290 THE ENTOMOLOGIST. 



Sequana, Curt. — Our series of this insect are generally much 

 mixed. Curtis copied his description from a manuscript of 

 Bentley, who wrote thus : " Similar to last [fulvovlttana, Steph.] 

 but smaller, and having no white in the superior wings, which 

 are purplish brown and variegated. An angulated brown space 

 at the base spotted with black, button large and ochreous 

 at the apex, with a short black streak beyond it, the semiloop on 

 the costa purplish grey, apex lead-coloured, inner margin 

 ochreous ; palpi, head, and centre of thorax pale ash colour." 



SuhfiLlvovittana, Clark. — Identical with fulvovlttana, Steph., 

 but the pale lunar crescent on the costa ends abruptly at the 

 central tuft, and is never continued upwards to join the costa 

 beyond it. 



[Cristalana, Don., and the same form with the addition of a 

 fulvous \iita,—falvovittana, Steph. — are both well known.] 



Procristalana, n. ab. — Like subfulvovittana, Clark, but without 

 vitta. Button light brown, changing to dirty white on its inner 

 side, where the white fascia from the costa blends into it. 



Chantana Group. 



Upper part of wing chestnut-brown. 



[Chantana, Bent. — Well-defined and equally well known.] 



In lots 318 and 319, at Clark's sale, were four specimens of a 

 modification of chantana with dark button. These were accepted 

 by Clark as albostriana, Haw., which we all know to be one of 

 the forms of Peronea hastiana. Having long had the same 

 insect in my cabinet, labelled postchantana, we may, I think, 

 call it by that name for want of a better. It differs from pro- 

 chantana by the large black tuft upon the primaries. 



Prochantana, Clark, which had been for many years in 

 cabinets mixed with chantana, is buttonless and easily dis- 

 tinguishable. 



Sabchantana, Clark. — May be compared with subvittana, 

 Steph., with pale ochreous button. It appears, however, very 

 distinct, and certainly belongs to this group. The fine ashj' line 

 along the fold from the basal blotch to the hind margin is not 

 shown in Clark's figure of this form. 



Vaughaniana, n. ab. — Light brown with a purplish gloss, the 

 upper part of the wing rufous, a dull red streak from the central 

 tuft to the costa before the apex. Button extremely small, 

 almost wanting, brown ; palpi, head, and thorax ash-coloured, 

 an ash-coloured line along the fold to the hind margin, generally 

 consolidated into an ashy grey patch at the extreme base of the 

 inner margin, similar to that of subchantana, but not so pale. I 

 dedicate this moth to the memory of my late friend, Howard J. 

 Wright Vaughan, who took a keen interest in the "buttons," 

 and was the first British entomologist to appreciate the im-
