Sept., I9I4-] Davis: Orthoptera from Florida. 201 



It is, therefore, not remarkable that every few hundred miles a dif- 

 ferent species should appear, especially on some of the Keys like 

 Big Pine Key, which lies about thirty-five miles to the south of the 

 mainland of Florida. 



Females of five of the species are known and it is of interest that 

 the stripes that commence at the fastigium and extend backward to 

 the posterior margin of the prothorax, or on to the abdomen in some 

 individuals, are nearly parallel, whereas in the males these stripes 

 diverge as they extend backward from the head to the posterior 

 margin of the prothorax. In brown individuals there is a conspicuous 

 darker dorsal band the sides of which are either parallel or divergent 

 on the head and thorax according to sex. 



It may be well to state that the natural colors in Bcloccphalus and 

 other green Katy-did-like insects can best be preserved by placing 

 them when dead in a solution of about nineteen parts of water to one 

 of commercial formalin. They should be packed tightly enough in 

 the bottle to prevent their being jostled about in traveling, and should 

 be removed after a few weeks' stay at most in the solution. 



Scudder described Bcloccphalus suhaptcnis in the Proceedings of 

 the Boston Society of Natural History, Vol. XVII, 1875, and in a 

 paper by the writer on " Three New Species of Belocephalus from 

 Florida," this Journal, Vol. XX, p. 123, June, 1912, additional facts 

 were made known. 



The six species so far described may be separated as follows : 



Vertex of the head produced as a stout sub-cylindrical thorn tapering apically. 



Body of male about 40 mm. in length ; antennae unicolorous. The outer 



extremities of the subgenital plate not bent upward and inward, 



and not produced into points. 



Supra-anal plate with the inner sides of the V-shaped notch nearly 



straight. Hind femora about 20 mm. in length sabalis Davis. 



Supra-anal plate with the inner sides of the notch rounded. Hind 



femora about 18 mm. in length sleight i n. sp. 



Body of male about 34 mm. in length ; antennse spotted. The outer ex- 

 tremities of the subgenital plate not bent upward and inward and pro- 

 duced into sharp points snbaptenis Scudd.
