 fig. 9. [Surinam.] 



Surubres river at San Mateo, altitude 250 meters. Esparta, altitude 

 50 meters. February, 1905. [No. 83.] (P. Biolley.) Male and 

 female. 



As far as can be determined from the descriptions these specimens 

 appear referable to this species, but probably will represent a closely 

 allied form when compared with typical Surinam individuals. The 

 lateral bars are not sharply separated from the wine-color of the 

 dorsum, but present a strong contrast with the yellowish of the ventral 

 portions. 



The genus Cornops as defined by StaP- appear to agree better with 

 these specimens than does Scudder's description. This may be due 

 to the fact that Stal's description was based on longipenne. 



SCHISTOCERCA St^l. 

 Schistocerca pyramidata Scudder. 



San Jose, altitude 1,160 meters. November, 1904. [Nos. 72 and 73-1

Some of the above recorded individuals have the tegmina consider- 

 ably longer than others, while the variation in the intensity of the 

 coloration is quite striking.
