SOME INDIANA ACRIDID.E.— III. 



BY W. S. BLATCHLEY, TF.RRE HAUTE, INDIANA, 

 ( Coiituued front page 33j. ) 



Among the species of Pezotettix occuring in Indiana, there is one which 

 I have never been able to place satisfactorily to myself. In my first 

 paper on Indiana Acrididse I called it P. rotundipennis, Scudder, upon 

 the authority of Mr. S. H. Scudder, to whom specimens had been sent. 

 Afterwards other specimens were sent to Prof. Lawrence Bruner, of 

 Lincoln, Nebraska. He referred them doubtfully to P. unicolor, Thomas, 

 stating that he had never seen tinicolor, but that in his opinion they were 

 not rotundipe?inis, as they differed materially from authenticated 

 specimens of that locust in his collections from Florida. 



I then let the matter rest for three years, when, finding no description 

 agreeing with the insect, and having received nothing like it in exchange, 

 I sent a number of specimens to Mr. A. P. Morse, of Wellesley, Mass., 

 who carefully compared them with Mr. Scudder's types of rotundipennis, 

 and pronounced them different. Mr. Scudder, after a second and more 

 careful comparison, also pronounces them different. That they are not 

 unicolor anyone who will carefully compare them with Thomas's descrip- 

 tion (Syn. Acrid., 151) or with the figure of that species (PI. XLIV. Orth. 

 of Wheeler Survey, 1875) will readily ascertain. 



Taking the above facts into consideration, I believe the species to be 

 new to science, and describe it herewith as follows :

 A Pezotettix, the $ of which is below the medium in size ; the ? 

 much larger, and quite robust. The tegmina are shorter than the pronotum, 

 obovate in outline, a little longer than their greatest breadth, and reach 

 but little beyond the first abdominal ring. In the ? they are separated
