form of the latter; no intermediate variety, to my knowledge, con- 

 nects the two, and I think it much more likely that the species are 

 both of equal value, and derived from Turuus. 



Dr. Behr, I am informed, considers it as a female form of Rutulus, 

 the relation being similar to that existing between Turitus and 

 Glaucus. 



This hypothesis is instantly controverted by the fact that six speci- 

 mens I have before me are all male — in fact, I have never seen a 9 j 

 although there is an example in the Coll. Ent. Society which might 

 possibly be of this sex, but the abdomen is so much mutilated, that I am 

 unable to determine with certainty, which ; in coloration, it differs 

 only in the luiiules of the hind wings being more fulvous. 



The indisputable fact that the males of this species are unlike those 

 of Rutulus, is a very strong argument that it is not a mere variety, 

 nor one likely to become merged again into the parent form, and 

 especially against its being an abnormal female condition : the opera- 

 tions of natural selection being specially operative with the latter.*

Mr. Edwards informs me that he has this species from the above 



locatity — most probable from the New Mexican sierras — it is also 



found in Texas and Mexico.

 Very variable : — In over thirty specimens examined, I have found 

 eight, very closely allied, but perfectly distinct, and seemingly con- 

 stant forms. Assuming the figure iu the " Genera" to correctly repre- 

 sent the normal type of the male, with which Mr. Edwards description 

 does not exactly agree, and correspondingly colored with which I have 

 also beeu unable to find any examples — we have the following series 

 of variations, the divergences principally existing upon the upper sur- 

 face. 



■ : " Mi-. P. R. Uliler, writes me that specimens of the female in the Museum of 

 Comp. Zoology, differ but very slightly from the male, either in color or orna- 

 mentation.
