apically, the tarsi black. Ovipositor as long as the abdomen, the 

 terminal lobes long, slender, subacute and with three or four stout 

 hooks. Type Cecid. ai576. 



Lasioptera murtfeldtiana Felt 

 1909 Felt, E. P. Econ. Ent. Jour., 2:288 



Several specimens of this form were reared September 9, 1896 

 from seeds of sunflower taken at Kirkwood, Mo. Apparently the 

 same or a closely allied insect was obtained from wild sunflower seeds 

 August 25, 1884 from Ottawa, Kan. We are indebted to the courtesy 

 of the National Museum for an opportunity of describing this species. 



The sunflower seed infested by this insect appears to be normal, 

 the adult escaping from the pupa after the latter was nearly free 

 from the base of the seed. 



Exuviae. Length 2.5 mm, semitransparent, except for the light 

 brown dorsum of the abdominal segments; antennal sheaths short, 

 with a short, obtuse, triangular process basally; dorsal horns short, 

 rather stout. Wing pads extending to the third abdominal segment, 

 leg cases to the fifth or sixth abdominal segment; dorsum of the 

 abdominal segments thickly clothed with short, stout, chitinous 

 spines; these evidently give the dark brown color mentioned above. 



Male. Length 2 mm. Antennae short, dark brown, 17 segments; 

 the fifth with a length about three-fourths its diameter, the terminal 

 segment slightly produced, broadly rounded apically. Palpi; first 

 segment rather long, rectangular, the second a little stouter and 

 as long as the first, the third one-half longer and more slender than 

 the second, the fourth nearly twice the length of the third, more 

 slender. Mesonotum dark brown, the submedian lines thickly 

 haired. Scutellum dark brown, yellowish brown apically. Post- 

 scutellum darker. Abdomen apparently a nearly uniform yellowish 

 brown, the genitalia fuscous. Wings hyaline, costa mostly dark 

 brown, the white discal spot apparently missing, the third vein 

 uniting with costa at the distal third. Halteres reddish brown. 

 Legs a nearly uniform dark brown, the femora and tibiae apically 

 narrowly ringed with pale yellowish. Genitalia; basal clasp segment 

 long, stout; terminal clasp segment, short, stout, swollen basally; 

 dorsal plate short, broad, deeply and triangularly emarginate; 

 ventral plate long, tapering, broadly rounded. Harpes long, with 

 a narrow, chitinous process apically. Type Cecid. 902. 



Lasioptera center ensis n. sp. 



This name is proposed for a yellowish orange larva inhabiting a 

 double celled gall at the base of the stem of Impatiens 

 a u r e a and taken at Karner, N. Y., September 6, 1906. 



Gall. The gall is soft, green, one-half of an inch long, one-third of 

 an inch in diameter, and is composed of two cells.
