Beak dark brown, extending to the mesocoxip, being 0.54 mm. 

 long. 



The pi'othorax is broad and short; thorax broad; wings 

 hyaline and covered with minute stipples ; veins slender and 

 brownish ; cubitus obsolete at the base. Stigma brown and 

 0.50 mm. long by 0.198 mm. wide. Total wing expansion, 

 6.94 mm. Legs black and hirsute, metathoracic legs long in 

 proportion to the others. 



The first three segments of the abdomen are ferruginous, as 

 are also the apical segments ; remainder of the abdomen black. 

 Honey-tubes reduced to a mere circular opening, and not very 

 conspicuous. Style obsolete. 



This form was taken in October on the ventral side of the 

 leaves of the dogwood. It is gregarious and was found in 

 great numbers. Later in the season it was found somewhat 

 sporadic on a great many other plants in the vicinity of ihe 

 dogwood, from which it seemed to have migrated.

This form was taken June 19, on the elm ( Ulmus anuricana /) . 

 It is gregarious in galls, which ray coworker describes as a new 

 species. Following is his description: "This gall occurs on 

 the dorsal side of the leaf of the elm {Ulmus antericana?) . The
