abundance and Pseudosermyle straminea and truncata were taken, the 

 former in numbers, the latter sparingly. As Deming is a considerable 

 distance from the greasewood slopes at the bases of the nearest moun- 

 tains (Florida and Cook's ranges), those areas were too distant to be 

 examined on foot. 



The interesting roach Homceogamia eiratica was found at night 

 about lights in the town, while Hormilia eleyans was attracted the same 

 way. 



Florida Mountains, Luna County, New Mexico. Altitude, 4,500 to 

 5,500 feet, July 19, 1907. 



By driving fourteen miles across the mesquite plain from Deming 

 and ascending the gradual greasewood slopes the Florida Mountains 

 were reached. Various stops on the way revealed nothing of special 

 interest in either the mesquite or greasewood areas. A canyon at the 

 north end of the range, extending southwest under the towering bulk 

 of Capitol Dome, was our objective point. A small spring which trick- 

 led a short distance over the rocks before disappearing proved very 

 attractive to Telmatettix aztecus, which was present in numbers on 

 the damp spots. The slopes of the canyon were rugged and steep, but 

 we ascended the east face to about 5,500 feet elevation. On the semi- 

 barren slope, with here and there a holly-like scrub oak and numerous 

 scattered mountain bushes, the former often with a precarious hold be- 

 tween boulders, Orthoptera were not uncommon and in character were 

 very interesting. Among the species found were Yersinia solitaria, Mer- 

 miria texana, Melanoplus aridus, Mestobregma plattei and Trimero- 

 tropis cyaneipennis. The steepness of the ascent and the short length 

 of time at our disposal prevented us from reaching the summit of the 

 mountains. The slopes at the foot of the mountains did not yield 

 even moderately good collecting and but two or three common species 

 were taken. 



Silver City, Grant County, New Mexico. Altitude, 5,900 feet. 

 July 20, 1907. 



About one-half day was spent at Silver City, collecting on the rounded 

 hills west of the town. Various short grasses scantily covered the 

 tops and slopes of these hills, with here and there in the ravines and 

 valleys clumps of juniper. Collecting was not very productive, the 

 only species worthy of note being Aulocara rufum (the first New Mexi- 

 can record), Cordillacris apache, Stirapleura pusilla and Trimerotropis 

 melanoptera. 



Albuquerque, Bernalillo County, New Mexico. Altitude about 

 4,900 feet. September 14, 1907.
