that would best agree, i. e. perse Edw., but this latter form shows cer- 

 tain features of maculation, notably on the underside of primaries 

 that do not fit in at all well with Oberthur's figure ; we figure a $ from 

 Kerrville, Texas which seems to be typical callina. It is possible of 

 course that Boisduval had two forms before him at the time of de- 

 scribing but the Sonoran types being lost we think it advisable to re- 

 strict the name to the Mexican type especially as the original descrip- 

 tion not only does not contradict this but rather seems to point in this 

 direction. It is possible that elada Hew. may take priority over cal- 

 lina Bdv. but we only know the species from Godman and Salvin's fig- 

 ure and M. Oberthur is of the opinion that the true elada is something 

 different from Godman and Salvin's conception of it (Et. de Lep. 

 Comp. IX (2) p. 80) which to us looks more like perse than callina; a 

 study of the type in the British Museum will be necessary to settle the 

 matter. Socia Feld. is another very closely related form which may 

 supplant one of our present names but a careful study of the type, 

 which is possibly in the Tring Museum, is also necessary in this case. 



M. bolli Edw. (PI. X, Figs. 5, 6). 



This species was described from a single 2 from San Antonio, 

 Texas ; in the Edwards' Collection the only specimens of both bolli 

 and thekla are from Arizona and cannot be considered as types ; in 

 Philadelphia we discovered however a 2 labelled in Edwards' hand- 

 writing 'M. bolli, S. Ant., Tex.' which is without much doubt the true 

 type. The type of thekla from S. Calif, which should be in the Smith- 

 sonian Inst, we were unable to find ; it is probably lost. These two 

 are very closely related and are without doubt forms of one species ; 

 the Texas form (Fig. 6), to which the name bolli will apply, is dis- 

 tinguished from the western form thekla (Fig. 5) (Ariz. S. Calif.) by 

 the fact that on the underside of primaries the yellow submarginal and 

 discal spots are not so sharply defined but tend to merge into the 

 ground color of the wing. Both are closely allied to the Central Am- 

 erican theona Men. ; we figure the underside of both forms. 



Phyciodes gorgone Hbn. 



Figs. 1 and 2 of Hubner's Samml. Exot. Schm. PI. 41, as stated 

 by Scudder (Buff. Bull. II, p. 266), certainly refer to the species at 

 present listed as ismeria Bdv. whilst Figs. 3 and 4 are as plainly the 

 2 of phaon Edw. If the name be held to the $ sex, gorgone Hbn.
