and a rather large dash at the outer angle along the inner 

 border ; on secondaries the marginal series of small spots

Having taken P. Tarquinius only in Florida, and 

 knowing of it only from the extreme south, I was much 

 surprised when this spring, specimens of a butterfly were 

 shown me by Mr. Packard from Aroostook Co., Me. and 

 by Mr. Verrill from Norway, Me., which bore a most 

 striking resemblance to P. Tarquinius ; subsequently and 

 since this paper was written, I have heard of it from other 

 northern localities and have myself taken it ; Mr. Emory 

 of Springfield took it near Manchester, N. H. ; specimens 

 are in the Museum of Comparative Zoology from the 

 "White Mountains, a little north of which, at Berlin Falls, I 

 have taken it and have seen a specimen from near the same 

 place collected by Mr. Treat ; the British Museum speci- 

 men comes from Nova Scotia, and latterly (see Canadian 

 Naturalist, vii : 398) it was exhibited at a gathering of 

 entomologists by Mr. Billings, of Prescott, Canada West. 

 My specimens were taken Aug. 13. (This paragraph was 

 appended after the presentation of the paper to the Insti- 

 tute.) 



Porsenna was an ally of the Tarquinians on their
