Gall. This species was reared from ash shoots, the young ter- 

 minal leaves forming a head and two petioles often coalescing to 

 produce a hoary, pubescent gall containing whitish larvae some 

 2 mm long. 



Larva. Length 2 mm, whitish, rather stout; head broad, obtuse 

 apically. Antennae rather stout, uniarticulate ; breast-bone bidentate, 

 subobsolete posteriorly. Skin nearly smooth, posterior extremity 

 broadly rounded, the latero-posterior angles with three or four 

 slender spines arising from more or less distinct tubercles. 



Female. Length 1.25 mm. Antennae one-half the length of the 

 body, sparsely haired, fuscous yellowish, yellowish basally; 16 

 sessile segments, the fifth with a length one-half greater than its 

 diameter, the terminal segment produced, narrowly oval. Palpi 

 scaled; the first segment short, subquadrate, the second broadly 

 oval, the third a little longer and more slender, the fourth nearly 

 twice the length of the third. Mesonotum pale yellowish, slightly 

 fuscous, the submedian lines indistinct. Scutellum, postscutellum 

 and abdomen pale yellowish, the latter slightly fuscous dorsally; 

 pleurae pale yellowish. Wings hyaline, costa brown. Halteres pale 

 yellowish. Coxae and femora basally yellowish, the distal part of 

 femora and tibiae fuscous yellowish, tarsi dark brown or black. 

 Ovipositor longer than the abdomen, the slender 'terminal lobes 

 with a length fully four times the width. Type Cecid. a 171 2.

This species was taken June 4, 1906 on sedge, Carex vul- 

 p i n o i d e a , at Albany, N. Y. 



Male. Length 1 mm. Antennae longer than the body, thickly 

 haired, light brown; 16 segments, the fifth with a stem one-quarter 

 longer than the basal enlargement; terminal segment irregularly 

 suboval, the apex obtusely rounded. Palpi ; the first segment short, 

 subquadrate, the second fully twice the length of the first, with a 

 distinct lateral knob, the third as long as the second, subrectangu- 

 lar, the fourth nearly twice the length of the third, slender, the 

 fifth one-quarter longer than the fourth, flattened, slender; face 

 light brown. Mesonotum dark brown with narrow, submedian 

 lines of fine setae. Scutellum reddish brown with sparse apical 

 setae, postscutellum yellowish. Abdomen yellowish brown, rather 

 sparsely clothed with yellowish hairs, tip of genitalia dark brown. 

 Wings hyaline, costa thickly clothed with blackish hairs; halteres 

 yellowish transparent basally, yellowish fuscous apically. Legs 

 nearly uniform light brown; tarsi slightly darker; claws rather 

 slender, uniformally curved. Genitalia; basal clasp segment 

 slender, internally with a broadly rounded lobe at the basal 

 third; terminal clasp segment with the basal third greatly 

 swollen; dorsal plate broad, deeply incised; ventral plate broad at
