This species was reared February 1, 1904 by Mr M. A. Knicker- 

 bocker from Baccharis and sent to the Bureau of Entomology, 

 United States Department of Agriculture. Apparently the same 

 species was taken in Alameda county, California, on B. pilularis 

 in September, presumably in 1885, and others reared from the 

 flowers of this plant April 25, 1886.

 each extremity; terminal segment greatly pro- 

 duced, cylindric, with a length about four times 

 its diameter, tapering, obtuse. Palpi; a single
