1. Truxalis BREVicoRNis, Linn. 



Pyrgomo7-pha brevicornis, Thos., Syn. Acrid, N. A., 1873, 67. 

 Truxalis brevicornis, Id., Ninth Rep. St. Ent. 111., 1880, 97. 

 Opsomala pimctipeimis, Id., Trans. 111. St. Agl. Soc, V., 1865, 447. 

 Fyrgomorpha punctiperifiis, Id., Syn. Acrid. N. A., 1873, 68. 



About a dozen specimens of this rare species were taken from tall 

 coarse grass, near the border of a pond, on Oct. 11, 1890. Its range is 

 southern, and Vigo county is, as far as known, the most northern point at 

 which it has been collected. The female varies in colour from a bright 

 pea green to a uniform rusty brown. The males, which are much smaller, 

 have the back green and the rest of the body brown. 



2. Chrysochraon viridis, Scudd. Short-winged Green Grasshopper. 



Chrysochraon viridis, Thos., Syn. Acrid. N. A., 1873, 76. 



Chloealtis viridis, Id, Ninth Rep. St. Ent. 111., 1880, 99. 



Opsomala brevipetinis, Id., Trans. 111. Agl. Soc, V., 1865, 451. 

 This species is quite frequent in the coarse grass which grows in open 

 wet places, and is also at times to be found along the borders of woods. 

 It is coloured much like the preceding, and the variations are the same. 



3. Chrysochraon conspersa, Harris. The Sprinkled Grasshopper. 



Locusta conspersa, Harris, Ins. Inj., 1862, 184. 

 Chrysochraon conspersum, Thos., Syn. Acrid. N. A., 1873, 76. 

 Chloealtis conspersa, Id., Ninth Rep. St. Ent. 111., 1880, 99. 

 Locusta abortiva, Harris, Ins. Inj., 1862, 184.
