One or two evident dorsocentrals; abdomen of male more or less silvery

Pholeomyia myopa new species. 



Male. — Very close to indecora Loew, but differing in the structure of the 

 head. The eyes are larger, encroaching on the front and face, the facets are 

 larger, requiring about five to measure the width of the third antenna! joint, 

 whereas in indecora about six facets span the same distance. The front is 

 conspicuously but uniformly narrowed toward the antennae, where it is much 

 narrower than the length of an antenna. The ocelli are close together and 

 small, the ocellar triangle smaller than the third antennal joint. The cruciate
