our G. Populella^ but tlie anterior wings are broader and blunter, and 
the anterior segments of the body are not pale. 
Gelecliia? ruhidella; a true Gelechia^ somewhat allied to G.erici- 
but smaller and the anterior wings narrower. 
Gelecliia detersella. I am uncertain about this; it is perhaps allied 
to our moss-feeding G. The name detersella must be altered, 
that name having been used by Zeller for a Sicilian species of the 
genus. (Isis 1847.) 
The genus Gelecliia as at present constituted, is very elastic and in¬ 
cludes a variety of slightly different forms. Gelecliia subocellea is 
our most discordant species. 
Strohisia iridipenneUa and Strohisia Emhlemella. These are very 
different from any thing in Europe, and the form of wing in Iridi- 
pennella is so peculiar that you are clearly justified in forming a new 
genus; it is not improbably a connecting link between Gelecliia and 
Glypliipteryx. 
ButaMs jiavifran fella and Butalis matutella. Zeller has described 
in the Linnma Entomologica, Yol. X, several North American species 
of Butalis. His Basilaris, p. 230, is perhaps identical with your 
Flavifrontella, and his Impositella, p. 241, may have been described 
from a worn specimen of your llatutella. 
Stilbosis tesquella. This is a very curious insect resembling in form 
of wing Asychina seratella; the ornamentation is more like some of the 
Lavernse. 
Clirysocorys Erytliriella. This is a true Clirysocorys. 
Brentliia Pavcmacella. I am disposed to consider this not a Tineina, 
but rather one of the Pyralidina allied to Simeetliis., but I have never 
observed the strutting habit in any of our species. 
Pigritia laticapitella. This is an obscure looking insect of doubtful 
location, reminding me most strongly of some of our aberrant BnUdidse.
