NEW INSECTS FROM AEIZONA, AND A NEW BEE 

 FEOM MEXICO. 



By T. D. a. Cockerell, N.M. Agr.Exp.Sta. 



The following insects were taken on a recent trip to Arizona ; 

 the main result of the trip will be set forth in a Bulletin of the 

 Arizona Experiment Station, but it is thought expedient to 

 present the descriptions of the new species in an entomological 

 journal. The Penlita from Juarez was taken on the same trip, 

 and so is included.
