scape obviously greater than the transverse diameter of an eye. Pronotal 

 collar sharply margined except just at the sides. 



Fore wing with basal vein normally with 6 to 13 hairs, fewer in dwarfs, 

 which have the gaster longer than head plus thorax phalaridis Graham (p. 623) 

 Either the tip of the hypopygium is situated at nearly or quite half the 

 length of the gaster ; or else the fourth funicular segment of the antenna is 

 not longer than broad. Pronotal collar often less sharply margined . . 9 



(8) Antenna with fourth funicular segment 1-3 to 1-5 times as long as broad, fifth 

 very slightly elongate or quadrate. Gaster 1-4 to 1-7 times as long as 

 broad, at most as long as the thorax ; distance from base of eighth tergite 

 to tip of gaster less than the length of the basal tergite. Femora usually 

 fulvous to red, occasionally infuscate basally ; mesoscutum with close- 

 meshed reticulation, hence rather dull ; basal vein of fore wing with four to 

 ten hairs. Large species, length 3-0 to 4-2 mm. . harmolitae Boucek (p. 622)
