These specimens are all macropterous. They are on the 

 whole soiucwh.al bro.ider between the middle legs than eastern 

 specimens of ornatus, but I have specimens from Ontario which 

 are indistinguishable from them, and considerable variability 

 seems to exist in this regard. It may be that some, or all, of 

 these specimens should be referred to T. crassus Morse, but I 

 cannot regard tliem as specifically distinct from ornatus.
