THE CANADIAN ENTOMOLOGIST. 14'

fuscous or smoky. The size is larger. Lubens is also altogether a com- 

 paratively gaily coloured Noctuid, with violet and purple-brown shadings. 

 It recalls somewhat Copifnamestra brassicce, but not in any way does it 

 resemble a dead stone gray species, unicolorous in appearance. The 

 lines are partly yellow ; they cannot be described as " black, undulating 

 and denticulated." The type I saw allowed the fine lines, single, if I 

 remember rightly, to contrast and appear as if cut in the wing against the 

 even paler ground colour. The reniform was wide, kidney-shaped, 

 excavated outwardly. But let Mr. Walker speak for himself. That he 

 described Mamestra adjunct a and Xylomiges crucialis as Acronyctas is 

 true, but these have at least something of the Acronyda livery and 

 colours. Lubens has nothing of this, and is well described by Smith in 

 the Revision, p. 233, under cristifera. To this I can refer the reader. 

 Here is Walker's description from the British Museum Lists, XV., p. 1654, 

 1858. The Latin diagnosis I can omit, since it merely translates the 

 English text : 



" Male. — Dark cinereous, brownish beneath. Thorax with black 

 bands. Abdomen brownish-cinereous, with high black dorsal crests, 

 tufted along each side, and with a large apical tuft. Forewings with 

 some whitish hairs here and there, with black undulating and denticulated 

 lines ; orbicular and reniform spots and a third hindward spot mostly 

 whitish; orbicular large, nearly round; reniform slightly excavated on 

 the outer side. Hind wings brownish-cinereous, with whitish ciliae. 

 Length of the body 7 lines ; of the wings 16 lines. This species much 

 resembles A. hufnamelis, but is sufficiently distinct, a. St. Martin's Falls, 

 Albany River, Hudson's Bay. Preseted by Dr. Barnston." 



Walker's comparison with Acronyda hamamelis, though wide of the 

 mark, is only justified by the Acrotiycta-Wkt gray of his "type," which 

 wanted all warm Afamestra-\\ke reddish-brown tints. He calls a dark or 

 dusty fuscous-gray, a sordid stone-gray, " brownish-gray." There is not 

 the faintest resemblance to lubens in his description, in which species the 

 orbicular is dark centred, and in which character Walker's "type" agreed 

 with his description in being without dark centre merely somewhat paler, 

 more "whitish" than the wing. The type oi cristifera was not rough and 

 powdery like lubens, but nearly smooth. Could any sane entomologist 

 compare hibens with hatnamelis ? I think not. There was no trace of 

 purple, yellow, bluish-gray, violet, carmine or reddish-brown in Walker's
