The fuscous yellowish species described below was taken at 

 Albany, N. Y., May 9, 1910 on wild geranium, Geranium

 with a length about one-third greater than its diameter; distal 

 s gment produced, with a length over twice its diameter, narrowly 

 rounded apically. Palpi; first segment irregularly ovoid, the second 

 narrowly oval, with a length about twice its width, the third one-
