This insect seems to De quite var tioie oorli m size and 

 color and is distributed over a considerable portion of the 

 Republic from the Pampa Ceatral and extending into 

 Ura.o'uay to the eastward. Whether or not it will prove 

 to be the insect decsribed by Blanchard as Oe(Ji[)od(( 

 sif/ndfipejniis I cannot say since I have not access to his de- 

 scription. ,^ Dr. ^Berg- of the National Museum in Buenos 

 Aires has written an article for the Stettiner Entomologische 

 Zeitschrift in which he mentions certain Orthojitera from 

 the Pamapa Central one of which he doubtfully refers 

 to Stoiobothrus .sU/iKtt/peiniis, and for this reason I am not 

 quite certain but that he refers to the j^resent insect.
