have been imported, either purposely or accidentally. The question is 
now, whether escudi breeds with us, as for instance the Asiatic Philosamia 
cynthia does. Whichever way this question is answered I am disposed 
to believe that its occurrence in North America originally will be found 
to be due to a comparatively recent importation.

Dear Sir :—After a knowledge of Mr. Grote’s criticisms of my lo- 
cation of my genus Cera/hosia, in Ento. Am., and afterwards in the Can, 
Ento., I sent a specimen of the species to Mr. H. B. Moeschler, the well- 
known European Lepidopterist, requesting him to give me, for publica- 
tion, his opinion of the family location of the genus. Mr. Moeschler 
writes me under date Sept. 28th,—‘‘To-day I received the parcel con- 
taining the two moths. I have examined them and, there is no doubt, 
you are right ; this species belongs to the Archide, as the costal nervule 
is not derived from the base of the hind wings, but from the discoidal 
cell; this characteristic separating the Arct#ide and Lithostide from the 
Nocturde, which have this nervule derived from the base of the wing, only 
a little connected with the fore edge of the cell. Ido not doubt this 
species is an Arcfid nearly allied to Devopera and Emydia.” 
Under date’ Sept. 30th, Mr. Moeschler again wrote me:—‘‘I re- 
ceived Enro. Americana, No. 6, to-day, and it was with great interest I 
read yours and Mr. Grote’s paper on Cerathosia tricolor, Sm. If Mr. Grote 
had looked into ‘Lederer’s Noctuinen Europa’s,’ he could read, page 2, 
‘sie (die Noc/uinen) unterscheiden sich von den Lithosiden (incl. Noda, 
Sarrothripa und Nycfeolz,) und Arciiden durch die bei diesen aus der 
Mitte oder */, des Vorderrandes der Mittelzelle entspringenden Rippe 8 
der Hinterfliigel.’ Mr. Grote would have spared much effort to prove 
something not existing, by reasons which are not of any vaiue, if he had- 
remembered the only important characteristic separating the Lithoside 
and Arciide from the Nocfuide. 1am much surprised that so distingu sh- 
ed a writer as Mr. Grote, could omit so important a characteristic, but— 
the systematic position of the genera of the so-called Zygenide in hs 
New Check List, is sufficient to prove, that Mr. Grote’s systematic views 
are sometimes more than singular !’’—Seeing the specimens of C. ¢ricolor, 
my first thought was, that it is a genus very closely allied to Devopeva 
( Utetheisa) and Lmydia, and | should have been much surprised if an 
exact examination had given another result.” 
So far as I am concerned, this closes the matter, except for the paper 
now in the hands of the printer, for the Proc. U. S. National Museum.
