and added three species as new — hilarella^ scabeUa^ and nehalosa. Of 
these hilarella is clearl}^ the same as Packard's rohiniella^ not known 
to Zeller. 
V. T. Chambers described a number of species under the name 
Depressaria which did not belong there. Several of these he himself 
removed, and in his Index he only retained the foregoing of other 
authors and live of his own species, namely, eajxitorlella, fernaldella., 
pallldochrella,, rileyella^ and versicolor ella^ the last three with a query 
and the note: "Probably to be referred to Gelechla.'''' Of these onl}'^ 
the first, eupatoriella^ belongs to the genus, and this is now found to 
be the same species which Clemens described as pidvij^entiella; fer- 
naldella is evidently Machiinia tentoriferella Clemens, as determined 
by Professor Fernald and Lord Walsingham; ixiUidochrella belongs 
to the gelechiid genus Gnorimoschema^ as Chambers's type in Cam- 
bridge proves; rileyella is found by the type in the U. S. National 
Museum to be a Gelechia^ and verslcoloTeUa^ while not at present recog- 
nized with certainty, is evidently a gelechiid from Chambers's note on 
that species and palUdochrella: "Posterior wings deeply emarginate 
beneath the apex." 
Two other species of Chambers's, however, described under Gelechla^ 
namely, tlioracenigraeella and thoracefasciella, are found on examina- 
tion of the authentic types in the Cambridge Museum to belong to 
Depressaria^ and one other species, placed by Chambers under Gele- 
chia, namely, clemenseUa^ has been identified by Lord Walsingham as 
Depressaria applana Fabricius, of Europe. 
In 1881 Lord Walsingham ^ reviewed the genus and included the 
species in Chambers's Index, besides describmg and figuring eight new 
sj)ecies, namely, sabulella^ argillacea^ arnicella^ Marnatldana^ jnisti- 
cella^ nuhiferella^ jpsoralieUa^ and umhraticostella. He also recognized 
from this countrj^ five European species, namely, c'lliella Stainton, 
yeatiana Fabricius, nervosa Ha worth, emerUella Stainton, Q.nd jxirUeUa 
Treitscke, the latter with some hesitation, and providing the name 
novi-nnmdi for his specimens if it should prove a distinct species. 
Of these the supposed yeatiana Fabricius was afterwards^ redeter- 
mined by Walsingham as the European arenella Schiffermiller, and 
the nom-m.midi it will be safer to regard as a distinct species at pres- 
ent, though Lord Walsingham seems to think ^ that it ma}' be one of 
the many varieties oi parileUa. 
In 1882 Lord Walsingham* further added the new species ^/^//wir. 
In 1883 D. W. Coquillett'' added a valuable contribution to our 
knowledge of the genus by publishing the life histories and food 
plants of four species, namely, pulvipennella, atrodorsella^ grotella^ 
and what was supposed to be hilarella.
