This handsome locust was first noted in Indiana about the 

 margins of the "Goose Pond,"' Yigo Co., on October 11, 1891. It 

 at once attracted attention on account of the length of the male 

 antennae, and the black stripes on the sides of the abdomen of the 

 female. The pond was then almost dry, and the dense growth of 

 sedges and rushes which had filled its shallow margins, were, in 

 some places, burned away. Over the burned spots had sprung up 

 a dense green vegetation, and here this Paroxya flourished in com- 

 pany with Tru.rulis brcricornis and DicJiroinorplia viridis, while 

 a few feet away Lcptt/snifi iiutnilnu-ollis found a suitable home 

 among the rushes and sedges still standing. Both sexes of P. 

 Jtoofticri were very active, leaping vigorously when approached, 

 and difficult to capture except by throwing the net over them as 

 they rested on the ground. On October 27th, the spot was again 

 visited, and. although several heavy frosts had occurred, the spe- 

 cies was still fairly common. At this time, however, they were 

 all found in the small patches of grass which grew among the 

 fallen leaves a few yards from the edges of the pond proper. 



Since then the locust has been found to be rather common in 

 the western and northern portions of the State, where it occurs 

 about the borders of marshes, especially those bordering lakes 

 and tamarack bogs. In Gibson Co. it was found mature on July
