 Similar to A. fulvi(juht, but cheeks streaked with brown, instead of being 

 plain butt'; speculum metallic purple instead of green ; the general etl'ect of tho 

 coloration mottled rather than streaked, and the lighter markings in general 

 " pale buff or Isabella color" instead of a rich, deep buff. Hab. Northern Mexico

(11.) Page 127, a'. Ardetta is now recognized as a good genus, and the North 

 American species therefore known as A. exilis and A. neoxena. The latter has 

 become better known, most of tho specimens taken having been found in 

 Ontario. The sexes of this species, which is exceedingly distinct, appear to 

 be essentially alike in coloration.
