*As the enlargements on the third leg of clypeatus are sometimes incon¬ 
spicuous, it is taken out here as well as under 5._ 
t Americanus includes three varieties from the same locality; the first has 
a wide iridescent clypeus, sometimes white, sometimes darker, and a bifurcate 
tibial apophysis on palpus; it has no red hairs on legs. The second, which 
Mr. Banks described as speciosa, and which he thinks is a distinct species, 
has a simnle apophysis, a white clypeus, falces scarlet at base and red hairs 
on first legs; and the third has an iridescent clypeus, a simple apophysis, and 
red hairs on first and second legs.
