SEA BEACHES. 



As on Biscayne Bay, sandy beaches were found on the 

 seaward margins of the outer islands. On these Trimero- 

 tropis acta was locally not scarce, and back of these on the 

 sand Scirtctica mannorata picta was local and few in numbers, 

 much as on Biscayne Bay. 



The following list cannot be considered in any way complete 

 for the forms present in this region in the spring 1 , but will 

 serve to indicate the majority of the species to be found on 

 these islands at this time. 



BLATTIDAE. 



Ischnoptera uhleriana fulvescens Saussure and Zehntner. Useppa 

 Id., Fla., V, 17, 1915 (H.), 1 juv. $. 



Eurycotis floridana (Walker). Useppa Id., Fla., V, 19, 1915 (H.; 

 on ground in heavy tangle after dark), 1 2. 



MANTIDAE. 



Stagmomantis Carolina (Johannson). Pineland, Pine Id., Fla., 

 V, 18, 1915 (H.), 1 very small juv. $. 



PHASMIDAE. 



Manomera tenuescens (Scudder). Pineland, Pine Id., Fla., V, 

 20, 1915 (H.; rank vegetation near sand dunes), 1 $, 1 juv. $. 



Manomera brachypyga Rehn and Hebard. Pineland, Pine Id., 

 Fla., V, 18 and 20, 1915 (H.; occasional in undergrowth of pine 

 woods, locally moderately numerous in low bayberry bushes 

 (Myrica ccrifcra)), 12 $ , 6$, 4 juv. $, I juv. $. 



This series and the specimens of M. tenuescens are of par- 

 ticular interest, taken with other material before us, in prov- 

 ing that the proportions of the abdominal segments, which 

 so readily separate adults of the two species, are of equal 

 value in separating immature examples in the later instars. 

 Moreover, the material shows that, in the immature condition, 

 the males of both species have straight, delicate in structure 

 and pilose cerci. All of the immature specimens in the present 

 series are in the instar preceding maturity. 



In the present series of adults the extremes of length are : 

 males, 66.3 to 74.8; females, 82.2 to 92.8 mm. The males 

 average much smaller than the typical males from Homestead, 

 Fla. (87.4 to 88.5 mm.), but appreciably larger than a male 

 from San Pablo, Fla. (69.6 mm.).
