A monothalamous stem-gall, scarred with brown furrows on the outside. 

 The larval cavity fills the inside, and sometimes reaches into the stem-pith 

 above and below. Not as common as the two larger stem-galls of the 

 golden-rod. On goldenrods, Solidago.

This is an irregular, rounded or kidney-shaped gall at the base of the 

 stem. Sometimes at one side of the stem, sometimes encircling it. 

 Leathery outside, pithy within. Many celled, with orange-colored larvae. 

 About 10 by 15 mm., although varying considerably in size. When young 

 green, becoming brown. On goldenrod, Solidago rvgosa. 



Solidago juncea.

 Thompson. Psyche, 1907, v. 14, p. 71-72, fig. 1. 

 An ovate, monotbalamous gall growing on the underground stem. It 

 is evidently a deformed bud. About 3 cm. long, 1 cm. wide. Overlapping 

 scales show some green. Walls fleshy, rather thick. The insect emerges 

 from the tip in May or June. Galls found in the fall. Common. On 

 goldenrod, Solidago jmtcea.

Rhopalomyia hirtipes Pelt, 23d rept. ins. N. V. t. L907, 1908, p. 358, 363, pi. 34, lit;-. 6. 



An irregularly oval, fleshy gall, attached to stems underground. Light 

 brown with rough, darker spots. 1-2 cm. in either diameter. Shrivelled 

 quickly. Very abundant on goldenrod, Solidago juncea. July. The in- 

 sects reared from these galls agree so closely with Rhopalomyia hirtipes 

 O. S. as to seem identical, but the typical gall of that species is so dissim- 

 ilar as to make their identity doubtful. 



Solidago canadensis.
