SYNOPSIS OF NORTH AMP:RICAN SYRPHID^. 107 



With these two specimens were several others, all males, agreeing 

 closely, except that tlie metallic color of tlie alxlomeii is more exteusive. 

 Two other males have the spots ou the fourth segment coalesceut and 

 the femora less black toward the base. One male has the l^ice distinctly 

 blackish on the tubercle and oral margin; the abdomen deep black, 

 with the three narrow cross bands all interrupted; the femora almost 

 wholly black; .and the tibiae and tarsi much darker than the male first 

 described; the hypopygium also in large part black. Another male 

 differs from the first only in the bands being narrower and all interrupted. 

 All tbese differences are probably only individual. Other males re- 

 sembling these, but with the hind coxse and the legs wholly yellow, 

 may be specifically different.
