many Illinois specimens referred to it do not belong to the species. I 
think Trimerotropis verruculata , although placed by Mr. Scudder in a 
different genus, is in fact but a variety of this species ; yet as there is 
some doubt on this point I give them as distinct.

Oedipoda collaris, Scudd., Geol. Surv. Neb., 250. 
Spharagemon collare, Scudd., Proc. Bost. Soc. Nat. Hist., 
XVII, 1874-5. 
Has been taken in the northern part of the state, but I am inclined 
to think it is very rare. 
23. Trimerotropis verruculata, Kirby.

Oedipoda latipennis, Uhler., Harr. Hep., 178. 
Trimerotropis verruculata, Scudd., Geol. Surv, N. Hamp., 1, 877. 
Limited chiefly to the northern section, but has been obtained in the 
southern. 
24. Encoptolophus sordidus, Burm. 
Oedipoda sordida, Burm., Hanb. Ent , II, 648.

25. Oedipoda Carolina, Linn.

carolinus, Fab., Ent. Syst., II, 58. 
Acrydium carolinum, Deg., Ins., Ill, 491, PI. 41, Figs. 2& 3. 
carolinum, Pal. Beav., Ins., 147, PI. 4, Fig. 6. 
Locusta Carolina, Harr. Bep., 176, PI. 3, Fig. 3. 
caroliniana, Catesby, Nat. Hist. Car., II, 89, Tab. 89. 
Common throughout the state. 
26. Oe. neglecta, Thos.

Hippiscus neglectus, Scudd, Bull. Geol. Surv. Terr., Vol. II, No. 
3, 1876, 264. 
I have captured this species in southern Illinois, but think it is very 
rarely found here.
