Nymphalid^. 



1. Argynnis cytheris, Drury. 



Two pairs taken in Elizabeth Island in January 1879. The males 

 agree well with Drury's figure and with Reed's figure of A. anna 

 (Blanchard) ; one of the females also agrees very fairly with 

 Blanciiard's figure of A. lathonioides. The allied form, regarded by 

 Reed as the A. cytheris of Drury, seems quite distinct, and must re- 

 tain the name of A. montana given to it by Reed upon his plate. 



PaPILIONIDjE. 



2. Tatochila demodice, Blanchard, 



One female captured on the 6th of January in Elizabeth Island. 



Lasiocampidjs. 



3. Phricodia humeralis, var., Walker. 



A male caught on board in the Straits of Magellan, and two females 

 in Elizabeth Island on the 6th of January. These specimens are 

 altogether redder and darker than the typical form. 



Episemid^. 



4. Heliophobus?, sp. 



Puerto Bueno, Straits of Magellan, 20th of January, 1879. The 

 two examples of this species are so much rubbed that, although the 

 Moth appears to agree in structure with Heliophobus, it is quite im- 

 possible to decide whether or not it is referable to any known species. 



Apamiid^. 



5. Mamestra?, sp. 



The single example obtained, although evidently referable to a 

 well-marked species, is unfortunately too much worn for recognition ; 

 the antennae are wanting. 



Straits of Magellan, exact locality not noted. 



It is not impossible that this may prove to be an Affrotis when we 

 see a perfect specimen. 



NoCTUID^. 



6. OCHROPLEURA MAGELLANICA, Sp. n. 



Primaries chocolate-brown, with very slight purplish reflections, 

 the basal two thirds of costal border broadly pale sandy brown ; the 

 orbicular and reniform spots of the same colour, with slightly darker 

 centres, the orbicular with oblique outer margin and confluent with 

 the costal border along its anterior margin : secondaries pale sericeous 

 greyish brown, with slightly darker diffused outer border and pale 

 sandy-yellow fringe : thorax chocolate-brown ; head, antennae, and 

 shoulders ochraceous ; abdomen fuliginous brown, whitish at the 

 base, and with ochraceous lateral fringes and anal tuft. Primaries 

 below pale fuliginous brown ; secondaries whitish, with pale fuliginous
