Enterprise, Sanford, Lake Istokpoga, Moore Haven, Sarasota 

 and Dunedin, Fla. ; Dec. 11 May 10 (TF. 8. B.) Eecorded by 

 other collectors from numerous localities between Appalachicola 

 and Jacksonville in the north, and Miami and Ft. Myers in the 

 south. At Dunedin, on March 22, 1913, it was found in abundance 

 on the foliage of the pickerel weed. Pouted eria cordata L., then in 

 full blossom along the margin of a pond. It has since been noted 

 in small numbers each season, but only in the adult stage, along 

 the pathways of low, open pine woods near the margins of wet 

 hammocks. Much more wary than Lcptysmfi, which it resembles 

 closely in form and habits, it often flies long distances when 

 flushed, and invariably alights on the leaves of cabbage palmetto 

 or green grass or sedge where, slipping quickly behind a leaf or 

 stem, it seeks to evade the pursuer. Sometimes, by approaching 

 quietly, it can then be grasped by a quick motion of the hand, 

 but is usually caught more readily with the net. Hebard has 

 noted its partiality for cat-tails, and it probably occurs among 

 green semi-aquatic vegetation throughout the mainland of Florida. 



The known range of K. rilrcipaniis is limited, extending only 

 from Lake Ellis, N. Car., south and west through southern Geor- 

 gia and Florida to Appalachicola in the latter State. The ma- 

 jority of the records of its occurrence have been made under the 

 names Arnilifi elilorizans and Rtcnacris clilorizans Walker, which 

 are synonyms, while the Carolina record of Arnilia cylindrodes 

 Stal (1873, 85) undoubtedly refers to a South American species. 



Tribe III. SCHISTOCERCI. 



To this tribe, as defined in the key, p. 304, belongs only the 

 single genus : 



I. SCHISTOCERCA Stal, 1873, f>4. (Gr., "cleft" + "tail.")
