the two, although his material from America of angtilata was incorrectly named for him 

 " exprimens." Surely Dr. Speyer must be good authority that in Europe no variety of 

 umbra corresponding to angulata exists ! That another species of Pyrrhia exists in 

 America is proved by stilla, which is perfectly and undoubtedly a distmct species from 

 any of the others, and handsomer in colors. 



* I incline to believe in the possibility that the species of Heliothis and Pyrrhia 

 umbra have been imported by commerce ; in this case the other two American species 

 of Pyrrhia may be held as descended from a common ancestor in the Tertiary. This is 

 at the best conjecture. But I am tolerably confident that our two species, angulata and 

 stilla, are perfectly valid and distinct. 



+ This species is regarded as distinct and representative by some writers, but I can- 

 not agree with them ; the lateral abdominal tufts are the remarkable specific feature 

 common to both forms ; the larva feeds on cabbage, and 1 think it has been brought 

 over like the Cabbage Butterfly. The Heliothians may have been brought with plants, 

 but I do not feel confident of this with regard to dipsaceus and armiger ; it is more 

 likely, perhaps, with regard to scutosits^ the larva of which feeds in Europe on Artemisia 

 campestris. Probably specimens of the European Zeuzera Aesculi have occurred in 

 New York, brought by the importation of trees or in wood, but the species has not 

 spread. The Clear-wings above noted have probably been imported. There is a pur- 

 posed importation of European insects, with a view to acclimatization, going on, con- 

 ducted by collectors acting from unscientific motives. Prof. Fernald has given us a very 

 careful paper on Tinea and Tineola.
