Of the many names proposed for certain more or less apparent groups of 
species in Chrysops, only two or three appear to be worthy of recognition even 
as subgenera. 
Heterochrysops Krober I cannot accept as a valid subgenus. It was proposed 
for the species in which the dark cross-band of the wing has a well-defined 
hyaline spot, or ‘fenestra,’ in the discal cell. This peculiarity occurs in certain 
forms which are not otherwise related, such as Chrysops variegata (de Geer) 
(= C. costata Fabricius) and C. fulvaster Osten Sacken. In some Ethiopian 
species, such as C. brucez Austen, the center of the discal cell is more or less 
bleached, without, however, forming a distinct fenestra. 
Neochrysops Szilady (= Psylochrysops Szilaidy) was defined as follows: 
“Differs from Chrysops by: (1) abdomen not tomented; (2) tibiae all spindle- 
shaped, long, cylindrical; (3) antennae almost as long as head and thorax 
together, basal joints stick-shaped, long, cylindrical; (4) dorsum of thorax 
provided, before the scutellum, with a light-colored hair-wreath.”’ Species with 
this combination of characters are found in the Oriental and Ethiopian Regions 
only and seem to form a fairly natural group, perhaps of subgeneric rank. Since, 
however, the group includes Chrysops longicornis, the genotype of Kleineana 
Enderlein, it should be known under that name which antedates Psylochrysops. 
Ziemannia Enderlein was based entirely upon the shape of the eye in the 
male, the facets being all about of equal size and the eyes touching each other 
in one point beneath the anterior ocellus. This peculiarity is not, in my opinion,
