2 MISCELLANEOUS FOREST INSECTS. 



with this work the genus Pissodes has been studied in some detail 

 and many other genera of the Rhynehophora and other Coleoptera 

 have received attention in order that a broader knowledge of the 

 order, and of the division to which the Scolytidje belong, might be 

 acquired, but there has been no idea of specializing on any but the 

 Scolytidfe and possibly a few genera, like Pissodes, wliich are of 

 special interest in connection with forest entomology. 



The material which has served as a basis for this bulletin is that 

 collected by the writer between 1890 and 1902, that collected by him 

 and by the assistants in forest insect investigations, Bureau of Ento- 

 mology, between 1902 and 1907, and that found in the collections 

 of the United States Department of Agriculture and United States 

 National Museum, especially in the Hubbard and Schwarz collection. 

 Studies were made also of good series of specimens of 5 European 

 species sent to the Bureau through the kindness of Dr. R. Heymons 

 and Prof. H. Kolbe, of the Royal Zoological Museum of Berhn, and 



3 European species represented in the United States National Mu- 

 seum collection.

HISTORICAL REFERENCES. 



The name Pissodes (pitch-colored) was lirst proposed by E. F. 

 Germar (1817, p. 340) without description, but to include Khynchsenus 

 hufo Fab , , Lixus notatus Fab . , and Rhynchsenus pini L. Later (Germar, 

 1824, pp. 316-319) he described the genus, part of which was based 

 on the mouth parts of Pissodes pini and P. notatus, but among the 

 10 species described only one, P. nemorensis, has been retained.
