The previous Arizona records of this species were from Oak Creek 

 Canyon and base of Humphrey's Peak, Coconino County. 



This form was not uncommon in the open yellow pine groves near 

 the hotel, while in other places it was very scarce. Individuals of this 

 species seem to be unable to fly without clattering. In the afternoons 

 it was not on the wing. 



HADROTETTIX Scudder. 

 Hadrotettix trifasciatus (Say). 



A single male of this species, collected by H. A. Kaeber, July 6, 1907, 

 on the plains at the mouth of Ramsay Canyon, Huachuca Mountains, 

 has been examined. 



ANCONIA Scudder. 

 Anconia Integra Scudder. 



At both Tucson and Yuma this species was encountered, five males 

 and two females having been taken at the former locality on July 26 

 and twenty males and two females at the latter on July 27 and 28. In 

 size there is an appreciable amount of variation in the male sex, the 

 four females being quite uniform. All the females and four of the 

 Tucson males are green; all the Yuma males and one Tucson male 

 are hoary white or pale ochraceous more or less thickly overlaid with 

 maculations of olive. Several of the brownish specimens are very pale 

 and but faintly maculate, while five are strongly marked, having the 

 pronotal decussate markings pronounced. The other brownish males 

 are more or less intermediate between the two extreme types. 



Tucson is the most eastern record for this species, the previously 

 published Arizona records being from Phoenix and Bill William's Fork. 



At Tucson this species was taken among high weeds both in damp 

 and dry locations. They were very wary and alert and when missed 

 flew for some considerable distance. A preference to alighting on 

 the ground when pursued rather than on weeds and bushes was ob- 

 served, though invariably first discovered among vegetation. At Yuma 

 it was found on the greasewood covered sand flats. 



HELIASTXJS Saussure. 

 Heliastus aridus (Bruner). 



This extremely variable species is represented by specimens taken at 

 Tucson (July 26, 3 9), Sonora Road Canyon (July 25, 2 d^, 1 ?, 

 1 nymph), Sonora Road near Tucson Mountains (July 25, 1 ? ) and 

 Roeble's Ranch (July 24, 1 6^, 1 9 ). There is a great diversity in the 

 size of the Tucson females, while the coloration is of the usual vari-
