What then are our conclusions ? We can hardly claim C. ednm 

 as a permanent resident, although we suspect that it may, at times, 

 exist in this country for successive years, but this is a point on 

 which we need more direct evidence. Be that as it may, its habits 

 when here, the circumstances surrounding the times of its greatest 

 abundance, even the features of its variation, all seem to point to 

 the migratory propensities of the species, and, so far as concerns 

 Britain, its distant origin, but here again we want to know 

 something more definite. Even the negative evidence supplied 

 by McLachlan and Meldola in 1877, had its significance, and now 

 that so many of our members are in the habit of making excur- 

 sions into the adjacent districts of the pahearctic area, is it too 

 much to hope that they will put on record their experiences of this 

 interesting species, and thus, in co-operation with those whose 

 energies are confined to this country, assist in the definite elucida- 

 tion of one of the most interesting problems of the British 

 Lepidopterous fauna ?
