cies can only be secured after repeated and long-continued in- 

 vestigations with trowel and beating net. The interesting spe- 

 cies of the Tettigoniidae found here were, at this time of year, 

 without exception in the earlier stages of immaturity. Under 

 the bark of certain lofty trees growing in this hammock, par- 

 ticularly E.vothea paniculata and Coccolobis lauri folia, 4 a num- 

 ber of very interesting forms were found hidden during the 

 day. These could best be collected by tearing loose patches of 

 bark off with a trowel and holding a beating net beneath at the 

 same time. Six molasses jars were placed in this hammock, 

 but little material was secured in this manner. During this 

 visit unprecedentedly cold weather was encountered which 

 made night work either unsatisfactory or wholly out of the 

 question. In warm weather this method would certainly 

 prove one of the readiest means to secure a number of the de- 

 sirable species. 



MANGROVE SWAMPS. 5 



These areas were found to be by no means as barren of Or- 

 thoptera as we had supposed. Two peculiarly Antillean spe- 

 cies of Gryllidae were found in and along their borders and, 

 in addition, an undescribed species of this family was found 

 in the deep shade among the mangrove roots. A very few 

 specimens of other species of Orthoptera were encountered 

 in this environment, while everywhere above in the foliage of 

 the mangroves a Gryllid, ubiquitous in green foliage wherever 

 found in southern Florida, was heard. In summarizing we 

 would state that Orthoptera are generally very scarce in these 

 swamps, but certain of the species are not found elsewhere 

 and occasionally a species is found there locally abundant. 

 The deep shade, labyrinth of roots and presence in unpleasant 

 numbers of mosquitoes, even as early as March, make work in 

 these areas unusually difficult.

 to express our hearty thanks to Mr. Stewardson Brown of the Acad- 

 emy of Natural Sciences of Philadelphia. 



5 We here refer only to the red mangrove, Rhizophora mangle. 

 In areas of black mangrove, Azicennia nitida, or open marshy flats, 

 covered with the shoots of this tree, none of the species of Orthoptera 

 here recorded have been encountered.
