>Mrs. Ellis had the following notes on this variety: '"California specimens of perpunctatus differ in the 

 mesothorax being smoother, the punctures being smaller; basal area of the metathorax with the rim a 

 little sharper in the variety. Two specimens, Pasadena." 



'Mrs. Ellis had pointed out this variety, but a nime now preoccupied wis given. The writer has 

 preferred to designate the variety by a letter only. Mrs. Ellis's notes were as follows: "Variety o is 

 more slender and has the abdomen more metallic and the margins of the abdominal segments less testa- 

 ceous."
