colored plates of Braconide accompany the fascicle. Future issues 
are to contain a discussion of the Chrysidide and Cynipide, the 
former by M. R du Buysson. This admirable series of monographs 
will prove indispensable to American students of Hymenoptera, and 
should be in every entomological library. 
Papers by Miss Murtfeldt.—The 1889 Report of the Missouri 
State Horticultural Society contains three excellent papers by Miss 
Mary E. Murtfeldt. The first, entitled ‘‘ Outlines of Entomology,” con- 
tains six chapters discussing the structure, habits, and transformations of 
insects ; the second, ‘‘ Our Insect Musicians,’’ is a popular discussion 
of an interesting subject ; and the third consists of the Report of the 
Committee on Entomology for the year. In the last reference is made 
to the injuries of Ceresa bubalus, Ceutorrhyncus napi, Lygus pratensis, 
and Gortyna nitela, each of which did considerable damage in Mis- 
souri during the year. 
American Tertiary Hemiptera.—Under the title ‘‘ Physiog- , 
nomy of the American Tertiary Hemiptera,’’ Mr. S. H. Scndder pub- 
lished a few months ago ë an important contribution to our knowledge 
of fossil Hemiptera. It consists of a summary statement of the results 
of the author’s extended study of thesubject, with remarks upon the 
relation of the American Tertiary Hemiptera to those of the present 
_ day, and to the Tertiary fauna of Europe. We have room only for the 
following generalizations: ‘‘(1) The general facies of the hemipterous 
fauna [of North America] is American, and distinctly more southern 
than its geographical position would indicate. (2) All the species are 
extinct, and. . . there is scarcely an instance where the same species 
occurs in two localities: (3) No species are identical with any Euro- 
pean Tertiary forms. (4) A very considerable number of genera are 
extinct, often including numerous species. (5) Existing genera’which 
are represented in the American Tertiaries are mostly American, not 
infrequently subtropical or tropical American, and where found also 
in the old world are mostly those which are common to the north 
temperate zone. A warmer climate than at present is distinctly indi- 
cated. (6) There are no extinct families. (7) The appearance of the 
same familes, and even of the same groups of genera, in the European 
and the American Tertiaries is common, but of the same restricted 
genus very rare. ?
