22 INSECUTOR INSCITI/E MENSTRUUS 



J. D. H., I macropterous female under willow bark ; Boskydell, Illinois, 

 October 22, 1 908, L. M. Smith, from branch of white oak, 1 brachyp- 

 terous male; Mahomet, Illinois, July 27, 1908, J. D. H., under bark of 

 rotting willow branch, I macropterous female, 4 brachypterous females, 

 and 3 brachypterous males ; Murphysboro, Illinois, November 6, 1 908, 

 L. M. Smith, from bramch of bur oak, 1 macropterous male ; St. Joseph, 

 Illinois, May 25, 191 3, C. A. Hart, from branch of oak, I macropterous 

 female and 3 brachypterous females. (One brachypterous male was 

 taken under apple bark at Vienna, Virginia, November 7, 1 9 1 3, by 

 R. A. Cushman.) 



The closest described North American relative of this species is T. 

 heachi Hinds, which differs conspicuously in having the tube " fully as 

 long as the head." 



I take pleasure in dedicating this splendid species to Dr. H. Karny, 

 of Vienna, Austria, in recognition of his work on this order of insects. 

 He has compared it with 7". ulmi (Fabricius) and found it distinct.
