and a very conspicuous straight black lineola unites the third and 

 fourth ordinary strigse in the anterior wings" ('Tllus.,' ii., p. 181). 

 I should call the complete basal and elbowed lines the second and 

 third strigse. Of this variety Guenee writes: "Generally darker, 

 the upper part of the elbowed line more distant from the reniform 

 than in the type ; the nn-like mark which unites the two median 

 lines better marked ; the cuneiform marks on the subterminal more 

 pronounced. The inferior wings darker " (' Noctuelles,' vi., p. 85). 

 Humphrey and Westwood write : " Dark varieties of this species 

 (adusta) occur in many cabinets under the name of H. satura. Mr. 

 Stephens also considered it possible that his specimens described under 

 that name might be varieties of H. adusta, as indeed an inspection of 

 Wood's figure 236, seems to prove. As, however, Boisduval keeps 

 them distinct (but placed next to each other, whilst Guene'e removes 

 satura to his genus Aplecta), it will, perhaps, be useful to give Mr. 

 Stephens' description, which is as follows : 'Hadena satura (Steph.,* J1L, 

 Ha.,' 2, p. 181) The wings are deeply marked with black, and a very 

 conspicuous straight black lineola unites the third and fourth ordinary 

 strigse 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 some- 

 what tinted with yellow ; on the hinder margin of the wing is a pale 

 etriga composed of numerous acute denticulations, of which two are 

 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 taken, he believes, at Coombe Wood. Mr. H. Doubleday also 

 informs us that Mr. Weaver has this season (1842) taken a moth in 

 Scotland, which may be the true H. satura " (* British Moths,' 

 pp. 161-162). I believe this latter specimen did, in fact, turn out a 

 genuine example of satura, but there is no doubt that Stephens' 

 satura is nothing but adusta.

I quite agree with Guenee when he remarks : " Although this 

 species often varies in the shade of its green colour, and in the greater 

 or less distinctness of its markings, it does not merit the name which 

 has been given to it. I am not able to classify the varieties into dis- 

 tinct races " (' Noctuelles,' vol. vi., p. 89). Borkhausen's description 

 of the type is : " The ground colour of the fore wings is a mixture of 

 whitish-grey, brown and green, which is intermingled in mottled 

 shadings ; the markings are difficult to distinguish, yet, on closer in- 

 spection, one perceives four dark stripes, of which the first, near the 

 base, ends in the middle of the wing in a small streak starting from 

 the base. The second, in an undulating manner, turns its course in a 

 slanting way towards the inner margin. The third, with a strong 

 angle turns towards the outer margin and approaches closely the second 

 near the inner margin. Lastly, the fourth is strongly dentate close to 

 the hind margin. Between the two middle ones is seen a mark which
