ovipositor. Legs simple, slender, hairy but without bristles. Calypteres with a prominent fringe. 
Wings rather large, the anal angle broadly rectangular, costa greatly attenuated beyond the third vein, 
auxiliary vein very close to the first vein into which it ends, third vein simple, its pedicel arising before 
the middle of the basal cells, basal cells long, coextensive, nearly as long as the discal cell and lon- 
ger than the anal cell, the discal cell emitting two veins which are the intercalary and the fifth longitudi- 
nal,at most a stump of the fourth vein projecting from the discal cell, anal crossvein reflexed and straight, 
forming an angle of about one hundred degrees with the anal vein, the anal vein weak but extending to 
the margin. 
Tyne species : C. glabricula, Fallen (Pl. 1, Fig. 1 O), Westwood' s designation, a species widely 
distributed over the Northern Hemisphere. The larva and pupa of this species have been described by
