THE CANADIAN ENTOMOLOGIST. iss: 
incline to think that the maturity of the imago at the time of its death 
has something to do with the color of the hind wings, specimens killed 
very soon after emergence having them more slaty or lead colored than 
older ones. |

In my former notice of this species I placed it, provisionally and with 
great doubt, in Stephens’ genus /Æeribeia. I find, however, that either 
fleribeia Stephens is very different from the Heribeia of more modern Eng- 
lish authors (which includes such small genera as Philocnistis, Lyonetia, &c.,) 
or I have mistaken the characters of Stephens’ genus from his brief 
diagnosis. I had supposed it (from the characters given by Stephens and 
its location among his genera) to be allied closely to Yfonomeuta. At any 
rate, as I cannot satisfactorily locate this species in any genus known to 
me, I think it best to erect a new one for it with the diagnosis given at 
Pp. 43— Vol. 4. 
It differs from YVfonomeuta in the colors and patterns of coloration ; 
in having the terminal joint of the labial palpi a little larger in proportion 
to the others ; in having the head entirely smooth ; in having the primaries 
a little falcate beneath the apex, though the neuration is not materially 
different ; in having the costal margin of the secondaries a little excised 
before the tip, which is pointed, and in having only a single branch (the 
-superior furcate one) given off from the discal vein (while Yponomeuta has 
an inferior simple branch also), and in having the median furcate from the 
end of the cell, whilst in Vponomeuta it is simple.

_ Although Dr. Clemens’ description is not strictly accurate, or rather, is 
not altogether intelligible, where applied to the insects now before me ; 
and I have not seen his specimens, yet notwithstanding the close resem- 
blance which sometimes exists between different species of this genus, I 
have very little doubt that my specimens belong to this species. Should 
it, however, prove otherwise, then I suggest for these specimens the name 
G. juglandivorella and annex the following description :
