A study of this complex of wasps will be published elsewhere. 
Two species of Nyssonini, which are cleptoparasites of gory- 
tine and larrine wasps, were encountered at Talparo. Three fe- 
males of Zanysson dives (Handlirsch) were captured flying low 
over the floor of the sandpit and walking on the surface of the 
sand exploring holes or irregularities, but were not seen to enter 
nests. Zanysson is a genus known to attack Tachvtes, and it may 
well be that Z. dives is a parasite of T. fraternus. A male proba- 
bly of Epinvsson zapotecus (Cresson) was also taken in the sand- 
pit. Several members of this genus are known to be parasites of 
Hoplisoides, and it seems likely that E. zapotecus parasitizes one 
or other of the Hoplisoides species nesting at Talparo. 
Acknowledgments 
1 am indebted to Professor R. M. Bohart for identifying the 
wasps. Dr. R. G. Fennah kindly named the Fulgoroidea, Profes- 
sor W. D. Funkhouser, Dr. Louise M. Russell and Dr. P. S. 
Broomfield the Membracidae, and Dr. R. J. Gagne the Spilogona 
sp. The wasps and prey (except for Hoplisoides umbonicida ) 
have been deposited in the Museum of Comparative Zoology, 
Flarvard University. I am grateful to Professor H. E. Evans for 
depositing this material on my behalf and to Ms. Margaret K. 
Thayer for providing me with data relating to the specimens.
