SUBFAMILY III. LOCUSTIN.13. 339 



West of the Mississippi D. (/iicrcus ranges from Missouri, 

 southern Iowa and southeastern Nebraska southwest to Wash- 

 ington and Travis counties, Texas. It was from these Texas lo- 



o 



calities that Brunei 1 (1887, 17) secured his specimens, all nymphs, 

 and therefore not given a scientific name by him, he designating 

 them only as the "Post Oak Locust of Washington Co., Texas." 

 As noted above, Packard copied Bruner's article verbatim under 

 the name "Dendrotctti.r qucrcits Kiley Ms.," that name having 

 been given the nymphs by Kiley but unaccompanied by a descrip- 

 tion. Of the habits of the locust in Texas Bruner wrote: 



"The egg pods are deposited in the ground about the bases of trees 

 or indifferently scattered about the surface among the decaying leaves, 

 etc., like those of all other ground-laying species. The young commence 

 hatching about the middle of March, and continue to appear until into 

 April. After moulting the first time and becoming a little hardened, 

 they immediately climb up the trunks of the trees and bushes of all kinds 

 and commence feeding upon the new and tender foliage. The imago or 

 mature stage is reached by the last of May or during the first part of 

 June. 



"The species is very active and shy in all its stages of growth after 

 leaving the egg. The larva and pupa run up the trunks and along the 

 limbs of trees with considerable speed, and in this respect differ consid- 

 erably from all other species of locusts with which I am acquainted. I 

 am informed that the mature insects are also equally wild and fly like 

 birds. They feed both by day and night; and I am told by those who have 

 passed through the woods after night, when all else was quiet, that the 

 noise produced by the grinding of their jaws was not unlike the greedy 

 feeding of swine."
