«0 SMERINTHUS CERISYT. 



Mr. Grote moiitioiirt (Iiat Mr. Stpli. Calvcrly of X. York, (of whom wc have licanl nothing ior .some 

 yoar.s,) once informed him tiiat lie had raised this spceics from flie larva; but as there is no record of tlio par- 

 ticuhirs of so interesting an event, we may be pardoned for suggesting that perhaps Mr. C. may i)ossii)Iv have 

 been mistaken in tlic species, wliich, of course, can yet be determined if his examples an- still extant. ' 



SMERINTHUS MODESTA. Harris. 

 Cat. X. Am. Sphingidae, Sill. Jul. Art & Sc, Vol. 'M. p. •2'.*2, (1S39.) 



(PLATE VII, FKi. 11, :j\) 



Male and Fk.mai.i;. KxpanJ 4 to 5 inches. 



Head and body pale grey. 



Upper surface : i)rimaries, basal third very pale grey, with taint transverse .shades ; .i broad olivaceous 

 median band, within which is a small white disail spot; adjoining this is a pale transverse shade and a narrow 

 undulate band ; the space from these to the e.xterior margin is olivaceous. Secondaries duskv rose-color ; 

 costal and abdominal margins very pale grey ; exterior marg-in olivaceous ; near the anal angle is a bluish <r\\-Y 

 patch surinounte<l 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. A^ery 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 ease with his generation, but in our day it is precisely the reverse. ' Wc 

 may, however, have yct^ to fall back on Walker's more appropriate name of Princeps. for should Dentatus, 

 Cram.,* and ^Nlodesta, Fabr.,t 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

 (PLATE VII, FIG. 10.) 



Same size as S. Populi. Head and body brown, ground color of i)rimarics pinkish, same a« S Occllata • 

 markings brown, and same style as in S. Populi. Secondaries brown, with a reddish basal i)atch • an obscure 

 grey .spot replaces the ocellus near the anal angle. ' 



Under stu-face is a complete compound of the colors and markings of both Occllata and Poi.uli favorino- 

 however, the iormcr the most. ' "' 



This monstrosity, an oflenee against nature and local collectors, is, nevertheless, as :irenctries sav- at all 

 events very remarkable,! and, although not of our fauna, I have fis>ured it as a curiositv, as well asVor its 

 affording an illustration of the close affinity of the Smerinthid species^with each other, for fh'erc can .scarce be 

 any species more unlike in appearance than the European S. Occllata and S. Po])uli, of which this abnormilv 

 IS the product.
