Sphing. 19, Lepisesia; Grt., Hawk Moths 27, Lepisesia. 

 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 on 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 rejiroduced, but paler, and the basal part of the primaries is bright orange 

 yellow. Expands l.GO — 1.75 inches; 40 — 46 mm. 



Hab. — Hudson's Bay Territory, Canada, Maine, Massachusetts. 



Tlie specimens seen by nie 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 dissection. 



Nothing is known of the early stages.

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

 tennte black. Thorax on back black mixed sparingly with yellow hairs, patagise 

 suli)hur 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 the 

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



" One ■& from Oregon. 



" This beautiful species is near to 31. fiavofasciata Barnston, but 

 differs notably 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 far known to me. The figure expands nearly two
