 A, porterx is near top of hole with jaws spread in a threatening 

 manner, and head blocking the entrance. Wasp jumps at bee in 

 hole, then flies away. Back and strikes at abdomen of bee as 

 the bee backs out of hole. Bee and wasp leave, fighting. Wasp 

 soon returns, alights near hole, tapping it with her antennae. 

 Enters and is pulling out one larva as A. porterx returns. Bee 

 strikes and tries to bite wasp with her mandibles, a number of 

 times. The wasp flies with larva and drops it 10 inches from 

 hole after which she flies away. Bee then goes inside. \Vasp 

 returns but pays no attention to larva which she dropped but 

 comes to hole and looks in for a time. She then flies away.

 out almost at once. Flies a few inches away. Returns. Looks 



in. Goes in. Out and is ready to go in again when A. porterx 

 returns with load of down. She strikes wasp and both fly. The 

 bee follows wasp fighting and striking her while in the air. The 

 wasp circles back to the nest followed by bee, and tries to go 

 into the hole. The bee repeatedly strikes wasp as latter tries 

 to enter. A. porterx drives her away, following her out of my
