the age of objective research, as contrasted with that past in ob- 

 jectless complaint. Let us, then, see what we can while we live. 

 Let us mellow our lives to our Harvest time, that then, like a perfect 

 fruit, we may show in us the soil, the clew, the rain and the sun- 

 beam, and so fall at last good and sweet into the hands of the 

 Husbandman. 



Family SPHIXGIDAE. 



Genus Heniaris, Dalman (1816). 



It is Fabricins who, in 1793, arranges under the generic name 

 Sesia, a number of moths which have for a common character the 

 more or less pellucid wings. However, the moths thus early brought 

 together belonged to two distinct structural groups — families in the 

 Latreillean sense. In 1807, Fabricins restricts the term Sesia to 

 members of the family under present consideration — the Sphingidae, 

 and proposes the term Aegeria, for the group afterwards known, it 

 seems to me properly, as Aegeriidae by the English Entomologists. 

 This restriction is overlooked on the continent of Europe, where 

 the term Sesia has been generally, and I must believe incorrectly, 

 used as equivalent to Aegeria, Fair. But under the generic term 

 Sesia, in the Systema G-lossatorum (1807), Fabricins arranges a 

 nuniber of species, which are properly the types of distinct genera, 

 according to our present acceptation. Among these species is the 

 European fuciformis, for which the term Sesia has been retained 

 by English writers, and is used in 18Go by ourselves for congeneric 

 American forms. It is overlooked that Dalman has taken S. fuci- 

 formis as the type of his genus Hemaris, and that this name, having 

 priority over the subsequent restrictions of Fabricins' term, must be 

 retained for this type. 



I have elsewhere proposed to restrict Cephonodes, Hiiiner (1816), 

 to the Asiatic C.hylas; the type, so far as we can judge, of Hiibner's 

 genus ; certainly the first species enumerated in the " Verzeichniss " 

 under the name. Following Latreille's restriction, we must regard 

 the European Sphinx Stellatarum L., as the tvqje of Scopoli's genus
