BB. — Form very slender, considerably compressed; head strongly 

 produced. (Size rather small, cT 18-21 mm., 9 26-27.5 

 mm.), acris Rehn and Hebard. 



A single imperfect specimen from Lathrop, California, seems to 

 indicate the presence of a quite distinct species in the San Joaquin 

 valley. 



Paropomala calamus Scudder. 



Rather unexpectedly this species was encountered at three places 

 in or adjacent to the Rio Grande valley. On the bare desert slopes of 

 the Franklin Mountains at El Paso a single immature specimen was 

 taken on July 9 at an elevation of 4,500 feet; a series of six adult and 

 five immature males and nine immature females was taken at Aden, 

 July 21, while one adult male and two adult females were taken at 

 Albuquerque on September 14 in dry grass. At Aden the species was 

 taken chiefly in grass prairie land, where it was found clinging tightly 

 to blades of grass, while at Albuquerque it was found in the river 

 bottom-land. The immature specimens from Aden represent three 

 stages of growth. 



As no measurements have been published for this species the follow- 

 ing may prove of service :

 Length of head, 

 Length of pronotum, . 

 Length of tegmen, . 

 Length of caudal femur, 



The specimens from Albuquerque are all in the green phase, while 

 the Aden series and the Franklin Mountains specimen are in the pale 

 brownish and hoary white phase. The adult males from Aden and 

 nearly half the immature series have the hoary white suffusion very 

 strongly marked, usually covering the head, pronotum, pleura and 

 caudal femora. 



The only previous record of this species is that of the types from 

 Lancaster, California, in the Mohave desert. 



Paropomala virgata Scudder. 



This species appears to be one restricted to the eastern side of the 

 continental divide, the only exact records being from the Rio Grande 

 valley and the region adjacent to it. At El Paso a series of seven 

 males and one female was taken July 10-11 on irrigated land along 

 the Rio Grande and in dry grass in sand near the edge of the mesa.
