DiESTRAMMENA UNicOLOR IN NoRTH AMERICA. — I have lately received a 

 female of this East Asian species which was captured in a greenhouse in Chicago, 

 111., from Mr. W. J. Baumgartner. Its congener, marmorata, reported to have 

 established itself in conservatories at Minneapolis, is likewise of Asiatic origin. 

 Both species doubtless owe their introduction to commercial importations of foreign 

 plants, among the wrappings of which they easily secrete themselves. — A. P. Morse.
