OSTHOPTEKA OF INDIANA. 377 



of the ovipositor in the female. Ovipositor straight, quite broad and 

 heavy. Male cerci of medium length, rather stout, tapering gently 

 toward the apex, and with a strong sub-basal tooth. 



Measurements: Male — Length of body, 14 mm.; of tegmina, 9 

 mm.; of hind femora, 13.5; of pronotum, 3.5. Female — Length of 

 body, 15 mm.; of tegmina, short- winged form, 8.5 mm.; of tegmina, 

 long- winged form, 17 mm.; of hind femora, 14 mm.; of ovipositor, 

 16 mm. 



In Indiana this handsome insect has been taken in G-ibson, Vigo, 

 Fulton, Marshall, Starke, Lake, Kosciusko, Wells and Steuben coun- 

 ties, and probably occurs in suitable localities throughout the State. 

 It appears to be a semi-aquatic species, inhalnting only the margins 

 of ditches, large ponds and lakes, where it abides in the tall, rank 

 grasses and sedges growing in the shade. It reaches the perfect 

 stage about July 1st in southern Indiana, and in Fulton Coimty has 

 been taken as late as October 24th. The males leap actively when 

 approached. The females are more clumsy and usually dive head- 

 long into a l)unch of fallen grass. They can then be most readily 

 ■captured by clasping the hand about a bunch of grass stems or 

 "branches of shrubs, on the under side of which the insects have 

 laken refuge. 



NigropUura has been recorded only from Iowa, Nebraska and 

 Ithaca, New York, specimens having been sent me from the latter 

 locality by one of my correspondents, thus extending eastward its 

 Icnown habitat by more than 700 miles. 



Of its habits in Nebraska, Bruner (loc. cit.), has written as follows: 

 "It is quite plentiful among the rank vegetation on low moist ground, 

 and is especially common in wet places where the "cut grass" 

 {Leersia oryzoides Swartz) grows. The supposition is that this grass 

 offers a better place than usual for the deposition of its eggs, which 

 are deposited between the leaves and stems of grass. Grapevines 

 and other creeping plants which form- matted clusters that afford 

 ■shelter from the noonday sun and the bright light of day are 

 favorite haunts of this and other species of our nocturnal grass- 

 hoppers and a few of the arboreal crickets."
