' I have not seen specimens from western Ecuador, but several authorities agree in 

 considering them not separable from true C. mexicana. I have not been able to 

 substantiate, by recent careful comparison, alleged differences between Colombian 

 examples and those from southern Mexico, Guatemala, etc. 



^Type locality probably Cordova, Vera Cruz.
