OUR UTTER IGNORANCE. 51 



been bred in the south of France, cannot we complete our 

 knowledge of the genus by breeding Ulicicolella ? 



Opostega salaciella, auritella, crepusculella, re- 

 Li QUELL A and spatulella. — As already noticed, p. 42, 

 Auritella was once bred from a flower stem of Caltha 

 palustris. A larva mining in a Caltha leaf, which I re- 

 ceived from Lord Walsingham as being probably that of an 



Opostega, was carefully figured, but produced a Cnc- 



phasia subjectana I 



Nepticula quinquella. — Never yet bred. The first 

 time I met with the insect it was plentiful on the trunk of 

 an oak tree at West Wickham, so that I should suspect the 

 larva to be an oak-feeder. 



Trifurcula atrifrontella. — The perfect insect is so 

 rare with us that we have not had sufiicient opportunities of 

 learning what plant it frequents. Herr Glitz, of Hanover, 

 writes me that the larva of Trifurcula immufidella burrows 

 under the bark of broom, is full fed in April or early in May, 

 and assumes the pupa state within its burrow, the imago not 

 appearing before the middle of July. 



Bohemannia quadrimaculella. — As this larva has 

 hitherto escaped us, and as the insect only occurs, I believe, 

 in wet places, is it possible that the larva can feed on some 

 water plant ?
