174 ENTOMOLOGICAL NEWS. [April, '15 



Under side, primaries: The marginal buff spots in calif ornica and 

 lacinia are always distinct; in saundersii they are small and faint. 



In calif ornica the white spots of the submarginal row are generally 

 small; in lacinia they are twice the size and in saundersii they are of 

 intermediate size. 



The yellow median band is even in width across the wing in cali- 

 f ornica and saundersii; while in lacinia it tapers off toward the anter- 

 ior part. 



In californica the base is brownish-black, except the inner half of 

 cell which is buff and a white spot in outer half of cell; in lacinia and 

 saundersii this area is brownish-black with two buff spots in the cell 

 and one between veins Cu2 and A. 



Secondaries: On the outer edge of the yellow median band in 

 lacinia and saundersii there are some spots partly detached by black 

 marks, but in californica there are no such spots. The number and 

 position of these spots vary greatly. 



The base is brownish-black; in lacinia there is a row of four buff 

 spots, and beyond this there is one spot in the cell and one between 

 veins SC and R ; in saundersii and californica there is no such spot 

 between veins SC and R. 



Habitats, californica: Goldroad, Ariz, (i), Colorado 

 Desert (4) ; 



lacinia: Georgetown, Texas (i), Southern Arizona (4); 



soMndersii: Caracas, Venezuela (2), San Juan, Trinidad 

 (2), La Rioja, Argentina (3).*

 in Many Lands" by Dr. G. B. Longstaff, (3) series from Dr.

 Wright. 



To our minds these three names represent geographical 

 forms of one species found from Argentina to California. It 

 is seen by our comparison that saundersii is closer to califor- 

 nica than it is to lacinia. To show our ideas more graphically 

 we would suggest the arrangement of these forms as follows : 



Synchloe lacinia lacinia Hiibn. 



Synchloe lacinia saundersii Doub.-Hew. 



Synchloe lacinia californica Wright. 



♦According to the catalogues of Dyar and Strecker and an article in 

 Papilio by Aaron, saundersii is found in the United States and the 

 habitat is given by Aaron as Texas.
