costa dark brown, subcosta at the basal third, the tliird vein well beyond the apex. 

 Halteres yellowish basally, fuscous apically. Coxa; fuscous yellovWsh. Legs fuscous 

 straw, the distal tarsal segments darker; claws slender, evenly curved, simple, the 

 pulvilli rudimentary. Genitaha fuscous, setose; basal clasp segment long, rather 

 slender; terminal clasp segment long, slender; dorsal plate rather short, broad, 

 triangularly emarginate, the lobes broadly and roundly emarginate, setose apically; 

 ventral plate long, broad, deeply and roundly emarginate; style stout, broadly 

 rounded apically. 



Female. — Length L75 mm. Antennae fuscous, whitish basally; fourteen segments, 

 the fifth with a stem about three fourths the length of the cyhndric basal enlargement, 

 which latter has a length four times its diameter; subapical band scattering; terminal 

 segment slightly produced, basal enlargement fusiform, with a length three times 

 its diameter and apically with a long, slender, irregular appendage. Palpi; the 

 first segment irregular, the second with a length four times its diameter, the third 

 and fourth subequal, the latter dilated apically; face fuscous j'ellowish, the mouth- 

 parts apically deep carmine. Mesonotum fuscous yellowish, the submedian Unes 

 sparsely haired, yellowish. Scutellum and postscutellum fuscous yellowish. Abdo- 

 men light fuscous, the incisures and pleurae fuscous yellowish, the distal segments 

 with a reddish tinge. Halteres yellowish basally, fuscous apically. Coxa; fuscous 

 yellowish, tarsi fuscous straw, the distal tarsal segments darker. Claws stout, 

 strongly curved, simple, the puhilli about half the length of the claws. 0\ipositor 

 yellowish, short, the terminal lobes with a length about four times the width, setose; 

 minor lobes short, broad, setose. 



Reared from bud galls, 3 mm. in diameter, on Spiraea salicifolia 

 collected by Miss Cora H. Clarke at Magnolia, Mass. Allied to 

 I. apocyni Felt. Type C. al759x. 



Itonida taxodii n. sp. Male. — Length 1.5 mm. Antenna; fuscous yellowish, the 

 fifth segment having the basal part of the stem with a length one half greater than 

 its diameter, the distal part with a length three times its diameter, the basal en- 

 largement subglobose, the subbasal whorl moderately thick, stout, the circumfUiim 

 stout, the loops moderately long; the distal enlargement cylindric, with a length 

 one half greater than its diameter, the whorl rather thick, the seta; stout and 

 longer on one face; the loops of the distal circumfidum slightly produced on one 

 face; terminal segment produced, the basal portion of the stem with a length 

 three times its diameter, the distal enlargement constricted near the basal fourth 

 and with a short, stout knob subapically. Palpi; first segment short, stout, the 

 second broadly oval, the third a little longer, more slender, the fourth more than 

 twice the length of the third. Mesonotum apparently fuscous, the submedian lines 

 yellowish. Scutellum and postscutellum presumably a pale yellowish. The 

 abdomen probably fuscous yellowish; genitaha presumably yellowish. Wings 

 hyaline, costa pale straw, subcosta uniting therewith before the basal half, the 

 third vein at the apex. Halteres yellowish. Legs apparently nearly a uniform 

 yellowish, the claws strongly curved, shghtly dilated subapically, the pulviUi dis- 

 tinctly shorter than the claws. Genitalia obscure in the preparation. 



Female. — Length 2 mm. Antennae hght browTi; fourteen segments, the fifth 

 with a short stem one fifth the length of the cylindric basal enlargement, which 

 latter has a length four times its diameter, is broadly constricted near the basal 

 third; subbasal whorl sparse, stout, subapical whorl scattering, stout; rather distinct 

 circumfili occur at the basal half and apically; terminal segment produced, with a
