SMERIXTHUS CERISY1 . 
Mr. Grote mentions that Mr. Stpli. Calverly of X. York, (of whom we have heard nothing for some 
years,) once informed him that he had raised this species from the larva; but as there is no record of the par- 
ticulars of so interesting an event, we may be pardoned for suggesting that perhaps Mr. C. may possibly have 
been mistaken in the species, which, of course, can yet be determined if his examples are still extant.

Male axd Female. Expand 4 to 5 inches. 
Head and body pale grey. 
Upper surface ; primaries, basal third very pale grey, with faint transverse shades ; abroad olivaceous 
median band, within which is a small white discal spot ; adjoining this is a pale transverse shade, and a narrow 
undulate band; the space from these to the exterior margin is olivaceous. Secondaries dusky rose-color ; 
costal and abdominal margins very pale grey ; exterior margin olivaceous ; near the anal angle is a bluish grey 
patch surmounted by a curved black streak. 
Under surface ; pale olivaceous grey, broadly margined exteriorly with a somewhat darker shade ; base of 
primaries dusky rose-color, on which the pale discal spot is visible. 
The larva feeds on the Lombardy Poplar (P. Dilatata). 
Habitat. Canada, Lake Superior Region, New England and Middle States. Very rare. 
One can scarcely understand why Dr. Harris should have designated this noble species, the prince of its 
genus, by so humble an appellation, unless he labored under the fallacious idea that greatness and modesty are 
inseparable, which may have been the case with his generation, but in our day it is precisely the reverse. We 
may, however, have yet to fall back on Walker’s more appropriate name of Princeps, for should Dentatus, 
Cram.,* and Modesta, Fabr.,f be eventually determined as distinct from each other, of which there is every 
probability, then Harris’ name will long have been preoccupied, and Walker’s would have to be retained in its 
place*

HIBRIDA EX S. OCELLATA ET S. POPFLI. 
(PLATE VII, FIG. 15.) 
Same size as S. Populi. Head and body brown, ground color of primaries pinkish, same as S. Ocellata ; 
markings brown, and same style as in S. Populi. Secondaries brown, with a reddish basal patch ; an obscure 
grey spot replaces the ocellus near the anal angle. 
Under surface is a complete compound of the colors and markings of both Ocellata and Populi, favorino- 
however, the former the most. 
This monstrosity, an offence against nature and local collectors, is, nevertheless, as Menetries says, at all 
events very remarkable, £ and, although not of our fauna, I have figured it as a curiosity, as well as for its 
affording an illustration of the close affinity of the Smerinthid species with each other, for there can scarce be 
any species more unlike in appearance than the European S. Ocellata and S. Populi, of which this abnormity 
is the product.
