CHLOEALTIS Harris. 

 Chloealtis abdominalis (Thomas). 



■• On the edge of a field flanked by a forest of Douglas fir (Pseudotsuga 

 miicronata) at Cloudcroft, one adult male and seven immature speci- 

 mens of this species were taken on July 14. The adult specimen was 

 located by his stridulation, although it was in the middle of the after- 

 noon. The note of this insect was like that of individuals of the same 

 species heard in Michigan. 



When compared with a series of males of the species from Pequaming, 

 Michigan, Yellowstone Park, and Manitou, Colorado, the Cloudcroft 

 specimen is seen to be appreciably smaller, the measurements being 

 as follows: Length of body, 15.7 mm.; length of pronotum, 3.3 mm.; 

 length of tegmen, 8.8 mm.; length of caudal femur, 11.2 mm. 



The previous records of this species in New Mexico are from Beulah, 

 San Miguel County, and Truchas Peak, Rio Arriba-Mora Counties. 



CHORTHIPPUS Fieber. 

 Chorthippus curtipennis (Harris). 



One male and two females of this species were collected at Cloud- 

 croft on July 14 and 15. These specimens were taken in clamp grassy 

 situations, the species being by no means common. 



Beulah, San Miguel County, and Aqua Fria Park, Colfax County, 

 .are the previously known New Mexican localities for the species. 



GOMPHOCERTTS Thunberg. . 

 Gomphooerus clavatus Thomas. 



At Cloudcroft this species was found to be abundant in grassy moun- 

 tain meadows, particularly along the edges of the forest. Here a 

 series of fifteen males and sixteen females were taken on July 14 and 15. 

 It was noticed that the species was very hard to find before ten o'clock 

 in the morning, although quite abundant during the heat of the after- 

 noon. 



The series is quite uniform in size, but in color there is in a number 

 of specimens a pronounced mixing and lining with shades of brown and 

 ochre which is not seen in the other more uniformly colored indi- 

 viduals. This variable tendency is more apparent in the female sex. 

 None of the individuals from Cloudcroft present areas or even traces 

 of green in their coloration. A single female from Truchas Peak, 

 New Mexico, taken August 2, 1902, by W. P. Cockerell, examined in this 

 connection, has considerable green in its coloration. The previous 

 exact New Mexican records for the species were from Cloudcroft and 

 above timber-line, 13,000-14,000 feet, on Truchas Peak.
