SUBFAMILY I. PHANEROPTERINjB.

are Tortugas Islands, Key West, Chokoloskee, Miami, Lake Worth, 

 Ft. Myers, Sanford and Gainesville. At Key West Hebard took a 

 female containing 124 fully developed and 14 partially developed 

 eggs from a bush of dahoon holly. Ilex cassine L., on March 16. 

 Davis captured a male at electric light in Ft. Myers on March 31, 

 and saw several others. At Miami Hebard found a young female 

 on March 5, and Davis a male and two nymphs on Sept. 22, all in 

 Brickell's Hammock. At Gainesville a male and female were 

 taken Sept. 20 Oct. 2, and at Stanford a female on Nov. 28. These 

 are the only published Florida records, and for so large an insect 

 they are very few. They indicate that the species must as yet be 

 very scarce in the State, and passes the winter in the adult stage. 

 Rehn (1917, 111) states that *Sf. couloniana is known only from 

 Cuba, the Isle of Pines and Florida. Saussure's type was from 

 Cuba, and it is said to occur over the whole Island.

This, the largest Tettigoniid known from the eastern United 

 States, was first recorded and described from this country by 

 Scudder (1862, 447) under the name of MirrocentriDn tJioracicum, 

 his specimen being a female from the Tortugas Islands. Scud- 

 der's name was placed by Erunner (1878, 359) as a synonym of 

 XtilpnocJilora inarglnclla (Serv.), and the species has been re- 

 corded as such a number of times from Florida and is listed under 

 that name by Scudder and Kirby in their catalogues. Rehn 

 (1917, 111) has separated our insect from A$f. marglncUa and placed 

 it under Saussure's Sf. cotrtouiana, a name considered by Bruuner, 

 Scudder and Kirby as a synonym of *Sf. inarginclla. Rehn gives his 

 reasons for his action thus: "The chief feature which distin- 

 guishes the species is the form of the stridulating field of the male 

 tegmina. This is least extensive, with its free margin almost 

 regularly arcuate and hardly angulate, and having a short strid- 

 ulating vein in inargincUa ; in couloniana the field is broader, with 

 a rounded obtuse angulation at the extremity of the vein, which 

 is somewhat heavier and longer." 



Two females in my collection from Mexico, one from Jalapa, 

 the other from Orizaba, differ from the Florida specimens only
