and was probably introduced about 1884 in pear stock from France 

 or Germany. At first it was identified as probably anxius Gory or 

 acutipennis Mannerheim, but during the latter part of the same 

 year it was identified by J. B. Smith as sinuatus, a European species 

 not before recorded from this country, but which is very injurious 

 to pear trees in Europe. The " Sinuate pear-tree borer " has been 

 adopted as the common name for this pest by the Association of 

 Economic Entomologists.

 shining, uniformly dark blue to greenish blue, and sometimes with

 elevated, and broadly, feebly emarginate in front; antennae extend-
