of setae and on the apical half, 3 crenulate whorls, the distal 2 

 rudimentary ; apically an irregular group of stout, curved, chitinous 

 spines ; terminal segment reduced, narrowly oval. Palpi ; the first 

 segment stout, with a length about twice its diameter, the second 

 about three-fourths the length of the first, narrowly oval, the third 

 a little longer and more slender and the fourth longer, strongly 

 flattened, dilated. Mesonotum dark brown. Scutellum reddish 

 brown. Abdomen a variable brown, the segments narrowly mar- 

 gined posteriori}^ with dark brown. Wings hyaline, costa light 

 brown, subcosta joining costa near the basal half, the third vein 

 just before the apex, the fourth just beyond the apex; the fifth 

 unites with the posterior margin near the distal third, its branch 

 at the basal third ; crossvein at the distal third of subcosta. Legs 

 fuscous yellowish ; claws long, stout, strongly curved, simple, the 

 pulvilli longer than the claws. Genitalia ; basal clasp segment stout, 

 obliquely truncate ; terminal clasp segment stout, slightly swollen 

 near the middle, very broadly rounded apically ; dorsal plate short, 

 broad, broadly rounded. Harpes with an apical group of 5 or 6 

 short, stout, recurved spines. (Plate 13, figure 3.) 



Female. Length i mm. Antennae thickly haired, fuscous yel- 

 lowish ; II segments, the fifth subsessile, the enlargement cylindric, 

 with a length one-fourth greater than its diameter ; subbasal whorl 

 sparse, the subapical band of setae short, scattering, covering the 

 distal half ; terminal segment produced, slightly constricted near 

 the middle, broadly rounded apically. Mesonotum dark brown. 

 Scutellum fuscous yellowish, postscutellum dark brown. Abdomen 

 fuscous yellowish, dark brown distally. Legs light yellowish 

 brown. Ovipositor short, the terminal lobes probably triarticulate.

This species was taken on tick trefoil, D .e s m d i u m grand- 

 i f 1 o r u m , at Albany, N. Y., July 17, 1906. 



Female. Length i mm. Antennae extending to the base of the 

 abdomen, sparsely haired, dark brown, fuscous basally ; 1 1 seg- 

 ments, the fifth pyriform ; the last two segments fused, the distal 

 one subfusif orm. Palpi ; the first segment stout, rather long, 

 swollen distally, the second a little longer, more slender, the third 

 fusiform ; face dark brown. Mesonotum dark brown, submedian 

 lines indistinct. Scutellum reddish brown, postscutellum and ab- 

 domen fuscous yellow, the latter dark brown apically, sparsely 

 clothed with pale yellowish hairs. Wings hyaline, costa light brown, 

 subcosta uniting with the margin at the basal third ; halteres yel- 

 lowish basally, fuscous apically. Legs a nearly uniform straw 

 brown ; claws long, strongly curved, apparently with a short, stout 

 tooth basally. Ovipositor short, the terminal lobes with a stout 

 basal subauadrate portion and a distal narrowly oval lobe. Type 

 Cecid. 617.
