 have as vet been pointed out. 



About Dunedin, Fla., nymphs of 8. o. floridanii are frequent 

 from February 1 to April 15, but the adults have been taken only 

 in October. It occurs in the tall grasses about the margins of 

 brackish marshes and on weeds in low wet places in pine woods. 

 During the summer and autumn months this appears to be a com- 

 mon katydid throughout Florida, having been recorded from nu- 

 merous localities by other collectors. At Homestead it was found 

 by R. & H. (1914c, 399) "on the prairie-like everglades, where they 

 were scarce in the day time, but plentiful at night, perched on the 

 grasses, stridulating fearlessly. Their note is an indescribable 

 buzz and click." 



The range of this southern form is given by R. & H. (I914b, 

 322) as '"extending from Big Pine Key and Detroit, south Florida, 

 as far north typically as Jacksonville, Fernandina and Atlantic 

 Beach, westward as far as eastern Texas, intergrading in the At- 

 lantic Coast region, at least, into the northern subspecies (cari- 

 ntitu) over an extensive area covering from southern Georgia to 

 eastern South Carolina."

"Differing from floridana floriclana in the lateral margins of the 

 pronotal disk being more angulate and carinate almost or quite continu- 

 ously; in the stridulating field of the male tegmina being proportionally 

 broader, in the sutural margin of the tegmina distad of the anal field 

 being more arcuate and in having a longer and heavier ovipositor.

 It will be noted that the width of the stridulating field of tegmina 

 is said by R. & H. to be broader than in florhJuini. whereas the 

 leading character given in their key to separate florifhnta from 

 typical ablcinc/i folia is the narrower stridulating field of the for- 

 mer. The measurements are also in great part intermediate be- 

 tween typical oli1oncjif alia and floriilana. They record numerous 

 intergrading forms between floridana and carinata, but T regard 

 the latter as only an intermediate form, connecting oblongifoliQ 

 and its southern race, floritlana and therefore scarcely worthy of 

 a special name. As noted above the extremes are sufficiently dis- 



G5 This form should probably bear the varietal name saiissurci Bruner, as he first men- 

 tioned it (1886, 196) as follows: "A sixth species (of Amblycorypha) occurs along the 

 Atlantic coast from Maryland southward. It is nearly of the same size as oblongifolia but 

 differs from it in having the dorsum of pronotum very smooth and also in several other 

 important features. It might therefore be called A. sanssurci after M. Henri de Saussure." 

 As R. & H. claim that this description, as such, is unrecognizable, I have retained their 

 name.
