" peeur.'' No nests were found, hut a female shot Mav 17 was 

 laying. 



In my preliminary announcement* of the occurrence of this species in 

 Arizona I inadvertently gave the number of specimens as eight, whereas 

 nine were really obtained. These show little variation in color or mark- 

 ings, but the females are slightly smaller than the males. The characters 

 which separate M. lazvreiicii from !ts respective allies, M. tristis of Ja- 

 maica and M. 7iigricapillus of Central America, are well maintained in 

 this series.
