o'J2 The New Mexico Bees of the Genus Borabus. 



Meritzelia Rushyi [C. H. T. Toionsend). Many workers were 

 taken on the Priaiefla. Those from (he MentzeUa are laden 

 with pollen. This species ( ? ) was also taken by j\Ir. C. M. 

 Barber on the Rio Ruidoso, Aug. 28, and by Mr. Otis at the 

 31escalero Agency. 



This is very close to B. Edwardsii, Cresson, but differs in 



the 5 having the first two abdominal segments yellow. The 



? var. from Beulah connects the typical prunelhe ? with 



Edwardsii, and it may be that the insects will be t'o.und to 



intcrgrade. B. Putiuvni, Cress., seems also allied.
