Dark borders of intermediate praescutal stripe broad, restricting 

 the stripe itself to a narrow vitta. Male hypopygium with upper 

 process of inner dististyle expanded, more or less adz-shaped; ninth 

 tergite, apex (Fig. 29,1). S. L. 13-14 mm.; w. 14-15 mm.; an-

The fragilis or inarm oraia group. 



Antennae of moderate length; scape and pedicel yellow; flagel- 

 lum uniformly brownish black or black, not or scarcely bicolored. 

 General coloration gray, the praescutum with four entire brown 

 stripes. Wings with cephalic margin of cell 1st Mo (second section of 

 3/1+2) often arched, narrowing cell ^5. Male hypopygium small; 

 eighth sternite often modified. 



A small group of chiefly autumnal crane-flies. Of the local spe- 

 cies, three {ne'buUpeQinis, pJwroctenia^ productella) have the eighth 

 sternite modified; two {fragilis^ nebulipennis) have the outer disti- 

 style blackened and dilated at base. 



Key to Species 



1. Radial cells beyond cord not brightened; dark pattern of wings obsolete or 



nearly so insignifica 



Bases of cell R2 and usually also of R^ brightened by whitish; dark pat- 

 tern of wing evident 2 



2. Size very small (wing, $, less than 9.5 mm.) ; cell Sc and outer half of cell 



C darkened , . perparvula 



Size larger (wing, $, 10.5 mm. or more) ; cell Sc darkened (except in igno- 

 bilis), cell C clear ' 3 



3. Male hypopygium with basistyle produced caudad into a slender lobe (Fig. 



29, O) productella 



Basistyle not produced 4
