BIOLOGICAL NOTES ON CUBAN WASPS AND THEIR 
PARASITES 
By Richard Dow 
The material for the following notes was collected in 
Cuba during August and September, 1930. Through a 
scholarship from the Atkins Foundation, I was enabled to 
spend nearly five weeks at the Harvard Biological Labora- 
tory near Cienfuegos, Santa Clara. The laboratory is 
located on the Atkins sugar estate, Central Soledad, and 
the situation is ideal for this sort of work. 
I wish to thank the following people who have assisted 
me by determining material : Professor Nathan Banks, 
Mr. H. S. Barber, Dr. A. G. Boving, Miss E. B. Bryant, 
Mr. R. A. Cushman, Mr. Carl Heinrich, and Mr. J. A. G. 
Rehn. I am also indebted to Mr. S. C. Bruner of Santiago 
de las Vegas, Cuba, for permission to publish his observa- 
tion on C hlorion cubensis , and Professor Joseph Bequaert, 
who has read my manuscript and identified all of the Ves- 
pidse. Although the synonymy of these wasps is more or 
less tangled, I am using the names which will soon appear 
in a work on the West Indian Vespidse by Dr. Bequaert 
and Dr. George Salt.

I found several nests of this species in a shallow clay 
pit near Belmonte, Central Soledad. They consisted of a
