the large number of species, sub-species, and varietal forms which are 

 found in North America and are referable to the machaon-group, to 

 regard the New World as the original center of distribution, rather 

 than Europe. The Papilionidae are represented in Europe by only a 

 couple of stragglers, one of which is P. machaon. It is on the western 

 periphery of the region occupied in migration, the center of original 

 distribution having been as indicated above. 



A great deal might be said in amplification of. and to sustain, this 

 view, but I content myself at the moment with a bald statement of my 

 general conclusion. W. J. HOLLAND, Carnegie Museum, Pittsburgh, Pa. 



A Race of Papilio troilus from Southern Florida (Lep., Rhop.). 



In the Royal Palm Hammock, at almost the extreme southern tip 

 of Florida, I found* last winter, an interesting race of Papilio troilus. 

 It is a form midway between the typical Iroilus and the var. te.vanus 

 Ehr. The enlargement of the yellow submarginal spots is not so great 

 as in tc.ranus. but they are, and particularly on the fof"e-wings, larger 

 and more brilliantly yellow than in troilus. The under side is especially 

 brilliant ; more so than either the typical troilus or te.vanus. 



The Royal Palm Hammock is an interesting place. Made a State Park 

 chiefly through the interest of Theodore Roosevelt, it is under the 

 supervision of the federated women's clubs of the State of Florida. It 

 is a bird sanctuary, and perhaps the last habitat of the great Ivory- 

 billed woodpecker. It abounds in the beautiful and interesting tree- 

 snails, Liguus, spec. ? At the time of my visit, Feb. 24-28, 1920, the 

 weather was coo! and chilly, and insect life not abundant. My first 

 insect on arriving was the P. troilus described above. In front of the 

 "Club House" is a large patch of the pretty wild verbena, and it was 

 here that I first, and always, found these butterflies, which fed greedily 

 on the purple blossoms. A .few Hesperidae were taken here, chiefly 

 P. maculata, with one P. palatka. At dusk Sphingidae were plentiful, 

 but only E. lugubria, X. tersa, A', pluto, with' one C. grotci and one 

 P. lusca. 



I also took at a common weed ( ?) one A. tantalus, probably form 

 sonata, in fine condition. Several species of Syntomidae were fairly 

 plentiful. 



Dr. Sanford took at Jupiter (Indian River), after my return North, 

 an interesting variation of P. troilus ah. radialiis Strecker, which is 

 now in my collection. This specimen is in general much like the typical 

 texanus, but more intensely colored. The submarginal spots on the 

 secondaries above are so enlarged that the black area between them 

 and the marginal lunules is reduced to a mere line. The corresponding 

 orange spots below are of large size and intense brilliancy. The second 

 and third submarginal spots from anal angle, on the secondaries above, 

 are prolonged into the discal area, being rather "rays" than spots, but 

 only these two are so prolonged. WM. C. Woon, New York.
