A small genus of Holarctic and Ethiopian crane-flies, having sev- 

 eral species within our limits. The adults occur in humid to rela- 

 tively dry open Avoodlands, in the soil of which the larvae live. The 

 coloration of the scape of the antennae appears to vary within the 

 limits of a single species from yellow to almost black. 



Key to Species 

 (Based in part on male characters) 



1. Wings with a strong reddish brown or fulvous tinge; Rs conspicuouslv 



longer than cell 1st M.y, male hypopygium (Fig. 39, E) with the lateral 

 tergal arms acute at tips ; gonapophyses covered with short points so as 



to appear mace-like germana 



Wings not strongly fulvous, tinged with grayish to pale yellow; Rs approxi- 

 mately equal in length to cell 1st M-, or but slightly longer {winneniana) ; 

 hypopygium not as above 2 



2. Fore femora extensively blackened, the bases restrictedly pale; remaining 



femora more narrowly blackened at tips 3 



Femora at most blackened only at extreme tips; in most species uniformly 

 pale '. 4 



3. Costal fringe of wings ( S) long and conspicuous sobrina 



Costal fringe of wings ( S) short and dense megaphallus 



4. Tips of femora narrowly blackened or strongly infumed ; male hypopvgium 



with outer margin of outer dististyle smooth (Fig. 39, G, K) 5
