 W. Slossonia, n. sp. 



Expanse of wings, 15 mm. Head, palpi, antennae and thorax dark 

 brown, with metallic reflection in certain lights. Fore wings dark brown, 

 with a straight band across the middle, on each side of which a consider- 

 able portion of the wing is abundantly sprinkled with whitish scales, 

 which are arranged into very fine cross lines near the band, but more 

 irregularly toward the outer edge, which is more oblique than the outer 

 margin of the wing. The basal and outer portion of the wing beyond the 

 white sprinkled area, and the cross band except a black edge on each 

 side, are changeable in colour when seen at different oblique angles, from 

 deep violet to bright metallic red or flame colour, or golden yellow ; in 

 fact, the play of colours under a lens is quite remarkable. Fringe at the 

 base concolorous with the adjacent part of the wing, dark fuscous on the 

 outer part. Hind wings and abdomen above and beneath, and the 

 under side of the fore wings, dark fuscous brown. Legs dark fuscous 

 brown, with the first three segments of all the tarsi white at the base. 



Collected at Biscayne Bay, Florida, by Mrs. Anna T. Slosson, for 

 whom I take very great pleasure in naming this insect.
