 Head and thorax above pale yellow, interspersed with a few black hairs. Lat- 

 erally the orbits of the eyes and palpi black, the latter yellowish beneath. Ab- 

 domen black, with the first segment above and the side tufts ou the last segment 

 but one pale yellow ; under side of the body and legs black. Primaries blackish, 

 with a pale or whitish oblique band across the wing beyond the cell and crossed 

 by the black veins. Discal spot small and black. Hind wings black, with a 

 broad central band of bright orange yellow. Beneath the maculation of upper 

 side reproduced, but paler, and the basal part of the primaries i.s bright orange 

 yellow. Expands 1.60— 1.75 inches; 40 — 46 mm. 



Hah. — Hudson's Bay Territoi-y, Canada, Maine, Massachusetts. 



The specimens seen by inc vary in the direction of a narrower 

 basal paler transverse band on primaries. The species is extremely 

 rare and flies in mid-day around flowers in June. Prof. Fernald 

 says it appears to be one of their earliest day flying Sphinges. Few 

 collections have more than one or two specimens of this species, and 

 I have been unable to obtain any for di.ssection. 



Nothing ii? known of the early stages.

"Male. Expands \i inches. Head above sulphur yellow, below black, an- 

 tenniB black. Thorax on back black mixed sjiaringly with yellow hairs, patagife 

 sulphur yellow, collar intense velvety black ; beneath black; legs black. Abdo- 

 men above velvety black with sulphur yellow side tufts to the last two segments, 

 anal brush black above, yellow beneath ; underside of abdomen black. Upper 

 surface of all wings blackish, darkest on basal half and at abdominal margin of 

 secondaries; a common broad, semi-diaphanous band a shade or so paler than 

 ground color crosses both wings, this band on the secondaries does not extend to 

 inner margin and shows toward its inner extremity a few scattered, scarcely 

 noticeable yellow scales. Under surface as above, dark color more dull ; some 

 loose orange hairs on basal part of primaries and the inner termination of tlje 

 mesial band of secondaries is slightly clothed with sulphur colored scales." 



"One % from Oregon. 



" This beautiful species is near to M. fluvofamcda Barnston, hut 

 differs n()tal)lv in the black collar and thorax, in the absence of the 

 bright yellow mesial band of .secondaries, as well as in its greater 

 size." 



Mr. Strecker's figure shows a remarkable species, entirely unlike 

 anything thus for known to \\\q. The figure exi)ands nearly two
