A pair taken in the Journey from New York to Cumberland-house. I have 

 excluded the synonyms of Fabricius and Olivier, to which De Jean has added a 

 mark of interrogation, because they both describe the species they call C. amethys- 

 tinus, as blue underneath, of which colour our insect has not the slightest shade, 

 and Olivier's figure 9 evidently belongs to a much smaller insect.
