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. 



22. S. collare, Scudd. 



Oedipoda collaris, Scudd., Gleol. 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 verrticulata, Kirbt. 



Locusta verruculata, Kirby, Faun. Bor. Am. Ins., 250. 



latipennis, Harr. Kep., 179.

 Oedipoda latipennis, Uhler., Harr. Rep., 178. 

 Trimerotropis verruculata, Scudd., Geol. Surv, N. Hamp., 1, 377. 

 Limited chiefly to the northern section, but has been obtained in the 

 southern. 



24. Encoptolophus sordidus, Bubm. 



Oedipoda sordida, Burm., Hanb. Ent., II, 643. 

 Acridium (Oedipoda) sordidum, De Haan. Bijdr. Kenn. Orth., 143. 

 Locusta nebulosa, Harr., Rep., 181. 

 Oedipoda nebulosa, Erichs, Archiv. f. Nat. II, 230. 

 Locusta periscelidis, Harr, Cat., 56. 

 Tragocephala sordida, Stal., Recens. Orth., I, 119. 

 Encoptolophus sordida, Scudd., Proc. Bost. Soc. Nat. Hist., 

 XVII, 1874-5. 

 Found occasionally throughout the state. 



25. Oedipoda Carolina, Linn. 



Grryllus (Locusta) Carolina, Linn, Syst. Nat. I., 701. 

 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. Rep., 176, PI. 3, Fig. 3. 



caroliniana, Catesby, Nat. Hist. Car., II, 89, Tab. 89. 

 Common throughout the state. 



26. Oe. neglecta, Thos. 



Oedipoda neglecta, Thos., Proc. Acad. Nat. Sci., Phila., 1870, 84. 

 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.
