islands possessing stands of pine, and not elsewhere, as the distri- 

 bution of the forms of this genus is limited by this controlling factor. 



Mermiria intertexta Scudder. 



Homestead, Fla., July 10-12, 1912; 5 d^, 1 9. 



Big Pine Key, Fla., July 6, 1912; 18 a", 1 9,7 9 n. 



Long Key, Fla., July 13, 1912; 7 d^, 3 9 . 



The present series has been compared with a male from Georgia, 

 which is one of Scuclder's types. In size the present repre- 

 sentation shows no noteworthy difference except that the Long Key 

 females are slightly smaller than the other two of that sex. In color 

 the Homestead and Big Pine Key series are very similar, with the 

 pale base color showing no greenish except in the Big Pine Key 

 female. ■ The Long Key series, on the other hand, has the pale base 

 color greenish-yellow in the males, subochraceous in the females. 

 The three individuals of the latter sex from Long Key have the 

 discoidal area of the tegmina more or less distinctly maculate, 

 superficially somewhat suggesting Bruner's M. maculipennis. In 

 all of the Big Pine Key males the dark medio-longitudinal line is 

 present on the head and pronotum, indicated but incomplete in the 

 accompanying female, indicated more or less distinctly in all of the 

 Homestead males and entirely absent in the female, indicated on the 

 head and pronotum in four Long Key males, on the head and as a 

 lining on the pronotal carina in two males and all three females, and 

 present on the head and entirely absent from the pronotum in one 

 male from the same locality. In two of the seven Big Pine Key 

 nymphs there is no indication of this line and in the others it is only 

 faintly marked. 



At Homestead the species was infrequent in high grasses near the 

 edge of the prairie-like everglade, on Long Key it was not uncommon 

 in places where high grasses grew in an open depressed area, while 

 on Big Pine Key it was taken from low plants on the edge of a man- 

 grove swamp, where the males were not infrequent, the females 

 mostly immature and but two adults of that sex seen.
