The female of the coral-winged locust is the largest and most 

 bulky of our Indiana Oedijmdince. The males, as the measurements 

 show, are much smaller. This locust probably occurs throughout 

 the State, but is most abundant in the southern or driftless portion, 

 where the soil is poor and the hills high; and in the northwest por- 

 tion, where the sand-covered area is extensive. It has not been noted

by mc in the richer and more level regions of thv cculral and eastern 

 portions of the State. The winter is passed in the nynipli stage, the 

 young being "curious littk; depressed, toad-like objects"' of a dull 

 leaden color. Mature examples have been taken in Monroe County 

 as early as April 20th, and in Crawford County as late as July 10th. 

 The northern examples are snuiller, darker colored, and may prob- 

 ably be found a month later. 



This locust frequents, for the most part, timothy meadows, upland 

 pastures, roadsides, and especially bare or scantily vegetated slopes 

 and sandy plains. When in flight it is very conspicuous, owing to its 

 large size and bright-colored inner wings. The males are ready and 

 active flyers, moving rapidly for quite a distance, making, meanwhile, 

 a loud rattling note which can be heard at a distance of several rods. 

 The females seldom take to wing, but leap clumsily when approached, 

 and are more readily captured. The general range of tuberculatus
