Excerpt from The Clover Root Borer The species was first described by Marsham (31, p. 57) as obscuras in the genus Ips De Geer, in 1802. The first description to be ao companied by biological notes was that of Muller in 1807, who described it as trifolii in the genus Bostrichus of Fabricius, according to the title of his paper. Schmitt in 1844, published descriptive and biological notes on Muller's species as Hylesinus trz'folii Muller. Chapuis (7, p 231) in 1878 placed Muller's species in the genus Hylastes (erichson), and was to lowed in this classification by Eichhoff 97) in 1881. Bedel (3, p. 390) in 1888 erected a new genus, Hylastinus. For Marsham's species (obscures) and considered it syn onymous with trifolz'i Muller. Hagedorn (17, in 1910 made Hylastinus a subgenus of Hylastes and (fid not recognize Mar sham's species, but retained the name tmfolti Muller. Reitter (36, p. 280) in 1916 retained the genus Hylastinus and recognized the syn cunny of trifolii with obscuras and also listed Hy. Crenulatus Duft. As a synonym. The species was listed with descriptive notes by Swaine 9) in 1918 under the name Hi/lasti'nus obscurus Marsham. The more important synonymy is as follows.

"The importance of red claver (Trifolium pratense) as a forage crop; growing concern about both seed and hay yields; the failure of almost continuous research on varieties, seed setting etc. to greatly improve the situation in Quebec, and preliminary surveys indicating a very high percentage of two year old plants infested by the clover root borer (Hylastinus obscurus (Marshem)), gave rise to these investigations. It has been generously supported by a grant-in-aid for the purpose, from the Quebec Agricultural Research Council to Dr. Frank Morrison." --
