THE CANADIAN ENTOMOLOGIST. 



taches oblongues, egalement fauves ; et enfin, plus proche de la base, on 

 compte 3 ou 4 taches peu distinctes. En dessous, les ailes superieures 

 offrent de plus, outre le dessin du dessus, une range'e de petites taches 

 blanchatres qui part du sommet et le long du bord externe ; la base est 

 fauve, presentant les trois taches blanchatres du dessus, entourees d'une 

 ligne noire. Les ailes inferieures different du dessus, en ce qu'elles 

 pre'sentent de plus une band de taches blanc-jaunatres, le long du bord 

 externe ; la bande qui traverse le disque de I'aile est forme'e de taches 

 oblongues dun blanc jaunatre comme en dessus, mais borde'es de noir 

 infe'rieurement et d'un simple lisere de cette teinte anterieurement; la base 

 present une bande de taches, en rayons, etroites, surtout les plus internes, 

 d'un blanc jaunatre, un autre plus bas au milieu, le tout reposant sur un 

 fond fauve." The type locality is given as Nicaragua. 



Edwards, in 1870 (Trans. Ent. Soc. Phila., Vol. 3, p. 191), described 

 M. ihekla, " taken by Dr. E. Swart in So. Calif.," and which has since 

 been found to occur commonly in Arizona and Texas. I know of no 

 definite locality for thekla in California, and Mr. W. G. Wright (Butt. West 

 Coast) has apparently never met with it in this State. Bollii Edwards 

 was published in Field and Forest, Vol. 3, p. loi, 1877, and is a synonym 

 o{ thekla, as Dr. Holland, who possesses the types of both, has pointed 

 out. Dr. Scudder, in his Synonymic List of the Butterflies of North 

 America, Bull. Buff. Soc. Nat. Sciences, Vol. II, p. 265, 1875, gives for 

 the habitat oi theona, which with leanira and thekla, he places in his genus 

 Thessalia, "So. Cal., Nicaragua and Guatemala." Boisduval, in the classic 

 Lepidopteres de la California, p. 55, i86g, says of theona that " Cette 

 espece tres commune dans certaines localite's du Mexique, a ete retrouve'e 

 dans la Sonora par M. Lorquin." Sonora evidently is referable to 

 Southern California. I have long suspected that our M. thekla is a pure 

 synonym of theona. Certainly the description of theona is applicable to 

 either thekla or bollii, and furthermore, Godman and Salvin, in the 

 Biologica Cent. Americana, state that specimens of bollii and thekla from 

 northern Sonora are not distinguishable from theona, except in being 

 somewhat more fulvous. It is quite obvious then that thekla and bollii 

 must be relegated to the synonymy of theona, which has long priority. It 

 is a matter of astonishment that this group should have stood erroneously 

 so long in our lists. Dr. Skinner (Cat. Rhop.) does not include theo?ia in 

 our fauna, but later in his first supplement (p. 9) he lists theojia var.
