European Trichoptera. 291 



at the base and as long as the third, which is two-sided at 

 the base ; second and fourth shorter, truncate at the 

 base ; fifth acute, scarcely so long as the fourth : posterior 

 wings whitish sub-hyaline, slightly grayish at the tips ; 

 fringes very short, but becoming longer at the anal 

 angle. Legs yellowish testaceous, with black spines. 

 Ahdoinen blackish fuscous, with a grayish line on each 

 side ; the terminal segment slightly reddish, and carry- 

 ing a few short yellow hairs on its dorsal surface. 



Anal appendices. In the c? the dorsal margin of the 

 last segment is slightly rounded and rolled inwards. 

 The appendices are small and little prominent, being 

 hidden in the cavity of the segment; reddish. App. sup. 

 almost completely concealed, appearing to be ear-shaped : 

 app. intermed. moderately long, up-curved: app. inf. 

 short, subtriangular, clothed and fringed with blackish 

 hairs : penis sheatJis short, broad and flattened, carrying 

 a tuft of yellowish hairs at the tips : penis slender, and 

 appearing to be sulcated beneath. 



Expanse of wings, $ , 12^"'. 



Southern Lapland. One male, in the collection of the 

 Stockholm Museum. 



This small Stenopliylax will not agree with the descrip- 

 tion of any of the yet uncertain species in Zetterstedt's 

 " Insecta Lapponica; ^^ nor does it appear to be elsewhere 

 noticed. It belongs to the group of JiieroglypJdcus rather 

 than to that of stellatus. 



Stenophylax alpesteis, Kolenati. 



From the Pyrenees {Rev. T. A. Marshall) I possess a 

 pair of a small StGnophylax, which I cannot separate by 

 any structural characters from specimens of alpestris from 

 Carniola, Sweden, and England, in my collection; yet 

 they have a somewhat difi'erent appearance, probably 

 owing to local influences. The wings show scarcely a 

 trace of pale markings, the pubescence is much less 

 dense, and the veins are very strong and blackish fus- 

 cous, whereas they are weak and pale in the ordinary 

 examples. I give below a description of the S 'appendices 

 of the typical form (from which the others do not differ 

 in this respect), the figure given byBrauer (Neurop. Aust. 

 fig. 49) being scarcely sufficiently correct.
