Five f species and two distinct varieties have now been 
described in this genus. They have all the marked silvery-grey 
or grey area in front of the thorax. 
The species tabulate as follows :— 
a. Legs with apical and basal pale banding. 
Abdomen with basal pale bands and almost 
basal lateral pale spots; ? ungues all 
simple .... gelida. Tbeobald.f 
* American specimens may differ, but I cannot see a single character 
to separate them, and do not believe they are separate. 
f Giles Taeniorhynchus Whitmorei, 1904, is a Leucomyia according to 
Mr. F. Garter, and must be placed here (vide Genus Taeniorhynchus). 
f Two well marked varieties of gelida occur:— 
var. bipunctata Theo.—two dark spots on pale thoracic area, 
var. cuneata Tbeo.—abdomen witk the basal pale bands projecting 
in the middle.
