males and toward 5 p. m. they commenced egg-laying on the sides 
of the containing vessel, large shell vials. By 7 p. m. the sides of the 
vials were black in places with the large, dark-colored eggs. This 
data would seem to place the time for oviposition at about sunset. 
The females are very good fliers and often travel for long distances 
before alighting as is shown toward sunset when they fly for long 
stretches up-stream. The males are rather poor fliers, due in part, 
possibly, to the weight of the long antennae and, as stated before, 
this sex prefers to skulk rather than fly. When the males fly, they 
do so heavily and seize the first support that they collide with and 
hang on, occasionally flying on immediately to another support. 
When the male comes in contact with a stem, he very often ascends 
to the top by means of a part-flying, part-climbing motion and, on 
reaching the summit, flies off to another place. As a rule the flies, 
especially the females, alight on a single grassblade, but very often 
the males are observed on two blades, the legs of one side on one 
blade and those of the opposite side on the other; when the body 
thus hangs between the stalks, the tarsi diverge from one another, 
whereas on a single support, the legs converge. 
Hexatoma was preyed upon by large numbers of a Scatophagid 
fly that occurred in great abundance in this vicinity and seemed to 
be subsisting almost entirely on these flies. At least twenty of these 
predaceous flies were noted with Hexatoma and this species seemed 
to constitute the principle insect enemy of the crane-fly. They would 
lurk on the grass-blades and sally forth after their prey, carrying it 
back to some point to feed upon it. It is probable that the blood is 
taken since the body of the Hexatoma appeared almost uninjured 
when examined. On an old beam where males had a habit of walk- 
ing up the vertical face, a small spider's web was found, in which 
11 specimens were entangled, 2 being still alive; 8 of these were 
males, the remaining 3, females. 
The males especially can walk up smooth surfaces, as glass, mov- 
ing the legs alternately and awkwardly. The first pair taken were 
in copulation but in placing them in the vial they became disengaged 
and ran about in the container. After a short time they began to 
copulate in the tube.
