Noctua hospital is Grote. 
Of this species I knew only the female type from the Hill collection 
in 1890. Mr. Grote was inclined in 1886 to consider this a form of 
per con flu a, but as I pointed out, it is much nearer to the European 
brunnea. Two years ago Dr. Ottolengui took a perfect male at Man¬ 
chester, N. H., which he kindly gave me, and recently I saw a specimen 
in the Strecker collection, labelled simply “ N. Y.” 
The latter specimen was named brunnea and, compared with Euro¬ 
pean examples in the same collection, no superficial differences were ap¬ 
parent. In view of what has appeared in other instances notably that 
of baja— it would be unsafe to cite the two as identical; hence I present 
a picture of the male genitalia (Plate VII, fig. 9) for comparison with 
those of the European brunnea by any one with specimens of the latter 
at hand. 
Noctua rub if era Grt. 
There has been much confusion in collections between rubifera and 
perconflua , and even labels in Mr. Grote’s handwriting are not always 
correctly applied. When the western forms were added, leading to 
rosaria , the confusion became yet greater and there seemed to be almost 
no line of division. Esunalis Grote, described from Washington I re¬ 
ferred from a comparison of types in 1891 as a probable geographical, 
race of perconflua. 
Within the last five years I have received material in this group 
from all the Pacific Coast States, from Vancouver, from British Colum¬ 
bia, from Manitoba and from Calgary, and the result of a renewed 
study has been the conclusion that there are more species than has been 
realized, and that even in the East two species have been confused under 
the name rubifera. Fortunately Mr. Grote gives us a figure of his spe¬ 
cies (Can. Ent., VII, pi. I, f. 14), and of this type I have four examples 
from Orono, Me., Sharon Springs and the Adirondack Mountains, New 
York. 
The sexual characters of the two males agree, and are not those fig¬ 
ured by me on pi. IV, f. 37, Bull. 44 U. S. Nat. Museum. . They are 
represented on the accompanying Plate VII, fig. 2. I his species has the 
primaries rather narrow, especially in the male, the apex almost rect¬ 
angular, outer margin evenly curved and the inner margin nearly 
straight. None of the ornamentation is at all contrasting, yet in most 
specimens a diffuse darker median shade is traceable.
