This species is given on the authority of F. M. v. d. Wulp., who com- 

 pared specimens collected in the vicinity of Quebec. He says : " Dat 

 zij in Canada voorkomt, kann nu als zekerworden aangenomen." The 

 synonymy is given from Schiner.

 Professor Eiley's collection). In one of these specimens the fourth ab-

 tiated and has less of the bronze lustre; in the same specimen the dor- 

 sum of the thorax shows a distinct blue reflection.
