Soochovv, China (N. Gist Gee, 121). U.S. Nat. Museum. 



The abdomen has little of the long loose hair so con- 

 spicuous in A. albicrus. Among the Japanese species, this 

 falls nearest to A. ■prcecocijormis, Ckll., which is larger, with 

 shining clypeus and chestnut-red stigma. The cheeks are 

 broader and flatter in A. delicahda. From Soochovv also 

 comes Nomia chalybeata, Smith [N. Gist Gee, 140).
