114 ME. E. M'lACHLAK ON THE INSECTA COLLECTED 



pair rather broad, somewhat acuminate, curved very strongly- 

 upward, the lower edge strongly convex, the upper strongly con- 

 cave : penis slender, very strongly curved. 



Expanse 39 millims. 



Only one 2 from Dobbin Bay, 15th August, 1876 (Feilden). It 

 is in a fair condition, but has apparently been crushed in a book. 



I am unable to identify this with any described species from 

 Lapland or boreal America, and have therefore ventured to de- 

 scribe it as new, notwithstanding the great variability and uncer- 

 tainty in boreal Noctuae. The most conspicuous feature consists 

 of the pale posterior wings, with their very broad blackish border 

 and large black central spot. A systematic examination of the 

 anal appendages of the males of this group will certainly tend to 

 render the separation of species comparatively easy. 



I am not clear as to the true generic position. The hairy eyes 

 would place it in Mamestra as defined by Grrote (Bull. Bufi'alo 

 Society, ii. p. 3) ; but the spinous tibiae and tarsi are opposed to 

 this connexion, as also probably are the serrate antennae. Owing 

 to the manner in which the example has been crushed, the dorsal 

 crests are not definable. 



A Noctua-larva indicated as from Shift-rudder Bay, August 

 1876 {Feilden), and numerous others taken from the stomach of 

 a Tern (Discovery Bay, Hart), possibly belong to this species. 

 They are of the form usual in Mamestra. 



Pltjsia paeilis, Hubner. . 



One worn example from Hayes Sound, lat. 79° {Feilden). 



A rare insect, recorded from Lapland, Labrador, and Grreen- 

 land. A specimen from Fran Island, Arctic America (Voyage 

 of the ' Investigator ') is in the British Museum, and forms the 

 type of P. quadriplaga. Walker, Cat. Brit. Mus. Lepidopt. pt. xii. 

 p. 911. 



GrEOMETE^. 



PsTCHOPHOEA Sabini, Kirhy. 



Eight el^amples. Lat. 81° 52', 82° 27', and 82° 30' {Feilden), in 

 July and August, and from the ' Discovery's ' winter quarters 

 {Hart). Also two examples from Upernavik {Hart). An indi- 

 vidual was seen by Capt. Eeilden still further north, but not cap- 

 tured. 



A known Arctic species, recorded from most of the Polar expe- 

 ditions. Taken by Dr. Bessels at Polaris Bay, lat. 81° 38'.
