Elis (Mesa) tricolor longiceps Turner. 
The black thorax and abdomen, red head, and dark wings 
make it very easy to recognize this striking species. 
The females agree exactly with Turner’s description of the 
subspecies, and the males differ from his description of Mesa 
crassepunctata as follows: Head distinctly narrowed behind the 
eyes; pronotum without obscure transverse strix, but polished 
and very sparsely punctured; first tergite longer than the 
second; abscissa of radius not one-fourth shorter than the 
third; first recurrent received by the second cubital just before 
the middle; length, 16 millimeters. The males may have been 
described by Bingham under the name Myzine dimidiaticornis, 
but the second abscissa of the radius is hardly as long as the 
third.
