290 Mr. R. McLachlan on 



Anal appendices as in N. reticulata ( cJ ) . 



Smuland, Sweden. I received two males from Prof. 

 Stalj one of which he liberally presented to my collection. 



When the wings are closed it has a most deceptive 

 resemblance to small examples of N. ruficrus, only that 

 the colour is more intense. The vestige of yellowish 

 spotting on the costal margin of the anterior wings 

 shows its affinity with N. reticulata and clathrata, with 

 the former of which it agrees almost entirely^ excepting 

 in coloration, which difference is so striking as to pre- 

 clude the possibility of its being a variety, the two exam- 

 ples being moreover precisely similar. 



Neueonia lapponica, Hagen. 



To this species belong the Lapland examples noticed 

 by Zetterstedt under N. reticulata (Insecta Lapponica 

 col. 1061). It differs from both clathrata and reticulata 

 in the pale markings of the fore-wiogs and the ground 

 colour of the hind-wings being whitish instead of orange- 

 yellow : the dark median band of the hind-wings is 

 absent. The legs are entirely pale, as in clathrata. In 

 size it is larger than either species. 



The app. inf. of the $ are produced at their upper 

 edge into a very long curved spine, somewhat as in rufi- 

 crus ; whereas they are blunt in clathrata, reticulata, and 

 8talii. 



It has hitherto been found only in Lapland. 



LIMNEPHILID^. 



Stenophylax algosus, n. sp. (PL XIV. fig. 6) . 



Reddish -brown. Antennce pale brown with yellowish 

 annulations; basal joint fuscous. Head fuscous, with 

 scattered golden hairs ; "palpi reddish-brown. Thorax 

 reddish-brown ; prothorax thickly clothed with golden 

 hairs. Anterior wings moderately long, the apex re- 

 gularly elliptical ; pale gray, thinly clothed with short 

 yellowish-gray pubescence, and regularly sprinkled with 

 small and indistinct whitish dots (four or five of these dots 

 are placed in each apical cell), that at the thyridium 

 being larger and more distinct ; the membrane is finely 

 granulated throughout; neuration fuscous and distinct, 

 the longitudinal veins carrying short blackish-brown 

 hairs ; the discoidal cell scarcely so long as its footstalk ; 

 all the apical cells nearly equal in width ; the first oblique
