C. Fluctuosa, C. Duplaris, and C. Ridens, are from the cabinet of Mr. Marshall ; C. Octogesima from the cabinet of Mr. Bentley ; and the 
others are from specimens furnished me by Mr. H. Doubleday. The caterpillars are from Hiibner. H.N.H. 
CERATOPACHA, (CEROPACHA, Srepuens, TETHEA ». Curtis.) 
The genus Tethea of Ochsenheimer, or Cymatophora of Treitschke, having been found to require subdivision, 
it is unfortunate that modern Lepidopterists have not adopted some regular plan in respect to the nomenclature 
of its subdivisions : as it is, each has adopted a different mode of dealing with the old synonymous names, and 
consequently, each has a different series of names for the groups in question. As the insects composing the 
present group are not the types either of Ochsenheimer or Treitschke’s generic names, I have followed Mr. Stephens 
in preference to Boisduval. In this group, the fore wings are either obtuse or angulated, with several waved 
transverse lines; the antenne simple in both sexes, stout, short, and rather depressed in the middle, very 
pubescent beneath; the palpi horizontally porrected, with the terminal joint rather long and slender; the 
abdqmen variable in thickness ; the thorax rather broad, with the tippets elevated so as to appear bifid. The 
caterpillars are pale-coloured, punctured and depressed, the head broad, cordate, and variously coloured. 
SPECIES 1.—CERATOPACHA FLUCTUOSA. Puate XLIII., Fie. 1. 
Synonyme.—Woctua fluctuosa, Hiibner ; Haworth; Treitschke; Curtis; Stephens; Wood, Ind. Ent. pl. 14, fig. 328. 
This species varies from 11 to 12% inch in the expanse of the fore wings, which are of an ashy-white 
colour; the base pale with a brown striga and spots, beyond which is a broad brown straight bar, extending 
beyond the middle of the wing, in which are two flexuous black strigw@, and a black lunule, externally white, 
occupying the place of the outer stigma ; beyond the fascia isa clear brownish striga finely denticulated, the apical 
margin dusky, in which is a pale denticulated striga ; the anterior stigma is obsolete; the hind wings are whitish, 
with a pale dusky fimbria ; the body is slender. 
The caterpillar is yellowish white, with a dark brown head ; it feeds on the birch. The perfect insect appears 
about the middle of June, frequenting the skirts of woods in the southern counties. 
SPECIES 2.—CERATOPACHA DUPLARIS. Puate XLIII., Fie. 2. 
Synonymes.— Tinea duplaris, Linneus ; Haworth (Noctzza d.) Noctua bipuncia, Borkhausen; Treitschke; Boisduval ; Guénée; 
Stephens ; Wood, Ind. Ent. pl. 14, fig. 329. Doubleday. 
Noctua bicolor, Esper. Nocta undosa, Hiibner. 
Noctua binotata, Fabricius. 
This species varies from 14 to 14 inch in the expanse of the fore wings, and is very closely allied to the 
preceding insect, but it is smaller and darker in the colour of the wings, and has two small black dots in 
the place of the outer stigma instead of the dusky Iunule; the apex of the fore wings is much more broadly 
saturated with dusky brown. The caterpillar is yellowish green, with a red line down the back, and reddish- 
brown head ; it feeds on the poplar. The moth appears at the same time and places as the preceding, but is 
much more common, Darenth, Ripley, Petworth, New Forest, Epping, &c.
