attacks, The two creatures rolled and struggled one over the other for a 
good five minutes, the spider dodging and biting and the Pseudagenia 
trying vigorously to sting, and so render its opponent insensible. At 
length the wasp managed to succeed, the spider lay helpless and 
quivering. Then Mrs. Pseudagenia (for it was a female) paraded 
round in a sort of triumph, flirting her head and antenn, and finally 
picking up the spider between her fore and intermediate legs flew off 
to a crevice at the corner of the ceiling. This species, I believe, has 
also two broods during the year. I have found nests in January and 
again in June.
