TETTIGONID^J. 

 DICHOPETALA Brunner. 

 Dichopetala brevihastata Scudder. 



A single immature male taken on greasewood at an elevation of 

 4,800 feet at the mouth of Dry Canyon, Sacramento Mountains, appears 

 to belong to this species, although the identification is attended with 

 a little uncertainty owing to the immaturity of the specimen. Imma- 

 ture specimens apparently of this species were found to be fairly com- 

 mon when beating in the vicinity of the mouth of the canyon. 



HORMILIA Stal. 

 Hormilia elegans Scudder. 



Two females of this species were taken at Deming, July 20, both 

 attracted to light. One specimen of the species was found in the 

 lunch-room of the railroad station and brought to us by one of the 

 waiters. 



On comparing these specimens with the original measurements and 



with seven individuals from Florence, Arizona, it became apparent 



that specimens from the eastern side of the continental divide were 



larger than representatives from the western side. The following 



measurements may be of use when more extensive series are examined.
