Lasioptera virginica Felt 

 1909 Felt, E. P. Econ. Ent. Jour., 2:287 



This species was reared February 9, 1909 from a stem gall on marsh 

 St. Johnswort, Hypericum virginicum. 



Gall. Length 1 cm, diameter 8 cm, subglobose, monothalamous. 

 The large, irregular central chamber is surrounded by rather thick 

 walls, the outer part soft, the inner irregularly hardened and black- 

 ened. Taken by Cora H. Clarke at Magnolia, Mass., October 10, 

 1908. Numerous parasites were reared April 18, 191 2. 



Female. Length 2 mm. Antennae dark brown, 18 or 19 seg- 

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

 terminal segment slightly produced, narrowly oval. Palpi; the 

 first segment presumably short, subquadrate, the second probably 

 narrowly oval, the third slender, with a length about four times its 

 diameter, the terminal segment one-fourth longer than the preced- 

 ing. Mesonotum dark brown, margined laterally and anteriorly 

 with silvery scales, the submedian lines sparsely haired. Scutellum 

 reddish brown with a few white setae apically, postscutellum a little 

 darker. Abdomen black, the segments with narrow submedian 

 spots posteriorly, those of the first slightly confluent; ovipositor 

 yellowish; venter suffused with silvery scales. Wings hyaline, costa 

 black, the third vein uniting with costa a little before the basal half. 

 Halteres yellowish whitish, slightly fuscous basally. Coxae and 

 femora basally fuscous yellowish, the distal portion of femora, tibiae 

 and tarsi black, the articulations narrowly annulate with white, the 

 posterior tarsi broadly banded basally; claws stout, evenly curved, 

 pul villi as long as the claws. Ovipositor about two-thirds the length 

 of the abdomen, the terminal lobes long, narrowly oval. Type 

 Cecid. ai9i5.
