I use this name as a generic name, following the example of Mr. 

 Ragonot in some of his diagnoses of the PhycilidiE, and as well my own 

 previous custom. It seems to me as appropriate under any circum- 

 stances to give insects the names of our N. A. Indian Tribes, as to give 

 them the names of the ancient tribes and cities of Greece or Rome, and 

 far more appropriate in case of N. A. Insects. And it also seems to me to 

 be at least as aj)propriate to give these, as to give sesquipedalian polysyl- 

 labics, manufactured from words which the Greeks ought to have had in 

 their language, if, as in many instances, they did not. It seems a 

 pleasant fancy to see the spiiits of the ancient dwellers of the American 

 forests and plains still wandering in "night's shades,"' in the moths, the 

 phantoms of the forest, mountain, and glen. 



The armature of the hind tibix of this genus is remarkable, and at 

 the writing of what was published last month had not yet been noticed. 

 ^ly number of specimens is small, and I can not further verify my ob- 

 servations, and I would hardly assert the facts were it not that in Caco- 

 5^//rt the u])per pair of spurs is almost obsolete, and in the next genus 

 Yiana the upper pair of spurs is certainly wanting.

Expands, 22 to 25 mm. Head and color yellowish brown, strongly washed with 

 violet. Palpi brownish gray or yellowish gray in front, strong, recurved over head, 

 scale tufted at end of second member, end member tine, distinct. Maxillary palpi very 

 small, the end member set on the side but near the summit of the member next below, 

 all invisible under ordinary observation. Ocelli very distinct. Antennal process 

 short. Front of head rather heavily scaled, collar also run in somewliat of a ridge. 

 Thorax dark fuscous. Abdomen light fuscous, the segments ringed with dark fuscous, 

 extremity tufted in rT with lateral tufts on 2 segments preceding anal segment. Fore 

 wings much rounded at apex, generally light even blue gray in color with a strong 

 shading of fuscous on basal and outer fields. A dark broken cross line close to base 

 not always distinct ; near the outer edge of the field a dark line consisting of length- 

 ened and raised scales, and extending quite across the wing. The line limiting the 

 field is very indistinct and is evidenced rather by its hardly distinct shade lines. Middle 

 field with three raised scale tufts, one discal small, the second extra-discal, more pro- 

 minent and lengthened, the latter shaded outwardly, with fuscous, and a third near 

 center of the field one-third from inner margin, black. Outer line quite distinct near 

 costa, becoming obsolete posteriorly, shaded as usual, this shading being broad and 

 diffuse near costa and outwardly occupying the whole apical space. The outer hne 

 forms a large sinus from the costa, and this with the shading and posterior obsoles-
