explain, that those which we see are all females. The males 

 keep by themselves, and are less frequently found. 



In closing these desultory observations, I may say that I 

 shall be very glad to afford all the information that is in ray 

 power to any entomologist who may be induced by these 

 remarks to interest himself in the study of British Diptera ; 

 and I shall feel much obliged by the loan of any specimens 

 that may be entrusted to me for the purpose of examination, 

 particularly of those belonging to the Anthomyidaj, as the 

 Jiritish species of this family are very little known.

On some Amurland Insects. By Francis Walker, Esq. 



PART II. 



Motschulsky, Menetries and Stal have noticed respectively 

 the Coleoptera, Lepidoptera and Heraiptera of Amurland. 



The first author observes that nearly the whole of the new 

 species described by him belong to the most eastern part of 

 Siberia, in which region 470 species have been found. Of 

 identical species there is 1 in 30 for the Amur and 

 Central Europe, 1 in 10 for the Amur and the South 

 Oural, 1 in 6 for the Amur and the most eastern 

 Siberia. Thus, the Fauna of the western region of the 

 Amur has thrice more analogy with that of the region of the 

 Pacific, in Siberia, than with that of the South Oural, and 

 five times more than with that of Central Europe. The 

 Fauna of South Oural is comparatively poorer in species 

 than that of Central Europe and than that of the Amur 

 region. In Iceland 81 species of Coleoptera have been 

 found; in Lapland, 967; in Jakoutsk, 120; and in Kamt- 

 schatka, 130. Two are common to Iceland and Jakoutsk, 

 5 to Iceland and Kamtschatka, 37 to Jakoutsk and Swedish 

 Lapland, 33 to Jakoutsk and Kamtschatka. Thus, of iden- 

 tical species, there are I in 40 for Jakoutsk and Iceland, 1 in 

 29 for Jakoutsk and Lapland, 1 in 8 for Jakoutsk and Kamt- 

 schatka ; and the conclusion is that the Fauna of Jakoutsk 

 has five times more analogy with that of Kamtschatka than
