face of the propodeum. Punctures on the propodeum 
smaller but continuing in abundance. Wings clouded, 
stigma and nervures black. First segment of the abdomen 
with a recurved hook, segment 2 with a minute hook at the 
base. Pygidium grooved above on the apical half. 
Holotype. — Sacramento, California, August 25, 1916 (L. 
Bruner), $. 
Dr. J. Chester Bradley mentioned this species, of which 
he had a broken specimen, in a paper on the North Ameri- 
can Myrmosidae (Trans. Amer. Ent. Soc., xliii, p. 251). 
He did not name and describe the species, due to the fact 
that the head was lacking on his specimen. 
Myrmosa bradleyi may be easily separated from Myr- 
mosa unicolor Say by the difference in size ( bradleyi 11 
mm., unicolor 8 mm.), in the much darker wing color of 
bradleyi, and in the difference in the coloration of the 
pubescence.
