new species He ai)peara, from his remarks, to have had a more inti- 

 mate acquaintance with the species o£ this genus nearly forty years 

 ago than we can boast of now, or indeed at any time since. For many 

 years we have heard nothing of the cases which he used to find on 

 large stones of millstone grit on the moors (in North Wales ?), which 

 were understood to produce S. triquefrella, and further investigation 

 will be required before we can satisfactorily ascertain whether this 

 last is actually a native species or, so far as this country is concerned, 

 merely s3^nonymous with S. Wockii. Triquefrella, as known abroad, 

 is larger and paler, with the reticulations or latticing very faint and 

 the fore-wings more pointed, much like another Continental species, S. 

 clafhrella, but not so large. 



Heinemann describes S. friquet?'ella with long fore-wings, brownish 

 ash-grey, with broad darker nervures, and dappled abundantly with 

 grey-white spots ; hind-wings blankish ; head small, brown in front ; 

 expanse of wings, 3 to 3^ lines. Female dark brown, with blackish- 

 brown head and thorax, and whitish-grey anal tuft. 



S. inconspicuella he describes as smaller, 2\ to 2| lines expanse, 

 fore-wings narrower, brownish- grey, latticed with wbitish-grey flecks ; 

 margin and cilia dotted with brown -grey. Female smaller than that 

 of S. Wockii, rust-yellow with dark brown head and white anal tuft. 



These details, with the measurements, represent pretty accurately 

 the three species, and appear to confirm the present identification ; 

 but the group is obscure, the species very closely allied, and further 

 information upon all of them is much to be desired, 



It may be desirable to point out that the species named S. tri- 

 quefrella by Fischer von Boslerstamm cannot well be that referred to 

 above, nor indeed a member of the present genus, since it is described 

 as having pectinated antennae. Probably it represents one of the 

 species of Epichnopteryx among the Psychidce. 



I feel certain that the Lancashire Entomologists used at one time 

 to find Solenohin cases in numbers by turning over the loose blocks of 

 stone on the moors or hill sides ; and if those of the present day will 

 brace themselves, like their predecessors, to the physical labour of 

 turning over the loose blocks, there is little doubt that they will be 

 rewarded. To obtain males it will be necessary to secure the smaller 

 cases, unless the moths can be captured. It is hardly likely, however, 

 that these will fly so readily on an exposed moor or mountain side as 

 in a sheltered spot at the edge of a Worcestershire forest. Possibly 

 it may be desirable to imitate the Midland workers hj gefting up early 

 in the morning.
