INSECTS OF BEULAH, NEW MEXICO. 35 



A LIST OF THE INSECTS OF BEULAH, NEW MEXICO. 



EDITED BY HENRY SKINNER. 



In the summer of 1901 I determined to go to the Rocky Mountain? 

 on a collecting expedition and vacation, and was influenced to select 

 Beulah, New Mexico, from the fact that Prof. T. D. A. Cockered 

 had taken Argynnis nitocris there. The country was represented to 

 me as interesting from a scenic standpoint and also a good place 

 entomologically. 



Beulah is situated in Sapello canon in the main range of the Rocky 

 Mountains, about thirty miles north-west of Las Vegas in San Miguel 

 County, New Mexico. The elevation of Beulah Post Office (Bark- 

 er's ranch) is about 7,250 feet. My headquarters was at Blake's 

 ranch, 8,000 feet elevation. The fauna and flora here are those of 

 the Canadian zone. The Sapello river runs through the canon and 

 at Beulah is a small but swiftly running creek. 



I arrived on the morning of August, the 9th, and left on August, 

 the 26th, thus having sixteen days collecting. Rain fell every day 

 but one during my stay. The thunder storms of the rainy season 

 usually commenced in the afternoon, and unfortunately left every- 

 thing wet for some time on the mornings following. It was gener- 

 ally ten A.. M before the vegetation was dry enough to permit fair 

 collecting. However, by hard work I managed to get a considerable 

 number of insects of all orders. Coleoptera were comparatively 

 scarce, as were also the night flying moths, and very few of the latter 

 were taken at night. The best night catch of moths was made dur- 

 ing a rain storm. No sugaring was attempted. Vegetation is pro- 

 lific, and the timber line is well toward the top of the main range 

 (11,000 feet). During the month of August the nights and morn- 

 ings are quite cool and fire is necessary for comfort. 



When I returned to Philadelphia and mounted the material col- 

 lected, I turned it over to various specialists for study and determin- 

 ation, and feel very grateful to the entomological friends who have 

 so kindly aided me. I am specially indebted to Prof. T. D. A. Cock- 

 erell, who generously placed in my hands all his valuable records. 

 In addition to his own collecting he also includes the material cap- 

 tured by Willmatte Porter (now Mrs. Cockered), and his late son. 

 Martin D. Cockerel!. This material he had determined by students
