LaPorte counties. It flies rapidly for long distances, and unless carefully 

 marked down, is very difficult to detect. It varies in colour from very 

 light gray to a dark gray mottled with brown ; the darker specimens 

 being found at some distance from the lake, where there was a scattering 

 vegetation, the light-coloured ores on the pure sand of the immediate 

 shore. It was seen nowhere more than a half mile back from the water 

 margin, and then only on the bare crests of the highest sand ridges and 

 dunes. 



Melanoplus obovatipennis (Blatchley.) (C.E., XXIII. , 80; XXVI., 241.) 



In Scudder's recent monograph of the Melanopli, this species is 

 transferred from Pezotettix to Melanophis. It has been recently found 

 in Marion, Franklin, and Crawford counties, and therefore probably 

 occurs in high, dry woodlands over the southern part of the State. It 

 is also recorded by Scudder, from Kentucky, Missouri, and near Dallas, 

 Texas. 

 Melanoplus elatchleyi Scudder. (C. E., XXIII., 81 ; XXVI, , 243.) 



This is the species formerly known as Pezotettix occidentalis Bruner. 

 In Scudder's revision it was also transferred to the genus Melanoplus, in 

 which the name occidentalis was preoccupied. 



It is found from June 15th to November ist, in open woods. On 

 October 25th, 1897, two specimens were taken in Marion County, from 

 the side of a hackberry tree, Celtis occidentalis L. This is the most 

 eastern point at which it has been noted in the State. 



Melanoplus differentialls (Uhler.) (C. E., XXIII., 99.) 



The general range of this species is southern, but specimens have 

 been taken in Lake County, in the extreme north-western part of the 

 State. It is very common in the Wabash valley. 



Melanoplus punctulatus (Uhler.) (C. E., XXIV., 30 ; XXVI., 245.) 



This is the M. griseus Thos., of my former papers, Scudder having 

 determined that to be a synonym of Uhler's species. 



It has proven to be of more general distribution over the State than 

 at first supposed, having been taken in Vigo, Putnam, Montgomery, Ful- 

 ton, and Marion counties. With the exception of those formerly noted 

 as found in the tamarack swamp in Fulton County, where it was frequent, 

 but one or tv\^o specimens have been taken each season, and they in damp 

 localities in late autumn. On October 25, 1897, two specimens were
