14 ENTOMOLOGICAL XEWS. [Jan., 'l6 



Spring Orthoptera found on the Islands in the Vicinity 



of Charlotte Harbor, Florida. 



By Morgan Hebard, Philadelphia, Pa. 



In May, 191 5, the author was able to investigate a number 

 of localities in this region^. The work covered only a brief 

 period, but in that time the various environmental conditions 

 of these islands were, in several cases, thoroughly investi- 

 gated. The material, 216 specimens, representing forty-five 

 species, is in the collection of the author. 



Hammock. 

 Scarcely any "hammock" jungle condition was to be found 

 on these islands. One small area, however, on the north end 

 of Captiva Island was examined, where, in the heavy scrub, 

 occasional gumbo limbo (Bursera simarnha) and other of the 

 typical trees of this environment were found. Scarcely any 

 Orthoptera were obtainable, probably due mainly to the dilute 

 condition of this element, the surrounding groves of cabbage 

 palmetto (Sabal palmetto) proving almost wholly unproduc- 

 tive and nearby extensive sandy stretches of short grass 

 revealing only- a few of the more ubiquitous forms. On one 

 tree (Exothea paniadata), scarce in this hammock growth, a 

 single specimen of OUgacanthopus prograptus was found, while 

 from nearby bushes a specimen of Cryptoptilum trigonipalpum 

 and of Cyrto.vipha gundlochi was beaten. 



Live Oak Groves. 

 Useppa Island is in part considerably elevated and on this 

 ridge are found numerous live oaks (Qiiercus virginiana) and 

 cabbage palmettoes (Sabal palmetto). This area is compar- 

 able with the oak groves on the borders of the hammock at 

 Miami. Few Orthoptera, and only well known species, were 

 found during the day, but at night Pyrgocorypha uncinata was 

 to be heard everywhere in the tops of the palmettoes and
