 also some white spots opposite the tip, where the black border is 

 considerably dilated. Underneath, these wings are nearly the 

 same as on the upper side, except that the terminal band is less 

 marked and the spots by which it is divided are arrow-shaped, and 

 pearly white. The posterior wings are bluish-black, with the base 

 reddish-brown, traversed, behind the central cell by two rows of 

 large white spots, the outer of which are yellow in the male : un-

 is brown, marked with about 22 pearly white spots, arranged in 

 four rows, parallel to the hind margin ; the seven composing the 

 marginal row are somewhat crescent-shaped, and those of the next 

 row, which crosses the disk, wedge-shaped, each surrounded by 

 a black line, the next near the base are of different shapes ; the 

 costa, and inner margin are bordered near the base by a streak of

 Canada. It also inhabits Jamaica.

 topics of interest, partly from want of space and partly from the 

 difficulty of obtaining in time the materials required. We pro-

One of the earliest subjects which engaged the attention of the 

 Local Committee was the invitation of men of science from Europe ; 

 and large numbers of circulars, accompanied by all necessary in- 

 formation respecting routes of travel, were scattered over Great 

 Britain and the Continent. Courteous replies were received from 

 many of the institutions and gentlemen addressed, but few were ' 

 found to be able to accept the invitation. Hopes were at one time 

 entertained that Sir Roderick I. Murchison and Sir Wm. Hooker 

 would have honoured the meeting with their presence. It proved
