of the stridulating vein, while in the other this coloration is decided 

 only in spots, one proximad, one distad, and one immediately distad 

 of the stridulating vein. One male from Homestead is quite brown- 

 ish, two females from the same locality are dull straw colored or 

 washed with brownish, while two Detroit females are much tinged 

 on the pronotum and proximad on the tegmina with pale reddish- 

 brown. A half-grown nymph from Miami, Fla., taken March 28, 

 1910, gives us an idea of the condition of individuals of the species 

 at that time of year. 



At Homestead this species occurred locally on the prairie-like 

 everglades, where they were scarce in the daytime, but plentiful at 

 night, perched on the grasses, stridulating fearlessly. Their note is 

 an indescribable buzz and click. The Detroit specimens were taken 

 in pine woods on the edge of a hammock, and on Big Pine Key the 

 species was beaten from green bushes in the pine woods. Two 

 specimens were found dead in spider-webs at the railroad station 

 at Homestead on July 10. 



Amblycorypha uhleri St41. 



Homestead, Fla., July 10-12, 1912; 5 c^, 6 9 . 



When compared with Texan material of this species, the present 

 series is seen to be identical, although the size is much greater than 

 in individuals from New Jersey, which, however, show no specific 

 differences from Texan topotypes. When careful examination of 

 all the available material has been made, it will probably be found 

 that the size regularly decreases northward. All of the males and 

 several of the females have much of the pronotum, pleura, and 

 proximal portion of the tegmina more or less ochraceous. Four of 

 the males have the blackish tympanal maculation decided. The 

 species was fairly common at Homestead, more numerous at night 

 than in the daytime, always in the pine woods and in or near large- 

 leaved small bushes of several species. When search was made for 

 them at night with the aid of a flash-lamp, they proved to be quite 

 shy, flying frequently before their exact location could be ascertained. 

 Two specimens were taken from spider-webs on the station building 

 at Homestead, July 10. 



Microcentrum rhombifolium (Saussure). 



Key West, Fla., July 3, 1912; 1 d". 



The present specimen was taken from high bushes about twelve 

 feet from the ground, several others being heard in the same vicin'ty. 

 This is the first record of this widespread species from the keys.
