184 STUDIES IN AMERICAN TETTIGONIIDAE (oRTHOPTERa) 



11.4-14.7; Tinicum, Pennsylvania, 8.9-11.8; Castle Rock, Penn- 

 sylvania, 11.4-13.6; Cedar Springs, New Jersey, 9.3-10.8; Fay- 

 etteville. North Carolina, 9.7-10.8; Wilmington, North Carolina, 

 9.2-9.6; Florence, South Carolina, 10.6-11.9; Yemassee, South 

 Carohna, 9.3-9.6; Atlantic Beach, Florida, 9.4; Moline, Illinois, 

 11.4-13.7; West Point, Nebraska, 10.5-14.7 mm. The oviposi- 

 tor varies slightly from the normal perfectly straight type to one 

 in which an extremely weak upward curvature is appreciable, 

 suggesting the type found in spartinae, and one in which an open 

 sigmoid curvature is barely indicated, to the weakest appreciable 

 degree. The specimens from West Point, Nebraska, have the 

 ovipositor slightly heavier and averaging longer than in any 

 eastern series. Of the eastern material, that from drier upland 

 situations (Diamond Valley, Corn wells (back from the river), 

 Chestnut Hill, Castle Hock, Pennsylvania; Fayetteville, North 

 Carolina; Florence, South Carolina, and a number of other 

 localities) has the ovipositor frequently showing a suggestion of 

 an open-sigmoid curvature and averaging longer than in material 

 from marsh or swamp lands (Tinicum, Pennsylvania; Wilming- 

 ton, North Carolina; Yemassee, South Carolina; Atlantic Beach, 

 Florida, and other localities), and we believe the differences dis- 

 cussed above probably to be due wholly to environmental con- 

 ditions, ^^ particularly those governing oviposition, which in 

 situations of different character would indicate that different 

 plants are selected as the receptacles for the eggs. 



The present species is known from Eastport, Maine; Montreal, 

 Quebec, and Algonciuin Park, Ontario to Atlantic Beach, Flor- 

 ida,^^ and the Gulf coast as far as Beaumont, Texas. The 



'2 Different variations are found in occasional species, primarily due it would 

 seem to immediate environmental conditions and not sufficient to warrant 

 trinomial recognition. See under C. rngropleuroides in the present paper and 

 under C. cinereus and saltator in the next paper of the present series. Also 

 under Or chelimum concinnum, Trans. Am. Ent. Soc, xU, pp. 15 and 62, (1915), 

 and under Nemohius fasciatus fascinlus and its geographic race socius, Proc. 

 Acad. Nat. Sci. Phila., 1913, pp. 410 and 424, (1913). 



'^ Further south in Florida this species has not been found. Scudder's 1S77 

 record, with a query, of an immature individual from Fort Reed as his ensiferum, 

 ai)i)lies to ConocepJialus gradUimus; while the present authors' record from 

 Chokoloskee we now know to be based upon material incorrectly labelled and 

 probably taken in the vicinity of New York, New York.
