40 THE GENERA OF BRITISH MOTHS. 
Dart) ; A. Aquilina (the Streaked Dart) ; A. Tritici (the White-line Dart) 5; A. Ripe (the Sand Dart); A. Nig: icans 
(the Garden Dart) ; A. Puta (the Shuttle-shaped Dart); A. Cineria (the Light Feathered Rustic). The popular 
names of two of the above, the Dark Sword Grass and the Light Feathered Rustic, show that they were originally 
placed by popular collectors in different groups, and not reckoned among the true “ Darts ;” while species of two 
genera about to be described, Oppigena and Spealotis, have been placed by recent classifiers in the genus Agrotis. 
The genus Cenophila contains only one British species, formerly a Graphiphora, which has been separated 
from that genus, as well as from Agrotis, on account of its strongly pectinated antenne and the greater breadth 
of its hind wings. Canophila Rosca (No. 6) is a very handsome insect, the anterior wings having, in very perfect 
specimens, a fine rosy flush. It is rare, but is found at Whittleseamere, and no doubt in other similar localities. 
Spelotis* is another genus recently formed by Dr. Boisduval, to include certain insects formerly classed with 
the Graphiphora, but which have been found to exhibit sufficient distinctive characters to warrant their separation. 
Spelotis Ashworthii (the Welsh Rustic, No. 7), though still classed by some as an Agrotis, forms a good 
illustration of the general character of the new genus. The Caterpillar is green, with a paler dorsal line, and has a 
lateral whitish streak. It has been found in the neighbourhood of Llangollen, whence the popular name, the Welsh 
Rustic. 
Spelotis Pyrophila (the Dotted Rustic) is exceedingly distinct in its colour and markings from the preceding 
species, as shown at No. 8. It is rare, but very widely dispersed, having been found in the north of Scotland. 
The genus Oppigena was established by Dr. Boisduval in 1840, for certain species differing in some respects 
from Agrotis, Spelotis, or Graphiphora. A solitary British species has been assigned to it—O. Fennica—of which only 
one specimen has been taken in Derbyshire, and popularly named the Beautiful Dart. It is by some authors classed 
with Agrotis. The fore wings are of a deep violet grey, approaching black, the inner margin ochreous. The stigma 
marked with a very distinct light cream-coloured outline ; the hind wings are pale brown. 
The genus Graphiphora is principally distinguished from Agrotis by having the antenne simple in both 
sexes, or only very slightly pectinated in the males. The fore wings are broad, and obtuse, and generally glossy. 
The markings, though similar to those in Agrotis, differ in having the two ordinary-shaped stigmata even more 
clearly developed than in Ayrotis, while the dart-shaped one, so remarkable in that genus, is generally obsolete or 
nearly so in Graphiphora. 
Graphiphora Brunnea (the Purple Clay, No. 9) is one of the best defined species, exhibiting all the character- 
istics of atrue Graphiphora. The Caterpillar is brown, with yellowish markings along the back, and some conspicuous 
yellow spots and oblique streaks along the sub-dorsal line ; the line above the legs is greyish buff. It is found on 
various low plants in spring, and is not very rare. 
Graphiphora Festiva (the Ingrailed Clay, No. 10) forms a contrast to Brunnea in the paler, but yet distinct, 
markings of the fore wings, while the hind wings are more varied in tone by two deep borderings, very distinct in 
fine specimens. The Caterpillar (No 11) feeds on primrose in June, the Moth appearing in July and August. It 
is not rare, though somewhat local. 
Graphiphora Triangulum (the Double-square Spot, No. 12) is another very distinct and well-marked species. 
The Caterpillar is reddish-brown, with paler stripes ; it feeds on the deadly nightshade and other plants in April, 
and the Motlf appears in July. It is not a rare species. 
There are nine other species, among which the most remarkable are G. Plecta (the Flame Shoulder), with 
a broad stripe of pale yellow along the front of the wing ; the rare G. Depuncta, with its-fine brown markings on 
an ochreous ground; and G. C.-Nigrum (the Setaceus Hebrew Character), with its conspicuous ochreous patches in 
front of the stigmata, between which is the dark marking in the form of a Hebrew letter. The remaining species 
are G. Baja, G# Dahlii, G. Rubi, G. Rhomboidea, G. Ditrapezium, and G. Glareosa. 
* Spalotis Ashworthii and Oppigena Fennica are, in Mr, Stainton’s Manual, placed in the the genus Agrotis.
