These are described as the male and female of one species on 

 account of the fact that they resemble each other in general appear- 

 ance, and because of the peculiar sculpturing of the second sternite 

 in both sexes. Scdbra and fuHna are the only other species that 

 have the second abdominal sternite sculptured in this manner. As 

 far as is known at present scahra is limited in its distribution to 

 Uower California. Furina is very close to eminentia but is known 

 only from Douglas, Arizona. The male of eminentia is quite re- 

 markable on account of the sculpturing of the second sternite, and 

 by having the posterior trochanters produced at the apex within 

 into a prominent blunt tooth. The female may be distinguished 

 from scdbra by the fact that the metapleura, propodeum, first ab- 

 dominal tergite, and basal margin of the second tergite are sparsely 

 clothed with black hairs, while in scahra the entire insect is clothed 

 with pale hairs except for a basal median spot on the second tergite.
