This meadow grasshopper is probably the most abundant mem- 

 ber of the family Tettigouiidre found in Indiana. It begins to 

 reach maturity in the central part of the State about July 10th, 

 and more frequently than any other of our species of Orcliclunu-m 

 is found in upland localities, along fence rows, and in clover and 

 timothy meadows. In early autumn it seems to be very fond of 

 resting on the leaves and stems of the iron weed, Ycrnonla fascicu- 

 lota Michx., so common in many blue-grass pastures. 



At times 0. ml (/a re appears to be somewhat carnivorous in 

 habit, as, on two occasions, I have discovered it feeding upon the 

 bodies of small moths which in some way it had managed to cap- 

 ture ; while on another date I surprised a female on the flowers of 

 a golden-rod, feasting upon a soldier beetle, Chauliognathus pcnn- 

 sylrunieus DeG. According to Hancock (1904) it is not only car- 

 nivorous but also a cannibal, as a female kept in captivity cap- 

 tured her mate and "holding his body between her fore legs ate the 

 larger portion of the soft parts, after first eating a hole in the 

 back." He suggests that the "long spines of the fore and middle 

 tibiae are occasionally used and connected in this species with its 

 carnivorous habits." 



0. mlgare is not only the most common member of the genus 

 locally but is more widely distributed than any other, its known 

 range extending from southern Maine and southern Quebec, north 

 and west through Ontario to northern Minnesota, Colorado and 

 eastern Wyoming, and south and southwest to North Carolina, 

 Macon, Ga. (Fox), northwestern Arkansas and northeastern 

 Texas. The larger, longer winged individuals have by many writ- 

 ers, including myself (1903, 385) been wrongfully recorded as 

 O. glaberrimum (Burin.), a species which R. & II. aver replaces 

 vulgare in the southern states and which I have included above as 

 0. erythrocephalum Davis.
