SUMMER NUMBER 5 
and paler color will distinguish it from F. bispinosa which it resembles 
in general appearance. Like both F. cephalica and bispinosa the second 
segment of the antenna is extended upward and forward so that it overhangs 
the 3rd segment and bears two heavy spines on the dorsal surface near 
the anterior end. 
Described from numerous specimens taken from blossoms of Bidens sp., 
wild morning-glory, Carissa grandiflora, citrus, mango, avocado, papaya and 
beans at Miami March-June, 1919, by Mr. Mason, and a single specimen 
taken by the author from oak at Gainesville, April 20, 1919. 
Type in the author’s collection. Paratypes in the National Museum.
