56 BRITISH MOTHS 
SPECIES 1—TRICHIURA CRATAGI. Puaret X., Fic. 13, 14. 
Synonymes.—Phalena (Bo.) Crategi, Linneus ; Donovan, vol. Diaphone Crategi, Hiibner, Verz. bek. Schm. 
4, pl. 117; Albin, pl. 24, fig. 54, a—d, and 88, fig. i. Bombyx Mali, Fabricius (B. Avellane, Fabr. Oliv.) Variety. 
Trichiura Crategi, Stephens ; Wood, Ind. Ent., pl. 6, fig. 45, 45. Bombyx pallidus, Haworth. Variety. 
The fore wings when expanded vary from 1] to nearly 13 inch, and in the males are of a pale ashy colour, 
with a brown fascia before the middle of the wing curved inwards, a second beyond the middle, dentate and 
black, the space between these fasciz being generally darker, with a black spot; there is also an indistinct . 
dentate streak running near the margin, and a marginal row of black dots; the hind wings are mouse-coloured 
or brownish. The female has the wings brown, with two or sometimes three nearly obsolete waved whitish 
streaks beyond the middle. Pale varieties of the female occur with the markings nearly as in the male, which 
Mr. Haworth regarded as distinct under the name of B, pallidus. The larva is black, with yellow hairs, pale 
fascize, and an interrupted lateral row of white spots; each segment is also marked with several red tubercles. 
It feeds on the whitethorn in May, and the moth appears in September. It is a comparatively uncommon 
species, but occurs in the woods near London, Epping, Bedford, and elsewhere. 

ODONESTIS, Germar. (COSMOTRICHE, Hisner.) 


This genus is at once distinguished from the preceding groups of this section of the family by the large size 
of the typical and only species, as well as by the elongated beak-like palpi, the slightly waved outer margin to 
all the short broad wings, the fore ones being acute at the tips, and the very strongly bipectinated antenna in the 
males ; the abdomen long and tufted at the tip in the males, but thick and conical in the females. The larva 
has the back furnished on each side with a tuft of short hairs; the sides of the body are thickly clothed with 
decumbent hairs, and a larger one on the back of the second segment behind the head as well as on the penul- 
timate segment. The cocoon is spindle-shaped and compact. 

SPECIES 1.—ODONESTIS POTATORIA. Puare X., Fie. 15, 16, 17. 
Synonymes.—Phal. (Bomb.) potatoria, Linneus; Albin, plate Odonestis potatoria, Germar ; Stephens; Wood, Ind. Ent., t. 6, 
17; Wilkes, plate 58; Harris, Aurelian, plate 42 ; Donovan, vol. 5, | f. 52, 52; Duncan, Brit. Moths, pl. 18, fig. 1, 2. 
pl. 148. Cosmotriche potatoria, Hiibner, Verz. bek. Schm. 
This fine, although common insect, varies from 2} to 3 inches in the expansion of the fore wings, which in 
the male are of a rich reddish buff clouded with fulvous, with two white dots placed one above the other, the 
upper one being the smaller, in the middle of the wing towards the costa; beyond which runs a straight dark 
line from the middle of the hind margin to the tip of the wing, and is succeeded by a more indistinct dentate 
line ; the hind wings and body are of the ground-colour of the fore wings. The female is altogether paler, being 
of a delicate fawn colour, but with similar markings to the male. The colours vary occasionally; being either 
lighter or darker in both sexes. ; 
The caterpillar is dark brown, very much freckled with pale dots, a yellowish line on each side, with white 
tufts of hair along the sides above the feet. It is very abundant in June, feeding on grasses, the moth appearing 
in the following month. It is very abundant throughout the country.
