2G4 [October, 



In spite of its want of thoracic legs, it is able to crawl about in 

 its case, and even to climb up in a slow and laborious manner a vertical 

 surface. Stretching the thoracic part of its body out of the case to its 

 full extent, it reaches upwards and spins a crossbar of many threads to 

 the surface of the object, when, contracting its body, it draws up the 

 case to the silken bar ; and then goes through the same process again. 

 Thus, in this measured way and making step by step its own ladder, it 

 will mount the slippery sides of a glass vessel. But how does it, without 

 the aid of legs, retain its hold of the old rung whilst spinning a fresh 

 one ? The only hypothesis I can frame is, that it fastens the case to 

 the rung by a thread just strong enough for support, but not so strong 

 that it cannot be broken by the muscular effort of the animal.

DESCRIPTION OF TINAGMA BETULM, n. sp. 

 BY n. T. STAINTON, F.E.S. 



Exp. al., 2| — 3 lines. Anterior wings dark grey, with a slight 

 bronzy gloss, a white spot on the inner margin near the base (sometimes 

 indistinct), and a large white spot (rather triangular) on the inner 

 margin beyond the middle ; the anal angle of the anterior wings seems 

 more produced than in the allied species, and hence the slope of the 

 hind margin is much less oblique. 



T. grisescens from Palestine (Tineina of Syria and Asia Minor, p. 51) differs by 

 the anterior wings being not glossy, and with numerous white atoms in the apical 

 half.

SOME REMARKS ON THE GENUS XTLOPRILUS, WITH DESCRIP- 

 TIONS OP TWO SPECIES FROM JAPAN. 



BY G. C. CHAMPION, F.Z.S. 



Having recently described no less than thirty-five species of 

 Xylophilus from Central America (Biol. Centr.-Am. Col., iv, 2, pp. 166, 

 et seq.), and made some remarks on the genera formed at its expense, 

 I now propose to make some additional observations on the genus as 

 a whole, after a comparison of these American species with numerous 

 others from Europe and Japan. 



Xylophilus (with PhytohcBnus, Euglenes, Aderus, Anidorus, and 

 Olotelus) is, by most authors, European and American, included in
