plant is Zamia iiitrtrrifolia Willdciiow, a plant known by tlie natives as the "coon- 

 tie." It unfortunately semis to be the general consensus of opinion among Icijidop- 

 terists that once the life-history of a butterfly has been published there remains 

 nothing to be known of that species. Mere stereotyped egg, larval, pupal descrip- 

 tions do not, however, constitute tlie full biology. The late lamented W. H. Ed- 

 wards created a wonderful change in our knowledge of Rhopalocera, but to the 

 present and future generations there still remains an ever increasing field of 

 observation. 



Thecla simaethis Drury 

 This species has apparently been recorded in our fauna from Texas only, but 

 I have recently seen a specimen in the collection of Mr. F. Grinnell, Jr., from the 

 Chirachua mountains of Cochise county, Arizona, collected there by Mr. Virgil 

 Owen. It was taken April 1 1, 1906. 



Papilio mylotes 



This is given in our catalogues as inhabitating Southern California, on the au- 

 thority of Reakirt. Strecker, Cat., p. 68, 1878, in a note under mylotes says: "Two 

 males, formerly in coll. Tyron Reakirt, were taken in Southern California and re- 

 ceived from Dr. Heerman in 1862." I can see no reason for still retaining this 

 species in our faunal lists, for had it really occurred here it certainly would have 

 been again met with long before this. Moreover, Reakirt, as is well known, was 

 notoriously careless in his handling of data. In the Proc. Ent. Soc. Ph., Vol. V, 

 1865, he records, p. 219? Ceratinia ly caste from Los Angeles, California, and de- 

 scribes var. negreta from the same locality. Further, p. 223, he publishes Mechan- 

 iis californica from Los Angeles. Negreta is but an individual variant, and M. 

 californica is a local form of the protean M. polymnia Linnsus. None of these 

 have been taken within the limits of the United States, and until definite captures 

 are reported they should not be given a place in our lists. 



P. mylotes has a considerable synonymy, embracing P. Caleli Reakirt, P. tonila 

 Reakirt, P. alcamedes Felder, P. aristomenes Felder, and P. eurhnedes Boisduval. 



It occurs in Mexico, Guatemala, Honduras, Nicaragua and Costa Rica, and is a 

 close ally of P. iphidamas, and very probably but a local form of P. eurimedes 

 from Guiana. 



Euchloe sara Boisd. 

 The Pierid genus Euchloe, so far as my experience goes, is remarkably free 

 from aberrations, although it is notorious for the variation and dimorphism dis- 

 played. I have taken hundreds of E. aiisonides and E. sara, and a few E. lanceo- 

 lata australis, but only once have I met with a true monstrosity. This sport of E. 

 sara, form reakirtii, I netted in Millard canyon, on the west slope of the San Ga- 

 briel mountains, on March 28 last. It is strikinglj' weird and, I believe, worthy 

 of notice. The primaries differ at once from normal examples in being more 

 elongate, the outer margin somewhat incurved, and the apex sharply cut. In the 

 cell is a large quadrate black bar, and from it runs the usual orange patch, but 

 the coloration is decidedly different from that of the normal example. Along the 

 outer margin, nearly to the inner margin, is a wide, jet black margin^ rounding
