indeed an inspection of "Wood's figure 236, seems to prove. As, however, Boisduval keeps them distinct 

 (but placed next to each other, whilst Guencc removes Satura to his genus Aplecta), it will perhaps be 

 useful to o-ivc Mr. Stephens's description, which is as follows: — Hadena satura (Steph. 111. H. 2, p. 181.) 

 " The wino-s are deeply marked witli black, and a very conspicuous straight black liiieola unites the third and 

 fourth ordinary strio-aj on the anterior wings, at the base of which is a black streak, and a dusky one near the 

 base of the inner margin ; the stigmata are pale brownish-ash with slender black edges, the posterior one 

 somewhat tinted with yellow ; on the liinder margin of the wing is a pale striga composed of numerous acute 

 denticulations, of whicli two arc more conspicuous, and form the usual W mark of the group ; the cilia are 

 brownish, interrupted with pale cinereous, and preceded by a series of conical black spots ; posterior wings 

 dusky, with the margin, nervures, and a central lunule of a darker hue." Mr. Stephens is not aware of the 

 habitat of Marsham's two specimens, but thinks they were most probably taken near London, the insect having 

 moreover been t.aken, lie believes, at Coombe Wood. Jlr. II. Doubleday also informs us that Mr. Weaver has 

 this season (1842) taken a moth, in Scotland, which may be the true IT. satura. 



Note. — Hadena arnica, Stepliens, III. Haust. 2, pi. 23, fig. 2, (N. satura, Haworth, but not of Hiibner.) is omitted, on tlie authority of 

 Mr. H. Doubledav, who informs us *' that it is an American species, being very couimon in tlic United States, where his brother, Mr. Edward !>., 

 took it in abundance. It was, like many other American species, in Francillon's and other old cabinets." 



SPECIES 2.— HADENA REMISSA. Pl.^te XXXIII., Fio. 2.

Noctna gemina, Hiibner, fig. 482 ; Trcitschke. 



This species measures from I^ to I J inch in the expanse of the fore wings, which are of a pale brown, 

 clouded with darker shades, the cosfa being pale and marked with several small dark patches ; the four ordinary 

 striga; are present, the two basal ones considerably undulated, with two black patches towards the base of the 

 wing ; the stigmata are pale, with the centres more or less dusky, and partially edged with black ; a black stripe 

 also runs behind the stigmata (whicli are placed on a large brown patch) connecting the two middle striga?, 

 beyond which the veins are dotted with black aud white ; the outer striga is pale and less indented than in the 

 preceding species. The hind wings are pale brown, with margin darker. 



A rare species, although widely distributed. It has been found in the woods of Kent, Surrey, Essex, 

 Hertfordshire, York, Cambridgeshire, and Shropshire. 



Hadena oblonga of Ilaworth is, we believe, now considered to be but a variety of H. remissa ; but as some 

 doubt remains on the subject, we add a translation of Mr. Haworth's character. " Wings ashy, clouded ; the 

 costa, and an oblong patch, brown ; and a white very much undulating streak along the posterior edges of the 

 fore wings, which are semi-fuscous, the inner half of the wing being more ashy-coloured ; the costal spots, apex, 

 and ordinary stigmata are also asiiy-coloured ; and there is a large brown wedge-shaped spot on the hind part of 

 the wing, and another oblong one towards the inner edge ; the hind wings whitish, with the margin brown." In 

 other respects it agrees with the preceding. Found near Wisbeach, also at Coombe, Darenth, Epping, and in 

 Yorkshire.
