blue-green species in Southwestern Utah, Southeastern 
Nevada and Northwestern Arizona, in addition to Mojave

Acanalonia concinnula Fowl. The writer took a male of 
this species at Venice, Florida, July 27, 1927. This example 
agrees with China’s recent drawings and has the brown 
stripe on the suture. It appears to differ from fasciata in 
a number of characters.
