116 NATURAL RESOURCES SURVEY 



an open field for some biologist of the university, for, as far 

 as I know, the Manzanos have not been visited by any en- 

 tomologist. 



SAN MATED RANGE 



This range of which Mt. Taylor is the culmination is also 

 isolated but connected apparently with the Jemez (Nacimien- 

 tos) by the Pinon Assn. via. Cabezon and with more south- 

 ern ranges by means of the Cedar Assn. 



Here occur a few species present in the Jemez but absent 

 from the Sandias. Salpa, the alder, v and Rudbeckia are 

 examples. 



The presence here again of the Alligator Juniper, on a 

 Range directly west of the Sandias is interesting in connec- 

 tion with the more southern ranges. 



Around the base of this mountain are two species of Meloe 

 which do not occur in similar associations about Albu- 

 querque. One is apparently the same species figured in 

 Kellog's "American Insects" Plate II. One or two beetles 

 also suggest that some insects of California and Arizona 

 relationships reach their most eastern points here. 



A few species creep down the Rio Grande Valley from the 

 north that are absent from the Sandia Mts., although pre- 

 sent at Albuquerque. We note: 



Ceresa albidosparsa. 



Gelastocoris oculata. 



Camula pellucida? 



Diplotaxis punctata. 



Megilla vittigera. 



Contrasting markedly with these cases of isolated habitats 

 from which apparently suitable animals are absent, presum- 

 ably have not been able to get there; is the distribution of 

 the Lubberly Locust, Brachystola magna, which invariably 

 occupies all of those shallow basin-like depressions in the 

 mesa where alone it is found, although they are in some 

 cases tens of miles apart. This is the more remarkable in 

 that this locust is entirely incapable of flight. 



Another interesting case is that of the Wild Poppy. It is 

 common in the Cedar Ass'n., about Silver City and again at 

 Taos and Wagon Mound but it is absent from the same asso- 

 ciation in the Sandias and about Mt. Taylor. The peculiar
