REPORT OF THE STATE ENTOMOLOGIST I912 I7I 



Male. Length 1.25 mm. 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- 

 an a, at Albany, N. Y., June i, 1906. 



Male. Length i mm. Antennae as long as the body, thickly 

 haired, dark brown; 15 segments, the fifth with a stem one-fourth 

 longer than the pyrif orm enlargement ; the terminal two segmejits 

 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. 

 Type Cecid. 107.
