sixteen antennal segments, though there is one additional. It is 

 easily separated by the distinctly shorter stem of the fifth antennal 

 segment and by genitalic characters. 



Male. — Length i mm. Antennae Y 2 longer than the body, rather thickly 

 haired, fuscous yellowish, the stems whitish 17 segments, the fifth with a stem 

 as long as the basal enlargement, which latter has a length J4 greater than its 

 diameter and bears a moderately thick whorl of long setae. Palpi : first seg- 

 ment with a length nearly three times its diameter, the second nearly twice as 

 long as the first, the third y 2 longer than the second, the fourth about as long 

 as the third. Mesonotum dark reddish brown. Scutellum yellowish white. 

 Postscutellum darker. Abdomen thickly haired, yellowish, genitalia fuscous 

 yellowish. Halteres whitish transparent. Coxae pale yellowish. Legs mostly 

 pale straw. Claws moderately long, curved, unidentate, the pulvilli nearly as 

 long as the claws. Genitalia: basal clasp segment moderately long, stout; ter- 

 minal clasp segment short, narrowly and irregularly oval ; dorsal plate long, 

 deeply and triangularly incised, the lobes broadly rounded ; ventral plate mod- 

 erately long, divided, tapering and narrowly rounded apically. Type Cecid.

Dicrodiplosis insolens new species. 



This peculiar species was taken by Mr. Howard Notman August 

 12, 1917, at Keene Valley. It is tentatively referred to this genus and 

 is remarkable among female Itonididinarise on account of the greatly 

 produced circumfili. 



Female. — Length 1.75 mm. Antennae about as long as the body, sparsely 

 haired, dark brown, with at least 13 and presumably 14 segments, the fifth with 

 a stem % of the length of the cylindrical basal enlargement, which latter has 

 a length about three times its diameter, is distinctly and broadly constricted 

 near the middle and has well developed, irregular circumfili basally and api- 

 cally, the loops with a length about equal to the diameter of the enlargement, 

 there even being a pronounced slackness or bowing of the longitudinal fili con- 

 necting the basal and distal circumfili, terminal segment wanting. Palpi : first 

 segment irregular, globose, the second with a length over twice its diameter, 

 the third fully l / 2 longer than the second and the fourth nearly twice the length 

 of the third. Mesonotum dark reddish brown. Scutellum and postscutellum 

 yellowish. Abdomen fuscous yellowish. Halteres yellowish transparent. Coxae 

 pale yellowish. Legs mostly dark brown, the anterior pair with the third, 

 fourth and fifth tibial segments mostly yellowish, the middle legs with the third 

 tibial segment yellowish and the posterior legs with the distal half of the second 

 tibial segment and the third and fourth segments whitish. Claws rather long, 

 moderately stout, strongly curved, unidentate, the pulvilli about l / 2 the length 

 of the claws. Ovipositor short, the terminal segment somewhat swollen and
