SUBFAMILY I. TRYXALINJE. 209 



Ten species of the genus are listed by Kirby (1910, 107), of 

 which four occur in the United States, the others in Mexico. But 

 one is known from our territory.

This prettily colored locust is nowhere common in Indiana, 

 having been taken sparingly only in the southern half of the State 

 and Tippecanoe Co. in the north. Tt frequents, for the most part, 

 high, open uplands, where the soil is poor and covered with scant 

 vegetation, though it is sometimes found in timothy meadows and 

 along roadsides where the grass has been cropped short. But 

 few individuals have been noted in any one locality. It reaches 

 maturity about August 1st. The males differ so much in size and 

 color from the other sex that they are very apt to be considered 

 a distinct species. As the slender legs indicate, the movements 

 are made mostly by the wings, the flight being rapid and noiseless. 



In Florida it appears to be widely distributed through the 

 northern part of the State, numerous records having been made 

 as far south as' Gainesville. Below that place, so far as known, 

 only two specimens, both females, have been taken, one at Miami 

 by R. & H., Sept. 1, which measured 45.2 mm. in length, the other 

 by the writer at Dunedin, Dec. 24. There it occurs on wire grass 

 in open pine woods.
