 This species is abundant in Southern Arizona, which locality is 

 its most northern point. It is of gentle flight, and easily caught. 

 It has but small interest for West Coast people. I have found 

 it very common at Mazatlan, in the winter. 



Genus SYNCHLOE. 



All are medium sized butterflies; of black or orange colors. 

 Most Synchloes are of semi-tropical habitat; nearly all Ameri- 

 can species are from Texas, and only one comes west as far as 

 California, so that the list for the West Coast is a short one, and 

 Synchloe has but little interest for the butterfly hunter of the West 

 Coast. 



The sex-marks are as in Melitaea. 



Food-plant of all the species is Helianthus, the common sun- 

 flower. 



208. Synchloe Lacinia.

 This butterfly is credited with being the most variable species 

 in America, being very inconstant, and showing all possible varia- 

 tions. The forms figured here and numbered 208, 209, 210, and 

 211, are supposed to be really but varying forms of one species 

 only ; I cannot say that the three higher numbers are forms of the 

 first, for that first one may be as properly called a form of some 

 one of the others. But each form can and should have a name of 

 its own, whether it may be closely or but remotely related to some 

 other. 



209. Synchloe Crocale.

This is the best known and representative form of the Arizona 



species of Synchloe. It is very abundant among the jungles of 



the sunflower about Phoenix, and can be caught in any quantity. 



You will get there all of these three forms, this and the two fol-
