THE CANADIAN ENTOMOLOGIST. 123 



well if we accordingly restricted Smerinthus to the Californian species and 

 separated our Eastern forms under Eusmerinthus and Calasymbolus. I 

 used Faojiias for Excaecatus, which differs by the scalloped wings. Also 

 Cressonia iox juglandis, correcting Dr. Clemens' notion as to the European 

 Populi, which represents neither juglandis nor modesta, though nearer 

 the latter. Cressonia is as distinct a genus as we have in the whole 

 family. Triptogon is largely represented in Asia. I follow now with the 

 Sphinginae, which enter the ground to pupate, commencing with Ceratomia, 

 which in its larva approaches Triptogon and is a peculiar American form. 

 I follow then with Daremma, Diludia, Pseudosphinx (= Macrosila 

 Butler), Amp/i07iyx, Phlegethontius, JDolba, Sphinx ( = Zet/iia), Dilo- 

 pho?wta, Hyloiacs, Ellema, Exedrium. I do not believe these latter to 

 be Smerinthinse, but low borabycoid Sphinginte. This 'group feeds 

 especially on the Solanacege, also Convolvulus and Privet. The tongue 

 is often attached, like a jug handle, as Prof Fernald says, to the pupa, 

 which reposes in a naked cell under ground, the larva rolling the soil 

 about it compact. I am glad Prof Fernald uses Phlegethontius, which 

 has priority and is a clean genus against which nothing can be said. If 

 we study these insects carefully, I am sure we will finally accept all the 

 genera, or nearly all, I have proposed. It is unwise to lose sight of the 

 very clear characters which have been so well discussed by Prof Fernald 

 so far as his very readable pamphlet goes. I think when the extra-limital 

 and especially South American forms are studied by the Professor, he 

 may incline to place the Sphinginae where I have placed them. I have 

 been guided by their subterraneous pupation, their gray colors like the 

 lower moths. The Macroglossians and the Choerocampians are gayer 

 colored, day loving, active species. How often have I not taken Lineata, 

 and also Pandorus, at midday. I am glad to see that my use of Pa/i- 

 dorus, which was made after careful comparison with the true Satellitia 

 of Linne', is being sanctioned. The reading of Prof Fernald's pamphlet 

 has given me great pleasure, and I should be affected and ungrateful not 

 to acknowledge it. But it will have, with all that this author has given us 

 that I have yet seen, a far more important value than the mere vindication 

 of this or that name in our lists. It will show how much there is yet for 

 us to learn about our moths, and also the way to learn it.
