fuscous apically, the first tarsal segment, the basal two thirds of the second, a 

 narrow basal band on the third and fourth, and most of the fifth tarsal segments 

 fuscous, the remainder yellowish. Ovipositor short, the terminal lobes narrowly 

 lanceolate. Otherwise nearly as in the male. 



Reared from jars containing chestnut and maple bark infested with 

 numerous Miastor americana Felt larvae. Type C. a2150 Y. 



Itonida cincta n. sp. Female. Length 1.5 mm. Antennae nearly as long as the 

 body, sparsely haired, pale yellowish, the segments fuscous basally; fourteen seg- 

 ments, the fifth with a stem one third the length of the subcylindric basal enlarge- 

 ment, which latter has a length nearly three times its diameter; terminal segment 

 produced, with a length six times its diameter, tapering to a subacute apex. Palpi; 

 first segment short, stout, the second narrowly oval, with a length over twice its 

 diameter, the third one half longer, more slender, the fourth one fourth longer than 

 the third, more slender. Mesonotum yellowish brown. Scutellum and postscutellum 

 pale yellow. Abdomen yellowish bro-^vTi, the ovipositor orange red. Wings sub- 

 hyaline, yellowish, distinctly marked with brown, there being a diffuse fuscous 

 area near the basal fourth and extending to the posterior basal angle; another broad, 

 diffuse band extends obliquely across the middle of the wing to the branching of 

 the fifth vein; the apical fourth of the wing is mostly fuscous, except for an oval 

 space near the distal ninth and close to costa, and a similar one midway between 

 the third and fifth veins; an irregular though dark patch Hes near the middle of the 

 wing between the third and fifth veins. Legs banded, dark brown, the tibia with 

 basal and subapical light bands, the posterior tarsi with first segment and the base 

 of the second, third and fourth segments and all of the fifth yellowish white, the 

 anterior tarsi with a broad band near the middle of the second and at the base of 

 the third and fourth segments, the fifth silvery white. Ovipositor about as long as 

 the abdomen, stout, the terminal lobes narrowlj- oval. 



Reared from larvae occurring under oak bark. Type C. 1074. 



Itonida canadensis n. sp. Male. Length L5 mm. Antenna? one half longer than 

 the body, rather thickly haired, light fuscous yellowish; fourteen segments, the 

 fifth ha^^ng the basal part of the stem with a length two and one half, the distal part, 

 with a length three and one half times its diameter. Palpi; the first segment prob- 

 ably subquadrate, the second broadly oval, the third with a length aboiit three 

 times its diameter, the fourth one half longer than the third. Face whitish transpar- 

 ent: Thorax a nearly uniform yellowish transparent. Abdomen a variable pale 

 yellowish, the basal and distal segments pale orange. Wings hyaline, yellowish; 

 costa orange yellow, subcosta at the basal third, the third vein well beyond the apex. 

 Halteres yellowish transparent. Coxaj pale yellowish; femora and tibiae pale j-ellow- 

 ish straw; tarsi mostly a very fight brown, the distal segments somewhat darker; 

 claws strongly curved basally, simple, the pulvilli about half the length of the claws. 

 GenitaUa; basal clasp segment long, slender, terminal clasp segment long; dorsal 

 plate broad, deeply emarginate, the lobes produced lateralh", roundly emarginate; 

 ventral plate long, broad, broadly and roundly emarginate. 



Female. Length 1.5 mm. Antenna; one third longer than the body, sparsely 

 haired, pale yellowish; fourteen segments, the fifth with a transparent stem as long 

 as the cylindric basal enlargement, which latter has a length slightly over twice its 

 diameter; terminal segment produced, with a length three times its diameter and 

 a long, finger-like apical process. Palpi; first segment short, stout, the second with
