The galls oi parvus Roh., insularis Kincaid, tiigei- Prov., albirictus 

 Cress., orbita/is var. nigei- Nort., perditiis Roh., and waiirus Roh., are 

 not known. I have not seen nor have I a description of the gall of 

 salicicola E. A. Sm. It occurs on Salix alba.

Female. — Length 5 mm. ; length of anterior wing 5 mm. Head seen from the 

 side narrowed toward occiput. Clypeus deeply, circularly emarginate ; lobes long 

 and rather sharp. Middle fovea subquadrate, distinct, walls somewhat sloping. 

 Antennal fovese distinct above the antennae. Frontal crest prominent, unbroken. 

 Ocellar basin not well defined, but the walls are sharp on the lower margin and about 

 anterior ocellus. Interocellar furrow very faint; lateral ocellar furrows rather broad 

 and shallow, hardly reaching the antennal foveoe. The head around the ocelli is rather 

 closely, finely punctured. F"ourth antennal joint a very little shorter than the third ; 

 apical joint equal in length with the preceding one. Claws deeply cleft, inner tooth 

 shorter. Venation normal ; stigma rounded on the lower margin, obliquely subtrun- 

 cated at apex. Sheath broad at base, obtusely rounded at apex, the upper margin is 

 not straight. Cerci slightly longer than the sheath above. Black : head except a 

 large spot enclosing ocelli, pronotum, tegulas, abdomen beneath and apical segments 

 above, legs entirely except the bases of the coxte sometimes, cerci ferruginous. The 

 color on the legs and tegulae is sometimes somewhat pallid. Apical joints of the 

 antennse brownish. Wings clear hyaline, iridescent ; venation pale brown, basal part 

 of costa and stigma subpallid. 



Male. — I have not seen the male but it is colored like the 9- 



Habitat.— Coww., Ill, N. Y. (Norton); Canada (Prov.); Colo- 

 rado (Ashm.). 



The gall consists of a lateral enlargment of the twig and varies 

 from 4-9 mm. in length, and 3-4 mm. in width. It is monothalamous. 



Walsh's species gemma has the flagellum red beneath in the c?, but 

 otherwise agrees in color with orbitalis. A comparison of the types of
