the hook quite at the tips, instead of having a regular curve 
and a gradual taper throughout. The cornuti are five or 
six in number, not very unlike those of dwhitalis but 
larger and stronger. The resemblance to duditalis is 
considerable, but the size is to that of dubitalis as 4 to 3, 
and the general appearance and texture is of at least 
corresponding density and robustness. 
Phaeoleuca (figs. 28-30) much resembles ingratella (figs. 
7 and 40) in having the cornuti very long, straight 
and slender, two long ones and one or two shorter often 
apparently only two, but the shorter are so closely ad- 
pressed to the longer that one suspects their existence 
as they cannot easily be made out. In ingratella these 
cornuti are much shorter and less robust than in phaeoleuca, 
being about 0°55 mm. long, whilst in phaeolewca they are 
about 0°8 mm. and much denser and stronger. 
Some specimens from Staudinger, sent as ambigualis, 
var. syriaca, are indistinguishable from phaeoleuca (assum- 
ing that I have the latter species correctly named)—at first 
I took them for ingratella. In any case they are certainly 
not ambigualis in any form. 
In perplexella (figs. 31-32, 69,71) the appendages are very 
large, equal in size to those of centwriella. The species is 
itself a large one. Unlike centwriella it isa typical Scoparia, 
nearer, perhaps, to dubitalis than to any of the others. 
Pyrenaealis (figs. 33-85) (with crataegella, though quite 
differently) has some characters making it intermediate 
between the root- and moss-feeders. It belongs rather to 
the root-feeders as having well-developed cornuti. These 
are long and slender, like those of phacoleuca or manifestella, 
but differ in being not straight but curved. The clasps, 
however, are those of the moss-feeder group in having no 
side spine or corresponding thickened basal portion. 
The specimen of incertalis I have is pyrenaealis, 
Crataegella (figs. 41-43) is a moss-feeder in fact, and as 
regards the appendages also, in possessing no cornuti. 
The aedoeagus is rather curved, and less slender than in 
most moss-feeders. It has a root-feeder character in a 
modified form, viz. the clasps have the _basi-ventral 
thickening, but this is narrower than in the connected 
species, and stretching further along the margin of the 
clasp, ends, not in a spine, but in a rounded thickening that 
is only just free at its end from the body of the clasp. 
In mounting this clasp it was found to differ from both
