Excerpt from Bulletin of the Museum of Comparative Zoology, Harvard University, 1964-1965, Vol. 132
Several brief surveys of the biology of the Bethylidae have have published (wheeler, 1928; Nielsen, 1932; Clausen, 1940; Yamada, and the time does not seem ripe for a full-scale reconsideration of this subject. Under each of the genera treated in the present paper, I have presented a few notes on the life histories as well as references to the more significant sources of information. I am hopeful that this synopsis will stimulate work ers to fill in some of the very many gaps in our knowledge of the life histories and behavior of these wasps. A few of the more significant general features are outlined in the following para graphs.
