in his "Check List," accompanies it with an interrogation point. In a 

 collection of Colorado Hemiptera which I have recently had the pleasure 

 of examining for Prof C. P. Gillette, of Fort Collins, Colorado, I found 

 a specimen which agrees in every particular with Say's description. I can 

 have no hesitation in referring it to his species, and considering it a very 

 well marked and distinct species. Say remarks "This insect is mutilated, 

 but it is a very distinct species. I obtained it on the Missouri River, when 

 with Major Long's exploring party." Say describes it under the name 

 of Thyrescoris albipennis, but it should be referred to Corimelcena.
