the Arnold arboretum, Jamaica Plain, Mass., October 31, 19 11 and 

 provisionally identified as Neuroterus umbilicatus 

 Bass. These galls produced numerous specimens of a Neuroterus, 

 though they are considerably larger than the galls generally recog- 

 nized as those of this species. It is possible that this male represents 

 the Cecidomyiid larva described by Osten Sacken under the name of 

 Cecidomyia poculum. 



Male. Length 1 . 5 mm. Antennae one-fourth longer than the body, 

 thickly haired, fuscous yellowish; 14 segments, the fifth with stems 

 two and one-half and three and one-half times their diameters 

 respectively; terminal segment produced, the basal portion of the 

 stem with a length fully five times its diameter, the distal enlargement 

 cylindric, with a length about two and one-half times its diameter 

 and apically with a long, fingerlike process. Palpi; first segment 

 irregularly subquadrate, somewhat swollen distally, second segment 

 one-half longer than the first, narrowly elliptical, the third segment 

 a little longer and more slender than the second, the fourth about 

 one-fourth longer than the third, dilated apically. Mesonotum 

 reddish brown, the submedian lines sparsely haired. Scutellum 

 fuscous orange, post scutellum yellowish. Abdomen sparsely haired, 

 fuscous yellowish, the pleurae darker. Genitalia fuscous yellowish. 

 Wings hyaline, costa light straw, the third vein uniting with the 

 margin well beyond the apex of the wing. Halteres whitish basally, 

 fuscous apically, the legs mostly a nearly uniform fuscous straw; 

 claws long, strongly curved, the pulvilli about one-half the length 

 of the claws. Genitalia; basal clasp segment long, moderately stout; 

 terminal clasp segment long; dorsal plate long, triangularly incised, the 

 lobes obliquely truncate; ventral plate long, broad, tapering, deeply 

 and roundly emarginate, the lobes stout. Type Cecid. a2oo7a.
