NOCTUID.E. MAMESTRA. 195

Tlie size and form of the last : the anterior wings with the ordinary stigmata, 

 and a strongly bidentate striga towards the hinder margin whitish. 



I do not believe that this insect is truly distinct from Ma. Bras- 

 sicse ; but rather suspect that it will prove to be merely a suffused 

 variety of that species, having some of the characters, as usual in 

 such cases, apparently more distinct. The original specimen is in 

 Mr. Hatchett's collection, but I believe a second has been found. 



Sp. 9. albicolon. Plate 24. f. 3. Aiis anticis fusco-grise is, macula reniformd 

 punctis duobus albis strigdque externa Jlavescente punctata. (Exp. alar. 1 unc. 

 8—9 hn.) 



No. albicolon. Hllbner. — Ma. albicolon. Steph. Catal. pt. ii. p. 83. No. 6222. 



Rather larger than Ma. Brassicse : head and thorax deep cinereous, mixed with 

 paler and darker shades, with an obscure transverse anterior line : anterior 

 wings of similar hue, a little clouded with fuscous, with several rather obscure 

 darker strigse, and an interrupted, scarcely undulated, series of distinct yel- 

 lowish spots in place of the posterior striga : stigmata pale cinereous, the pos- 

 terior slightly clouded, with two distinct white spots adjoining the posterior 

 angle : the third stigma wanting : posterior wings ochraceous-ash, with the 

 border fuscous : cilia pale. 



The total absence of the third stigma on the anterior wings, with the row of 

 flavescent spots near their posterior margin, and the pale ochraceous-ash pos- 

 terior wings, exclusively of its size and dissimilar colour, sufficiently distinguish 

 this insect from Ma. Brassicae, with which it appears to have been confounded. 



Of this plain, but remarkably distinct, insect I have seen six 

 specimens only, which were captured in August, 1827, by Mr. 

 Weaver, in Cumberland. 



Sp. 10. Chenopodii. Alis anticis fusco-cinereis nigro maculatis, stigmatibus 

 tribus, stigmate reniformi nigricante, strigd posticd hidentatd alba. (Exp. 

 alar. 1 unc. 4 — 6 lin.) 



No. Chenopodii. Wien. Verz. — Ma. Chenopodii. Steph. Catal. part ii. p. 84. 

 No. 6224. Albin. pi. xxix. / 44. e—d. 



Head and thorax cinereous immaculate ; antenna; fuscous : anterior wings cine- 

 reous, with irregular black and pale strigse and fuscous clouds, with a 

 slender bidentate white striga near the posterior margin, which has a row of 

 minute black spots ; the costa is also spotted with dusky-black, with three 

 distinct minute white dots near the apex : the anterior stigma is pale with a 

 dark border, the posterior dusky margined with cinereous and black ; there 

 is also a third stigma, as in Ma. Brassicje, dusky with a black margin, but ex- 

 tremely variable in size : posterior wings cinereous, with the nervures, central 

 spot and margin fuscous.
