humid lowland forest tract. Hancock ('ii, pp. 297, 392-394) has 

 discussed the habitat of this species. 



Chlocaltis consl^crsa Harr. Sprinkled Grasshopper. (PI. TA'II, fii^. 6.) 

 This locust was taken from the ground, mainly among leaves, in 

 the upland forest (Sta. IV, a) Aug. 16 (No. 67); in sunny open 

 places Aug. 17 (No. 93) ; and along a path through the forest among 

 dry leaves Aug. 22 (No. 122). 



Morse ('04, p. 19) considers this a forest, forest-margin, and 

 thicket species, and Hart ('06, p. 75) says it frequents "open woods 

 on ground encumbered with leaves, branches, and bushes." Consult 

 Scudder (Final Report upon the Geology of New Hampshire, \^ol. 

 I. pp. 371—372. 1874) for an account of the egg-laying habits of 

 this species; also Hancock ('11, pp. 347-351) for its habits. 



Spharagcuion bolli Scudd. Boll's Grasshopper. (PI. LVH, fig. 4.) 



A male of this species w'as taken on the ground on leaves in the 

 upland forest (Sta. IV, a) Aug. 16 (No. 67); a dead female was 

 found clinging to the tip of a plant stem on the most open part of 

 the slope (Sta. IV, &) from the upland forest to the lowland Aug. 

 22 (No. 133) ; and a female was taken among leaves on the ground 

 in the upland forest (Sta. IV, a) Aug. 23 (No. 150). T. L. Hankin- 

 son found an adult and a nymph in the Bates woods June 28, 191 1 

 ( No. 7678 ) . ( C f . Hancock, ' 1 1 , pp. 362-364. ) 



The positive heliotropism or negative geotropic resjionse shown 

 in diseased grasshoppers is of interest. It may be caused either by a 

 fungous or bacterial disease. (Cf. Gillette, Bull. No. 6, n. s., Div. Ent. 

 U. S. Dept. Agr., pp. 89-93. 1896.) 



Morse ('04, p. 15) considers this an exceptional ground-inhabiting 

 or geophilous species since it is "an inhabitant of xerophytic forests as 

 well as of open fields, and in the Southern States is found cjuite as 

 often in the forest as on the open plain." 



Mclanoplus diffcrcutialis Thomas. Differential Grasshopper. 

 Consult the list of prairie invertebrates, p. 167. 



Mclanoplus atlanis Riley. Lesser Grasshopper. (PI. LVII, fig. 8.) 

 A single specimen was taken on the ground in the upland forest 



(Sta. IV, a) Aug. 16 (No. 67). The open character of parts of this 



dry forest affords favorable conditions for this species. 



Morse ('04, pp. 19, 42) considers this a characteristic species 



of open countrv, but "likelv to be found anywhere." Hancock ('11. 



pp. 415-416) has described the habitat of this species.
