It will be noticed that whenever a European genus occurs in India or North 

 America al all, European species, or very closely allied forms, are also to be found in 

 those countries. South or East European species frequently extend to India, North 

 European species frequently reach America, while Central European species extend 

 throughout North Asia, and only in a few instances reach North America, and are 

 then usually confined to the West coast. Indeed almost every species common to the 

 Old World and North America is either Polar or Californian. 



There is still considerable doubt whether the European species of Colias, &c, which 

 are reputed North American do actnally occur there, or whether allied species may not 

 have been mistaken for them. It is also asserted, but I believe without authority, that 

 the common Vanessa; have been introduced into North America; but this is highly 

 improbable, as they are all wide-ranging insects, and do not feed on garden plants. 



Pieris Brassies is replaced by P. Cheiranthi in the Canaries, and by P. Biassi- 

 coides in Abyssinia. P. Rapaj has been lately introduced into Canada. May not 

 Anthocharis Creusa be an American variety of the widely distributed and very variable 

 A. Belia ? A. Ansonia is the only variety of Belia which I know to occur in America ; 

 does it, or any other variety of this species, occur in North Asia? Gonepteryx 

 Cleopatra appears distinct from G. Rbamni. Is G. Cleobule, from the Canaries, 

 distinct from G. Cleopatra? The European Colias Myrmidone is very distinct from 

 C. Edusa; I doubt the occurrence of the true Myrmidone in India. Perhaps the 

 intermediate Indian form may indicate that these two should be united, as Paruassius 

 Apollo and P. Delius, though perfectly distinct in Europe, appear to blend completely 

 into each other in Siberia. Is Lasiommata Menava sufficiently distinct from L. Hiera ? 

 Hipparchia Baldiva has been erroueously placed in the genus Lasiommata or Amecera. 

 Polyommatus Bscticus and Telicanus are among the very few species common to 

 Europe and South Africa; P. Pheretes is represented in North-East Asia by the 

 var. (?) P. Pheretiades.''— J. W. D. 



Sedge Warbler hi Dry Places. — Bearing in mind the remarks of one or more of 

 your correspondents, and a letter of my own in the 'Zoologist' for I860, upon the 

 resort of the sedge warbler to dry places, and especially to lilacs in such places, 

 I wish to report that I have this summer, as in 1866 and 1867, very frequently heard 

 and seen what must be either that or a closely-allied species, near Twickenham, away 

 from the river, and always in lilacs. During the first ten days of this present month, 

 a time of great heat, I heard it daily in some of these shrubs planted close to a brick 

 wall, on its south side exposed to the mid-day sun, as hot and as dry a position as
