CHOETOPHAGA Saussure. 

 Chortophaga viridifasciata (De Geer). 



A single female of this species was taken during a train stop at Con- 

 verse, Bexar County, Texas, July 8. 



ENCOPTOLOPHUS Scudder. 

 Encoptolophus ooloradensis Brunei-. 



A pair of this interesting species was taken in dry grass along the 

 railroad tracks at Spofford, Kinney County, Texas, July 8. The species 

 was somewhat plentiful and very swift of flight. 



This is the first record of the species from Texas. 



Encoptolophus texensis Brunei-. 



In suitable locations, such as irrigated and grass prairie land, through 

 southern Arizona and New Mexico and western Texas, this species 

 will no doubt be found in fair numbers. 



In Texas, two males were collected at Spofford, July 8, while a series 

 of thirteen males and eight females were taken, July 10-11, at El Paso, 

 all except one from irrigated land. At Albuquerque three males and 

 eleven females were secured, September 14, on irrigated land, while a 

 single female was attracted to light at Deming, July 20. A pair were 

 taken in grass prairie land at Aden, July 21, while a single female was 

 taken in the greasewood belt at Alamogordo, July 13. 



The specimen from Ysleta, El Paso County, Texas, recorded as E. 

 costalis, 12 proves on re-examination to be E. texensis, which was unde- 

 scribed when this record was published. A female specimen taken at 

 Roswell, New Mexico (August, 1902, at light, T. D. A. Cockerell), 

 shows the presence of the species a considerable distance up the Pecos 

 Valley. 



In size there is a considerable amount of individual variation, a num- 

 ber of specimens of each sex being both larger and smaller than the 

 measurements given by Bruner. The dimensions of several of these 

 specimens may be of interest.
