glands about twice as long as wide, nearly one-sixth as long as 
total length of abdomen, apparently situated on each side of 
fifth abdominal segment. A smaller pair, immediately caudad 
to and adjoining larger pair, about three-fifths as long as latter, 
nearly three times as long as wide, subuniform in width 
throughout. 
LuZzON, Laguna, Los Bajios, at an altitude of about 50 meters, 
February 2, 1918, College of Agriculture accession No. 18178 
(Uichanco). On nether surface of fully expanded young leaves 
of Ficus nota Merrill (Moraceez).
