European Trichoptera. 299 



Wings fuscous, uni(iDlorous, densely clothed witli fuscous 

 pubescence, showing a slight reddish tinge ; fringes 

 very long and dense, brown with a golden rejflection in 

 certain lights : anterior wings slightly acute ; neuration 

 not visible unless the hairs be removed; subcosta join- 

 ing the costa beyond the middle ; radius running nearly 

 to the apex, bent beyond the middle ; discoidal cell long ; 

 arrangement of the veins generally as in S. reducta (vide 

 " Triclioptera Britanniea," pi. vii. fig. 1) ; the three 

 transverse veinlets in an oblique continuous line as in 

 S. reducta ; the longitudinal veins are fuscous, the trans- 

 verse veinlets whitish hyaline. Legs wholly silky silvery- 

 gray ; anterior tibiae with one short and stout spur. 

 Abdomen blackish fuscous, the margins of the segments 

 narrowly edged with whitish, and there is a whitish 

 (probably greenish in life) stripe on each side. 



Anal appendices. In the $ there is a short triangular 

 black lobe in the middle of the dorsal margin of the last 

 abdominal segment, and beneath this another long and 

 slender lobe which is probably the upper penis cover ; 

 app. sup. short and broad, concave beneath, fuscous, 

 fringed with long golden-gray hairs ; (ijp- "]/• short, 

 dilated at the base, the apical portion thinner, crooked, 

 and directed upwards ; in the cavity of the segment is 

 seen a short yellow tubular piece, open at the end, 

 enclosing the short penis (PI. XIV. figs, without a num- 

 ber). In the 9 there are two short superior lobes, longly 

 fringed, very similar to the app. sup. of the $ , and bet- 

 ween these is a longer lobe, concave internally ; the 

 oblique apex of the last segment, seen from beneath, is 

 greenish and shining.

This is evidently closely allied to S. filicornis, Pictet, 

 (Recherch. p. 171, pi. xii. fig. 6), and may possibly be a 

 form thereof. The type sent by Pictet to Curtis has 

 lost its abdomen, and the wings are entirely denuded ; 

 the neuration appears to be the same. The colour of 

 filicornis should be decidedly paler than that of mwsteUa, 

 and Pictet says of the antennae, " d\in fauve clair,^' and 

 of the legs '^rougeatres" (with which the type agrees 

 moderately well) , whereas these parts are delicate silvery- 

 gray in moestella. Perhaps a ? from Zeller's original col- 

 lection, without locality, may pertain to filicornis. S.fusca 

 of Bi-auer is somewhat similar in its uniform dark color- 

 ation, but differs in the annulate base of the antenna).
