the sides as the true Depressarie, and the brush is as distinctly divided. 
Their small size, narrow fore wings, and deep emargination of the hind 
wings beneath the apex, suggest doubts as to the propriety of their loca- 
tion in Depressaria. 
I have described the neuration of these species as compared with 
Depressaria in a previous paper. 
In all of these species (except dwbitella ?) the wings in the living insect 
are carried almost horizontally, or but little deflexed, in repose. 
One colourational peculiarity is common to many of the species which 
I have placed in Depressaria and to many species of Gelechia ; that is, 
the costal pale streak at the beginning of the ciliæ, and the opposite 
dorsal one. Another peculiarity, though possessed by some Ge/echia, is 
more characteristic of Depressaria : that is, the small ochreous or brown 
spot or spots on the disc. Gelechia dubitella (Depressaria dubitella, ante), 
has the discal ochreous spot, but not the costal or dorsal streaks. WD. ? 
‘cercerisella has the costal and dorsal streaks and about four small ochreous 
spots on the disc. (By an oversight, I omitted to mention these in the 
description). In 2.? dimaculella, the costal and dorsal streaks are white, 
and there is a rather large white spot on the disc. In 2. Ri/eyella and ~ 
D. fuscoluteella, the costal and dorsal streaks are absent, and the discal 
spots are minute, indistinct, and dark brown. 2.7 pseudacaciella has the 
costal and dorsal streaks, but not the dots on the disc. So have D. 
bistrisella and D. bicostomaculella. In D. quercielia, D. pallidochrella, D. 
versicolorella, D. fusco-ochrella, and D. obscurusella, neither the marginal 
streaks nor discal spots are perceptible. ~ 
Though I think that hardly enough weight is given to the ‘‘ pattern of 
colouration,” as characteristic of genera, and even perhaps of higher 
groups, neverthless its value is subordinate to that of structure, and in the 
genus allied to Gelechta, one is soon at a loss as to what value really 
should be attached to it. As the genus Ge/ec/ia is at present constituted, 
I do not doubt that many, perhaps most entomologists, would place the 
majority of the above described species in that genus. But a genus which 
contains them, and such species as G. voseosuffusella (which Mr. Stainton 
says 1s a true Gelechia), to say nothing of such species as G. Æermonella, 
is certainly a hetorogeneous assemblage. Perhaps, however, that is not a 
very serious objection, for in my humble judgement no well defined and 
constant line exists between Defressaria (including in it Axaeretia and 
Orthotelia) Cryptolechia, Gelechia and other allied genera, and the more
