TALEPORIIDAE. 199 



so that it has a somewhat trigonal appearance. The case is soft, the 

 " parois " of it slightly thickened, greyish-black, with some very small 

 particles of earth on its surface. 



Pupa. — The pupa appears to be fastened in this spacious case 

 chiefly at the tail. It is somewhat glossy, yellow-brown in colour, and 

 protrudes far on emergence (Zeller). 



Food-plants. — Lichens growing on walls (Treitschke) , on old fences 

 and walls (Bruand), on Genista (Her rich-S chaffer), lichens on sloe- 

 bushes (Mann). 



Time of appearance. — Cases in April and May, the imagines in the 

 latter month (Hartmann), June (Duponchel), cases in May and June, 

 imagines in July (Schaum). 



Distribution. — Austro-Hungary : Buda (Treitschke), Vienna (Mann). 

 ? Finland (Erschoff). France : An alpine species — Gueret (Sand), Savoy 

 (Ghiliani). Germany: South Germany (Herrich-Schaffer), Munich (Hartmann), 

 Nieder-Sachsen (Treitschke). Italy: Piedmont (Ghiliani). Eussia : St. Petersburg, 

 ? Esthonia (Erschoff and Feild). Scandinavia : Sweden — Scania, Gothland, Upland 

 (Wallengren). Switzerland: Locarno (Chapman). 



Nearctic species of Solenobia. 



Only one North American species of Solenobia (in sensu strictu) appears 

 to have been named, viz.,walshella, Clem., and there are in the " Walsing- 

 ham " collection two males bearing this name which are regarded by 

 Durrant and YValsingham as representing two species. The one con- 

 sidered "to be the true ivalshella is of the size of IS. triquetrella, but 

 quite distinct, more mottled with brown than 8. wockii, and not such a 

 smooth-looking species. The other (with a case) is close to S. trique- 

 trella. The name ' walshella ' probably does duty for a large number 

 of species (and perhaps genera). Clemens describes walshella as with- 

 out ocelli. Lord Waisingham and I have carefully studied both 

 specimens, and consider them both to be Solenobia in your sense "

Family : taleporiidae. 



This family is very closely allied to the Solenobiids, from which, 

 however, it may readily be distinguished by the presence of ocelli in 

 the male imagines, and by the position of the larval tubercle ii which 

 is placed directly behind i on the abdominal segments. In the possess- 

 ion of ocelli this family comes nearer to the Diplodomids and the 

 general larval habits are not at all dissimilar. The yellow speckling 

 of the male Taleporia tubulosa is not at all unlike that of Diplodoma 

 herminata, but the Taleporiid females are almost wingless and this affords 

 a sharp separating line between the two families. There appear to be only 

 two genera yet recognised in this family — Bankesia and Taleporia — 

 the former thinly scaled, strongly marked with the characteristic pale 

 Solenobiid specklings (here very large) but heavily mottled with darker 

 markings. In many respects Bankesia appears to form a strong con- 

 necting link between the Solenobiids and Taleporiids, the superficial 

 facies tending to the former, whilst structurally it belongs to the latter, at 

 the same time the imagines, like those of Solenobia, appear in the early 

 spring. The darker-coloured imagines of Taleporia (tubulosa, politella, 

 &C.) are more thickly scaled, have the characteristic Solenobiid speck- 

 lings much reduced or absent, and appear in the early summer. The eggs 

 are laid by the almost wingless females (which rest on the outside of the
