SUBFAMILY IV. COXOCEPHALIXJE. 571 



(,'. brcripcniiiv and has been placed by R. & H. as a synonym of 

 that species. 



This larger form differs from other meadow grasshoppers in 

 the manner of ovipositiou, as, instead of always depositing its 

 eggs in the stems of grasses, it sometimes seeks the turnip-shaped 

 gall so common on certain species of Salu' (willow), and oviposits 

 between their scales. The gall is not formed by the grasshopper, 

 but by a dipterous insect belonging to the family Cecitlontyidce. 

 Although I have never seen the eggs deposited I have on a num- 

 ber of occasions found them within the galls, but did not know to 

 what insect they belonged until Wheeler (1890) published his ex- 

 cellent account of the oviposition of this species as noted in Wis- 

 consin. From that I quote as follows: 



"On September 8th I observed a female in the act of oviposition. She 

 was perched with her head turned toward the apex of the gall. Slowly 

 and sedately she thrust her sword-like ovipositor down between the leaves, 

 and, after depositing an egg, as slowly withdrew the organ in order to 

 recommence the same operation, after taking a few steps to one side of 

 where she had been at work. She soon observed me and slipped away 

 without completing her task. The number of eggs found in a gall varies 

 considerably. Sometimes but two or three will be found, more frequently 

 from 50 to 100. In one small gall I counted 170. The egg is cream-colored, 

 very thin, elongate oval in outline, and measures 4x1 mm." 7 " 



In Indiana the young of C. breuipennis emerge about the mid- 

 dle of May and reach maturity about August 10. One which was 

 still in the nymph stage on October 21st, was found to have a 

 white hairworm, (iord'nis sp? eight and a half inches long in its 

 abdomen. The development of the nymph had probably been re- 

 tarded by the presence of the parasite. Long-winged forms of 

 this species are occasionally met with, but I have taken only one, 

 and R. & H. state that only 3.2 per cent of the 555 specimens ex- 

 amined by them were macropterous. Two macropterous females 

 sent in by Ilubbell from Jackson Co., Mich., vary but slightly in 

 size, yet the ovipositors measure respectively 0.3 and 12 mm. in 

 length. 



The known range of C. brcuipennis is a wide one, extending 

 from Maine and Montreal north and west to Algonquin Park, On- 

 tario, northern Minnesota and Nebraska, and south and south- 

 west to northern Florida and Dallas, Texas. Fn Florida it ap- 

 pears to be very scarce, being known definitely only from Atlantic 

 Beach, South Jacksonville and Gainesville.

 otis occasions, of the eggs of an Orchelimum in the turnip-shaped galls of Sali.r cordata. 

 Their shape and proportional dimensions, as given liy him, differ much from those of 

 C. brct'l^ciin-is, as they were cylindrical, .16 to .17 of an inch long, and seven times 

 as long as wide (W. S. B.).
