niform large, upright, slightly constricted in the middle, concolorous, incompletely 
" marked with darker scales and often by paler yellowish white atoms. Secondaries 
' whitish, densely dark powdered, with a distinct blackish marginal line and a faint 
{ discal lunule. Beneath gray, powdery, primaries with disc darker, secondaries 
| paler, with an outer line and discal lunule. 
Expands 31 to 35 millimetres = 1.24 to 1.40 inches. 
HABITAT: Massachusetts, April 8 to 15; Missouri, April and May ; 
' Texas, February 17 to 26, 
Nine specimens, all males, and all save one from Texas (Belfrage in 
collection of C. V. R.), are before me. I have seen a number of other 
' specimens and there is very little variation save in the distinctness of 
‘the maculation. Asarule the punctiform s. t. line is quite distinct 
/and usually also the ordinary spots are evident. In fresh specimens 
| the metallic shining scales at base of thorax constitute an unfailing 
‘index to the species; but in old specimens or when they show even a 
|| slight tendency to grease, the metallic luster disappears, and the genus 
/as based on this character becomes irrecognizable.

“3. Fore tibie each with a long black claw; eyes naked; antenne testaceous, 
| bipectinate. Clear, bluish gray. Ornamentation of primaries feebly written. Or- 
|| bicular round, reniform narrow, curved, upright; the lines are double, and with the 
| spots indicated by pale brown shade lines, all concolorous with the wings. Thorax 
t shaggy, bluish gray. Hind wings whitish, a little soiled, with discal dot, faint 
i! terminal lines, and whitish fringe. Beneath white, with black discal spot and 
| broken black mesial line. Fore wings gray, with faint broad exterior shade line. 
|| Feet and abdomen gray. Expanse 34 millimetres.”

| This is a well-defined species most nearly related to rolandi, but 
larger, somewhat wider winged, a fine pale bluish gray in color, and 
| lacking all trace of the metallic scales.

This genus is distinguished from the others of the group by the thin 
| Jong hairy vestiture of thorax, forming no obvious tufts, by the brown- 
\!ish red or gray colors, the wings powdered with darker brown atoms 
‘and appearing more thinly scaled, and by the generally more bombycid 
habitus of the species. 
| Only one species was known for sixteen years, but I have now recog: 
nized four very distinct forms, separable as follows : 
Borealis, a new species, differs from all the others in color, the head, 
thorax and median space of primaries umber brown, the basal and
