upon the tall weeds and bushes along the borders of lakes and ponds, 

 and in sloughs and damp ravines." 



Blatchley (1. c, p. 452) made some incomplete observations on 

 the peculiar courting habits of this species, a subject which has been 

 elaborated by Hancock ('05). Hancock also describes the method 

 of oviposition. The female first gnaws the plant stem ; then bores a 

 hole and deposits an egg; and next, again gnaws the stem. The eggs 

 are laid in stems of blackberry, goldenrod, and horseweed (Leptilon). 



Houghton (Ent. News, Vol. 15, pp. 57-61. 1904) has published 

 interesting observations on the carnivorous habits of nymphs of 

 CB. niveus DeG. Cf. Parrott and Fulton, '14. 



Ashmead (Insect Life, Vol. 7, 241. 1894) reports that CH. nigri- 

 cornis (fasciatus) is preyed upon by the wasp Chlorion harrisi Fernald 

 (Isodontia philadelphica St. Farg. ). 



CBcanthus quadripunctatus Beut. Four-spotted White Cricket. 



This prairie species was found among the tall prairie grasses 

 blue-stem Andropogon and Panicum (Sta. I, g) Aug. 8 (No. 3); 

 and among the colony of cord grass, Spartina (Sta. I, a), Aug. 28 

 (No. 179). 



Blatchley ('03, p. 453) reports it on "shrubbery and weeds in 

 fence-rows and gardens; and along roadsides." This indicates how 

 a prairie species adjusts itself to the conditions produced by man. 

 Parrott (Journ. Econom. Ent., Vol. 4, pp. 216-218. 191 1) gives 

 figures of the eggs of this species and describes its method of ovipo- 

 sition in raspberry stems.

Cicada dorsata Say. Prairie Cicada. 



Although this species was not taken at Charleston, a single speci- 

 men (No. 185) was captured at Vera, Fayette county, 111., Septem- 

 ber 1, on a giant stool of blue-stem Andropogon. Osborn (Proc. 

 Iowa Acad. Sci., Vol. 3, p. 194. 1896) reported one specimen from 

 Iowa; Woodworth, (Psyche, Vol. 5, p. 68. 1888) says: "On the 

 prairies, Illinois to Texas"; and MacGillivray (Can. Ent., Vol. 33, p. 

 81. 1901) adds Missouri, Colorado, and New Mexico.

 Campylenchia cnrvata Fabr. 



This bug was taken in sweepings made in the colony of cone- 

 flower, Lcpachys pinnata (Sta. !,<?), Aug. 12 (No. 40).
