REPORT OF THE STATE ENTOMOLOGIST IQI2 I7I 
Male. Length1.25mm. Antennae longer than the body, sparsely 
haired, dark brown; 14 segments, the fifth with a stem one-fourth 
longer than the subcylindric enlargement ; terminal segment reduced, 
tapering to an acute apex. Palpi; the first segment short, stout, 
narrowly oval, with a large, irregularly oval sensory pit near the 
basal internal angle, second segment a little longer, more slender, 
the third longer and more slender than the second. The entire body 
a nearly uniform very dark brown. Wings hyaline, costa light 
brown, subcosta uniting with the anterior margin near the basal 
half. Halteres yellowish basally, light fuscous apically. Legs a 
light yellowish brown, the distal tarsal segments somewhat darker ; 
claws long, slender, strongly curved, slightly denticulate, the pul- 
villi a little shorter than the claws. Genitalia; basal clasp segment 
short, stout, obliquely truncate; terminal clasp segment thickly 
haired, long, stout, slightly expanded and broadly rounded; dorsal 
plate short, stout, triangularly emarginate, lobes somewhat separated 
and broadly rounded, other organs apparently fused into an irregu- 
larly subquadrate process having conspicuous prolongations distally 
at the median and lateral angles. Type Cecid. 1258.

This species was taken on ironwood, Carpinus carolini- 
pata, at Albany, N. Y:, June 1, 1900. 
Male. Length 1 mm. Antennae as long as the body, thickly 
haired, dark brown; 15 segments, the fifth with a stem one-fourth 
longer than the pyriform enlargement; the terminal two segments 
much reduced, narrowly fused, the fifteenth ovoid. Palpi; the first 
segment suborbicular, broad, the second twice the length of the 
first, elliptical oval, the third more slender, a little longer. Mesono- 
tum black with submedian lines of fine hairs. Scutellum dark brown 
with sparse apical setae. Abdomen dark brown. Wings hyaline, 
costa and subcosta reddish brown, the latter uniting with the an- 
terior margin at the basal half; halteres yellowish transparent. 
Legs pale grayish, tarsi variably tinged with reddish; claws stout, 
strongly curved, simple. Genitalia; basal clasp segment long, 
relatively slender, obliquely truncate; terminal clasp segment stout, 
short, with a long, apical tooth. Dorsal and ventral plates not easily 
distinguished. There appear to be a pair of suboval appendages 
within, much resembling the terminal clasp segment, though these 
structures may be a convolute portion of the very broad dorsal 
plate; if so, the ventral plate is a narrow, subtriangular process 
narrowly rounded distally; style slender, projecting anteriorly.
