THE GENERA OF BRITISH MOTHS. i 155 
The other species of this genus is C. semplana, one of the least of the group popularly defined as the T’s. 
The genus Chrosis. The general characters of this genus may be said to be as follows :—the palpi slender 
and longer than the head, the fore-wings rather more than twice as long as wide, and rather obtuse at the apex. 
The two British species, however, which belong to it vary materially. 
Chrosis tesserana (the Tessellated T, No. 10). The Caterpillar of this gaily-marked insect is unknown. 
The Moth appears both in June and August, and is very variable in colour. It is found most plentifully in 
chalky districts, the chalk downs of Brighton, Dover, &c., being recorded as places where it has been recently 
taken. There is a variety described by Stephens under the title Argyrolepia decimana. 
The other species is C. Auwdoutnana ; it has the fore-wings brownish-black, with an obscurely defined patch 
of orange at the tips. It is found where oaks abound in June and July. 
The genus Dapsilia. The insects assigned to this genus have the palpi longer than the head, and the 
anterior wings twice as long as broad, and rather blunt at the tip. There is only one British species. 
Dapsilia rutilana (the Scarlet-barred Gold T, No. 11). The Caterpillar of this pretty, and brightly- 
coloured species is yellowish-green, with the head bright orange. It feeds on the Juniper, in the foliage of which 
it surrounds itself by a thickly-spun web. It is full fed in June. The Moth appears in July and August. It 
is not scarce in chalky districts, especially in the chalky downs of Surrey. ; 
The genus Argyrolepia. The general characteristics of this genus may be said to be, long and slender 
palpi, the fore-wings narrow and elongate in general form, the front slightly arched, and the apex obtuse. But 
the species, though only seven in number, vary so considerably that they are divided into three sections, under 
separate distinctive titles, to denote their respective affinities with other genera. These three divisions are 
arranged in the following order :—Division A., Commophila ; B., Chlidonia ; C., Lozopera. 
Argyrolepia badiana (the Burdock T, No. 12). The Caterpillar of this species feeds within the stems and 
roots of Burdock. The Moth appears in July. It is widely distributed and plentiful wherever the Burdock is 
found in abundance. 
The other species, in this, the last division (Logopera), are, A. Baumanniana, A. Cnicana, and A. Dubrisana, 
of which last there are several varieties, formerly named as distinct species. In the first division ( Commophila) 
the species are A. neana, and A. Schrebersiana. In the second division (Chlidonia) there is only one species, 
A. Mussehliana ; of these A. Bawmannia is one of the handsomest. : 
The genus Lupecilia. The insects in this genus have the palpi scarcely projecting beyond the head ; the 
fore-wings are long and rather narrow, the front edge being nearly straight. There are seventeen species which 
differ considerably in their characters, and which are therefore arranged in four divisions, ‘‘ Notocella,” 
“ Asthenia,” ‘* Eupecilia,” and ‘* Cochylis,” in allusion to the genera to which these divisions bear respectively 
more or less affinity. 
Eupecilia dubitana (the Doubtful T, No. 13). This pretty Moth is on the wing in July and August, and 
has been recently taken at Bristol, Farnham, and one or two other places. It belongs to the first division of the 
genus. 
The other species are as follows :—In the first division (Notocella), EB. atricapitana. In the second division 
(Asthenia), EF. nana. In the third division (Bupeecilia), EF. maculosana, E. sodaliana, EB. Carduana, EB. 
ambiguella, EB. angustana, E. afinitona, B. Griseana, and £. notulana. In the fourth and last division (Cochylis), 
there are Z£. rupicola, EB. flaviciliana, E. roseana, E. subroseana, and £. ruficiliana. Many of these, from their 
bright yellow or rosy colours, are very attractive little insects. 
The genus Argyridia. The insects assigned to this genus have the palpi longer than the head, the fore- 
wings extremely long and narrow, being in length more than three times their breadth. The front of the 
anterior wings is nearly straight, and the apex acute. There is but one British species. 
Argyridia dipoltella (The Orange-barred Pearl T, No. 14). The Caterpillar of this delicately marked 
insect is unknown. It appears in the perfect form in July and August, but is very scarce. Several places in 
Surrey have, however, yielded recent specimens. 
The genus Lozopera. The insects assigned to this genus have the palpi rather slender, and projecting
