DISTRIBUTION OF COLEOPTERA. 105 



95. Hydrobius fuscipes Linn., seriatus inscnlptus, regularis Lee. (P. vii, 372). 



Very variable aud widely distributed in temperate and boreal 

 America. Alaska to Hudson Bay, southward to California ; through 

 the Rocky Mountains to New Mexico. On the Atlantic slope it ex- 

 tends south to Maryland and West Virginia, from which I have 

 specimens. General in Europe. Kamtschatka, east and west Siberia. 

 Turkestan. P. Am. P. xiii, 135 ; Heyden, G2. 



96. Sphseridium scarabseoides Linn. 



A specimen of this species was once taken in Canada (C. 73), but 

 its subsequent occurrence is unknown. It is quite common through- 

 out Europe, and is found in many places in Turcomania, east and 

 west Siberia. Heyden, 68 ; Heyden, 1885. 



97. Cercyon. 



The species of this genus are mostly neglected by collectors in this 

 country, as it has not yet been studied by any of our systematists, 

 hence the record of the distribution of the species is very meagre, 

 and fails to furnish more than a remote approximation. 



98. C. flavipes Fab. 



Michigan (Detroit ; Marquette), Schwarz. I take it here in Penn- 

 sylvania. Europe. AVest Siberia (Kurejka). Heyden, 63. 



99. C. melanocephalum Linn. 



Europe. Asia (lekatrinburg, in eastern Ural). Heyden, 63. 



100. C. centrimaculatum Sturm., Mundum Mels. 



District of Columbia, Ulke ; Pennsylvania, Michigan (Detroit and 

 Marquette), ScJuvarz. Central and northern Europe. P. vii, 374. 



101. C. pygmseum III. 



Ottawa., Canada, Ha7Tington ; Vermont, RoberU. Europe. Voro- 

 gova, on the Jenisei, in Arctic Siberia, west Siberia. Heyden, 63. 



102. C. unipunctatum Linn. 



Michigan, Schivurz; Canada, Harrington. I have seen it here 

 several times in great abundance under carrion, or putrid substances. 

 Europe. Asiatic Siberia (Kolmogorova), west Siberia. Heyden, 63.
