were collected at Puerto Barrios, Guatemala, March 20, 1913, 
and forwarded to us through the courtesy of Prof. E. Bethel of 
Denver, Col. The gall is an irregular, gouty stem swelling, composed 
of soft tissues with here and there irregularly oval cells with a diameter 
of approximately 2 mm. Entire swellings may have a length of 2 
to 9 cm.
