Leptura subpvbescens, Kb. N. Z. 180- 
Trigonarthris prorima, Hald. 65. 
T. terminata, Dej. Cat. 
Lake Superior, Missouri Territory, Maine, and Pennsylvania : rare. 
The male is narrower and shaped like L. chrysocoma. This species with the next 
constitutes Dejean’s genus Trigonarthris. They only differ from other Leptura in 
having the intermediate tarsi as broad and as short as the anterior pair. They are, 
however, more dilated in the males, and, moreover, are not alike in all Leptura: for 
these reasons I have thought it more natural to replace these species among the 
genuine Leptura.
