72 THE FLORIDA BUGGIST 
the abdomen; decidedly constricted in the middle. Hairs of the fringe long 
and nearly equal in length; seven of a second row present. 
Abdomen swollen posteriorally. Rather long spines on the posterior por- 
tion, not knobbed. Tube tapering markedly, its length exceeded by six 
of the longer terminal spines. 
Described from a single female. 
Collected from Hop Hornbeam (Ostrya virginiana) by beating, Mar. 
1917, by H. L. Dozier. 
Type in the author’s collection. 
In the author’s key (Entomological News, XXVII, p. 129) this species 
goes to A. Flavipes Jones, but it differs markedly in its size, relative 
length of antennal segments, and the color of the antennae and tarsi.
