ZOOLOGY INSECTS. 



species. I have been unable to decide positively in regard to this, as the 

 only copy of Gay's Fis. Hist. Chili to which I have had access wants the 

 plate on which this species is figured. By a letter recently received from 

 Dr. E. C. Reed, of the Museo Nacional, Santiago, I learn a package of 

 Chilian Acridida has been forwarded to me. From this I may be able to 

 determine this point. I have received the package since the above was 

 written and in it find a specimen of the latter species, but it is so badly 

 damaged that I am unable to decide with certainty as to the identity of the 

 two, yet it is evident they are closely allied. 



Although I collected this species along the eastern base of the Rocky 

 Mountains, I did not have my attention called specially to it at the time my 

 collection was made ; nor was I aware it existed beyond the mountains 

 until I found it in the collection of 1871. 



OEDIPODA CINCTA, Thos. 

 (Edipoda cincta, THOS., Proc. Acad. Nat. Sci. Phila., 1870, 80. 



There is but one rather small specimen of this species in the collection. 



OEDIPODA BELFRAGII, Stal. 

 (Edipoda belfragii, STAL., Recensio, 129. 



This is a new species described by Stal as coming from Illinois. In 

 order to call the attention of our western entomologists to it, I give the 

 author's description in full. 



"Fuscous-brown; the head variegated with cinei'eous ; carina of the 

 head and of the posterior femora, also the posterior margin of the pronotum, 

 sprinkled with black ; antennae annulated with fuscous. Pronotum with the 

 posterior margin acute-angled ; crest somewhat prominent, profoundly 

 incised between the lobes. Elytra pale grayish-brown, somewhat translu- 

 cent 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; apex transparent, with fuscous veins. Anterior legs 

 subannulated with fuscous; posterior femora with the fascia and apex black, 

 the inferior margin and exterior side hairy; posterior tibiae pale yellowish, 

 fuscous at the base, spines tipped with black, hairy.
