the Arnold arboretum, Jamaica Plain, Mass., October 31, Tomn 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-

the Cecidomyiid larva described by Osten Sacken under the name of 
Cecidomyia poeul wm.

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
