with white further on ; the basal joint is not swollen and the stalk is 

 simple ; the color of the thorax and fore wings is as in the preceding 

 species, but the reflections are more green and blue ; the hind wings are 

 dark fuscous, with a small white spot about midway of the dorsal margin. 

 The abdomen is narrow and pointed and of a rich brown hue. At. ex.

A. flammeitsdla, % . N. sp. 



A single specimen with both antennae broken off near the base. The 

 basal joint of the antennae is not incisorate, and my notes made when the 

 specimen was received say that the antennae are black annulate with 

 white. The palpi also are gone. The head is clothed with saffron yellow 

 hairs as in the preceding species, and the body, the basal joints of the 

 legs and the fore wings are rich greenish brown, varying with the light to 

 purple, bronzy green or golden ; by gas light it appears bright golden and 

 with the wings closed looks like a minute brilliant flame, whence the 

 specific name. The fore wings have no markings except a minute whitish 

 spot at the beginning of the costal ciliae, which is also visible on the 

 under side of the wing. It is a little smaller than either of the two pre- 

 ceding species, and like them was received from Mr. Behrens.

S. argentinotella. N. sp. 



Face and palpi pale stramineous, except the outer surface of the 

 second joint of the palpi, which is black. Vertex, upper surface of the 

 thorax and base of the wings of a rich black, the black of the base of the 

 wings passing back along the fold and about the middle of the wing 

 length, spreading gradually over the entire wing, but becoming more 

 brownish and strongly bronzed. The costal and dorsal parts of the 

 wing, where the black is confined mainly to the fold, are suffused with 

 silvery white on a brown ground, which it almost obscures, and the white 

 scales pass backwards into the bronzed brown parts of the wing behind 

 the middle ; and there is also a patch of suffused white at the base of the 

 dorsal ciliae before the apex ; the bronzed brown becomes deeper from 

 the middle of the wing length backwards, and the apex is nearly black. 

 There are two silvery spots at the end of the cell and six silvery costal 

 streaks, or more properly, seven, but the first is on the extreme costa and 

 seems to form part of the suffused white of that part of the wing ; the
