Cells provisioned with one or more cicadas are dug for a short dis- 
tance from the main tunnel. An egg is laid in each cell and it is then 
sealed up. The wasp larva develops rapidly, spins a cocoon, and over- 
winters in this stage within its cell. 
Larra analis F. attacks the northern mole cricket (@ryllotalpa 
hexadactyla), and is found over most of the United States east of 
the Rocky Mountains. Its biology was studied by Smith (382) in Lou- 
isiana, The adult insect is about 5% inch long, black, with dark, brown- 
ish-black wings having shining bronze reflections. At Baton Rouge, 
La., there are at least three generations a year, with most of the adults 
present in the field in June, August, and October. The wasps feed 
on various nectar-producing plants. The females catch most of their 
victims while the mole crickets are occupying surface burrows. When 
contact is made the mole cricket fights desperately with its forefeet, 
but is soon subdued with stings applied about the junction of the 
abdomen and thorax. In contrast to the effects of the stings of other
