Three Synchlocs, Their Differences and Relations 



(Lep.). 



By Victor Duram and Fordyce Grinnell, Jr., 



Los Angeles, Calif. 



A casual examination of a series of Synchloe hoMta form 

 saunderni from Argentina so impressed the authors by the 

 similarity of this form to our calif omica (Wright) that we 

 decided to make a somewhat detailed comparison of the«e two 

 forms and also of lacinia ( Htibn. ) . 



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

 series of calif omica and lacima, and to Dr. E. Giaoomelli for 

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

 terflies of the West QouKT and Dr. G. B. Longstmrs "But- 

 terfly Huntiqg in Many Lands" furnished us w-**- --'onna- 

 tu>n as to habitat, and other dau. In the £s -.ical 



News, Volume 25. page 303, Mr. Haikin gives a dcscriptioa 

 and account of caKfomica. 



Vpptr tid*. primarus: The mariirai b«ri >pnti m cmHformea are 

 larger and more diftinct than in m m i t rtS : in Isoms tbcy are white 

 aad 1«M dtftincL In aH the fifth, sixth aad scvcmh spots are always 

 present and nost distinct 



The boir median band in eaUfwmiem and tMMd*rni b even in width 

 acroM the wing: in lonnia it it narrower at the anterior part. 



The fifth spot of the band in eoKfomiem is generalljr wnall. in Iscmm 

 it is smaller, bat in tttmnderm this spot is large and rlnniatwl out- 

 wardly to envelop the white spot of dw sabanrginal row, aad ioai^ 

 times extends to the baff spot of die warginsl row. 



The three basal spots arc very noch larger in j snw rfr r jg tfMUi in 

 either of the others. 



Sfcondaries: The marginal boff spots in toKf omica are always 

 large, in Mommdfrm they are. in some, large and distinct and. in others, 

 small and indistinct; in lacimia they are always very fainL 



The boff median band in caHformUa is similar to that of laeinia; in 

 mnmi trsii it generally extends to the basal angle, but s om e tim e s it is 

 st opped by a narrow blade band nne-third the distancr from ha«e to 

 margin. 



In coHfomica the basal area m [)rownMl>bbdc with onr «mall huff 

 spot in the cell: in ladnia there are two spots in the cell while in 

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

 black area almost entirdy.
