length of the ovipositor, and so more often endeavor to escape by 

 burrowing beneath the dense masses of fallen grass and reed 

 stems which are always found in their accustomed haunts. 



The long winged form was first taken in some extensive low 

 ground meadows in Kosciusko County. Here the long and short 

 winged forms were about equally abundant. The former flew 

 readily when approached, but to no great distance. A few of 

 the long winged ones were also taken near Bass Lake, Starke 

 County. The specimens from these northern counties are more 

 siender bodied than those from the south, where only the short 

 winged form has been found. 



Scudder's types were from Illinois and the known range of 

 the species extends from eastern Pennsylvania and southwestern 

 Ontario west to Minnesota, eastern Nebraska and Kansas, while 

 Knox County, Ind., is the most southern station recorded east of 

 the Mississippi. Walker states (1904, 341) that in southern On- 

 tario it is plentiful but limited in distribution. "It frequents 

 open marshy borders of creeks and ponds, where it leaps about 

 with wonderful agility among the tall grasses and sedges." 



R. & H. (1915b, 209) state that at Cornwells, Pa., they found 

 dttcnuatiis "very scarce in high grasses and plants along the 

 shore of the Delaware River, and in moderate numbers in a small 

 marshy area adjoining. The males were usually found in the 

 grass or perched on nearby plant leaves, whence they sprang 

 away with alacrity. The females were never as conspicuous and 

 sprang away with great swift leaps, then, hiding on the opposite 

 sides of grass stems and leaves in the deepest tangles of vegeta- 

 tion, they proved very difficult to locate. Over its wide distribu- 

 tion it is doubtless restricted to damp spots and marsh areas." 



My Xipliid'utm scudderi (1892b, 20) was based on the short- 

 winged form of C. attenuatus while the A', lanccolatuin mention- 

 ed by Bruner (1891, 59) also refers to attenuatus. I find that the 

 length of the ovipositor among the different species of Conocepha- 

 lux is not at all dependent upon the age of the insect. In attcnua- 

 1 us it is almost as long after the third, and fully as long after the 

 fourth moult as it is in the adult; while a female of st rictus has 

 been taken, with no vestige of tegmina, in which the ovipositor 

 measured 18 mm. The eggs of attenuatus, as the length of the 

 ovipositor indicates, are laid between the stems and leaves of the 

 t;;ll rank grasses among which the insect lives.
