27. Oe- belfragii, Stal, Kecens. Orth., 1, 129. 



As this species is described by Stal as new and as coming from 

 Illinois, 1 give here his description in full for the benefit of Illinois 

 naturalists : 



" Fuscous-brown ; the head variegated with cinereous ; carina of the 

 head and of the posterior femora, also the posterior margin of the pro- 

 notum sprinkled with black ; antennae annulated with fuscous. Pro- 

 notum with the posterior margin acute-angled ; crest somewhat prom- 

 inent, profoundly incised between the lobes. Elytra pale grayish- 

 brown, somewhat translucent toward the apex, where they are also 

 clouded with fuscous. Wings pale yellow at base, with a broad black 

 band across the disk arcuate and narrowed internally ; apes trans- 

 parent, with fuscous veins. Anterior legs sub-annulated with fuscous ; 

 posterior femora with the fascia and apex black, the inferior margin 

 and exterior side hairy ; posterior tibiae pale yellowish, fu.scous at the 

 base, spine tipped with black, hairy. Female, length, 25 millimeters. 

 Illinois. 



" In the structure of the head and pronotum similar to Oe. caroHna, 

 but differs in being smaller, the elytra and wings less ample, and the 

 former less densely reticulated ; the pronotum behind the middle being 

 sub-alutaceous ;. and in the color of the wings. The posterior angle of 

 the lateral lobe of the pronotum rounded." 



I am unacquainted with this species, and think the locality given is 

 a mistake, or that it is a variety of some of the trans-Mississippi 

 species which occasionally visit Illinois. 



28. Mestobregma? cincta, Thos. 



Oedipoda cincta, Thos., Proc. Acad. Nat. Sci., Phila., 1870, 80. 

 I have taken a few specimens of this species in southern Illinois, but 

 it is by no means common. I place it in this genus with doubt. 



29. Hippisctis corallipes, Hald 



Oedipoda corallipes, Hald , Stansb. Rep. Salt Lake, PI. X,Fig. 2. 



Hippiscus corallipes, Scudd. Bull. Geol. Surv. Terr., 1876, II, 26-4. 



Oedipoda rugosa, Scudd. Bost. Jour. Nat. Hist., VII, 469. 



Hippiscus rugosus, Scudd. Geol. Surv. N. Hamp., I, 377. 



Oedipoda paradoxa, Thos. Geol. Surv. Terr. 1871, 457. 



(Hippiscus paradoxus.) 



Oedipoda haldemanii, Scudd. Geol Surv., Xeb., 251. 



Hippiscus haldemanii, Scudd. Bull. Geol. Surv. Terr., 1876, 



II, 264. 



A close study of these forms for a number of years has satisfied me 



that they are all varieties i f one species The specimens found in 



Illinois are chiefly of the varitey rugosus ; but I find some which approach 



very near to paradoxus, with red or partly red wings.
