the N. M. form is perhaps a distinct race, as all have the markings 

 yellow, whereas the typical form from Nevada has them white. 



(5.) Anthidium emarginatuni, Say. — Taken in 1867 by Dr. Lewis, 

 and described by Cresson as atrifrons. 



(6.) Anthidiutti interruptum, Say. — Las Cruces, N. M., and Chaves, 

 N. M.: four, all taken by Prof. Townsend. Determined by Mr. Fox. 



(7.) Anthidium inaculi/rons, Smith. — Taken in 1867 by Dr. Lewis. 

 One taken by Prof. Townsend in Soledad Canon, Organ Mts., Aug. 15, 

 1896, on plant No. 40. 



(8.) Anthidium jnaculosum, Cress. — Tuerto Mtn., near Santa Fe, 

 8,025 feet, Aug. 7, on flowers of Senecio. Besides the difference in the 

 markings, this differs from the last in the abdominal punctation. 



There is in New Mexico another bee which might easily be taken 

 for a small Anthidium, namely Stelis costalis, Cresson. This is a very 

 variable species, both as to size and colour. It was taken by Prof. 

 Townsend on the West Fork of the Gila R., July 16, and by me at Santa 

 Fe, on flowers oi Rudbcckia laciniata, July 19. It is the only Stelis yet 

 observed in New Mexico.
