There is great need of careful observations on and breeding of this 

 and the several closely allied species. To Miss ]\Iary Murtfeldt is due 

 what has been done already in this direction in this group, and with- 

 out her records we should be still more at sea than now is the case. 



What I provisionall}', in common with Miss Murtfeldt and Lord 

 Walsingham, take to be this species is the same as Zeller held to be 

 roseosuffusella^ as is shown by Zeller's authentic specimens in Cambridge 

 and in the U. S. National Museum. It is also what Chambers and 

 Riley thought to be the species, as is shown by the specimens deter- 

 mined by them. This species breeds in Trifolium pratense and is com- 

 mon all over the continent and is also found in the West Indies. 



But Clemens says expressly that roseosuffuseUa feeds in the fruit 

 panicles of sumach.^ 



It is unlikely that the species has both food plants. I have endeav- 

 ored during the last years to breed all jNlicro-lepidoptera found on 

 sumach with this particular question in view, but have not met with 

 any w^iich l)elong in this group. 



Clemens made his statement about the food plant four and a half 

 years after his description of the insect, and has possibly made a mis- 

 take .somehow; but if ever a Gelechild answering his description is 

 bred from sumach, it nmst of course retain Clemens's name and a new 

 name must be provided for the TrifoUwn feeder. 



In the U. S. National Mu.seum are two specimen named by Zeller, 

 one labeled by Chambers, and three by Lord Walsingham, besides 

 numerous specimen from many different localities.
