ZOOLOGY <7 



Sandia Mts. where oaks are abundant. Less so in the 

 Jemez and on Mt. Taylor where the oaks are not as common. 



Adelpha californica. 



Plestia dorus. 



Thanaos persius, Scudd. 



Thecla darnon discoidalis, Skinner. 



* Thecla halesus, Cramer. Abundant about the oaks. 



The red-bellied Horn Toad (Phrynosoma hernandesii) is 

 particularly characteristic of this association but descends 

 into the next. 



CHAPARRAL OF HIGH SLOPES AND MOUNTAIN TOPS. 



This society, although belonging to the same Pine Asso- 

 ciation differs from the typical pine forest in that the trees 

 are scattering and the herbs are somewhat different. The 

 following are particularly characteristic of this society. 



ORTHOPTERA 



Arphia arcta. Descends to the Cedar Association. This 

 and the next are particularly noteworthy for the loud noise 

 that they can make comparable with an active boy, a stick, 

 and a picket fence. They make this loud crackling only 

 on the wing and while the sun is shining and often a con- 

 siderable number at the same time i. e. one starting up 

 seems to excite the others. These concerts would seem to be 

 of the nature of courtship performances although Sharp in 

 the Cambridge Natural History states that the reason for 

 these performances so common among Orthoptera is obscure. 



Circotettix undulatus. Makes the loudest noise of any in 

 our region. Very rare outside of the Yellow Pine Ass'n. 



Hippiscus neglectus. One only (N). 



H. tuberculatus. "King Grasshopper." One only. 



Trimerotropis ferruginea. Not common. 



COLEOPTERA 



Anthoxia aeneogaster, Lap. "Common in northern N. M." 



HYMENOPTERA. 



Megachile fortis, Cr. 



Melissodes grindeliae. These bees were taken from the 

 blossoms of Pentstemon where they had retired for the night 

 and were perfectly inactive when found s about 6 P. M.
