116 ME. E. m'lACHLAI^ ON THE INSECTA COLLECTED 



silky pale smoky grey, rather darker at the apex, with the faintest 

 indicatioDs of a discal dot ; fringes pale silky grey. Underside uni- 

 formly very pale silky grey ; the anterior pair with the usual 

 spots and second line faintly indicated. 



Antennae black, rather silky. Palpi black, clothed with whitish 

 scales (excepting the terminal point). Body silky blackish; the 

 head and collar (especially beneath) clothed with whitish scales. 

 Abdomen with a large admixture of whitish scales ; anal tuft 

 greyish. Legs blackish, considerably clothed with whitish scales ; 

 posterior tibiae and tarsi almost entirely silky whitish. 



Expanse 21-23 millims. 



Three examples from lat, 82° SO' (Feilde?t), and two from the 

 * Discovery's ' winter quarters {Hart). 



Probably belonging to the group of S. sudetica. Remarkable 

 for its narrow and pointed anterior wings, dark colour, and the 

 very strongly curved second line ending in the inner margin con- 

 siderably within the level of the reniform spot. 



TOETEICID^. 



There are three individuals, belonging to distinct genera and 

 species ; only two are in tolerable condition, and I do not consider 

 it prudent to apply names to any of them. 



1. Fenthina^ sp., lat. 82° 30' (Feilden). A small species (ex- 

 panse 16 millims.), with nearly black anterior wings with a broad 

 darker central band. 



2. Mixodia ? sp. From the ' Discovery's ' winter quarters 

 {Sari). Having somewhat the aspect of M. Schulziana, but 

 smaller. In the British Museum are two individuals in wretched 

 condition from Arctic America, representing Betinia septentrio- 

 nana of Walker's Catalogue (pt. xxxviii. p. 373) ; but they do not 

 agree with the description of Orthotcenia septentrionana, Curtis, 

 Appendix, Eoss's Second Voyage, p. 77. 



3. . A large insect (expanse 26 millims.) from lat. 82° 30' 



{Feilden)^ utterly worn and unrecognizable. 



DIPTERA. 



The following is Baron von Osten-Sacken's report on this 

 Order : — 



TlPrLAEI^. 



Culex. — Erom Hayes Sound, Aug. 4th, 1875, apparently caught 

 by a spider, which is mounted on the same slide with it. This
