This moderate sized, reddish or dark brown species was ap- 

 parently reared at Albany, N. Y., April 11, 1908 from a rather 

 typical though slender R. strobiloides Walsh gall. It is 

 possible that this species came from an unrecognized twig gall. 

 Polygnotus species was also obtained. 



Female. Length 3 mm. /Vntennae extending to the second ab- 

 dominal segment, reddish brown; 16 sessile segments, the fifth 

 tapering distally, with a length fully twice its diameter; terminal 

 segment produced, evidently composed of two closely fused, sub- 

 acute. Palpi ; first segment short, stout, the second stout, with a 

 length three times its width, the third a little longer, more slender, 

 the fourth one-half longer than the third. Mesonotum dark brown, 

 the submedian lines indistinct. Scutellum and postscutellum reddish 

 brown. Abdomen dark browai. Wings hyaline, costa dark brown. 

 Halteres probably yellowish brown. Legs dark brown, the tarsi 

 almost black; claws stout, strongly curved, the pulvilli as long as 

 the claws. Ovipositor about one-half the length of the abdomen, 

 the terminal lobes with a length three times the width, narrowly 

 rounded. Type Cecid. aiSiia.
