This species was first noted in Indiana about the margins of the 

 ''Groose Pond," Vigo County, on October 11, 1901. It at once at- 

 tracted attention on account of the length of the male antenna, 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 vegeta- 

 tion, and here this Paroxya flourished in company with Truxalis 

 hrevicornis and Bicromorplia viridis, while a few feet away Leptysma 

 marginicollis found a suitable home among the rushes and sedges 

 still standing. Both sexes of P. hoosieri were very active, leaping 

 vigorously when approached, and difficult to capture except by 

 throwing the net over them as they rested on the ground. The fe- 

 males were exceedingly difficult to kill in the cyanide bottle, "com- 

 ing to" after having been kept in it for several hours, although the 

 males were killed in a few minutes. On October 27th, the spot was 

 again visited, and, although several heavy frosts had occurred, yet 

 the species 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 species has been found to be rather common in 

 the western and northern portions of the State, having been taken 

 in Gibson, Fulton, Starke, Lake, Kosciusko, Steuben, Whitley and 

 Wells counties, and also by Mr. Lynds Jones near Oberlin, Ohio. 

 In all these localities it occurs about the borders of marshes, espe- 

 cially those bordering the lakes and tamarack bogs of the north. 

 In Gibson Countv it was found mature on July 10th.
