FAM. EMPIDID/E 229 
GENUS CLINOCERA, MEIGEN 
Characters. — To this division of the group C/znocera belong those species in which the lower 
part of the head is not produced downward beneath the eyes. The cheeks are thus narrow, and are 
deeply incised, even to the margin of the eye, and thus the sides of the face are entirely separated 
from the lower occiput or cheeks. The pulvilli and empodium are developed except in the subgenus 
Bergenstammia. None of the species has acrostichal or interstitial dorsocentral setule, and except in 
Bergenstammia there are no setulz on the disk of the scutellum. 
The following subgenera are recognized : 
Clinocera, in the strict sense. Lower edge of the face transverse and not excised; discal cell 
rather sharp apically, wings not or scarcely spotted, costal setulz usually minute, stigma wanting or 
faint. 
Tyne species : nigra, Meigen (Pl. 2, Fig. 18). The only species mentioned in the original 
description. Some recent papers, unfortunately including Kertész' Catalogue of the Diptera of the 
world, have adopted Meigen's 1800 name Af/alanía in place ofthe universally known Clinocera, and 
would call the subfamily the A/alantineg. As Meigen mentions no species in this early paper the type 
dates from H endel's interpretation in 1908, reason enough for disregarding the name Atalanta. 
SuBcGENUS HYDRODROMI!A, MACQUART 
Characters. — Lower edge of the face entire and transverse, not notched ; discal cell blunt 
apically, wings more or less obviously spotted on the crossveins and on the forks of the veins but 
without a distinct stigma, costal setulae variable, sometimes an extra crossvein connecting the upper fork 
of the third vein with the second vein and thus producing three submarginal cells. 
Tyne species : H. s/agnalis. Haliday. Macquart included two species in Hydrodromia, stagualis 
and óifunctata, the latter being removed by Mik to his genus Kowarzia. .By elimination, as Coquillett 
noted in 1903, s/agnalis becomes the type of Hydrodromia. | Heleodromia of various authors, based on 
stagnalis, is not the same as Genus 10, Heleodromia, based on immaculata. | Paramesia W esmelii, Macquart, 
which was designated by Coquillett in 1903 as the type of Paramesia, is congeneric with H. stagualis. 
SuBGENUS PHZEOBALIA, Mik 
Characters. — Lower edge of the face with a median excision, the membrane filling the notch 
depressed and more or less carinate; discal cell blunt at the tip, wings spotted as in Hydrodromia, but 
the stigma is more distinct. 
Type species : P. lrinolata, Mik, by Coquillett's designation, 1903. Engel has unnecessarily 
specified P. dimidiata, Loew as the genotype. 
SuBGENUS KOWARZIA, Mik 
Characters. — Face with several scattered hairs, its lower edge incised in the middle, the notch 
filled by a depressed membrane which is more or less carinate; discal cell blunt at the tip, wings not 
spotted, the stigma poorly developed. 
Type species : K. barbatula, Mik, by Coquillett's designation, 1903.
