emerges next spring. A gall similar to that of fruiticola was 

 found by Mr. L. H. Weld, at Evanston, 111., in the acorn of the 

 swamp oak {Q. platanoides) which, when the adult is known, 

 will undoubtedly prove to be a new species. 



Habitat: N. Y., Conn., N. J., Penn., 111., Mich., Mo.

Forms a flattened tooth-like or wedge shaped gall on the 

 outside between the cup and the acorn with the ends more or 

 less protruding. It lies in a depression and is of a light brown 

 color. Often there are as many as eight galls on a single 

 acorn. It occurs on red, scarlet, black and scrub oak. Ac- 

 cording to H. F. Bassett the galls mature in autumn, and early 

 in the spring following part becomes imagos, another part re- 

 maining in the larval state another year, while a few remain in 

 this condition still longer, and, as suggested by C. V. Riley, 

 may develop the third year. 



Habitat: Ottawa, Can., Conn., N. Y., N. J., Penn., and westward.

Female. — Form robust. Uniform light cinnamon brown. 

 Legs somewhat paler with the middle and hind femora dark 

 brown. Head finely granulated and subtriangular in shape. 

 Antennae 14- jointed, stout and almost uniform in width, 1st. 

 joint long, 2nd. small, 3rd. long, 4th., 5th., and 6th. shorter 

 than the 3rd. and subequal. The following joints small and 

 almost equal in size. Thorax robust, about as long as broad, 

 finely and evenly granulated. Parapsidal grooves well defined, 

 punctate, inwardly curved anteriorly, thence parallel to nearly 

 the scutellum where they curve outwardly and converge, 

 though fairly well apart. Anterior parallel grooves fine and 

 extending a little beyond the middle of the thorax where they 

 are slightly divergent. Lateral grooves short. Collar rugose. 

 Pleurae minutely aciculated. Scutellum more granulated than 

 the thorax with a broad prominent transverse shining groove
