The principal characters given in the original description are : 

 "Body black above, ... a rufus spot over the antennae; thorax obso- 

 letely varied each side with piceus ; posterior and lateral edges rufus : 

 scutel with the elevated cruciform line, two spots before it, and two 

 or three on each side rufus : . . . tergum, posterior edges of the seg- 

 ments rufus: beneath rufus, varied with black: . . . length to the tip 

 of the hemelytra one inch and one- fourth." Say further adds : " Mr. 

 Nuttall presented me two specimens, which he obtained on the Mis- 

 souri, and I found one on the Arkansaw " ; also : " On the prominent 

 middle of the hypostoma is a very obvious impressed line." 



The insect which he collected " on the Arkansaw," when he was 

 with Major Long's expedition to the Rocky Mountains in 1 819-1820, 

 may not have been the same species as the two specimens mentioned 

 first in the description and given to him by Nuttall, who obtained 

 them along the Missouri River. 



It next becomes important to ascertain, if possible, from what 

 locality the type specimens of Cicada rimosa were obtained, and I 

 have been to some pains to look up the original authorities. As an 

 aid to this Dr. N. L. Britton, of the New York Botanical Garden, 

 has sent to me some notes by Dr. P. A. Rydberg on the three journeys 

 made by Thomas Nuttall, the botanist, to regions west of the Mis- 

 sissippi. It was on the first of these, namely in 181 1, or Astoria ex- 

 pedition, that he collected the two specimens referred to, for the very 

 good reason that in the second expedition of 1819-1820, he went along 

 the Arkansas River, and did not touch the Missouri; and the third 

 expedition started in 1834 after Cicada rimosa had been described. 



John Bradbury, another botanist, was with the Astoria expedition, 

 and in 1817 he published in London, England, a narrative of his trav- 

 els in the interior of America. He and Nuttall accompanied Mr. 

 Hunt from St. Louis up the Missouri as far as the Arickara Indian
