“ American Micro-Lepidoptera, by Brackenridge Clemens, M. D.” 
“ Observations on American Tineina, by H. T. Stainton.^^ 
And were referred to Committees. 
The following Communication was read from Baron B. Osten Sacken: 
«Mr. WalstL just communicates me that he bred Lasioptera solidaginis 0. S., 
described by me in these Proceedings (Vol. I, p. 368) in great numbers, from 
the lepidopterous gall on Solidago, and not from the gall of Trypeta solidaginis. 
He also bred the same Lasioptera from exactly similar galls on Vernonia 
fasciculata. 
“ Thus the doubts which I entertained when the above quoted paper was 
written, are now solved. 
“ I may mention here that Trypeta asteris Harris is nothing but a synonym 
of T. solidaginis Fitch, as I have ascertained in Mr. Harris’s collection in 
Boston. Whether this fly really also produces galls on Aster, remains to be 
decided by observation. In Mr. Harris’s manuscript catalogue of his collec¬ 
tion, which is still preserved, he had written originally, opposite the number, 
designating this fly : ‘produces galls on Solidago.’ Later, however, he struck 
out the word Solidago and put Aster, in pencil, in its stead. Although the 
name T. asteris is older, I think that the name of T. solidaginis, as the more 
appropriate one, should be preserved, the more so, as there exists another 
71 asteris of Haliday.”
