Three species (?) of GyropJicena, probably of the group UncepJialus, not 

 before known on this continent. 



JDeliphrum expansum, n. sp. Yery similar to the European D. tectum. 



Siagonium punctatum, known before only in Eastern America. 



Pseudopsis ohUterata, n. sp., remarkable by the indistinct elevated 

 ridges. 



Hydnobius^ four species, apparently parallel with the European forms. 



Uiithia; with table of four species from Western America. The 

 genus is not, however, unrepresented in the Eastern region. 



Umphylus americanus, n. sp. Genus not before represented. 



Hypocoprusformicetorum. Ai)parently not different from the European 

 species. 



Gastrallus marginipennis, n. sp. Genus not before represented. 



Fhymatodes maculicollis. Known only from Lake Superior. 



Callimus chalyhceus. Extends from California. 



JEleodes ; five species extend to a great altitude. 



Lacconotus pinicola Horn. The second species of this singular genus. 



Scolytidce. A comparatively large nuniber (19) of species. 



I have intercalated a few species from Idaho and Wyoming, which I 

 owe to the kindness of Mr. O. Eeinecke, of Buffalo, 



The following abbreviations are used in the list : V. P. ; Yeta Pass. 

 L. Y. ; La Yeta. G. ; Garland. A. ; Alamosa. The altitude of La Yeta 

 is 7,000, that of Garland 8,000, and that of Alamosa about 7,600 feet 

 above the level of the sea. The higher altitudes of Yeta Pass are given 

 in the list. 



The outline figures of the four species of Eutliia described on p. 513, 

 were kindly drawn for me by Dr. G. H. Horn, and exhibit the specific 

 differences in a very characteristic manner.
