being taken and a greater variety of species noticed. Work was 

 continued up the south arm of Dry Canyon to the broader valley- 

 like portion of the canyon above the spring. Here pinon (Pinus 

 edulis or cembroides) and juniper (Juniperus pachyphlcea) appeared, 

 giving the canyon bottom a park-like appearance quite different from 

 the sotol (Dasylirion) and ocotillo (Fouquieria splendens) covered 

 slopes at the canyon's mouth. In this region, which is at about 5,500 

 feet elevation, one Amblycorypha huasteca was beaten from a small 

 green tree, while on the barer slopes at the same elevation several 

 interesting species, such as Yersinia solitaria, Syrbula fuscovittata, 

 Amphitornus ornatus and Melanoplus aridus, were taken. 



At night in Alamogordo several species of Orthoptera, such as 

 Derotmema laticinctum, Trimerotropis texana and Gryllus, came to the 

 street lamps, while Coleoptera and Lepidoptera were attracted in the 

 greatest numbers. Certain species of beetles, as Cicindela lemniscata 

 and Tetracha Carolina, fairly swarmed, and the great moth Marumba 

 occidentalis was by no means uncommon. 



Cloudcroft, Sacramento Mountains, Otero County, New Mexico. 

 Altitude. 8,600 to 8,700 feet. July 14 to 16, 1907. 



This charming spot, situated on the summit of the Sacramento range, 

 does not appear to be on the mountain top except at certain points 

 of lookout, where one looks down on the long slopes and deep canyons 

 of the mountains w T hich sink into the desert plain of the Otero basin 

 or Hueco bolson as it is variously called. The Cloudcroft region is one 

 of low hills with beautiful open vales between them. The hills and 

 some of the level areas are covered with magnificent forests, chiefly 

 of Douglas fir (Pseudotsuga mucronata), western yellow pine {Pinus 

 ponderosa) and in some places aspen (Populus tremuloides) . The vales, 

 or "canyons" as they are termed by courtesy, are usually carpeted 

 with numerous grasses and in many places are veritable flower beds. 

 Many of the forest trees are of immense size, and the rich greens of the 

 region are in striking contrast to the colors of the desert but ten miles 

 away, though some thousands of feet below. In a grassy field, bounded 

 on one side by a stand of deciduous saplings and on the other by huge 

 firs, we found Gomphocerus clavatus, Melanoplus calidus and M . atlanis 

 plentiful. One specimen of Eritettix variabilis was also taken in this 

 location. Among the firs on the border of this field a single Chloealtis 

 abdominalis was heard striclulating among some low herbage near a 

 stump and was captured. The very noisy Circotettix undulatus was 

 plentiful in open spots in the forest, along the roads and on bare 

 lumbered slopes. One Melanoplus altitudinum was found in damp
