162 THE GENERA OF BRITISH MOTHS. 
many variations to this rule, and indeed there are so many other slightly aberrant characteristics in the species 
assigned to this extensive genus, that it is divided into eleven sections named in accordance with the features 
of the species assigned to the respective sections. The Caterpillars are but little known, but it is ascertained that 
they feed generally in moss, constructing silky galleries which help to conceal their progress. 
Crambus Hamellus (the Pearl-streak Veneer, No. 3). This species, belonging to the section Argyrotecna, 
appears in July. The Caterpillar is unknown. The perfect insect frequents woods and forests in July and has 
been recently taken near Manchester, Weybridge, &c. 
The other species are arranged as follow :—Section 1, Thisanotia, containing two species, C. chirysonu- 
chellus and C. vorellus. The second section, Argyroteuchia, containing but a single British species, C. falsellus. 
The third section, Ancylolomia has likewise only one British species assigned to it, C. tentaculella. The fourth 
section Argyrotecna, contains seven species, C. pratellus, C. Dumetellus, C. Ericellus, C. Sylvellus, C. Hamellus, 
(the one figured), C. pascwellus and C. Uliginosellus. The fifth section, Chrysoteuchia, contains but a single species, 
OC. Hortuellus, (the Garden Veneer). The sixth section, Zzoria, contains two species, C. Culmellus, C. Pedriolellus, 
The seventh section, Pediasia, contains three species, C. inquinatellus, C. geniculeus and C. aridellus. The eighth 
section, Argriphila, contains two species, C. selasellus and C. tristellus (the Common Veneer). The ninth section, 
Eucarphia, contains a single species, C. furcatellus. The tenth section, Catoptria, contains three species, C. mar= 
garitellus, C. Pinetellus, and C. latistrius. The eleventh section, Selagia, contains three species, C. perlellus, 
C. Warringtoncllus, and C. lithargyrellus. Many of these species are subject to great variations of size and colour, 
and the most striking varieties of several of them were formerly considered distinct species and named as such. 
The sub-family Chilidi contains two genera, Schenobius, and Chilo, both of which have the general cha- 
racter of Crambus, except that the wings are generally larger and narrower, and more hooked at tip, from which 
they are popularly distinguished as the Hook-tip Veneers. 
The genus Schenobius. In this genus the antenne of the males are slightly ciliated, the anterior wings 
are very elongate, and extending to a long point at the apex, which is more or less hooked. There are three 
British species. 
Scheenobius gigantellus (the Gigantic Veneer, No. 4). This elegant and slenderly formed species, is found 
in marshy places in June and July, the female differs from the male in having the fore-wings unspotted, and the 
hind-wings entirely white. The Caterpillar is described by Treitschke as of a pale-yellow colour tinged with 
grayish, the head and second segment being of a bright orange-brown. It feeds in the stems of the reed 
Arundo Phragmites; this insect is very rare, it has been taken most frequently in the marshes about 
Whittlesea-mere. 
The other species are S, mucronellus (the Dark Hook-tip Veneer), and S. forficellus (the Pale Hook-tip 
Veneer), which last is subject to great variation in the markings of the fore-wings, and the most striking of the 
varieties have been considered distinct species hy Haworth, under the names of Palparia, hirta, P. fumea, P. 
caudex, &e. 
The genus Chilo is distinguished from Schwnobius principally by the larger size, and still more slender 
wings. The males have the antenne slightly hairy, the females simple. There are two British species, 
C, Phraginitellus and C, cicatricellus. 
Chilo Phragmitellus (the Wainscot Veneer, No. 4). This insect is the largest of all the Crambide. The 
wings of the female are less long and acuminated than those of the male. The Caterpillar is described by 
Treitschke, as being of a pale bone-colour with five brown stripes, the head and second segment being of a bright 
orange-brown. It feeds on reeds, especially the Arundo Phragmites, and is found both in October and March, 
The perfect Moth appears in June and July, and is found in the neighbourhood of Whittlesea-mere and other 
marshy districts. 
The reputed British species of Crambide are the following :—Nephopleryx Rhenella, Eurhodope argy- 
vella, Pempella stigmatella, <Acrobasis cristella, Myclois legatclia, Homeosoma binevella, Ephestia Ficella ; 
Hypochalcea lignetla, Melissoblaptes ancllus ; Prionapleryx nebulifera, Crambus intervibrellus, Cambrus luteellus, 
Crambus combinellus, Crambus deliellus, and Crambus radiellus.
