NYMPHALINAE: EUGONIA J-ALBUM. 379 



board, which had matured (hiring the passage. But a still more striking 

 instance of the occurrence of Lepidoi)tera far out at sea, on account of the 

 number of species concerned, is given in a recent number of Science 

 (ix : 340), where Mr. Lucas records that while in latitude 25° south and a 

 thousand miles from the nearest portion of the coast of Brazil his party 

 " encountered several light squalls of wind and rain, during one of which 

 two butterflies were driven past. The weather continued squally all night 

 and for part of the next day, the wind coming from the westward. The 

 following morning it was found that quite a number of Lepidoptera had 

 been blown on Iward, and ensconced themselves in various places sheltered 

 from the wind. They were mostly, if not wholly, nocturnal species of 

 small size, although one large hawk-moth was among them. About 

 twelve or fifteen specimens representing nearly as many species, were 

 captured, and others seen ; so that not less than twenty or thirty individ- 

 uals must have reached our ship." This number of specimens at so great 

 a distance is certainly very remarkable and shows that the occurrence of 

 butterflies at sea must not be looked upon as excessively rare, and explains 

 without doubt one means by which the natural distribution of butterflies 

 from one region to another may take place.
