Female. Length I mm. Antennae scarcely extending to the 
base of the abdomen, sparsely haired, reddish brown; 12 segments, 
the fifth obpyriform, with a length one-half greater than its diam- 
eter ; terminal segment produced, slightly constricted near the distal 
third at the chitinous collar. Palpi; the first segment short, stout, 
irregularly ovoid, the second stout, with a length about one-half 
greater than its diameter, the third about one-half longer than the 
second, more slender, the fourth about twice as long as the third, 
greatly dilated. Mesonotum rather dark reddish brown. Scutellum 
and postscutellum lighter. Abdomen brownish yellow. Wings long, 
narrow, hyaline, costa a light brown, subcosta uniting with the 
anterior margin near the basal half. Legs a variable light yellowish ; 
claws long, slender, strongly curved, with 4 or 5 long denticulations ; 
pulvilli as long as the claws. Ovipositor short, the terminal lobes 
triarticulate, the third segment broadly oval. Type Cecid. 883. 
Prionellus monilis n. sp. 
This species was reared in November 1907 by Mr E. S. Tucker 
from a cage sown with oats. 
Female. Length 1 mm. Antennae extending to the third abdo- 
minal segment, thickly haired, dark brown; 12 segments, the fifth 
with a length one-third greater than its diameter ; terminal segment 
greatly produced, constricted and evidently composed of two closely 
fused. Palpi; first segment stout, broadly oval, the second narrowly 
oval, the third a little longer, more slender, the fourth one-half 
longer than the third. Mesonotum dark brown, the submedian lines 
sparsely haired. Scutellum and postscutellum brown. Abdomen 
dark brown, the basal segments yellowish brown. Wings hyaline, 
costa light brown, subcosta joining the margin at the basal half, the 
third vein near the apex. Halteres yellowish transparent. Legs a 
variable fuscous yellowish, the distal tarsal segments brownish; 
claws strongly curved, denticulate, the pulvilli longer than the claws. 
Ovipositor short, the lobes triarticulate, the third segment broadly 
oval, all sparsely haired. Type Cecid. 1296.

1908 Felt, E. P. N. Y. State Mus. Bul. 124, p. 314 (Campylomyza) 
This species was taken June 26, presumably 1903, by Mr R. P. 
Currie at Kaslo, B. C. 
Female. Length 1 mm. Antennae hardly extending to the base 
of the abdomen, thickly haired, yellowish brown; 12 segments, the 
fifth subsessile, subcylindric, with a length about one-third greater 
than its diameter; terminal segment somewhat produced and taper- 
ing to a rounded apex. Palpi; the first segment greatly expanded dis- 
tally, pyriform, the second a little longer, slender, narrowly rounded 
apically, the third a little longer and more slender than the second,
