This gall is a large, thick, knotty, irregular, rather ovate swelling 

 wiiieh may be so small as to be scarcely noticeable or which may attain 

 a length of two or three inches and a diameter of one inch. It is usually 

 near the summit of the stalk and covered with the short flower stems of 

 the panicle. The larvae are numerous, each enclosed in a thin transparent 

 chamber and imbedded in the soft pithy tissue which fills the gall. It 

 occurs on Lactuca canadcnse and possibly on other species. It was first 

 described by Bassett who does not state the source of his material. It has 

 since been reported from New York and the author has collected it in 

 Ohio and Delaware. It no doubt lias a very wide range and always oc- 

 curs on Lactuca.

A more or less irregular, usually reniform gall varying from i/o to 

 1 inch in length, occasionally longer and may be as much as i/^-iuch in 

 diameter. Green and rather pithy in summer, becoming brown, hard and 

 rather woody in winter. Contains a large number of larval chambers. 

 It occurs on the stems and is restricted to one side, causing the twig to 

 be so curved as to occupy the concave surface of the gall. This gall was 

 first described by Ashmead from collections on Florida material of Vac- 

 ciniurn conjmbosiim. He also states that he received what appeared to be 

 the same gall on V. pcnnsi/lvanicum from Mr. Wm. Brodie, of Toronto, 

 Canada. It has also been rejtorted from New York by Beutenmiiller. The 

 writer has collected it in Delaware on 1'. coriimhoKuni. and another unde- 

 termined species of Vuvcinium. Collected in Indiana on V. corymhosum.
