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 oft 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 sieie 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 Hexatonue 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 olci 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.
