collection are noticed by name only, viz. A. glacialis, Hag., from 

 North America, and A. islandica, Hag., from Iceland. 



Phbtganea, Linne. 

 Phryganea sordida, nov. sp. P. varies affinis, sed alis anticis 



latioribus, fusco-griseis fusco plus nebulosis ; alae posticae ad apicem 



anguste fusco -limbatae ( $ ). 

 Long. corp. 7h hn- (=15 mill.); exp. alar. 18^ lin. (=39 mill.). 

 Hab. Japonia (in Mus. auct.). 



Evidently allied to P. varia, ami perhaps scarcely more than a 

 form of that species. The insect, however, is more robust and 

 rather larger; the anterior wings broader, more clouded with 

 fuscous, especially in the basal half, which is almost entirely 

 fuscous ; the ground-colour brownish grey, instead of the whitish 

 grey of varia ; the hind wings with a narrow, smoky-fuscous, 

 apical margin. The anal parts are similar to those of varia, 

 only that the lateral lobes seem to be larger and more quadrate. 



I have one female example, from Hakodadi. 



Holostomis, Mannerheim. 



Holostomis Melaleuca, n. sp. H. atra, nitida. Pedes abdomen- 

 que sordide nigri. Alee anticae pallide stramineae, punctis nigris sat 

 dense conspersae ; posticae albae, maculis duabus costalibus ante apicem 

 ornatae, late fusco-limbatae ( S ). Long. corp. 7 1 lin. ( = 15 mill.); 

 exp. alar. 24 lin. ( = 50 mill.). 



Hab. Japonia (in Mus. Brit.). 



Head and thorax deep shining black (antennae broken) : palpi and legs 

 dull black with a greyish tinge. Abdomen dull black : a long trian- 

 gular superior median lobe, shining black, directed strongly down - 

 wards, notched at the acuminate apex, and bearing, before the apex, 

 a needle-shaped process on either side : penis long, flattened, awl- 

 shaped, testaceous (there are also two small testaceous processes which 

 apparently belong to the app. sup.). 



Anterior wings very pale straw-colour, rather densely irrorated with 

 small black spots, some of which are confluent and form reticulations ; 

 two larger costal spots near the apex, some larger spots towards the 

 inner margin ; the apical margin regularly spotted ; veins pale, except 

 where they traverse the black markings. Posterior wings white, 

 subopaque ; a large wedge-shaped black spot on the costal margin 

 above the discoidal cell, the point nearly reaching it ; beyond this, 

 nearly at the apex, a second large, irregular, black spot ; one or two 

 small black dots near the middle of the costa ; apex and apical mar- 

 gin broadly fuscous, with a semilunate pale straw-coloured mark on 

 the extreme margin in each apical cellule ; veins pale.
