The midges were reared from blueberries in June 19 14 and 191 5 

 by William C. Woods, Orono, Me. The species runs in the key to 

 near L. mitchellae from which it is easily separated by color- 

 ational characters and also by the presence of well-developed hooks 

 upon the ovipositor. A detailed description is given in the above 

 citation.

The fusiform stem galls of this species were rather common on 

 hedge bindweed (Convolvulus sepium) at Bath-on-t he- 

 Hudson, N. Y., in 1907. The gall was also taken by Mr L. H. Weld, 

 at Evanston, 111. The adults appear the middle of May. 



Gall. The monothalamous fusiform stem gall inhabited by 

 this species is some 1.5 cm in length and .5 cm in diameter. The 

 gall has a longitudinal central channel about two-thirds the length 

 of the swelling, the hypertrophied tissues being hard and corky. 



Larva. Length 3.25 mm, slender, pale orange. Head small, 

 antennae slender, tapering; breastbone slender, distinctly expanded 

 apically, bidentate, with a minute median tooth ; skin rather coarsely 

 shagreened; posterior extremity broadly rounded. 



Male. Length 2.25 mm. Antennae dark brown, fuscous- 

 yellowish basally; 17 segments, the fifth with a length slightly
