Dear All,            Nov 2, 2006
    I have a small Syrphid (my number A1171) that keys out to _Eumerus_, 
but M1 does not have an external spur, as required in Nearctic Diptera 
couplet 56, and the inflated hind femur (length/width in side view of 
~4) has strong spines only along an anteroventral ridge on the distal 
1/3 as opposed to also having posteroventral spines near the apex.

    The hind tibia is stout and bowed, with the concave side facing the 
femur, and is dark brown with a yellow band in the middle that registers 
with a yellow band on the mostly brown femur. The first hind tarsomere 
is long and inflated relative to the other tarsomeres.

    Does any of this ring a bell with anyone ? Is there perhaps a 
recently introduced _Eumerus_  that doesn't quite fit the 1987 key ?

Yours truly, Dve Webster, Kentville
