ART. 15. EE VISION OF THE MUTILLID WASPS MICKEL. 39 



In some specimens the apical silveiy band of the second tergite is 

 narrowly interrupted, while in others it is broadly interrupted. The 

 legs vary from ferruginous to black. 



This species is very closely related to profinqua Cresson. The 

 females of this species have been confused with the females of pro- 

 ■pinqua in all collections. The two may be separated by the char- 

 acters given in the key.
