Tomonotus carinatus, Thos. Synop. Acrid., 106. 
The first and second varieties ( sulphureus and xanthopterus ) are 
found, I believe, throughout the state, though the former largely pre- 
dominates, as far as my observations have gone ; but there is such a 
complete gradation from one to the other in all the characters by which 
they are supposed to differ, that very often it is impossible to tell to 
which a specimen belongs. The variety carinatus is found only in the 
north-west part of the state. 
20. T. tenebrosus, Scudd. 
Oedipoda tenebrosa, Scudd. Hayden’s, Geol. Surv. Neb., 251.

Arphia sanguinaria, Stal, Recens. Orth., I, 119, 
tenebrosa, Scudd. Bui. U. S. Geol. Surv., 1876. 
This is occasionally seen in the extreme north-western part of the 
state ; I have seen but one specimen collected in the state, and that 
was by Miss E. A. Smith, of Peoria.
