosicefoliella (n. sp.) 



Face white ; eye-caps white ; antennae with alternate annulations of 

 ■white and dark brown ; vertex wdiite, stained with ocherous brown : 

 thorax ocherous yellow, faintly sprinkled with brown. The ground 

 color of the fore wings seems to be white, but it is so much overlaid 

 with pale ocherous that the white is only distinct in a few places; thus, 

 the basal portion along the costa, for nearly one third of the wing length, 

 is whitish, faintly sprinkled with pale ocherous and brown ; and there is 

 a distinct, curved, white streak, forming an arc of a circle, beginning on 

 the dorsal margin, just before the middle, and curving back to the dor- 

 sal margin, just behind the middle, and margined toward the dorsal 

 margin of the wing (that is, within the arc) by black scales ; the scales 

 between this black internal edging of the arc and the costal margin 

 are ocherous ; the extreme costa, near the base, is dusted with dark 

 brown, which ends just before the middle in a short, oblique, brown 

 streak ; there are also scattered blackish scales along the dorsal margin, 

 near the base. About the middle of tlie costal margin begins a long, 

 dark brown streak, which passes obliquely across the wing, to the hinder
