Three Synchloes, Their Differences and Relations 



(Lcp.).

A casual examination of a series of Synchloe lacinia form 

 saundersii from Argentina so impressed the authors by the 

 similarity of this form to our californica (Wright) that we 

 decided to make a somewhat detailed comparison of these two 

 forms and also of lacinia (Hiibn.). 



We are indebted to Mr. J. R. Haskin for the loan of a 

 series of californica and lacinia, and to Dr. E. Giacomelli for 

 a series of saundersii from Argentina. Mr. Wright's "But- 

 terflies of the West Coast" and Dr. G. B. Longstaff's "But- 

 terfly Hunting in Many Lands" furnished us with informa- 

 tion as to habitat, and other data. In the ENTOMOLOGICAL 

 NEWS, Volume 25, page 303, Mr. Haskin gives a description 

 and account of californica. 



Upper side, primaries: The marginal buff spots in californica are 

 larger and more distinct than in saundersii; in lacinia they are white 

 and less distinct. In all, the fifth, sixth and seventh spots are always 

 present and most distinct. 



The buff median band in californica and saundersii is even in width 

 across the wing ; in lacinia it is narrower at the anterior part. 



The fifth spot of the band in californica is generally small, in lacinia 

 it is smaller, but in saundersii this spot is large and elongated out- 

 wardly to envelop the white spot of the submarginal row, and some- 

 times extends to the buff spot of the marginal row. 



The three basal spots are very much larger in saundersii than in 

 either of the others. 



Secondaries: The marginal buff spots in californica are always 

 large, in saundersii they are, in some, large and distinct and, in others, 

 small and indistinct ; in lacinia they are always very faint. 



The buff median band in californica is similar to that of lacinia; in 

 saundersii it generally extends to the basal angle, but sometimes it is 

 stopped by a narrow black band, one-third the distance from base to 

 margin. 



In californica the basal area is brownish-black with one small buff 

 spot in the cell; in lacinia there are two spots in the cell while in 

 saundersii the spot is so large as to take the place of the brownish- 

 black area almost entirely.
