S0LEN0BIA SUIFUNELLA. 183 



broad, 11mm. -13mm., with rounded apex, whitish-grey with a yellowish 

 tint, distinctly reticulated with brown-grey, a darker spot on the trans- 

 verse nervule and at the margin, unicolorous fringes. ? yellow- 

 brown, snow-white anal tuft, 4mm. (Heinemann). 



Comparison of S. wockii with S. inconspicuella. — Before S. uoclcii 

 was recognised as a distinct species, Hofmann observed {Bed. Ent. 

 Zeits., iv., p. 51) that examples sent from Wocke and captured at 

 Breslau were possibly to be referred to S. inconspicuella. Of the six 

 specimens examined he notes that three have the origin of nervures 4 

 and 5 of the hindwings separate, and inner part of the middle cell but 

 little longer than the outer, while in the other three, nervures 4 and 5 

 start from one point, and the inner part of the middle cell is consider- 

 ably longer than the outer. They differ only from 8. inconspicuella in 

 their somewhat superior size, and in having the inner part of the 

 middle cell always longer than the outer. The female is entirely clear 

 yellowish, with small dark grey dorsal spots and white anal tuft. 



Case. — The male case is 2f " long and §' " wide, cylindrical, 

 narrowed at both ends without distinct edges, the female case is almost 

 4'" long, flat beneath with distinct lateral and dorsal edges, overlaid 

 with fine particles of sand and lichen ; it is earth-brown in colour 

 (Heinemann) . 



Time of appearance. — The larvae in March on tree-trunks, imagines 

 in April, in woods about Breslau (Wocke) . Larva? on rocks in woods, 

 the imagines bred freely at the commencement of April, at Lahr 

 (Reutti), April 4th, 1860, at Breslau (Wocke teste Durrant), June 

 28th, 1875, at Weissenstein (Zeller teste Durrant). The latter date 

 must be very exceptional. 



Distribution. — Gekmany: Breslau (Wocke), Silesia (Frey), Berlin (Heine- 

 mann), Lahr (Keutti teste Hofmann). Switzerland: Engacline (Frey coll.), 

 Oberalbula — Weissenstein (Zeller). 



SOLENOBIA SUIFUNELLA, Christoph. 



Synonymy. — Species : Suifunella, Chris., "Bull. Mosc," lvi. (2), no. 4, pp. 430- 

 432 (1881). 



Original description. — $■ , 6-9mm. :;: Capite villis griseis incrassato, 

 corpore fusco, albide-griseo-villoso. Alis anticis acutiusculis griseo- 

 fuscis, albidescano reticulatis ; vena transversa obscufa incrassata. 5 

 fusca, lana anali albida, 9mm. long., 3mm. lat. Der Sackkommt dem 

 von triquetrella, F. R., am niichsten, ist aber noch breiter unci dreikantig. 

 Er ist mit feinen Pflanzentheilen und Sand dicht bedeckt und von 

 Farbe schwarzbraun. Der weibliche Sack ist etwas grosser, 10mm. 

 lang und 4mm. breit und hat weniger vortretende Kanten (Christoph, 

 Bull. Mosc, lvi., p. 430). 



Comparison of S. suifunella with its allies. — It is near 8. wockii 

 but always larger and has less pointed wings. In wing-expanse it 

 equals 8. clathrella (Christoph). 



Case. — The case comes nearest to that of S. triquetrella, F.v.R., 

 but is broader and triangular. It is thickly covered with fine pieces 

 of plant dSbris and sand and is of a black-brown colour. The ? case 

 is somewhat larger, 10mm. long and 4mm. broad, and has less promin- 

 ent angles. 



* This, and the measurements of some other species, only gives the expanse of 

 one win''.
